C30-45 Alkyl Dimethicone ●
TL;DR. This ingredient is primarily an emollient and film-forming conditioning agent, adding slip, softness, water resistance, and a waxy cushion to skin, hair, and color cosmetics.
What does C30-45 Alkyl Dimethicone do in a cosmetic formula?
This ingredient is primarily an emollient and film-forming conditioning agent, adding slip, softness, water resistance, and a waxy cushion to skin, hair, and color cosmetics.
Is C30-45 Alkyl Dimethicone clean?
It is generally low-irritation and not a common allergen, but it has clean-standard friction because many frameworks limit persistent synthetic organosilicon materials. The concern is less about direct skin tolerance and more about environmental persistence and non-renewable processing.
Is C30-45 Alkyl Dimethicone sustainable?
This material is typically made from mineral-derived and petrochemical or oleochemical feedstocks through synthetic processing. It is not readily biodegradable, and its high molecular weight and low water solubility reduce mobility but do not make it a strong sustainability fit.
Is C30-45 Alkyl Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry lens, it scores poorly on biodegradability, renewable sourcing, and end-of-life profile, even though it is stable and used at low levels.
How does C30-45 Alkyl Dimethicone work chemically?
The molecule is a high-molecular-weight organosilicon polymer modified with long hydrocarbon side chains, which gives it a waxy feel, strong film formation, and good compatibility with oils and anhydrous systems. It is usually used at low single-digit levels, is stable across normal cosmetic pH ranges because it is not water-soluble, and can improve payoff, gloss, and water resistance in sticks, balms, hair conditioners, and makeup.
