Science & Benefits

PEG-150 Distearate is a polyethylene glycol diester of stearic acid. In skincare, it is primarily used as a high-efficiency thickening agent for surfactant systems (cleansers). It also provides a mild humectant effect, ensuring that cleansers do not leave the skin feeling stripped or dry. While it contains a stearic acid backbone, its high molecular weight and ethoxylation make it significantly less comedogenic than pure stearic acid. Its rating of 2 indicates a low risk for most users. It is an effective functional ingredient that helps maintain the viscosity and 'rich' feel of acne-safe cleansers without causing significant follicular occlusion.
