Application of HPMC in daily chemical industry

Hydroxypropyl methylcellulose (HPMC) is a nonionic cellulose ether obtained by etherification modification of natural cellulose. With its excellent water solubility, thickening, film-forming, water retention, and safe, non-toxic and non-irritating properties, HPMC has become an important multifunctional additive in the construction, medicine, food, coatings and daily chemical industries. In the field of daily chemical industry, HPMC is widely used in detergents, skin care products, hair care products, toothpaste and other products due to its excellent performance and green environmental protection properties.

Core performance advantages:

Excellent water solubility: It can be quickly dispersed and dissolved in cold water to form a transparent viscous solution with good compatibility.

High safety: Non-ionic, non-toxic and non-irritating, suitable for skin contact products.

Excellent thickening and rheology control: Provide a wide range of viscosity grades to accurately meet the consistency requirements of different products.

Strong chemical stability: Tolerant to strong acid, strong alkali and high salt environment, and good compatibility with a variety of active ingredients.

Highly efficient film-forming and moisturizing: It can form a flexible protective film on the surface of skin and hair, significantly improving the moisturizing effect and comfort of use.

Application in daily chemical products:

Shampoo and conditioner: As a thickener and stabilizer, it provides suitable viscosity and smooth skin feel, ensures that particulate ingredients (such as pearlescent agents, extracts) are evenly suspended, and enhances product stability.

Facial cleansing and bath products: Regulate foam characteristics, optimize the feel and moisturizing properties, stabilize the surfactant system, prevent stratification, and improve the skin feel after rinsing.

Skin care lotion and cream: It has both emulsifying stability and moisturizing effects. The protective film it forms effectively locks in water, increases the water content of the skin, and has high stability without affecting the efficacy of active ingredients.

Facial mask and gel products: As a core film former and texture regulator, it gives the product a refreshing gel texture and good ductility. The transparent film formed has strong adhesion and promotes the penetration of active ingredients.

Toothpaste: It provides thickening and suspension effects, ensures the stability of the paste, and prevents dehydration and segregation. Its film-forming property helps improve the comfort of oral cleaning.

Shaving and men's care products: Enhance lubricity and ductility, reduce shaving irritation and skin damage, and improve the user experience.

Application points:

Dissolution method: It is recommended to disperse and dissolve in cold water, or first moisten with a small amount of warm water and then stir and dissolve to avoid agglomeration caused by direct addition of high temperature.

Viscosity selection: Select the corresponding grade of HPMC according to product requirements (such as low viscosity for transparent shampoo, medium and high viscosity for cream).

Compatibility verification: Although the compatibility is good, the compatibility and stability of all components of the formula are still required.

Development trend:

As the market demand for natural, safe and environmentally friendly daily chemical products grows, HPMC, as a green additive with excellent performance and natural source, will continue to increase in importance. In the future, HPMC derivatives through chemical modification (such as cross-linking and microencapsulation) are expected to show greater potential in subdivided functional fields such as anti-pollution, oil control, soothing and anti-allergy.

Conclusion:

HPMC has become an indispensable key raw material in modern daily chemical formulations due to its multiple functions such as thickening, stabilization, emulsification, film formation and moisturizing. Its excellent comprehensive performance provides solid technical support for improving product quality and user experience, and has broad application prospects.
