Product features
Hydroxypropyl methyl cellulose is propylene glycol ether of methyl cellulose, hydroxypropyl and methyl combine with anhydrous glucose ring by ether bond.It is white or pale white cellulose powder or particles. The characteristics of cold water dissolution and hot water insoluble are similar with methyl cellulose. Soluble in water, its water solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the reversible conversion of sol to gel. To cold drink, the maximum amount is 1%. Hydroxypropyl methyl cellulose and other water-soluble high weight compounds use mixture, become transparent, higher viscosity. The gelation temperature of low viscosity products is higher than high viscosity of products. Its solution is stable at room temperature. In recent years, It has been widely used in petroleum chemical industry, papermaking, leather, textile printing and dyeing, pharmaceutical, food, cosmetics and other industries, and as the dispersing agent, thickening agent, adhesive, excipient, capsule, oil resistant coating and packing etc.

Usage method
Purpose: thickener, emulsifier, stabilizer.
1 note: hydroxypropyl methyl cellulose has many excellent properties.The use of its thermal gel properties can make deep fried food, not only can save a lot of oil, but also the product has a unique taste of the soft. The use of its acid, alkali stability, anti-enzymes, do not participate in metabolism, enhance the characteristics of gastrointestinal motility, but also used to produce a variety of health food.
2 usage range and usage
(1) The provisions on the use of hygienic standards for food additives (GB 2760-1996) shall be used in all kinds of food appropriately.
(2) The actual use of reference: the use of high transparency film and film of this product can be used in the manufacture of casings, dosage is 5%. It is used as a thickener mayonnaise (HPMC), dosage of 0.5%~2%.
