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 product spreadability.

In skincare, HPMC acts as a humectant, attracting and retaining moisture to help keep the skin hydrated. Its film-forming properties create a protective barrier that can reduce transepidermal water loss. This ingredient is particularly beneficial in products designed for sensitive or dry skin types.

HPMC is non-ionic, making it compatible with a wide range of active ingredients and preservatives. It maintains stability across a broad pH range and is resistant to enzymatic degradation. The polymer's ability to increase viscosity at low concentrations makes it an efficient thickener in gel-based formulations.

Additionally, HPMC exhibits good adhesion to the skin and mucous membranes, making it valuable in topical medications and wound dressings. Its low toxicity and hypoallergenic nature contribute to its widespread use in pharmaceutical and cosmetic industries.
