What is Ester used for?

Esters are often found in skin care cosmetic formulations. They are sometimes chemically more stable than the acid or alcohol compounds from which they are derived. They are also often more oil soluble and less hydrophilic than their individual alcohol or acid components. This sometimes means that they are better able to penetrate the skin epidermis than the corresponding alcohol or acid compound.

General safety info about Ester from CIR

The CIR Expert Panel assessed the safety of 239 alkyl esters for use in cosmetics, finding that these ingredients are safe in cosmetic formulations in the present practices of use and concentration when formulated to be non-irritating. The alkyl esters included in this assessment have a variety of reported functions in cosmetics, with skin conditioning agent being the most common function. The Panel reviewed available animal and clinical data in making its determination of safety on these ingredients, and, where there were data gaps, similarity in structure, properties, functions and uses of these ingredients allowed for extrapolation of the available toxicological data to assess the safety of the entire group.
