Carmine is a food-grade, water-soluble powder. Mix a little powder with water. Very concentrated.
Carmine has a long history as a natural colour. It is obtained from the female Coccus cacti beetle.
Carmine provides a bright strawberry red shade. It is chemically a very stable colour and is unaffected by oxygen, light, sulphur dioxide, heat and water activity. It may precipitate under low pH conditions and concentrated blends of carmine with strongly acidic ingredients should be avoided.
Melt and pour soap: bright pink.
Cold process soap: light pink.
