Nylon-611/Dimethicone Copolymer ●
TL;DR. This ingredient is a synthetic film-forming and texture-modifying polymer. It is used to improve slip, soft-focus appearance, powdery feel, pigment dispersion, and wear in makeup, sunscreen, and skin products.
What does Nylon-611/Dimethicone Copolymer do in a cosmetic formula?
This ingredient is a synthetic film-forming and texture-modifying polymer. It is used to improve slip, soft-focus appearance, powdery feel, pigment dispersion, and wear in makeup, sunscreen, and skin products.
Is Nylon-611/Dimethicone Copolymer clean?
From a clean-beauty perspective, it is usually flagged for being a synthetic silicone-containing polymer rather than for irritation, since skin tolerance is generally good. It can create restricted-list friction in standards that limit persistent synthetic polymers or non-biodegradable particulate materials.
Is Nylon-611/Dimethicone Copolymer sustainable?
This material is made from synthetic petrochemical and mineral-derived feedstocks. It is not readily biodegradable, so the main sustainability concern is environmental persistence, especially in rinse-off or dispersible formats.
Is Nylon-611/Dimethicone Copolymer COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic because synthetic silicone-type polymers are not permitted in those standards. Its Green Chemistry profile is weak due to non-renewable feedstocks and poor biodegradability, even though it can support durable films at low use levels.
How does Nylon-611/Dimethicone Copolymer work chemically?
The molecule is a high-molecular-weight hybrid polymer with flexible organosilicon segments and hydrogen-bonding amide segments, giving it a smooth, elastic film and strong sensory modification. It is typically used as a dispersed solid or gelled polymer phase, often around low single-digit to about 10% levels depending on format, and it is broadly stable across normal cosmetic pH because it is not used as a pH-active material.
