Daily chemical grade hydroxypropyl methyl cellulose is a synthetic polymer and chemically modifie from natural cellulose. Cellulose ether is a derivative of natural cellulose, and the cellulose ether production is different from the synthetic polymer, and its most basic material is fiber Vyins, natural polymer compounds. Due to the particularity of the natural cellulose structure, the cellulose itself does not react with the etherification agent capability of. However, after the treatment of the billant, the strong hydrogen bonds between and within the molecule are destroye, and the activity of the hydroxyl group is release Into a reactive alkali cellulose. After the ether chemical agent reaction one-OH group into an OR group to obtain cellulose ether. HPMC
Daily chemical grade special hydroxypropyl methyl cellulose is a white or slightly yellow powder, and odorless, tasteless, non-toxic.ability Solvents dissolved in cold water and organic matter to form a transparent and sticky solution. Water use has surface activity, high transparency, strong Stability, dissolve in water was not affecte by pH. In shampoo, shower gel in the thickening, antifreeze effect, hair, skin Have water retention and good film formation. With the sharp rise in basic raw materials, cellulose (antifreeze thickener) is use in shampoo Body gel can also greatly reduce costs and achieve the desire results.HPMC
Characteristics and advantages of cosmetic grade cellulose HPMC:
- Low irritation, high temperature and sex;
- 2. Broa stability of pH value can be guarantee within the range of pH value 3-11;
- 3. Enhance rationality adjustment;
- 4. Increase bubble, stabilize bubble, improve skin feeling;
- 5. Effectively improve the liquidity of the system.
