Luxury Goat Milk Soap: Recipe and Tutorial

Cee from Oil & Butter is my favorite soap blogger for many reasons. She is generous with her expertise and her ideas. Her soap looks incredible (and her photographs are beautiful). She is knowledgeable and friendly. She shared a recipe and tutorial for a Luxury Soap two years ago, and it looks so gorgeous that I have been dying to try it. In the spirit of Cee’s original post, I share my recipe, advice, and reflections.

Equipment

First, a quick note about grams as opposed to ounces. I use grams to measure the weight of my soap ingredients because grams are more precise than ounces, even if you are measuring tenths of an ounce. I always recommend that soapmakers use grams, and whenever I use a recipe someone else has posted, I convert it to grams using SoapCalc.

This recipe was adapted from Cee’s own Luxury Soap recipe. I removed the jojoba oil mainly because it’s terrifically expensive. I don’t have much of it right now, and I prefer to use it for leave-on products like lotions, like other soapmakers. It’s perfectly fine in soap, however, and I didn’t remove it because I thought it shouldn’t be used. Using it would certainly have added a bit of decadence to an already almost sinful soap, but I think the recipe is plenty luxurious without it, too. I didn’t have chamomile extract, so I didn’t use that either. Aside from removing the jojoba and chamomile extract, I tweaked the numbers of the other oils and swapped almond milk for coconut milk. Otherwise, the recipes are quite similar.

I began by preparing the oils. First, I measured out the butters.

Mango ButterMango butter is truly wonderful. It is similar to shea butter in some respects in that it has a significant amount of unsaponifiables, meaning that more of the conditioning and moisturizing qualities of the butter make it through the saponification process. It also contributes to a creamy lather.

Shea Butter I added the shea butter to the mango butter. I use shea butter and/or cocoa butter in almost all of my soaps because I love what it does for skin. It does speed up trace, so be careful.

Coconut OilIn with the coconut oil. It’s so hot here today that it’s completely melted already. Actually the mango butter was kind of soft as well. It’s usually a little harder (and almost brittle) than it was today. Coconut oil is great for bubbles—it contributes to fluffy lather and cleansing as well as bar hardness. I use coconut oil in almost all of my soaps.

Palm OilThe last hard oil is palm oil, which I use because it contributes to bar hardness, stable lather, and conditioning. I use it in a lot of my soaps.

What I like to do is put all my hard oils in the soap bowl together, then melt them in the microwave. It saves time as opposed to melting each separately and adding them together. I warmed these oils for about one minute (try 30-second bursts). At that point, the shea was almost melted, so I stirred it until it was completely melted.

Olive OilA quick word about olive oil: you can use any grade of olive oil in soap, but I always use pure golden olive oil. I don’t think it’s necessary to use extra virgin olive oil in soapmaking. In fact, it’s not different enough from pure golden olive oil to warrant its own category in SoapCalc, though olive oil pomace is. I personally don’t use pomace because pure golden olive oil is available at my local discount membership warehouse for a really good price (and no shipping). I use olive oil in every single soap I make. It’s highly conditioning and contributes to stable lather and bar hardness. I believe it to be the single best soaping oil there is.

Soft Oils

I prepared the soft oils—olive oil, avocado oil, and castor oil—measuring them out one at a time, and then adding them all to the melted hard oils and butters.

Avocado oil contains vitamins A, D, and E, and contributes to the bar’s conditioning properties.

Castor oil is the best source of ricinoleic acid and make the lather much fluffier and more stable. I use castor oil in most of my soaps. Castor oil is also a natural humectant, which means it draws moisture to the skin. I usually only use 5%, except in shampoo bars.

Mica Added

I added my Diamond Dust Mica to the sweet almond oil, mixed it with a small hand mixer, and then added the sweet almond oil to the rest of the oils. Sweet almond oil is another of my favorite oils. It contributes to a stable lather and conditioning bar. It works well as a carrier oil for colorants, too. It’s also great in lotions.

