Dimethiconol Stearate ●
TL;DR. This ingredient functions as an emollient, conditioning agent, and film-former, adding slip, gloss, cushion, and water resistance in skin, hair, and color products.
What does Dimethiconol Stearate do in a cosmetic formula?
This ingredient functions as an emollient, conditioning agent, and film-former, adding slip, gloss, cushion, and water resistance in skin, hair, and color products.
Is Dimethiconol Stearate clean?
From a clean-beauty perspective, this ingredient often faces restricted-list friction because it is a nonvolatile silicone derivative with low biodegradability rather than because of high irritation. It is generally well tolerated on skin, but many frameworks prefer readily biodegradable conditioning agents.
Is Dimethiconol Stearate sustainable?
This material is synthetically made from silicon-based chemistry, with the fatty acid portion commonly sourced from plant or animal fats. The silicone backbone is not readily biodegradable and can persist in aquatic and sediment compartments, which weakens its environmental profile.
Is Dimethiconol Stearate COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic formulations because synthetic silicone derivatives fall outside the allowed chemistry. Its persistence and low biodegradability are weak fits with Green Chemistry, even when it delivers performance at low use levels.
How does Dimethiconol Stearate work chemically?
The molecule is a it-functionalized silicone polymer, combining a flexible siloxane backbone with a long C18 fatty chain that increases waxy slip and film formation. It is used mainly in anhydrous sticks, creams, hair products, and color cosmetics, where it improves payoff, water resistance, gloss, and cushion.
