Dimethicone 1% ●
TL;DR. At 1%, this ingredient primarily acts as a conditioning agent and sensory modifier, adding slip, reducing tackiness, and forming a light protective film on skin or hair.
What does Dimethicone 1% do in a cosmetic formula?
At 1%, this ingredient primarily acts as a conditioning agent and sensory modifier, adding slip, reducing tackiness, and forming a light protective film on skin or hair.
Is Dimethicone 1% clean?
It is generally low-irritation and well tolerated, but many clean-beauty frameworks flag or restrict it because it is a synthetic, non-biodegradable film-former. The main concern is environmental persistence rather than direct skin compatibility.
Is Dimethicone 1% sustainable?
This material is synthetically produced from mineral-derived silicon chemistry and is not readily biodegradable. It can persist in aquatic and sediment environments, which gives it a weaker sustainability profile than readily biodegradable plant-derived emollients.
Is Dimethicone 1% COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry perspective, it scores poorly on biodegradability and renewable feedstock alignment, even though it is chemically stable and typically used at low levels.
How does Dimethicone 1% work chemically?
The molecule is a high-molecular-weight linear polymer with repeating Si-O units and methyl side groups, which gives it low surface tension, strong spreadability, and a non-water-soluble film. At around 1%, it is used for slip and conditioning, remains stable across typical cosmetic pH ranges, and usually needs appropriate emulsifiers or dispersing systems in water-based formulas.
