What it is & what it does
PEG-150 Pentaerythrityl Tetrastearate is a large-molecule aqueous viscosity-increasing agent used especially in surfactant systems.
WHAT IT IS: PEG-150 Pentaerythrityl Tetrastearate is a large-molecule aqueous viscosity-increasing agent used especially in surfactant systems.
HOW IT WORKS: It gives cleansers and shampoos controlled thickness, improves dispensing and can reduce watery run-off. CIR reports low skin penetration is expected because of its large molecular size.
WHY ITS ROLE MATTERS: Rheology modifiers, thickeners and film-forming polymers control how a cosmetic flows, spreads and stays mixed. A carefully chosen polymer can suspend particles, help prevent separation and make each application feel consistent, but that is primarily a physical formulation effect.
A REALISTIC EXPECTATION: A smoother finish or temporary film is not proof of biological wrinkle removal or deeper skin regeneration.
