Sorbitan Isostearate ●
TL;DR. This ingredient is a nonionic emulsifier and co-emulsifier, especially useful for water-in-oil systems and richer creams. It helps disperse pigments and oils while improving texture and emulsion stability.
What does Sorbitan Isostearate do in a cosmetic formula?
This ingredient is a nonionic emulsifier and co-emulsifier, especially useful for water-in-oil systems and richer creams. It helps disperse pigments and oils while improving texture and emulsion stability.
Is Sorbitan Isostearate clean?
It is generally well tolerated, with low sensitization concern and little clean-standard friction when made from acceptable feedstocks. Clean frameworks mainly look at feedstock origin, residual processing materials, and overall formula context rather than flagging the molecule itself.
Is Sorbitan Isostearate sustainable?
This material is commonly made from plant-derived fatty acids and sugar-alcohol-based feedstocks, though certification depends on traceability and any palm-linked supply chain controls. It is expected to be biodegradable and is not known for environmental persistence concerns.
Is Sorbitan Isostearate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from approved natural-origin feedstocks and compliant processing. Its Green Chemistry fit is good because it is a non-ethoxylated ester, can use renewable inputs, and has a favorable biodegradability profile.
How does Sorbitan Isostearate work chemically?
The molecule is a nonionic fatty acid ester with a sugar-alcohol-derived polar head and a branched C18 lipophilic tail, giving it a low HLB around 4 to 5. Typical use is often about 0.5% to 5% depending on whether it is acting as a co-emulsifier, pigment dispersant, or primary water-in-oil structuring aid, and ester bonds are most stable away from strong acid or alkaline conditions.
