POLYBUTENE

Description

Polybutene is a synthetic liquid polymer derived from isobutylene, widely used in cosmetic and skincare formulations. This versatile ingredient functions primarily as an emollient, thickening agent, and film-former. Its molecular structure consists of repeating butene units, resulting in a clear, colorless, and odorless substance with a viscous consistency.

In skincare products, polybutene imparts a smooth, silky texture and helps to create a protective barrier on the skin's surface. This barrier aids in reducing transepidermal water loss, thus promoting hydration and softness. The ingredient's film-forming properties contribute to the long-lasting effects of makeup and other leave-on products.

Polybutene is particularly valued for its ability to enhance product spreadability and provide a non-greasy feel. It is commonly incorporated into lip products, such as lipsticks and glosses, where it imparts shine and improves wear time. Additionally, polybutene can act as a plasticizer, increasing the flexibility of formulations and preventing product cracking or drying out.

While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before widespread application. Polybutene is non-comedogenic and suitable for various skin types, making it a popular choice in diverse skincare and cosmetic formulations.
