An emollient and emulsifier with PCA. It softens skin, blends oil with water and holds moisture. Well tolerated.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A functional emollient and emulsifier. Safe.
Glycereth-25 PCA Isostearate is a multifunctional ingredient that combines emollient and emulsifier properties. It helps bind the water and oil phases of creams and lotions, softens the skin, and through its PCA part adds extra water-binding capacity. On efficacy: a functional formulation ingredient rather than a treatment active. Its main value is a stable texture, a soft feel and good product spread. The PCA fraction, a natural moisturizing factor of skin, adds some water retention, but the skincare contribution is secondary to its emulsifying role. Don't expect a standalone active effect. Topical use during pregnancy and breastfeeding poses no problem. Tolerance is high, with low irritation and allergy potential. Suitable for sensitive skin. Not comedogenic at typical use levels.
