Polyglyceryl-4 Laurate Description

A plant-derived or synthetic ester of a polymer of glycerin (known as polylglycerin-4) and lauric acid, a saturated fatty acid that can be found in coconut or palm oils. This versatile ingredient works as an emollient, emulsifier, and a mild cleansing agent (surfactant).

The safety assessment of this ingredient shows that it can also serve as a penetration enhancer; for example, it can improve ceramide penetration into skin.

According to one of its suppliers, in its raw form it is a clear or yellow syrupy liquid.

Polyglyceryl-4 laurate is considered safe as used in cosmetics by the independent Cosmetic Ingredient Review board and is considered to be a non-irritant. Typical concentration ranges are from 5–10%, although lower amounts may be used if necessary or if this ingredient is part of a blend.
