Lauryl Dimethicone ●
TL;DR. This ingredient is primarily an emollient and conditioning film-former. It adds slip, cushion, water resistance, and a dry, waxy feel to skin, hair, and color cosmetics.
What does Lauryl Dimethicone do in a cosmetic formula?
This ingredient is primarily an emollient and conditioning film-former. It adds slip, cushion, water resistance, and a dry, waxy feel to skin, hair, and color cosmetics.
Is Lauryl Dimethicone clean?
From a clean-beauty perspective, it is generally low-irritation and not a common allergen, but many stricter clean frameworks flag it because it is a non-biodegradable synthetic polymer. It also sits outside most natural-certification programs that exclude this type of chemistry.
Is Lauryl Dimethicone sustainable?
This material is synthetic, commonly based on mineral-derived silicon chemistry combined with petrochemical carbon chains. It is expected to be poorly biodegradable and environmentally persistent compared with plant oils, esters, or fatty alcohols.
Is Lauryl Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because this type of synthetic polymer chemistry is outside the allowed ingredient categories. Its Green Chemistry fit is weak, with limited renewable content, poor biodegradability, and an end-of-life profile that is the main concern despite low reactivity in formulas.
How does Lauryl Dimethicone work chemically?
The molecule is a synthetic polymer built from repeating silicon-oxygen units with methyl groups and long C12 hydrocarbon side chains, which makes it more wax-like and substantive than more fluid related materials. It is anhydrous, broadly pH-insensitive in finished products, oxidation-resistant, and typically used at low single-digit levels to improve glide, payoff, water resistance, and pigment dispersion compatibility.
