Product introduction

HEMC is made from highly pure cotton - cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents.

HEMC is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water, HEMC will swell into colloidal solution and its solubility is not influenced by PH value. Similar to methyl cellulose while being added to hydroxyethyl groups, HEMC is more resistant to saline, easily soluble in water and has higher gel temperature.

Q:Is there pure food on the market with food additives? What is it?
1,2 floor completely talk ... that is a drink, pure milk is 100% milk, absolutely no additives, plus called milk drinks. Pure milk is made of fresh milk antivirus, pasteurization of the shelf life of short, good nutrition, high temperature sterilization of long shelf life, poor nutrition. And pure milk can not extract fat or add fat, can not add anything, that is, milk. Restore milk, milk drinks what can not be pure milk than the ratio.
Q:How many kinds of additives are included in the drink
not sure! Because some belong to the corporate secret is not announced!
Q:Find the additive inverse of -9 on the 12-hour clock?
The additive inverse is the number that makes another number equal to zero when added. For example, 4 and -4 are additive inverses because -4 + 4 = 0. On a clock, there is no zero. 12 represents zero. To find the inverse of -9 on the 12 hour clock, find the number that adds to -9 to make 12. Subtract -9 from 12 or use algebra: -9 + x = 12 x = 21 The additive inverse of -9 on a 12 hour clock is 21. Hope this helps!
Q:Whats additive toxicity?

Q:What are the types of paint additives?
User's answer more types of additives. Commonly used hardeners, retarders, matting agents and softeners.

Q:Can food additives be eaten directly? why?
According to China's Food Sanitation Law (1995), food additives are for the improvement of food color, aroma, taste and other quality, as well as the need for corrosion and processing technology to join the food in the synthetic or natural substances.
