Retinyl palmitate
Retinyl Palmitate
Retinyl palmitate (pronounced: ret-in-yl pal-mi-tate), also known as vitamin A palmitate, is an ester of retinol (vitamin A) and palmitic acid, with formula C36H60O2.
Etymology
The term "retinyl palmitate" is derived from its two components: "retinyl", which is a derivative of "retinol" or vitamin A, and "palmitate", which is derived from "palmitic acid", a common saturated fatty acid.
Description
Retinyl palmitate is a yellow, crystalline solid that is slightly soluble in water. It is one of the most commonly used forms of vitamin A in skin care products, due to its stability and gentle nature. It is converted into retinol in the skin, which then converts to retinoic acid, the active form of vitamin A.
Uses
Retinyl palmitate is used in a variety of cosmetic and pharmaceutical products, including skin care products, vitamin supplements, and over-the-counter medications. It is known for its antioxidant properties and its ability to promote healthy skin.
