PEG-10 RAPESEED STEROL

What Is PEG-10 RAPESEED STEROL?

A PEG-10 ether of rapeseed-derived phytosterols. The longer PEG chain compared to PEG-5 Rapeseed Sterol provides greater water solubility and improved emulsifying properties while still delivering the barrier-supporting and skin-conditioning benefits of plant sterols. It helps stabilize formulations and contributes to skin barrier health.

Key Skin Benefits

• + Enhanced water solubility — higher PEG content means better dispersion in aqueous products
• + Barrier repair — delivers plant sterols that support the skin's lipid barrier
• + Mild emulsification — helps stabilize oil-in-water systems while conditioning

Pros

• + Plant-derived — rapeseed phytosterols are a renewable resource
• + Cholesterol-analog structure — complements skin's natural barrier lipids
• + CIR-reviewed — safe for cosmetic use
• + Non-comedogenic
• + Dual-function — emulsifies while conditioning, reducing need for separate ingredients

Cons

• − PEG content — ethoxylation and 1,4-dioxane concerns
• − Higher PEG ratio means less active sterol per gram
• − Limited specific clinical data beyond class-level safety review
