Amodimethicone ●
TL;DR. This ingredient is a hair-conditioning agent and film-former that deposits selectively on damaged, negatively charged hair. It improves slip, wet and dry combing, softness, frizz control, and heat-styling feel.
What does Amodimethicone do in a cosmetic formula?
This ingredient is a hair-conditioning agent and film-former that deposits selectively on damaged, negatively charged hair. It improves slip, wet and dry combing, softness, frizz control, and heat-styling feel.
Is Amodimethicone clean?
From a clean-beauty perspective, this ingredient is usually flagged because many standards limit persistent synthetic conditioning polymers. It has low direct irritation potential in finished formulas, but its clean-standard friction comes from environmental persistence and buildup concerns rather than routine skin sensitization.
Is Amodimethicone sustainable?
This material is synthetically produced from mineral-derived silicon chemistry and petrochemical inputs. It is not readily biodegradable, and larger polymeric residues can persist in wastewater sludge and sediments.
Is Amodimethicone COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards. Its limited biodegradability and synthetic organosilicon backbone make it a weak fit with Green Chemistry priorities around persistence and end-of-life profile.
How does Amodimethicone work chemically?
The molecule is a high-molecular-weight polysiloxane modified with pendant aminoalkyl groups, which become cationic under mildly acidic rinse-off conditions and bind to negatively charged hair keratin. It is commonly supplied as an emulsion and used to deliver about 0.1 to 2% active material, with compatibility best managed through appropriate emulsifiers and charge balance in the formula.
