Sorbitan sesquioleate is a mixture of mono and diesters
of oleic acid and extol anhydrides derived from sorbitol.
It is used as a surfactant and an emulsifier in cosmetics.
It acts sometimes as a contact allergen,
particularly in leg ulcer patients. It is also responsible
for false-positive patch test reactions to haptens, with
which some allergen providers emulgated, such as
parabens mix, fragrance mix, Amerchol L101, and
ethylene-urea /melamine formaldehyde. | [InChIKey]

Liquid | [Uses]
Lonzest(R) SOC is a low HLB, w/o emulsifier suggested for use in cosmetic formulations and household products. Also used in emulsifying explosives. | [Definition]
Sorbitan sesquioleate (SSO) is a water-in-oil emulsifier that allows oil and water to blend into a homogeneous mixture that does not separate. It is widely used in cosmetics such as moisturizers, cleansers, conditioners, eye makeup removers, exfoliating products, sunscreens, and baby products. Closely related emulsifiers such as Span 20 (sorbitan monolaurate), Span 40 (sorbitan monopalmitate), span 60 (sorbitan monostearate), span 65 (sorbitan tristearate), span 80 (sorbitan monooleate), and Span 85 (sorbitan trioleate) can cross-react with SSO. They, therefore, should be avoided in patients sensitive to SSO. | [Brand name]
Arlacel 83 (ICI Americas); Arlacel C (ICI Americas). | [Flammability and Explosibility]
Nonflammable | [Biological Activity]
Sorbitan sesquioleate is useful as a stabilizing agent in polymerization process to produce spherical acrylamide beads. It has been used in many topical agents. SSO have recently been implicated in allergic dermatitis. | [Safety]
Sorbitan Sesquioleate is considered a low hazard ingredient by the Cosmetics Database, which only notes mild concerns regarding organ system and toxicity, due to animal studies that showed organ effects and skin moderation at moderate doses. |
