SOLVENT RED 49:1
Description
Solvent Red 49:1, also known as D&C Red No. 17, is a synthetic azo dye widely used in cosmetic and personal care products. This oil-soluble colorant imparts a vibrant red hue to various formulations, including lipsticks, nail polishes, and hair dyes. Its molecular structure consists of a naphthalene core with azo and hydroxyl functional groups, contributing to its color properties and solubility characteristics.
The colorant demonstrates excellent stability in most cosmetic bases and resists fading when exposed to light or heat. Its oil solubility makes it particularly suitable for anhydrous formulations and oil-based products. Solvent Red 49:1 is typically used in concentrations ranging from 0.1% to 5%, depending on the desired color intensity and product type.
While generally considered safe for cosmetic use, it's important to note that Solvent Red 49:1 is not approved for use in products that may come into contact with mucous membranes or in the eye area. Some regulatory bodies have restrictions on its use in certain product categories. Formulators should always consult current regulations and safety data when incorporating this ingredient into cosmetic products to ensure compliance and consumer safety.
