HYDROXYBUTYL METHYLCELLULOSE

Description

Hydroxybutyl methylcellulose (HBMC) is a semi-synthetic polymer derived from cellulose, widely used in skincare and cosmetic formulations. This versatile ingredient functions as a thickening agent, emulsifier, and film-former, contributing to improved texture and stability in various products.

HBMC exhibits excellent water retention properties, making it an effective humectant that helps maintain skin hydration. Its ability to form a thin, flexible film on the skin's surface aids in reducing transepidermal water loss and protecting against environmental stressors. This film-forming quality also enhances the spreadability and feel of skincare products, promoting a smooth application.

As a non-ionic polymer, HBMC is compatible with a wide range of active ingredients and formulation types, including both oil-in-water and water-in-oil emulsions. It demonstrates stability across a broad pH range and is resistant to electrolytes, making it suitable for diverse skincare formulations.

HBMC is generally well-tolerated by most skin types and is considered non-irritating and non-sensitizing. Its low potential for allergic reactions makes it a favorable choice for formulating products intended for sensitive skin. Additionally, HBMC can contribute to the controlled release of active ingredients, potentially enhancing their efficacy and longevity on the skin.
