Octyldodecyl Stearoyl Stearate description

Octyldodecyl stearoyl stearate is an ester that functions as a skin conditioning and viscosity-increasing ingredient in cosmetics. It may be animal-derived or synthetic and its use in products such as moisturizers adds noticeable cushion, enhances spread, and promotes a long-lasting smooth feel. The independent Cosmetic Ingredient Review panel ruled octyldodecyl stearoyl stearate safe as used in cosmetics, where at the time usage concentrations ranged from 2-15%. As of September 2022, the panel reopened its report because of an increased concentration of use. In its raw form, octyldodecyl stearoyl stearate is an amber colored liquid.
