Sorbitan Oleate Decylglucoside Crosspolymer

Sorbitan Oleate Decylglucoside Crosspolymer is a polymeric non-ionic surfactant/emulsifying and solubilizing agent typically used at low levels (often <1–3%) to stabilize formulas and improve sensorial properties. Decyl glucoside–based materials can still provoke stinging or barrier disruption in a subset of highly reactive or eczematous patients (especially in leave-on products or when combined with other surfactants), but crosspolymerization generally reduces free surfactant activity and lowers irritation risk compared with simple surfactants. Overall it is usually well tolerated, yet not inert, so I score it as gentle with a small but real irritation potential in compromised skin. Safety Notes: Sorbitan Oleate Decylglucoside Crosspolymer is a polymeric emulsifier/rheology modifier typically used at low levels to stabilize O/W emulsions and improve sensory/viscosity; in mainstream leave-on lotions/creams it is commonly seen around ~0.1–1%. The lowest market-observed use levels (~0.05%) occur where it is a secondary stabilizer in multi-emulsifier systems, while higher-strength consumer-available products (notably anhydrous-to-aqueous transforming balms/gel-creams, high-oil-load cleansers, and specialty texture systems) can use it up to about ~5% to build structure and stabilize challenging phases. No specific FDA/EU maximum applies for this ingredient as such; practical upper limits are driven by texture, potential soaping/tack, and compatibility with oils/surfactants, with rinse-off formats generally tolerating the upper end more readily than leave-on.
