Daily chemical grade hydroxypropyl methyl cellulose is a water-soluble polymer, its appearance is white or yellowish powder, tasteless and odorless. Soluble in cold water or organic mixed solvents to form a transparent viscous solution. The aqueous solution has high transparency, good surface activity and strong stability. It is not affected by pH when dissolved in water. It can also be used in shampoo and body wash, which can reduce production costs and achieve better results. Widely used in shampoo, body wash, facial cleanser, lotion, cream, gel, toner, conditioner, styling products, toothpaste, mouthwash, toy bubble water. It has thickening and anti-freezing effect in shampoo and body wash, and has water retention and good film formation for hair and skin. HPMC is widely used in the detergent and cleaning industry, and its good stability, thickening, moisturizing, cleaning and foam regulation can bring many advantages. It has become one of the indispensable ingredients in modern cleaning products.

In the application of cosmetics, it is mainly used for thickening, foaming, stable emulsification, dispersion, adhesion, film formation and improving the water retention function of cosmetics. High viscosity products are used for thickening, low viscosity products are mainly used for suspension dispersion and film formation. The viscosity applicable to the daily chemical industry is mainly 100,000, 150,000 and 200,000. The amount added to the product is generally three-thousandths to five-thousandths, and the specific situation is determined according to their own formula.

The advantages of daily chemical grade hydroxypropyl methyl cellulose are as follows:

1.low irritation, high temperature and.

2.increase and stabilize foam, improve skin texture.

3.Put more emphasis on rationality.

4.wide pH stability, can ensure the stability of the pH range 3-11.

5.Effectively improve the liquidity of the system.

Hydroxypropyl methyl cellulose (HPMC) is also widely used in the washing and care industry, and its role includes the following aspects:

1.moisturizer: has a good moisturizing effect, can be used as a moisturizer, in the washing and washing products mainly play a role in lubricating and moisturizing the skin.

2.stabilizer: can be used as a stabilizer to help maintain the stability of various ingredients in shampoo, hair conditioner and body wash, cosmetics and other products.

3.It can prevent the separation of chemical components during storage and transportation, thus ensuring the quality of the product.

4.thickening agent: can be used as a thickening agent in products such as shampoo, hair care and hair conditioner and shower gel. Hydroxypropyl methyl cellulose can improve the viscosity and thickness of products, making these products easier to use and more comfortable.

5.foam regulator: can be used as a foam regulator, can help adjust the size of the foam in the product and the quality of the foam, making the product more comfortable and easy to use.

6.cleaning agent: hydroxypropyl methyl cellulose can be used as a cleaning agent, can increase the surfactant effect of washing products, remove surface dirt and stains, make hair and skin more clean.

Characteristics and application analysis of daily-grade hydroxypropyl methyl cellulose ether

Hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic polymer, which is mainly prepared by etherification reaction of refined cotton. It can be quickly dissolved in cold water to form a transparent viscous solution, with thickening, bonding, dispersion, adsorption, gelling, emulsification, film formation, suspension, surface activity, water retention and colloidal protection properties. Daily chemical grade cellulose is mainly used in textile chemicals, daily chemical washing products, cosmetics and other fields.

1.high water retention: HPMC has high water retention performance, added to slurry, paste, paste products can maintain high water retention.

2.viscosification and thickening performance: increase a small amount of HPMC, to be dissolved to form a transparent viscous solution, high transparency, stable performance, its solubility will change with the viscosity, the lower the viscosity, the greater the solubility. It can effectively improve the flow stability of the system.

3.water solubility and thickening performance: can quickly dissolve in cold water, but also soluble in some organic solvents and water and organic solvents mixed solution.

4.low stimulation, mild and stable performance.

5. surface activity: aqueous solution has surface activity, with emulsification, protection of colloids and relative stability and other effects and properties. The surface tension is 42-56dyn/cm in 2% aqueous solution.

6.PH stability: the viscosity of aqueous solution is relatively stable in the range of PH3.0-11.0.

7.salt resistance: hydroxypropyl methyl cellulose is a non-ionic polymer, in the aqueous solution of organic electrolyte or metal salt is relatively stable.

8.hot gelling: when the aqueous solution is heated to a certain temperature, it will become opaque until the flocculation state is generated, so that the solution loses viscosity. But as it cools, it will return to its original solution. The temperature at which the gel phenomenon occurs depends on the type of product, the concentration of the solution, and the rate of heating.

9.other characteristics: good film formation, as well as a wide range of enzyme resistance, adhesion and dispersion characteristics.
