Description

Ascorbyl Stearate is an ester of ascorbic acid (vitamin C) and stearic acid. It is used in various industries, including cosmetics, pharmaceuticals, and foods.

Antioxidant properties

Considerations

Ascorbyl stearate is not terribly stable, much like ascorbic acid. It doesn't pose many risks other than minor skin irritation. It is not widely used in cosmetics.
