Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol ●
TL;DR. This ingredient is a nonionic emulsifier, co-emulsifier, and consistency builder for creams and lotions. It helps stabilize oil-in-water emulsions, adds body, and gives a cushioned, less watery skin feel.
What does Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol do in a cosmetic formula?
This ingredient is a nonionic emulsifier, co-emulsifier, and consistency builder for creams and lotions. It helps stabilize oil-in-water emulsions, adds body, and gives a cushioned, less watery skin feel.
Is Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol clean?
From a clean-beauty perspective, this ingredient is generally well tolerated, low in sensitization concern, and not a common restricted-list issue. The main quality considerations are traceable fatty feedstocks and good manufacturing control, rather than an inherent safety controversy.
Is Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol sustainable?
This material is usually made from vegetable-derived fatty feedstocks and glycerin-based chemistry, though palm-derived inputs are common unless specified otherwise. It is expected to be readily biodegradable, with the main sustainability question being feedstock certification and supply-chain traceability.
Is Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when made from approved natural-origin feedstocks and allowed processing routes. Its Green Chemistry profile is favorable because it can use renewable lipid inputs, relies on esterification chemistry, and has good biodegradability.
How does Polyglyceryl-2 Stearate Glyceryl Stearate Stearyl Alcohol work chemically?
Chemically, this material combines polyglycerol fatty-acid esters, simple glycerol fatty-acid esters, and a long-chain saturated fatty alcohol, creating a lamellar, waxy emulsifying system. Typical use is about 2 to 8% in the heated oil phase, and it is stable across normal cosmetic pH ranges, with ester hydrolysis becoming more relevant under strongly acidic or alkaline conditions.
