PEG-10 PHYTOSTEROL.

Valuable / SURFACTANT - EMULSIFYING

PEG-10 Phytosterol is a synthesized hybrid of hydrophilic PEG-10 and lipophilic natural plant sterols, primarily sourced from rapeseed or soy. It acts as a multifunctional ingredient, effectively emulsifying and conditioning the skin while enhancing overall product texture and stability.

Science

Mechanism of Action

This ingredient's mechanism relies on its amphiphilic nature, where the PEG component is hydrophilic and the phytosterol component is lipophilic, enabling the efficient blending of oil and water phases to form stable emulsions. On the skin, the phytosterol fraction contributes to dermal restoration, improving skin pliability and suppleness, particularly beneficial for aging skin. These sterols also offer moisturizing properties, assist in wound healing, and can stimulate collagen and elastin synthesis by influencing fibroblast growth factors. Furthermore, they demonstrate photoprotective capabilities, aiding in the attenuation of photoaging processes.

Stability

Functions as a stabilizer, bolstering product stability during shelf life and usage, particularly under fluctuating temperatures or moist conditions. It actively helps prevent decomposition often initiated by atmospheric oxygen. This ingredient is known for its ability to form glossy, low-viscosity emulsions and can facilitate the creation of liquid crystal structures.

Safety Profile

CIR Status

2.6%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2004 that PEGs Soy Sterol (including PEG-10 Soy Sterol, an alternate name) are safe for use in cosmetic products. However, it is explicitly recommended to avoid application on damaged or compromised skin due to documented systemic toxicity and sensitization risks associated with PEGs under such conditions. While ethoxylated compounds like PEGs can produce 1,4-dioxane as a byproduct, the industry typically employs purification steps to remove this impurity.
