Dimethicone ●
TL;DR. This ingredient is a silicone-based conditioning agent and film-former that gives slip, gloss, frizz control, and a smooth skin feel. It also helps reduce transepidermal water loss by forming a breathable hydrophobic film.

Is Dimethicone clean?
From a clean-beauty perspective, it is usually well tolerated on skin and has low irritation potential. The main friction is standards-based, since many clean frameworks restrict non-biodegradable silicone materials because of environmental persistence rather than direct skin concerns.
Is Dimethicone sustainable?
This material is synthetic and typically derived from mineral and petrochemical feedstocks. It is not readily biodegradable and can persist in wastewater sludge and sediments, although higher-molecular-weight grades have low water solubility and limited bioavailability.
Is Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its fit with Green Chemistry is weak because it relies on non-renewable feedstocks and has poor biodegradability, despite being chemically stable and effective at low use levels.
How does Dimethicone work chemically?
The molecule is a linear silicon-oxygen polymer with methyl side groups, making it hydrophobic, flexible, and very low in reactivity. Typical use ranges are about 0.5% to 5% in skin and hair products, with higher levels possible in anhydrous formats, and it is broadly stable across cosmetic pH ranges but requires suitable emulsifiers or dispersing systems in water-based formulas.
