Glycine Max Oil

Glycine Max Oil (soybean oil) is primarily an emollient/occlusive lipid typically used at moderate-to-high concentrations and is generally well tolerated, with low irritancy in patch testing compared with fragrances or active acids. However, as a plant-derived oil it can still trigger irritation or dermatitis in a minority of highly reactive or eczema-prone patients (including those with lipid intolerance or allergy), so it is not scored as exceptionally gentle for compromised skin. Safety Notes: In commercial skincare, Glycine Max (Soybean) Oil is often used as a minor emollient/solubilizing lipid in leave-on serums, lotions, and cleansers at very low levels (~0.05–1%). It commonly appears at mid-levels (~2–20%) in creams, body lotions, cleansing balms, and makeup removers, while high-strength consumer products like facial/body oils and massage oils can be predominantly soybean oil, including single-ingredient oils sold to consumers at 100%. No specific EU/FDA maximum is set for soybean oil in cosmetics; practical limits are driven by sensory feel, oxidation stability, and product format (leave-on oils can reach the highest levels).
