TKB Neon Yellow Concentrate
While it is non-toxic, the color is not cosmetic grade and so should not be used in personal care products.
Our color concentrates are water-soluble pigments or dyes suspended in vegetable glycerine. 1 fl.oz. should color about 20 pounds of soap to a medium shade.
Warning: This color is particularly sensitive to high temperatures. If it is overheated it will clump and that clumping is irreversible. Please keep temperatures below 170 F. The pigment is also sensitive to exposure to alcohol. If you spritz it with alcohol, it will clump at any temperature. Please do not spray the product with alcohol.
