TL;DR. This ingredient is a waxy structuring agent that thickens creams, lotions, conditioners, and balms. It also helps stabilize emulsions and gives formulas a smoother, more cushiony skin feel.
What does Stearyl Alcohol do in a cosmetic formula?
This ingredient is a waxy structuring agent that thickens creams, lotions, conditioners, and balms. It also helps stabilize emulsions and gives formulas a smoother, more cushiony skin feel.
Is Stearyl Alcohol clean?
It is widely accepted in clean-beauty frameworks, with low irritation potential and no common restricted-list concerns. Unlike short-chain volatile solvents, it is nonvolatile, waxy, and conditioning rather than drying.
Is Stearyl Alcohol sustainable?
This material is typically derived from vegetable oils, often palm or coconut, though petroleum-based grades also exist. It is readily biodegradable, with the main sustainability question being whether the feedstock is certified and traceable.
Is Stearyl Alcohol COSMOS-approved?
Natural-origin grades are permitted under COSMOS-natural and COSMOS-organic standards, while petrochemical grades would not fit those ingredient rules. Its Green Chemistry profile is strongest when it comes from renewable oils and is made through straightforward hydrogenation with good biodegradability.
How does Stearyl Alcohol work chemically?
The molecule is a saturated C18 long-chain fatty alcohol, solid at room temperature and useful for building lamellar gel networks with emulsifiers. It is commonly used around 0.5% to 5% in emulsions and hair conditioners, is stable across typical cosmetic pH ranges, and is not prone to rancidity like unsaturated lipids.