I blended the oils so that the Diamond Dust Mica would disperse. Look at that pearly sheen!

Diamond Dust Mica

I believe this mica is probably similar to Bramble Berry’s Super Pearly White Mica. That lovely, pearl sheen will not completely make it through the soapmaking process, but if you use it in melt-and-pour soap, you should see a nice shimmer in your soap. I do still notice a little bit of shimmer in cold process soap as well, and it definitely adds something that just plain titanium dioxide lacks.

Goat Milk and Coconut Milk

After my oils were prepared, I prepared my milks and lye. Why didn’t I do that before preparing the oils? Well, if I were using water, I would have prepared the lye mixture first because it needs time to cool. However, if I am starting with frozen milk, there is no reason to start with the lye mixture because it doesn’t need to cool. In fact, I find that I can control my milk and lye much better if I prepare it after the oils. I have found that if you prepare the milk and lye before the oils, the fats in the goat milk begin to saponify, and while that’s not necessarily problematic for any reason, I just find I like it better if the milk is still liquid. I used a 6% lye discount in this soap, but you could alter it to your preferred superfat if you like. I find 6% to be my personal sweet spot.

Lye MixtureWorking with milk requires a bit more effort than working with water. I use a stainless steel pot because if I need to quickly cool it down the mixture, stainless steel is a better conductor (hot or cold) than plastic or glass. I also add the lye to the milk just a little at a time and stir until the lye is dissolved. Then I add more. It can take a little while. Once all the lye was added, and I was relatively sure the all of it had dissolved in the milk, I added the sodium lactate to the lye mixture and stirred well to dissolve it.

Lye MixtureI checked the temperature of the lye mixture, and it was about 82°F. Pretty good. I don’t like it to rise above 90°F. If it starts to become too warm, I put the pan in a cool water bath to bring the temperature down.

Another benefit of preparing the oils first and then the lye mixture is that the oils have a little bit more time to cool down as well. I didn’t take their temperature, but my guess is that they were 90-95°F by the time the lye was ready. They would likely have been about 100°F when I began preparing the lye mixture.

Once the lye mixture was ready, I added it to the oils and stirred a little bit. Anne-Marie Faiola of Bramble Berry likes to pour the lye mixture down the barrel of her stick blender to reduce splashing and bubbles. I did that this time, too.

Stick Blending SoapI stick blended until a very light trace, then I added the honey. Honey will accelerate trace, so make sure you add it at a light trace, or you may find you have gone too far with the stick blending. When I use honey in soap, I mix it with an equal amount of distilled water. In this case, I used 1.5 t of honey, so I mixed it with 1.5 t of water. Then I microwave the honey for a very short time—only 5-10 seconds. I stir until it dissolves in the water. I find that I have fewer issues with scorching, overheating, and caverns in soap if I dissolve the honey. I have also learned not to use more honey than I need. I wouldn’t go higher than a tablespoon in a batch of this size, and given I used a log mold instead of a slab mold, even that much might have caused temperature issues. Honey is a natural humectant and contributes to the lather in soap.

I added my fragrance, which was Nature’s Garden’s Brown Sugar and Fig. I wanted a scent that evoked the creaminess of the soap. I chose this fragrance also because I knew that it had a very small amount of vanillin in it, and reviews said that it didn’t discolor. I love the fragrance description:

This magical, complex fragrance oil by Nature’s Garden is composed of top notes of fresh figs, peaches, and passion fruit; followed by middle notes of coconut milk, vanilla orchid, jasmine, muguet, and freesia; well-balanced with base notes of vanilla beans, caramel, maple sugar, fig leaves, and musk.

To be honest, I don’t smell any fruit notes, with the possible exception of the fig. I mostly smell vanilla, sugar, and musk. It smells great, and I think it’s perfect in this soap. I had no issues with acceleration or ricing. I’ll have to wait and see as the soap cures to determine whether the claims that it doesn’t discolor are true.

