Polyethylene
Ingredient Info
Polyethylene is a synthetic plastic polymer used in skincare products as a thickening agent, emollient, and texture modifier. It creates a smooth, spreadable consistency and helps bind ingredients together in formulations.
Benefits
- Creates smooth, pleasant texture in creams and lotions
- Helps stabilize and thicken product formulations
- Provides a protective barrier on skin surface
Potential concerns
- Poor biodegradability — persists in the environment and may accumulate over time
- Not derived from renewable sources, contributing to plastic waste
- Microplastic concern if used in products that wash down drains
Science: Research indicates polyethylene shows poor environmental biodegradability and does not meet emerging sustainability criteria for topical skincare products. While safe for skin contact, dermatological literature increasingly recommends plant-based alternatives (such as plant waxes and biopolymers) to reduce environmental impact.
