The daily chemical grade hydroxypropyl methyl cellulose is a synthetic polymer prepared by chemical modification of natural cellulose as raw material. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymer is different, its most basic material is cellulose, a natural polymer compound. Because of the particularity of natural cellulose structure, cellulose itself has no ability to react with etherifying agents. However, after the treatment of swelling agent, the strong hydrogen bonds between and within the molecular chains are destroyed, and the activity of hydroxyl group is released into alkali cellulose with reactive ability. After the reaction of etherifying agent, the -OH group is converted into -OR group to obtain cellulose ether.
Daily chemical grade special 200 thousand viscosity instant hydroxypropyl methyl cellulose is a white or slightly yellow powder, and odorless, tasteless, non-toxic. Soluble in a mixture of cold water and organic solvents to form a transparent viscous solution. Water solution has surface activity, high transparency, strong stability, solubility in water is not affected by pH. Thickening and antifreeze effect in shampoo and body wash, water retention and good film formation for hair and skin. With the huge increase in basic raw materials, cellulose (antifreeze thickener) can be used in shampoo and body wash can greatly reduce the cost and achieve the desired results.
1. Characteristics and advantages of daily chemical grade cellulose HPMC:
1, low irritation, high temperature and sex;
2, a wide range of pH stability, in the pH value of 3-11 range can ensure its stability;
3. Increasing emphasis on rationality;
4. Increase bubble, stabilize bubble, improve skin feeling;
5. Effectively improve the system’s liquidity.
2 daily chemical grade cellulose HPMC application scope:
Used in shampoo, body wash, facial cleanser, lotion, cream, gel, toner, conditioner, shaping products, toothpaste, water, toy bubble water.
3 The role of daily chemical grade cellulose HPMC:
In the application of cosmetics, it is mainly used for thickening, foaming, stable emulsification, dispersion, adhesion, film formation and water retention performance improvement, high viscosity products are used as thickening, low viscosity products are mainly used as suspension dispersion and film formation.
4 daily chemical grade cellulose HPMC technology:
Hydroxypropyl methyl fiber to adapt to the viscosity of the chemical industry is mainly 100 thousand, 150 thousand, 200 thousand, according to their own formula to choose the amount of added in the product is generally three to five thousand.
