The Fairest of Them All

If you look at the photos of the soaps I’ve made since I started blogging last May 2013, you may notice that I never had one that was a perfect white. Even the ones with titanium dioxide (TD) were off-white, partly because of the fragrance or essential oils used and partly because of the carrier oils.  Achieving a white-white soap was not important to me, so I always used less TD than the recommended 1 tsp per cup of soap.

Early last month I made soap with 95% olive oil and 5% virgin coconut oil that I named Fil-Castile. It didn’t contain any TD but it turned out a gorgeous white which came as a complete surprise.  The only problem I had with it were the pockmarks.  I tapped the stick blender to “burp” the oils but somehow I still got a lot of trapped air bubbles.

First batch of Fil-Castile Soap made last May. Notice the pockmarks from the trapped air bubbles.

Because of the high amount of olive oil, the Fil-Castile soap batter takes more than an hour to reach trace. When I made another batch a week ago, I did not immediately pour the batter into the mold after stick blending it into an emulsion. I left it in the mixing bowl while I made other soaps, hand stirring it every now and then. After about an hour or so, the batter finally reached light trace – similar in consistency to light creme anglais. I slowly stirred it for another couple of minutes before pouring into the mold.

The result is soap as smooth and fine as porcelain. It still has a few air bubbles, but hardly noticeable.

New batch of Fil-Castile Soap: perfectly smooth.

I get it now why it’s important for some soap makers to achieve a white-white soap.  It is beautiful in its simplicity and purity.  Just to see what kind of white I could get using TD at full dosage, I made a batch using a normally off-white formula containing olive oil, coconut oil, palm oil and cocoa butter.  I chose a clean-smelling yet feminine FO that is colorless and non-discoloring. It has notes of ozone, watery greens and white florals: smells soooo good! I am calling it Aqua, and for Christmas, I am thinking of adding some peppermint and/or eucalyptus and naming it Snow.

Aqua: perfectly white using 1 tsp TD for every cup of soap batter

Fil-Castile is almost as white as Aqua, but the TD in Aqua makes it brighter. Here they are side by side:

I wish you all a happy week. 🙂
