Hydroxypropyl methylcellulose (HPMC) is a multifunctional ingredient widely used in cosmetics and belongs to non-ionic cellulose ethers.

1. Thickener and stabilizer
HPMC can effectively increase the viscosity and consistency of cosmetic products, so that the formula can achieve appropriate rheological properties. Its aqueous solution presents a uniform and stable viscous state and can be used in products such as emulsions, gels, and facial cleansers to improve the feel and appearance of use. At the same time, HPMC has a good stabilizing effect on multiphase systems such as emulsions, which helps to prevent stratification and precipitation.

2. Film former
HPMC has good film-forming properties and forms a soft and breathable film on the skin and hair, which can provide protection and lock in moisture. For example, it can make hair more shiny and smooth in hair care products, and play a role in moisturizing and barrier protection in skin care products.

3. Moisturizing and water control
Since HPMC is easily soluble in water and has high water retention, it can form a water-containing moisturizing layer on the skin surface. Its hygroscopicity helps reduce the loss of moisture in the skin and maintain the skin’s moisturizing feeling. HPMC is an ideal additive in moisturizing products such as facial masks and eye creams.

4. Suspension and dispersion effect
HPMC can effectively improve the suspension performance of insoluble substances in the formula in the solution, so that fine particles or pigments are evenly distributed in the matrix to prevent particles from sinking or agglomerating. It is often used in makeup products (such as foundation liquid, mascara) to optimize texture and color uniformity.

5. Mildness and low irritation
HPMC is a chemically modified product of natural origin with extremely low sensitization and irritation, suitable for use in sensitive skin care products. In addition, it is safer and is not easy to cause skin discomfort or allergic reactions, so it is widely used in infant skin care products and high-end cosmetics.

6. Adjust product touch and skin feel
HPMC can give cosmetics a delicate and smooth touch, improve the application experience, and avoid the product being too sticky. Especially in gels, eye care products or sprays, it can significantly improve the comfort during use.

7. Biocompatibility and environmental protection
As a biodegradable material, HPMC is environmentally friendly, and because it is derived from plant cellulose, it meets the cosmetics industry’s demand for natural, safe and sustainable development.

Common application areas
Skin care products: such as moisturizers, essences, facial masks, and eye creams.
Hair care products: such as conditioners and styling gels.
Cosmetics: such as mascara, foundation, and lipstick.
Cleaning products: such as facial cleansers and cleansing foams.
Hydroxypropyl methylcellulose has a wide range of application prospects in cosmetics due to its versatility and safety. It can not only meet the needs of formula design, but also enhance the user experience of the product. Its addition makes cosmetics more excellent in texture, stability, and feel of use, while meeting consumers’ demand for natural, safe, and environmentally friendly products.
