A cosmetic composition comprising a colorant composition comprising:
- (a) a first component comprising a salt of (sulfonatophenylazo) naphthoate;
- (b) a second component comprising a salt of (phenylazo) naphthalenedisulfonate, the first and second components in a weight ratio of 5:1 to 3:1, the colorant composition mimics the color of cochineal red and is stable for at least one week when stored at 45° C.;
- wherein the cosmetic composition further comprises 4-ethyl resorcinol, retinyl propionate, or a mixture thereof.
A cosmetic composition comprising a colorant composition comprising:
- (a) a first component comprising a salt of (sulfonatophenylazo) naphthoate;
- (b) a second component comprising a salt of (phenylazo) naphthalenedisulfonate, the first and second components in a weight ratio of 20:1 to 10:1, the colorant composition mimics the color of cochineal red and is stable for at least one week when stored at 45° C.;
- wherein the cosmetic composition further comprises 4-ethyl resorcinol, retinyl propionate, or a mixture thereof.
A cosmetic composition comprising a colorant composition comprising:
- (a) a first component comprising a salt of (sulfonatophenylazo) naphthoate;
- (b) a second component comprising a salt of (phenylazo) naphthalenedisulfonate, the first and second components in a weight ratio of 3:1 to 2:1, the colorant composition mimics the color of cochineal red and is stable for at least one week when stored at 45° C.;
- wherein the cosmetic composition further comprises 4-ethyl resorcinol, retinyl propionate, or a mixture thereof.
A method of producing a colorant composition mimicking cochineal red and that is substantially free or free of dried insect comprising the step of combining (a) a first component comprising a salt of (sulfonatophenylazo) naphthoate and (b) a second component comprising a salt of (phenylazo) naphthalenedisulfonate, wherein the first and second components in a weight ratio of 5:1 to 3:1.
