PEG-2 SOYAMINE.

Valuable CAS 61791-24-0 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-2 Soyamine is a versatile, soy-derived ingredient primarily employed as a surfactant and emulsifier in cosmetic formulations. It facilitates the stable blending of immiscible liquids and contributes to effective cleansing and potential skin moisture retention.

Summary

Surfactant Emulsifying Anti-irritant Neutralizing Anti-static Foam Booster Mild Detergent Moisture Retention

Science

Mechanism of Action

As a surfactant, PEG-2 Soyamine effectively lowers the surface tension of liquids, which enhances its cleansing action for skin and hair. Its emulsifying properties are critical for creating and stabilizing homogeneous mixtures of ingredients like oil and water within cosmetic products. Additionally, as a polyethylene glycol (PEG) derivative, it has the capacity to form hydrogen bonds with water molecules, thereby supporting moisture retention in the skin and potentially mitigating water evaporation.

The Cosmetic Ingredient Review (CIR) Expert Panel initially deemed data insufficient in 1999. However, an amended safety assessment in 2015 concluded that PEG-2 Soyamine and related ingredients are safe for cosmetic use when formulated to be non-irritating. The highest reported maximum concentration for a related ingredient, PEG-5 Soyamine, is 4% in hair coloring formulations, a context where PEG-2 Soyamine is also frequently utilized, particularly in rinse-off products. Concerns regarding potential contamination with residual ethylene oxide and 1,4-dioxane have been noted.
