POLYESTER-18

Description

Polyester-18 is a synthetic polymer utilized in various cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and emulsion stabilizer. Its molecular structure consists of repeating ester units, providing unique properties that benefit skincare and makeup products.

In skincare applications, Polyester-18 creates a lightweight, breathable film on the skin's surface, helping to lock in moisture and protect against environmental stressors. This film-forming ability also contributes to the long-wearing properties of cosmetic products, particularly in foundations and concealers.

As an emulsion stabilizer, Polyester-18 aids in maintaining the stability and consistency of products containing both oil and water phases. This property is especially valuable in formulations such as lotions, creams, and liquid foundations, ensuring a smooth, homogeneous texture throughout the product's shelf life.

Polyester-18 is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations. Its low molecular weight allows for easy incorporation into various product bases without significantly altering their texture or feel on the skin.
