Stearoxy Dimethicone ●
TL;DR. This ingredient is a conditioning agent and film-forming emollient used to add slip, gloss, water resistance, and a smoother feel in hair care, skin care, and color cosmetics.
What does Stearoxy Dimethicone do in a cosmetic formula?
This ingredient is a conditioning agent and film-forming emollient used to add slip, gloss, water resistance, and a smoother feel in hair care, skin care, and color cosmetics.
Is Stearoxy Dimethicone clean?
From a clean-beauty perspective, this material has friction because many standards restrict or exclude non-biodegradable synthetic silicone polymers. It is generally low in direct irritation potential, but its clean-standard issue is environmental persistence rather than skin compatibility.
Is Stearoxy Dimethicone sustainable?
This material is synthetically produced from mineral and petrochemical inputs, and it is not readily biodegradable. Its persistence in wastewater and sediments is the main sustainability concern.
Is Stearoxy Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because synthetic silicone polymers are outside the standard’s allowed ingredient categories. Its Green Chemistry alignment is weak due to low biodegradability, non-renewable feedstocks, and specialized organosilicon processing.
How does Stearoxy Dimethicone work chemically?
The molecule has a flexible silicon-oxygen polymer backbone modified with long C18 alkoxy groups, giving it high hydrophobicity, lubrication, and film-forming behavior. It is typically used at low single-digit percentages, is stable across normal cosmetic pH ranges, and usually needs oil-phase solubilization or surfactant-assisted dispersion.