I should think other good fragrance choices might be Nature’s Garden’s Baby Bee Buttermilk or Oatmeal, Milk, and Honey or Bramble Berry’s Wildflower Honey (which will discolor, but to a nice honey shade).

TraceI blended to a pretty thick trace, then poured the soap into my 10-inch silicone loaf mold, which was the perfect size for this recipe. Bramble Berry recommends using sodium lactate to make it easier to remove soap from this mold, and in any case, sodium lactate adds a nice silky feel to soap.

Soap In the MoldLike Cee, I spooned soap on the top after doing a little bit of sculpting, but I didn’t think my tops were as pretty as hers, so I experimented a bit with a skewer to create a slightly different design.

Swirled Soap TopsI spritzed it with 91% isopropyl alcohol, which might not have been strictly necessary since I didn’t choose to gel the soap, but it can’t hurt anyway. Isopropyl alcohol can help prevent soda ash on the tops of soap, but it’s not 100% effective.

A quick word about gelling milk soaps. You will hear some soapmakers insist that you can’t or shouldn’t gel milk soaps. I don’t see any problem with it. I gel most of my milk soaps. Even the ones with honey in them, too. I have only had a problem with overheating once, and it was because I used way too much honey. My advice is to do what you want. I chose not to gel this one because I didn’t want it to darken as much as I knew it would if I gelled it. You might not need to insulate, or perhaps just to insulate lightly, but your milk soaps will gel just fine if you are mindful of the other additives you use and keep an eye on the temperature.

Cut Luxury SoapThe cut soaps smell wonderful. I am going to let them have a nice long cure and give them to family and friends for Christmas.

Milk Soaps

Milk soaps are so much fun to make, and there are so many choices. How do you know which kind of milk to use or even how to use it? It depends on what qualities you’re looking for in your soap.

Coconut MilkCoconut Milk

Coconut milk is possibly my favorite milk to use in soap, and it is also one of the easiest. Some of the qualities I have noticed are a tendency to increase fluffy lather with big bubbles and to lighten the color of the soap. Most milk soaps will be a bit darker than water-based soaps, but coconut milk soaps look lighter than water-based soaps to me. Coconut milk soaps feel creamier than water-based soaps as well. I use coconut milk just like I use other milks: I freeze the milk and add the lye a little bit at a time. The handiest method might be to measure it out in ice cube trays, freeze it, and then just use the amount you need. I think that coconut milk behaves a little better than other milks. It doesn’t tend to discolor, like goat milk will, and it is a lovely creamy white right up until you add it to the oils. I have noticed that like other milks, the lye will begin to saponify the fats in the coconut milk, so I tend to give it a stir every few minutes until I’m ready to add it to my oils just so that it stays smooth. However, I haven’t had any problems when I’ve added thicker, partly-saponified coconut milk to my oils. I use coconut milk in several of my soaps. I recently used it in a Creamy Coconut soap (along with real cream) that turned out very nice.

Creamy Coconut

Goat Milk

Goat milk is the soap maker’s standby, and it’s fabulous in soap. It comes in three kinds: fresh, condensed, and powdered. I have used all three, and I prefer using it fresh or powdered. My experiments with condensed milk did not go as well. I think it discolors more than fresh goat milk, too. If you do use it, make sure you remember that you need to add equal parts water. Most soap makers who use it will reduce the amount of water for a recipe by half and mix that with their lye, making up the other half of their liquids with condensed goat milk.

Fresh goat milk works best when it’s frozen, just as I described with coconut milk. Add the lye to the frozen milk a little bit at a time, stirring well until the lye is dissolved each time. If you keep the temperatures low, making use of ice water baths when necessary, goat milk will discolor less, but it will still discolor. I happen to think naked goat milk is rather pretty.

Lilac Goat Milk Goat milk produces a creamy, moisturizing bar of soap. It can be used raw or pasteurized. I haven’t noticed if it affects the lather much, but it does feel nice on your skin.

