PEG-80 Sorbitan Laurate

PEG-80 Sorbitan Laurate is a nonionic surfactant/solubilizer used in cleansers and emulsions (often ~0.1–5%) that can disrupt the stratum corneum lipids and increase barrier permeability, especially when combined with other surfactants. Clinical patch-test data for PEG sorbitan esters generally show low but measurable irritation and rare sensitization, with risk rising on compromised skin (eczema, post-procedure) and with leave-on exposure. Given its surfactant nature and cumulative routine effects, I rate it as mild with occasional sensitivity possible in reactive individuals. Safety Notes: PEG-80 Sorbitan Laurate is used primarily as a nonionic surfactant/solubilizer and emulsifier; in many leave-on lotions/serums and facial products it appears at very low levels (~0.05–0.5%) to aid fragrance/oil solubilization or stabilize emulsions. In rinse-off cleansers, micellar waters, and makeup removers it is commonly higher (about 1–5%), and consumer-available high-surfactant cleansing concentrates and oil-to-milk removers can reach roughly 8–10% as part of the total surfactant system. There is no specific EU/FDA maximum for this INCI, so observed use is mainly constrained by irritation potential, clarity/viscosity targets, and emulsion/surfactant system balance.
