Sorbitan Sesquiisostearate
What is Sorbitan Sesquiisostearate?
Sorbitan Sesquiisostearate is an ester derived from sorbitol and isostearic acid, commonly used in the cosmetics industry. It is created through the chemical reaction known as esterification, which combines sorbitol, a sugar alcohol, with isostearic acid, a type of fatty acid.
This compound is primarily used as an emulsifier, helping to stabilize and maintain the mixture of oil and water in products like makeup and skincare items. There is limited research focused on its health impacts when used in cosmetics, but it is generally regarded as safe for topical use by regulatory bodies.
Commonly found in: Makeup, Skincare creams, Lotions, Sunscreens