I also used powdered goat milk in some of my soaps. I add the powdered milk directly to my oils and stick blend it in to combine it until it is well incorporated, and I can’t see any clumps. I have never had any problems using powdered milk in this way, though I have heard some soap makers actually mix up the goat milk powder with water and then freeze it, just as with fresh goat milk. Some soap makers also add the milk powder at trace. Powdered goat milk still adds creaminess to the soap, but it’s much easier to use than fresh goat milk.

Cow Milk

I have used cow milk in my Chocolate Milk bars. It works fine, and I liked it, but I do feel that goat milk adds a certain extra something that cow milk doesn’t. I recommend using whole milk when using cow milk. It should also be frozen and mixed slowly with the lye. I noticed that while goat milk tends to turn an orangey shade when it is getting too hot, cow milk turns more yellow.

Almond Milk

I recently made my own almond milk and used it in a new Sweet Almond and Honey soap, and I loved it. The soap has a fluffy, bubbly lather and smooth feel. There are too many variables to say for certain the almond milk made all the difference—I also used more sweet almond oil than I typically do, and the soap has honey it in, which likely contributed to the wonderful lather.

Sweet Almond and HoneyI used almond milk in the same way as I did every other milk: I froze it and added the lye slowly to the frozen almond milk. I noticed this milk, like coconut milk, stayed whiter, but it did not saponify with the lye that I could tell, and it could be that it has less fat. It was nice to work with, and I’d do it again.

Yogurt

Yogurt is wonderful in soap. I use full fat plain yogurt and mix it with an equal amount of water to thin it. Then I freeze it and use it like I would any other milk in soap. It truly adds a luxurious feel to the soap. It feels smooth and creamy. I think some soap makers add yogurt to their oils either before adding the lye or at trace, but I haven’t tried that yet, though I have used yogurt powder in my oils, and it’s very nice—similar to goat milk powder.

Buttermilk

I like using buttermilk powder in soap more than fresh buttermilk, but that’s just because it’s a little easier. Buttermilk has alpha hydroxy acids that are very good for facial soaps. I use it in my Lavender Chamomile facial soap.

2013-06-08 11.53.56This is a very nice facial soap for a lot of reasons, including the oil combination, the chamomile-infused olive oil, and the French pink clay and lavender essential oil, but the buttermilk contributes very nice qualities to it.

Cream

Cream is amazing in soap. I have not tried substituting all my water for cream, but I have tried adding cream to my oils before adding the lye, and it results in a very nice, luxurious feel.

Coffee and CreamIn my Coffee and Cream soap, I mixed cream with the white part you see marbled through the soap, in addition to the coffee you see in the brown part. It was a little bit of juggling, but the bar is so amazing! It smells and feels incredible.

If you want to learn more about making soap with a variety of milks, I highly recommend Anne L. Watson’s book Milk Soapmaking.

Lavender Chamomile Facial Soap

I recently made a new facial soap designed to be kind to dry, mature, and/or sensitive skin. Volunteers tried the soap, and based on their feedback, I plan to add it to my regular line.

Lavender Chamomile Facial SoapI have decided to call this soap Lavender Chamomile Facial Soap. You will likely not smell the chamomile flowers in the final soap, but you will feel the benefits. I infuse the olive oil in the soap with chamomile, which imparts soothing properties to the olive oil. The soap also has lavender essential oil, a 100% natural fragrance that is used in aromatherapy for its calming qualities. French pink clay cleanses and clarifies the skin, removes dead skin cells, and creates and overall refreshed appearance. Buttermilk also helps clarify the skin and helps remove dead skin cells. Lavender Chamomile Facial Soap contains rich shea butter, chamomile-infused olive oil, coconut oil, rice bran oil, apricot kernel oil, avocado oil, and castor oil. In addition to all these goodies, this soap is made with coconut milk, which is cleansing, but not drying or irritating. The fatty acids in coconut milk help to eliminate dirt, impurities, dead skin, and other blemish-causing materials, but they also increase hydration and replenish moisture in your skin.

