hydroxypropyl methylcellulose HPMC in Plastering MortarFebruary 2nd 2023
Daily chemical grade hydroxypropyl methyl cellulose is a synthetic high molecular polymer prepared by chemical modification with natural cellulose as raw material. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its most basic material is cellulose, a natural polymer compound. Due to the special structure of natural cellulose, cellulose itself has no ability to react with etherifying agents. But after the swelling agent is treated, the strong hydrogen bonds between and within the molecular chain are destroyed, and the active release of the hydroxyl group turns into reactive alkali cellulose. After the etherification agent reacts, the -OH group is converted to the -OR group. Obtain cellulose ether.
Daily chemical grade special 200,000 viscosity instant hydroxypropyl methylcellulose is a white or slightly yellow powder, and it is odorless, tasteless and non-toxic. It can be dissolved in cold water and organic solvents to form a transparent viscous solution. The water liquid has surface activity, high transparency, strong stability, and dissolves in water without being affected by pH. It has thickening and anti-freezing effects in shampoos and shower gels. It has water retention and good film-forming properties for hair and skin. With the substantial increase in basic raw materials, the use of cellulose (antifreeze thickener) in shampoos and shower gels can greatly reduce costs and achieve desired results.
Characteristics and advantages of daily chemical grade cellulose HPMC:
1. Low irritation, high temperature and sex;
2. Broad pH stability, which can guarantee its stability in the range of pH 3-11;
3. Enhance conditioning;
4. Increase foam, stabilize foam and improve skin feel;
5. Effectively improve the fluidity of the system.
Application range of daily chemical grade cellulose HPMC:
Used in shampoo, body wash, facial cleanser, lotion, cream, gel, toner, conditioner, styling products, toothpaste, saliva, toy bubble water.
The role of daily chemical grade cellulose HPMC:
In cosmetic applications, it is mainly used for cosmetic thickening, foaming, stable emulsification, dispersion, adhesion, film formation and improvement of water retention performance, high viscosity products for thickening, and low viscosity products for suspension and dispersion. Film formation.
Technology of daily chemical grade cellulose HPMC:
The viscosity of hydroxypropyl methyl fiber suitable for the daily chemical industry is mainly 100,000, 150,000, and 200,000. The amount of addition in the product is generally three to five thousandths according to your own formula.
