AMMONIUM ETHYLENE/MA COPOLYMER

Description

Ammonium Ethylene/MA Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This ingredient is primarily employed as a film-forming agent and emulsion stabilizer. Its unique structure, composed of ammonium ethylene and maleic anhydride (MA) units, provides excellent adhesion properties and helps create a smooth, even application of products on the skin.

In skincare formulations, Ammonium Ethylene/MA Copolymer contributes to the longevity and durability of products such as sunscreens, foundations, and moisturizers. It forms a protective barrier on the skin, enhancing the product's resistance to water and sweat. This characteristic is particularly beneficial in long-wearing makeup and sun protection products.

The copolymer also aids in improving the texture and consistency of formulations, resulting in a more pleasant user experience. Its ability to stabilize emulsions helps prevent separation of oil and water phases in products, ensuring a uniform distribution of active ingredients.

While generally considered safe for use in cosmetics, individuals with sensitive skin should perform patch tests before incorporating products containing this ingredient into their routine. As with any synthetic polymer, potential allergic reactions or irritations may occur in rare cases.
