PPG-1/PEG-1 STEARAMINE.

Valuable / ANTIMICROBIAL

PPG-1/PEG-1 STEARAMINE is a multifaceted ingredient serving as both an antimicrobial agent and an amphiphilic surfactant. Its unique molecular structure, encompassing hydrophilic and lipophilic components, enables effective cleansing, emulsification, and overall product stability. It's broadly utilized across various cosmetic formulations.

Antimicrobial Surfactant Emulsifier Solubilizer Solvent

Science

Mechanism of Action

This ingredient functions primarily by controlling microbial proliferation, specifically against bacteria and fungi, thereby contributing to product preservation and skin hygiene. Its amphiphilic nature, derived from polyethylene glycol (hydrophilic) and polypropylene glycol/stearyl (lipophilic) parts, allows it to effectively encapsulate sebum and impurities. This mechanism facilitates their suspension and removal during cleansing. Additionally, its polypropylene glycol constituents act as solubilizers and solvents, aiding in the dispersion and integration of other formulation components.

This enables it to effectively combine disparate oil and water phases within a formulation, facilitating creamy consistencies and enhancing overall product stability without reported incompatibilities.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-1/PEG-1 STEARAMINE, classified within the PEG propylene glycol derivatives group, is safe for use in cosmetic applications under current practices and concentrations. This assessment was largely based on a 'read-across' methodology, leveraging data from related compounds due to limited specific ingredient data. Notably, previous cautions concerning PEG-containing ingredients on compromised skin have been retracted. While related PEG Stearates have been observed in concentrations typically ranging from >0.1% to 10%, a specific maximum concentration for PPG-1/PEG-1 STEARAMINE has not been provided.
