ISOSTEARETH-10 STEARATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Isosteareth-10 Stearate is a synthetic non-ionic emulsifier, crucial for creating stable cosmetic formulations. Its unique molecular structure possesses both oil-attracting (lipophilic) and water-attracting (hydrophilic) segments, enabling it to bridge immiscible phases. This allows for the consistent blending of oil and water in a variety of skincare and cosmetic products.

Summary

Emulsifier

Science

Mechanism of Action

Functioning as an emulsifier, Isosteareth-10 Stearate works by significantly reducing the interfacial tension between otherwise incompatible oil and water components. Its amphiphilic nature allows it to encapsulate dispersed phases within a continuous phase, forming stable emulsions. This mechanism prevents separation, ensuring product integrity and a uniform texture.

Stability

As a polyethylene glycol (PEG) derivative, Isosteareth-10 Stearate's water solubility and hygroscopicity tend to decrease with increasing molar mass. PEG ethers generally exhibit robust stability across a wide pH spectrum, demonstrating resistance to both acidic and alkaline conditions.

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that alkyl PEG ethers, including Isosteareth-10, are safe for use under current practices, provided they are formulated to be non-irritating. The Stearic Acid component is affirmed as Generally Recognized As Safe (GRAS) by the US FDA. However, a critical consideration for PEG derivatives involves potential contamination with trace impurities like ethylene oxide and 1,4-dioxane, requiring strict quality control during manufacturing.
