Main applications of Hydroxypropyl Methylcellulose

1. Construction industry: As a water retainer and retarder for cement mortar, it makes the mortar pumpable. As an adhesive in plaster, gypsum, putty powder or other building materials, it improves the spreadability and prolongs the operability time. It is used as a bonding enhancer for pasting tiles, marble, plastic decorations, and can also reduce the amount of cement. The water retention property of Hydroxypropyl Methylcellulose HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.

2. Ceramic manufacturing industry: It is widely used as an adhesive in the manufacture of ceramic products.

3. Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. As a paint stripper.

4. Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.

5. Plastics: As a molding release agent, softener, lubricant, etc.

6. Polyvinyl chloride: used as dispersant in the production of polyvinyl chloride, and is the main auxiliary agent for the preparation of PVC by suspension polymerization.

7. Others: This product is also widely used in leather, paper products, fruit and vegetable preservation, and textile industries.

8. Pharmaceutical industry: coating materials; membrane materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet adhesives; tackifiers.

Application skills in the construction field: 1. Mortar additives: HPMC can increase the adhesion and ductility of mortar and improve construction performance. Adding 0.3%-0.5% HPMC to general building mortar can achieve ideal results. 2. Tile adhesives: HPMC can improve the adhesion and water resistance of tile adhesives and prevent tiles from falling. Adding 0.3%-0.5% HPMC can achieve better results. 3. Putty powder: HPMC is used as a modifier in putty powder to improve the crack resistance, adhesion and filling power of putty. The general addition amount is 0.2%-0.5%.

2. Application skills in the field of coatings: 1. Thickener for latex paint: HPMC can improve the viscosity and coating properties of latex paint and improve the construction performance of the paint. Adding 0.2%-0.6% HPMC can achieve the desired effect. 2. Water-based wood paint: HPMC is used as a stabilizer in water-based wood paint to improve the flatness and anti-re-adhesion of the paint film. 3. Isolation film: Adding HPMC to the anti-paint coating can improve the corrosion resistance and anti-adhesion of the oil-proof coating.

3. Application skills in the pharmaceutical field: 1. Sustained release agent: HPMC as a sustained release agent can adjust the release rate of the drug and improve the absorption effect of the drug. The amount of HPMC with different viscosities added to the drug preparation is different, which needs to be determined according to the specific drug and drug preparation. 2. Eye drops: HPMC as a thickener for eye drops can improve the adhesion of the drops and prolong the retention time of the drug in the eye.

4. Application skills in the food field: 1. Vegetable cream: HPMC can be added to vegetable cream to increase the viscosity and stability of the cream. 2. Freeze-dried food: HPMC can be added to freeze-dried food to improve the water retention and shape stability of the food. 3. Beverages: HPMC is used as a thickener and stabilizer in beverages to improve the taste and appearance of beverages.

1. The role of hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose is a natural polysaccharide that has good viscosity control, dispersion stability and moisturizing effects. It plays an important role in cosmetics and skin care products. Its main functions include:

1. Moisturizing effect: Hydroxypropyl methylcellulose has a strong moisturizing effect and can help the skin absorb moisture, thereby keeping the skin moisturized

2. Soft skin: Hydroxypropyl methylcellulose can make the skin softer and smoother.

3. Reduce skin sensitivity: Hydroxypropyl methylcellulose has the effect of relieving skin sensitivity, soothing the skin, and reducing discomfort symptoms such as itching and pain.

2. Skin care products containing hydroxypropyl methylcellulose

1. Hydroxypropyl methylcellulose mask

Hydroxypropyl methylcellulose mask is a product that can deeply moisturize the skin, promote skin metabolism and recovery. It can form a moisturizing film on the surface of the skin, reduce skin moisture loss, promote the skin to absorb nutrients and moisture, and has a good moisturizing effect.

2. Hydroxypropyl methylcellulose lotion

Hydroxypropyl methylcellulose lotion is a product that can weaken skin pollution and form a protective layer. It can make the skin softer and fresher, and fade fine wrinkles. In addition, hydroxypropyl methylcellulose lotion can also regulate the water and oil balance of the skin, and relieve discomfort symptoms such as redness and itching.

3. Hydroxypropyl methylcellulose toner

Hydroxypropyl methylcellulose toner is a product that can improve skin condition and is also suitable for sensitive skin. It can balance the pH value of the skin and reduce the imbalance of oil and water in the skin. It can penetrate deeply to tighten the skin, making the skin soft and elastic.
