PEG-4 Laurate is a polyethylene glycol ester of lauric acid. It is used in cosmetics and personal care products as an emollient, surfactant, and solvent. It is also used in some industrial applications. PEG-4 Laurate is derived from lauric acid, a naturally occurring fatty acid found in coconut oil. It is also used in Olaplex No. 5 Bond Conditioner as an emollient.

PEG-4 Laurate may cause skin irritation, allergies, and immunotoxicity. It may also be toxic to the sense organs. In short-term feeding studies, PEG Laurate ingredients were irritating to the gastrointestinal tract, but not necrotizing. In chronic oral toxicity studies, there was some evidence of liver damage and hyperplasia in several tissues.
PEG-4 Laurate should be used with caution in people with sensitive skin. It should also be avoided by people with allergies to polyethylene glycol or lauric acid.
