Glycine Soja Sterols

Glycine Soja (soybean) sterols are lipid-phase barrier-supporting emollients used at low percentages in creams/lotions, and they are generally well tolerated with minimal inherent irritancy. The main safety concern is uncommon delayed sensitization in individuals with soy-related contact allergy, but in routine use concentrations they are typically suitable for sensitive and compromised skin. Safety Notes: In commercial skincare, Glycine Soja (Soybean) Sterols are most often used as a minor fraction of lipid/lamellar/emulsifier blends in leave-on creams/lotions, where they commonly appear around 0.01–0.3% to support barrier and texture. Higher-strength consumer products (e.g., barrier-repair balms, anhydrous lipid concentrates, and lamellar-structured moisturizers using phytosterol-rich complexes) can reach ~1–5% active sterols, with ~5% representing the upper end seen OTC due to cost, solubility/processing limits, and risk of waxy feel; rinse-off products typically sit at the low end because contact time and deposition are limited.
