SORBITAN SESQUIOLEATE ●
TL;DR. This ingredient is a low-HLB nonionic emulsifier used mainly to stabilize water-in-oil emulsions. It also helps disperse pigments and oils in creams, balms, makeup, and cleansing products.
What does SORBITAN SESQUIOLEATE do in a cosmetic formula?
This ingredient is a low-HLB nonionic emulsifier used mainly to stabilize water-in-oil emulsions. It also helps disperse pigments and oils in creams, balms, makeup, and cleansing products.
Is SORBITAN SESQUIOLEATE clean?
From a clean-beauty perspective, this ingredient is generally well accepted and has low irritation potential for most users. The main quality considerations are feedstock traceability and residual processing impurities, not a major restricted-list profile.
Is SORBITAN SESQUIOLEATE sustainable?
This material is typically made from plant-derived fatty feedstocks and a sugar-derived alcohol, although the oil source can vary by supplier. It is expected to be biodegradable and is not known for environmental persistence, with palm-linked sourcing as the main supply-chain point to check.
Is SORBITAN SESQUIOLEATE COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from compliant natural feedstocks and approved esterification chemistry. Its profile fits Green Chemistry reasonably well because it can use renewable inputs, mild processing, and biodegradable ester chemistry.
How does SORBITAN SESQUIOLEATE work chemically?
The molecule is a low-HLB, nonionic mixture of partial esters built from a dehydrated sugar alcohol and a C18 monounsaturated fatty acid, so it preferentially stabilizes water-in-oil systems. Typical use is about 0.5 to 5% as a co-emulsifier, often paired with higher-HLB emulsifiers, and it is stable across common cosmetic pH because it does not rely on ionization.
