Colorants required for household and personal care products.
Good afternoon everyone. It is a pleasure being here on this forum.
I have a doubt regarding the usage of colorants for making liquid hand soap, liquid dish-wash, liquid disinfectants etc. We are using food grade colorants in the manufacturing of aforementioned products (for e.g Carmoisine 20%). We are experiencing loss of color after a few days. The color of the product (for e.g liquid hand soap) either fades away or vanishes completely. Is it due to the fact that we are using food grade colorants ???
I hope I get valuable suggestions for the above query.
