CKM44 Posted August 29, 2015 Share Posted August 29, 2015 I made some goat milk soap and tried to swirl in some colors. It turned out pretty cool but after one week the color has really faded. I am not sure why unless I should have kept it in a cool dry place? Quote Link to comment Share on other sites More sharing options...
Jcandleattic Posted August 29, 2015 Share Posted August 29, 2015 Cool, dry, dark place wrapped tightly. That's the best when it comes to M&P Quote Link to comment Share on other sites More sharing options...
TallTayl Posted August 30, 2015 Share Posted August 30, 2015 What colorants did you use? Quote Link to comment Share on other sites More sharing options...
CKM44 Posted August 30, 2015 Author Share Posted August 30, 2015 I used some colorants I got from Micheals, just basic red, blue yellow. Not sure what brand. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted August 30, 2015 Share Posted August 30, 2015 Liquid? Often hobby store pigments are not stable in high pH or ultraviolet light. Quote Link to comment Share on other sites More sharing options...
emilyspoppy Posted October 7, 2015 Share Posted October 7, 2015 The advice you've gotten so far is very appropriate for CP soap which is, I believe the product that these very talented soapers primarily produce. Melt & Pour soap has special issues that differ from cold-processed soap when colorants are used. Most decent liquid colorants are stable and non fading when used alone in M&P, but the colors will blend or "migrate" when two or more colors are used. Liquids are easiest to work with, but if you want to mix colors you will need to use "non-bleeding" colorants. "Oxides" are primarily used for this purpose. They can be obtained from most decent soap making suppliers. I get mine from Brambleberry and WSP and other sources. Just make sure that you purchase "Non-Bleeding" colors. Most likely you will need to dissolve the dry colorant in alcohol, water or glycerin before using them. You will need to watch out for clumps and specks of colorant. Each supplier usually will have recommendations for mixing and usage on their site. HTH Dave Quote Link to comment Share on other sites More sharing options...