In other words, this soap is chock full of goodies for dry, mature, and/or sensitive skin!

Here is what the beta testers had to say about this soap:

  • “I’ve used the soap twice a day for over a week. It lathers well for a facial bar. When I rinse my face then dry it my skin is tight for about a minute, then it feels so soft.”
  • “As far as I’m concerned you have a winner. I love it and would buy it!!!!”
  • “Oh I love this soap! Its very creamy and smells very good! It does not leave my face dry. I do not need moisturizer after. I love it!”
  • “I’ve been using your facial soap for around two weeks now and truly love it! After washing my face, my skin barely feels tight at all! It smells great and leaves my skin feeling so soft and smooth.”
  • “I enjoyed the way it made my skin feel clean without drying it.”
  • “When washing it feels so smooth, then when my face is dry there is some tightness, but I put a small amount of moisturizing cream on, and it is perfect.”

Two testers have also reported that some mild skin irritations have cleared up since trying the soap. I cannot guarantee you will have the same results. Any soap will probably make your skin feel tight initially, but the testers seemed to say over and over that this feeling is much more temporary with Lavender Chamomile Facial Soap and that they are loving the way their skin feels.

If you do use this soap, I recommend that you still use a bit of moisturizer if your skin is very dry. Try using the soap without moisturizer for a few days to see whether or not the soap alone is conditioning enough for your skin.

UPDATE: You can pre-order this soap from the Etsy store.

Here are the making and unmolding videos of the making of this soap. I will be making a new batch this weekend, so you can look for this new facial soap in my store soon. Let me know if you would like to reserve a bar.

Swirling Success

I’ve been trying for some time to swirl two colors together with no success, but I finally did it!

Coconut Lime VerbenaI created this soap because I didn’t have enough lemongrass essential oil to make a second batch of Lemongrass Sage today. Lemongrass Sage has turned out to be my most popular soap. I sold out of the supply I brought to a recent craft fair at my school, and I have sold several bars of it over this Thanksgiving weekend. I have to admit, it’s a great soap, and I use it myself on my face.

At a loss as to what type of soap to make, I decided to try something new. I had a coconut lime verbena scent I had been meaning to try, and I had some green colorant left over from making the Cucumber Yogurt batch (as it turns out, I needed to use a lot more colorant to make the soap look greenish), so I decided to try swirling again.

Ingredients:

  • 30% olive oil
  • 25% coconut oil
  • 25% palm oil
  • 10% avocado oil
  • 5% cocoa butter
  • 5% castor oil

Coconut Lime VerbenaI started to use yogurt as a base when it occurred to me I should try coconut milk instead because of the coconut lime verbena scent. I knew I wanted the white part of the soap to be as white as possible without using titanium dioxide (I don’t have any). My shea butter is raw, unrefined shea butter, and it has a yellow cast that makes my white soaps a more yellow shade of cream. The cocoa butter I have is white, and I noticed when I used it to make the Vanilla Sugar Cane soap that the soap batter was much whiter than normal, though because of the vanillin in the fragrance I used, the soap later turned a browner color. So, I decided to use cocoa butter in this recipe when I usually use shea. On a whim, I also decided on avocado oil instead of sweet almond or a full 40% olive oil. No particular reason aside from wanting to experiment. Avocado oil is good for people with sensitive skin, and it has vitamins A, D, and E.

I mixed the oils with the coconut milk and lye, added the fragrance, and divided the batch in half. I colored one half. By the time I had the colored portion ready, the white portion had already reached the consistency of very thick pudding, or perhaps mashed potatoes like I make them (whipped potatoes, really). I started to lament a little bit, thinking of my Amy Lowell Lilac Soap, when I remembered a swirling technique I learned on YouTube:

The swirling technique Celine described saved my soap! I think it turned out gorgeous. It smells heavenly. I can’t wait to try it with another kind of soap. One of the interesting things about swirling is that each time the soap is different. Each individual bar is different. You just don’t know what you will get. I’m very pleased with how the soap turned out.

