A few days ago a friend challenged me to produce a perfectly white soap. They told me my soap leaves too much dark colored soap scum in their white bathroom and soapdish. I've been making cold processed soap for 5 years. And till now I've been using often fine cinnamon or cocoa powder to help the retention and absorption of the EOs in the soap. My last batch was really great, a masterpiece (I thought..) but it got some bad reviews due to it's deep dark color. Since then I've purchased white white kaolin powder to replace the cacao powder but I am curious what base oils to try so I don't get yellowing or greenish tint?? Normally I use Olive oil and Coconut oil plus a portion of vegetable oil.(.very clear white). The olive oil can't make white soap sadly.. Have any ideas? Thanks guys!
