Sorbitan Stearate

Sorbitan Stearate is a non-ionic emulsifier used typically around 0.5–5% in creams and lotions and is generally well tolerated, including in products intended for sensitive skin. Human patch testing and clinical use suggest a low rate of irritation and sensitization compared with many surfactants, though rare reactions can occur in highly reactive or eczema-prone patients, especially on compromised skin. Safety Notes: Sorbitan stearate is widely used as a nonionic emulsifier/co-emulsifier and structurant, and in commercial leave-on creams/lotions it often appears at low levels (~0.05–1%) to support emulsion stability alongside other emulsifiers. Higher levels (3–10%) are observed in consumer-available anhydrous cleansing balms, cold-cream type makeup removers, and high-oil W/O or hybrid systems where it also contributes body and pigment wetting; rinse-off products typically sit in the low-to-mid part of the range due to feel and rinsability constraints. There is no specific EU/FDA maximum for sorbitan stearate in cosmetics, so practical stability/sensory limits largely define the upper end in OTC products.