Coconut Lime VerbenaThe soap is beautiful, and I love the coconut lime scent. I’m also proud of the way the soap itself turned out with the coconut milk base. I admit I was excited about the idea when I remembered I had some frozen coconut milk I could use.

Fun New Soaps

I’ve been trying some fun things with purées, ideas I learned about in Heidi Corley Barto’s The Natural Soap Chef. The first soap is a banana/coconut milk purée-based soap scented with Bramble Berry’s Monkey Love fragrance oil, a recipe you can find in Barto’s book. She calls it Bananas Foster, but I like Funky Monkey better.

Funky MonkeyYou can see little flecks of banana in the soap. It has a sort of interesting, uneven color that might be the result of a partial gel, but it doesn’t look as dramatic as some of the partial gel images I’ve seen of other soap, so I’m not sure. I decided to try to prevent this soap from gelling and put it in the fridge because my previous milk soaps had not turned out well, and this one seemed to be kind of cranky as I was mixing the lye. I like the way it turned out. It smells great, and I think it is going to be a very nice soap to use.

This next soap has an interesting story. Pumpkin pie soap was one of the first soap ideas I ran across that I told myself I HAD to make, and I believe I first encountered it on the Lovin Soap Blog, but it’s a hot process recipe, and I prefer cold process. However, the Soap Queen also has a great CP pumpkin purée soap tutorial. Heidi Corley Barto also has one in The Natural Soap Chef.

Pumpkin Pie Soap

Meet my Pumpkin Pie Soap! I didn’t come up with the idea, but I used my own recipe and technique for producing it.

Ingredients

  • 35% olive oil
  • 25% coconut oil
  • 25% coconut oil
  • 10% shea butter
  • 5% castor oil

I share the percents because I think it’s easier to make the recipe for your own mold if you know percents. You would then just use a lye calculator to figure out how much lye, water, and pumpkin purée to use.

In my soap, I used One Pie Pumpkin.

One Pie PumpkinOne Pie Pumpkin is very special pumpkin. Yankee Magazine calls it New England’s unofficial brand. It isn’t available widely outside of New England, and some of my research indicates that some areas only sell it seasonally during fall and winter for Thanksgiving and Christmas. I haven’t lived in Worcester, MA long enough to find out if that is the case here, too, but I intend to find out. If it is, this could be one very special soap. I really like that the recipe uses an old New England product that been used for generations. It makes the soap more interesting to me. I halved the amount of water called for by the recipe and mixed my lye with water, then I made up the remaining amount of water with One Pie Pumpkin. My recipe called for 5.61 oz. lye and 13.18 oz. water, so I used 6.59 oz. water and 6.59 oz. pumpkin purée. I added the pumpkin directly to the oils and stick blended the mixture to combine, then I added the lye/water and stick blended to a light trace. It blended fairly quickly.

I used Bramble Berry’s Pumpkin Pie fragrance oil for scent. It smells great. I did notice that it accelerated trace in my own soap, so add it at a fairly light trace. I actually didn’t need to stick blend anymore after I added it. Next time I make it, I might add my pumpkin pie spice to the soap and stick blend it before I add the fragrance oil just so the spice is incorporated fully. I had not intended to gel the soap, but it was gelling in the fridge anyway, and it was starting to develop a crack, which I fixed. Since I figured it would gel anyway, I took it out to prevent a partial gel. I don’t have anything to compare it to, since I haven’t made this soap before, but I think gelling it gave it a really nice, rich pumpkin color. The soap looks great and smells amazing. I love many of the soaps I’ve made, but I think this one might be my favorite, just because it smells so great and was so much fun to make, and it also has this interesting New England connection. I can’t wait to use it.
