What is hydroxypropyl methylcellulose used for?

Hydroxypropyl methyl cellulose is also called HPMC. Hydroxypropyl methyl cellulose HPMC is a non-ionic cellulose ether prepared by a series of complex chemical processes with natural polymer material refined cotton as the main raw material.

HPMC is widely used, which is widely used in chemical industry, construction, building materials, coatings, food, cosmetics, agriculture, national defense and military industry and other fields.

The following is a detailed introduction to the use of HPMC in various aspects:

1. Application of HPMC in concrete

Hydroxypropylmethylcellulose has good thickening effect and is often used as a concrete anti-dispersant. In the past, Hydroxypropylmethylcellulose is a relatively scarce fine chemical product in China, and its cost is relatively high. With the continuous development and progress of external wall thermal insulation technology in recent years, and the excellent characteristics of Hydroxypropylmethylcellulose itself, It has been widely used in the construction industry.

2.Application of HPMC in daily chemical skin care products

In the application of HPMC for daily chemical washing, HPMC is mainly used to improve the thickening, foaming, stable emulsification, dispersion, adhesion, film formation and water retention of cosmetics, and in low-viscosity products, it is mainly used for suspension dispersion and film formation.

The viscosity of the daily chemical industry mainly includes 100000, 150000 and 200000. You can choose the amount of additives in the product according to your own formula, usually about 3 to 5 ‰. Hydroxypropyl methyl cellulose is widely used in daily chemical skin care products, such as facial cleanser, lotion, shampoo, bath liquid, cream, gel, toner, hair conditioner, styling products, toothpaste, mouthwash, toy bubble water, etc.

3. Application of HPMC in putty powder

After the hydroxypropyl methyl cellulose is dissolved in the putty powder, the methoxy and hydroxypropyl groups on its molecular chain act with the aluminum ions and calcium ions in the putty powder, and then generate viscous gel, which is filled in the gaps of the putty powder, thus greatly improving the compactness of the putty powder, playing the role of reinforcement and flexible filling. However, when the composite matrix is pressed, the polymer can not play a rigid support role, thus reducing the strength and compression ratio of putty powder.

4. Application of HPMC in daily chemical washing

HPMC is a surface-treated product, which can be quickly dispersed in water and will not agglomerate. HPMC has the advantages of good thickening effect and high transparency, and is especially suitable for thickening products such as daily chemical products. The solution system has good stability, and can be non-layered, non-thinning and anti-mildew for a long time. Daily chemical grade instant HPMC is usually used in daily chemical washing products, such as hand sanitizer, laundry detergent, car wash, etc.

5. Application of HPMC in textile printing and dyeing

It is mainly used as thickener, dispersant, binder, excipient, oil-resistant coating, filler, emulsifier and stabilizer in textile printing and dyeing industry. It is also widely used in synthetic resin, leather, medicine, food, petrochemical, ceramics, paper and cosmetics industries.

6. Application of HPMC in building materials

Hydroxypropylmethylcellulose is a common building material additive, which is widely used in building materials and can be divided into many types. Hydroxypropylmethylcellulose can be divided into hot-soluble and cold-water quick-soluble types.

Hot-soluble HPMC is often used in dry powder products, directly mixed with dry powder for uniform use, such as in putty powder and mortar, while cold-water quick-soluble HPMC is often used in liquid glue, mortar, putty powder In liquid coatings and daily chemical products, HPMC can be widely used to transmit the performance of gypsum, cement and other hydrate building materials, especially in cement-based mortar, which can improve its water retention, thus extending the correction time and opening time, and reducing the problem of flow suspension.

Is hydroxypropyl methyl cellulose safe?

Health has always been a major concern. Generally, chemical raw materials are used in the construction industry. We need to carry out relevant tests for their radiation, toxic and side effects when they are used to prevent their impact on our health. The safety advantages of hydroxypropyl methyl cellulose and other raw materials are in good agreement with our use standards, so the application of such raw materials is also quite common.

HPMC is the leading product of our company, which is widely used in chemical industry, construction, building materials, coatings, food, cosmetics, agriculture, national defense and military industry and other fields. The company has passed the ISO9001 quality system certification, and the product quality has reached the international advanced level. The variety and quality meet the needs of domestic and foreign merchants. The company’s strong economic strength and rich human resources have laid a solid foundation for the company’s long-term development. Excellent quality, superior price and considerate service are the goals of our company. We are willing to work together with customers at home and abroad to create brilliant future!
