Ethylene/Propylene Copolymer

Ethylene/propylene copolymer is a synthetic plastic material made by linking ethylene and propylene molecules together. It forms small, solid particles that are incorporated into skincare products, particularly cleansers and scrubs.In formulations, it functions as a mechanical exfoliant—the particles work to physically remove dead skin cells and surface debris when you massage the product onto skin. It also acts as a bulking agent and film-forming ingredient, helping to give products their texture and consistency.

When you apply a product containing this copolymer and massage it across your skin, the small plastic particles create friction. This mechanical action loosens and removes the outermost layer of dead skin cells, which is the principle behind physical exfoliation.Unlike chemical exfoliants that dissolve dead skin through enzymes or acids, this ingredient achieves exfoliation purely through the physical action of the particles against the skin's surface.

Use gentle, circular motions when applying scrubs containing this ingredient—avoid pressing hard or over-scrubbing, as this can cause irritation. Limit use to 1-3 times per week depending on your skin's tolerance. Always follow with a hydrating moisturiser and sunscreen during the day.

This ingredient is generally considered safe for topical use in cosmetics. However, avoid use on broken or very sensitive skin, and rinse thoroughly after application to ensure no particles remain on the skin.
