Cholesteryl Chloride ●
TL;DR. This ingredient is a highly lipophilic skin-conditioning material used to add emollience, water resistance, and lipid-like structure to anhydrous or emulsion systems.
What does Cholesteryl Chloride do in a cosmetic formula?
This ingredient is a highly lipophilic skin-conditioning material used to add emollience, water resistance, and lipid-like structure to anhydrous or emulsion systems.
Is Cholesteryl Chloride clean?
It is a niche halogenated sterol derivative, which creates more clean-standard friction than common skin lipids even though direct irritation flags are not prominent in the cosmetic literature. Restrictive clean frameworks generally favor simpler, readily biodegradable lipid alternatives, and this material is not a typical natural-standard ingredient.
Is Cholesteryl Chloride sustainable?
This material is made by chemically modifying a sterol feedstock that may come from animal, wool-grease, or plant sources depending on the supply chain. Its high hydrophobicity and organochlorine structure mean poor water solubility and limited ready-biodegradability support, so environmental alignment is weaker than for simple plant oils or fatty alcohols.
Is Cholesteryl Chloride COSMOS-approved?
It is not aligned with COSMOS-organic or COSMOS-natural because it is a chemically chlorinated derivative rather than an allowed natural or naturally derived cosmetic ingredient. From a Green Chemistry view, the halogenation step, mixed feedstock sourcing, and uncertain ready biodegradability are the main weaknesses.
How does Cholesteryl Chloride work chemically?
The molecule is a neutral, nonionic chlorinated sterol with one chlorine replacing the usual polar 3-hydroxyl group, giving very high lipophilicity and negligible water solubility. In formulations, pH has little direct effect because it is not ionizable in normal cosmetic ranges, while stability is more tied to oxidation of the unsaturated sterol backbone and compatibility with oils, waxes, and other lipid phases.
