Ascorbyl Palmitate - Stable Vitamin C

Description

This derivative is the form most commonly used in cosmetic products because it does not irritate and is much more stable than vitamin C.

It is a synthetic ester of Vitamin C (Ascorbic Acid), formed from the latter and palmitic acid to create a fat-soluble form of Vitamin C.

This fat-soluble form is a powerful antioxidant on its own, although its effect can be enhanced by combining it with Alpha-tocopherol (Vitamin E). Together, they form a powerful depigmenting combination for sun spots or age spots. A mixture of five parts ascorbyl palmitate and one part Alpha-tocopherol is more effective.

It is an odourless, yellowish-white powder. It is slightly soluble in water, more soluble in 96% ethanol and slightly soluble in fatty oils. Its alcohol solubility allows it to be used in aqueous and non-aqueous systems and emulsions.

It is incorporated into the oil phase and is usually combined with other antioxidants (BHT, citric acid, etc...).

It is usually very stable, as it is less sensitive to oxygen.

It has properties that help stabilise emulsions.
