Mica is a food colouring
Micas are pigments used in the cosmetic industry to give a large range of colours to cosmetics. They can be coated with colourful pigments in a lab to create vibrant colours, you can find some examples of micas at this link https://tinyurl.com/yahzsfqz. The micas made for CP soap are made especially to resist the alkalinity of the soap. Even so sometimes they morph colours.
Food colouring is created especially to be used to colour food such as cupcakes frosting (you can see more about food colouring at this link https://en.wikipedia.org/wiki/Food_coloring). Food colouring is made especially to be used in foods, and in most countries there are strict regulations on how food colouring is made, as because it’s part of food it will end up being ingested.
So micas are not food colouring, and I do not recommend replacing them with each other and using micas in food, or use food colouring in soap.
