Glycerol Stearate ●
TL;DR. This ingredient is primarily an emulsifier and consistency builder, helping oil and water phases stay blended while adding creaminess and body to lotions, creams, and conditioners.
What does Glycerol Stearate do in a cosmetic formula?
This ingredient is primarily an emulsifier and consistency builder, helping oil and water phases stay blended while adding creaminess and body to lotions, creams, and conditioners.
Is Glycerol Stearate clean?
It is generally well tolerated, low in irritation potential, and not a common allergen. Clean-beauty standards usually view it as low-friction when it is made from acceptable feedstocks and without concerning residual impurities.
Is Glycerol Stearate sustainable?
This material is commonly made from vegetable fatty feedstocks, though palm sourcing can be a supply-chain consideration. It is expected to be readily biodegradable and does not raise major persistence concerns.
Is Glycerol Stearate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when produced from allowed raw materials and approved processing routes. From a Green Chemistry lens, it aligns well when sourced from renewable oils and made through simple esterification with minimal solvent burden.
How does Glycerol Stearate work chemically?
The molecule is an amphiphilic fatty ester, with one oil-loving chain and multiple oxygen-containing groups that help it sit at the oil-water interface. Typical use levels are about 1% to 5%, and it is usually melted into the oil phase around 55°C to 70°C, with best stability away from strongly acidic or strongly alkaline conditions.
