Thirsty: Dimethicone ●
TL;DR. This ingredient is a non-volatile conditioning and film-forming polymer used to add slip, reduce tack, improve spread, and create a smooth protective feel on skin or hair.
What does Thirsty: Dimethicone do in a cosmetic formula?
This ingredient is a non-volatile conditioning and film-forming polymer used to add slip, reduce tack, improve spread, and create a smooth protective feel on skin or hair.
Is Thirsty: Dimethicone clean?
From a clean-beauty perspective, it is generally low-irritation and non-sensitizing, but it has significant restricted-list friction because many standards do not accept persistent synthetic polymers.
Is Thirsty: Dimethicone sustainable?
This material is made from mineral silicon inputs plus fossil-derived methyl chemistry in conventional supply chains. It is not readily biodegradable and can persist through wastewater treatment, with residues partitioning into sludge and sediments.
Is Thirsty: Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its profile is weak against Green Chemistry preferences because it relies on non-renewable inputs and shows limited biodegradability despite good user safety.
How does Thirsty: Dimethicone work chemically?
The molecule is a methyl-substituted silicon-oxygen polymer whose performance depends on chain length and viscosity, from light fluids to heavier film formers. Typical use is about 0.5 to 5% in skin care and 1 to 10% in hair care, and it is highly pH-stable, oxidation-resistant, hydrophobic, and usually needs emulsifiers or pre-dispersed formats for water-based formulas.
