ETHYL METHACRYLATE COPYOLYMER ●
TL;DR. This ingredient is primarily a film-former and binder, helping color cosmetics, nail products, and styling formulas form a flexible, adherent coating. It can improve wear, gloss, water resistance, and pigment hold.
What does ETHYL METHACRYLATE COPYOLYMER do in a cosmetic formula?
This ingredient is primarily a film-former and binder, helping color cosmetics, nail products, and styling formulas form a flexible, adherent coating. It can improve wear, gloss, water resistance, and pigment hold.
Is ETHYL METHACRYLATE COPYOLYMER clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic persistent polymer rather than a simple biodegradable material. The main considerations are residual monomer control, inhalation exposure in sprays or powders, and retailer restrictions on intentionally added microplastic-type polymers.
Is ETHYL METHACRYLATE COPYOLYMER sustainable?
This material is typically petrochemical-derived and is not considered readily biodegradable. Its durability is useful in formulas, but that same persistence creates environmental concern when it enters wastewater or is shed as small polymer fragments.
Is ETHYL METHACRYLATE COPYOLYMER COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic standards because it is a non-natural synthetic polymer made by addition polymerization. Its Green Chemistry alignment is limited, since it is not renewable, not readily biodegradable, and depends on conventional synthetic processing.
How does ETHYL METHACRYLATE COPYOLYMER work chemically?
The molecule is a high-molecular-weight ester-based addition polymer with a hydrophobic carbon backbone and pendant ester groups, which gives cohesive film formation and resistance to water. It is commonly used at low to moderate levels, often around 1 to 10% in color cosmetics and styling products, with higher levels possible in nail coatings depending on the desired film strength.
