Spotlight on Ingredients: Kaolin Clay

Kaolin ClayI use kaolin clay in most of my soaps. Kaolin clay is a natural and gentle clay that is kind to sensitive skin but also adds slip and silkiness to soap and helps the soap’s fragrance “stick.” Some fragrances, especially citruses, don’t fare well in the harsh environment of the chemical process involved in soapmaking. Kaolin clay gives the fragrance something to “cling” to and helps the soap better retain the scent. Kaolin clay is such a fine powder that it adds the mildest exfoliation to the soap, and it’s one of the clays that works well with all skin types. Dry kaolin feels like a smooth, fine powder and is often used in cosmetics and face masks. Kaolin cleanses and detoxifies, so it really does add a little something special to soap.

I use a bit more than a teaspoon of kaolin per pound of oils in most of my recipes that don’t include other clays. For instance, in my Marseilles-style soap, which I call Provence, I use French green clay, and adding kaolin in addition would make the soap crumbly and chalky. Because the kaolin clay in my soaps is used throughout the bar and not as a colorant for a swirl, I simply add it directly to my oils before I add my lye water, and I stick blend it well to make sure the clay is dispersed and no clumps remain; however, I should add that I have not noticed that kaolin clumps a lot, unlike some other clays. You can use up to a tablespoon of clay per pound of oils, but my own experiments with clay in those amounts produced a chalky soap. Your own experiments may yield different results. My own experience is that soap with clays, including kaolin clay, feels smoother and silkier without any detrimental effects on the amount of lather.

Bonus: a picture I took just today of my Johnny Appleseed Soap, which like my other soaps, has a little over a teaspoon of kaolin per pound of oils.

Lavender Romance Soap

This month’s challenge in the Soap Challenge Club hosted by Amy Warden of Great Cakes Soapworks was to create a soap with a Holly swirl. The Holly swirl is named for its inventor, Holly Bailey, of Missouri River Soap Company. She makes excellent soap and generously shares her techniques on her YouTube channel. You can read her blog here or follow her on Facebook here. The technique is a swirl within a swirl—an in-the-pot swirl of two or more colors coupled with a drop swirl with an additional color. Here is the video Holly made when she tried the swirl for the first time:

Holly mentions in the video that vertical soaps really make this design shine, and it’s true, but I don’t have an appropriate mold for vertical soaps, so I improvised with my standard mold.

Lavender Romance Soap

I used a fragrance that discolors, but I didn’t want it to wreak havoc on my swirls, so I only added it to the black part, colored with activated charcoal. The activated charcoal was a little gray when I first cut the soap, but as the fragrance has darkened, so has the black in my soap. I think it has a sexy look that goes together well with its sexy scent, which is a blend of rustic amber with bold Parisian lavender and a mysterious black myrrh, sweet vanilla tonka bean, and a splash of Egyptian musk rounded out with raw clary sage. I received it as a free sample from Bramble Berry in one of my earliest orders with the company, and I immediately used it to make solid perfume. It smells gorgeous! It’s quite possibly one of my personal favorite fragrances, and I just can’t wait to try this soap!

I used ultramarine violet oxide and titanium dioxide to color the swirls, and they turned out well. The fragrance has not migrated very much to the swirled parts of the soap, so they have remained vibrant. The slight discoloration that did occur in some places only adds to the sexy, smoky appeal of the soap (in my opinion, at least).

As you can see, the tops have a mica swirl done with purple and white micas. I did not gel this soap because I didn’t want to risk glycerin rivers in the titanium dioxide. Also, when I work with a new fragrance, I find that not gelling is sometimes smarter because the soap is less likely to do crazy things in the mold.

This soap also taught me to love using activated charcoal in my soap. It is so much fun to see how it looks in the soap batter and the finished soap. It can go gray if you do not use enough, so you need to experiment to determine how much you might need to use.

The Holly swirl technique is fun, and I would definitely recommend trying it, even if you are relatively new to swirling. It was not as complicated as the mantra swirl or the peacock swirl, and I liked the results a lot better, too.

Soap Challenge 2013: Week One—Tiger Stripe Swirl

I am excited to be participating in Great Cakes Soapworks‘ 2013 Soap Challenge. Each week offers soapers the opportunity to try a different challenge. The challenge for the first week was to create a soap with a tiger stripe swirl. Of the various challenges planned, this particular technique is the only one I’ve tried. I think it is nice to get my feet wet with the familiar.

Spearmint Stripe

I made spearmint-scented soap I am calling Spearmint Stripe. The soap may have been a bit too thin to do a true tiger stripe swirl. Some of the layers broke through a bit, and others seemed a bit wider than I was looking for. However, I am happy with the way it looks, which is exactly like it smells. My inspiration for the colors was the green and white  spearmint candies similar in appearance to peppermints. The colors came out exactly as I wanted, and the soaps smell delicious.

The soap is chock full of goodies for your skin: olive oil, coconut oil, palm oil, sweet almond oil, cocoa butter, and castor oil and a kiss of buttermilk and kaolin clay with a whisper of pure silk.

I just love the way it smells. The spearmint fragrance blends well with other fragrances, but it smells delicious on its own, too. I have noticed, as I said in one of the videos, that this fragrance seems to fade, but it pops back in wet soap, so when you shower with it, you may notice the spearmint scent more than in the dry bar. I am not sure why that is, but as smelling it in the shower is the whole point, I am happy.
