D&C Red 7 ca Lake/L19-0793/0792/0770

D&C Red 7 Ca Lake (also known as D&C Red No. 7 Calcium Lake) is a synthetic colorant derived from D&C Red No. 7, which is a water-soluble dye, but the "lake" form is insoluble in water and is used in applications where a dry or stable pigment is needed. It is used in cosmetics and personal care products, especially where a vibrant red color is required. The addition of calcium salts to form the lake makes the pigment more stable and easier to incorporate into various products.

Here’s a detailed description and usage information for D&C Red 7 Ca Lake:
