Water based colours are water-soluble artificial Colours used for Solid Soap, Liquid Soap and water-based products like Hair Shampoo and Bath Foams.
Aqua; CI 19140; Phenoxyethanol, Ethylhexylglycerin
Because water based colours don't sink to the bottom when mixed with liquids, they are the best choice for liquid products that have a low viscosity.
The water based colours are very concentrated - the more you put in, the stronger the colour! You need just 2-6 drops per 100 grams or millilitres for the other water based colours but you need double the amount for yellow so 4 – 12 drops per 100g or mls. Mixing two or three primary colours gives you other colours. These Liquid Colours are not light sensitive and do not discolour your sink or bath.
Water-Based Colours (WB) can easily keep without fading for 7 years in an airtight container; just don’t store them in direct sunlight. They’re best stored in a dry and dark place.
