Mechanism of Action
POLY(1,2-BUTANEDIOL)-55/PEG-90 PENTAERYTHRITYL ETHER fundamentally modulates rheology, influencing the flow and thickness of cosmetic products. By increasing or decreasing viscosity, it helps achieve desired product textures and spreadability. In addition, it enhances overall product consistency and can draw moisture into a formulation as a humectant. As a derivative of polyethylene glycol (PEG), it may also contribute to emollience, emulsification, surface-active properties, and conditioning benefits.

Stability
Polyethylene glycols, including this derivative, are generally well-tolerated and resist microbial degradation, often obviating the need for additional preservatives. The solubility in water and ability to absorb moisture (hygroscopicity) of polyethylene glycols are observed to diminish with increasing molar mass.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl PEG/PPG ethers, which encompass this ingredient, are safe for use in cosmetics when formulated to ensure they are non-irritating. Polyethylene glycols are broadly considered safe for topical application, demonstrating minimal irritation to human skin and no evidence of sensitizing, mutagenic, or carcinogenic effects.
