HYDROXYPROPYL METHYLCELLULOSE

Description

Hydroxypropyl methylcellulose (HPMC) is a versatile, semi-synthetic polymer derived from cellulose. It functions as a thickening agent, emulsifier, and stabilizer in various skincare and cosmetic formulations. HPMC forms a clear, non-greasy film on the skin, providing a smooth texture and enhancing the spreadability of products.

In skincare, HPMC acts as a humectant, attracting and retaining moisture to help maintain skin hydration. Its film-forming properties create a protective barrier that reduces transepidermal water loss and shields the skin from environmental stressors. HPMC is particularly beneficial in oil-free formulations, as it can impart a silky feel without adding oils.

This ingredient is well-tolerated by most skin types and is considered non-irritating and non-comedogenic. It's commonly used in serums, gels, and lightweight moisturizers. HPMC also enhances the stability of active ingredients in formulations, potentially improving their efficacy.

From a formulation standpoint, HPMC offers excellent compatibility with a wide range of ingredients and maintains its viscosity across various pH levels. It's resistant to microbial growth, contributing to the preservation of skincare products.
