SORBIDAN ISOSTEARATE ●
TL;DR. This ingredient is a nonionic, oil-soluble emulsifier used mainly to build water-in-oil emulsions and help disperse pigments, powders, and oils. It also supports texture and mild skin-conditioning in creams, balms, makeup, and sunscreens.
What does SORBIDAN ISOSTEARATE do in a cosmetic formula?
This ingredient is a nonionic, oil-soluble emulsifier used mainly to build water-in-oil emulsions and help disperse pigments, powders, and oils. It also supports texture and mild skin-conditioning in creams, balms, makeup, and sunscreens.
Is SORBIDAN ISOSTEARATE clean?
From a clean-beauty perspective, this ingredient is generally well tolerated and has little restricted-list friction. Sensitivity is uncommon, although any emulsifier can feel heavy or occlusive in formulas designed for very acne-prone skin.
Is SORBIDAN ISOSTEARATE sustainable?
This material is commonly made from sugar-derived and fatty-acid-derived feedstocks, often plant-origin depending on supplier sourcing. It is expected to biodegrade more readily than silicone or fluorinated film-formers, with the main sustainability question being traceability of the fatty-acid supply chain.
Is SORBIDAN ISOSTEARATE COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when the feedstocks and processing route meet the standard’s rules for chemically processed agro-ingredients. Its fit with Green Chemistry is favorable when plant-derived inputs, esterification chemistry, and readily biodegradable design are used.
How does SORBIDAN ISOSTEARATE work chemically?
The molecule is a low-HLB nonionic ester built from a dehydrated sugar alcohol core and a branched C18 fatty acid chain, which gives it strong oil affinity and water-in-oil emulsifying behavior. Typical use is about 0.5% to 5% as a co-emulsifier or dispersant, and it is broadly stable across normal cosmetic pH ranges because it sits in the oil phase rather than relying on ionic charge.
