Cellulose ether is out of the natural polymer cellulose after the chemical treatment of the versatile ” generic polymer fine chemical materials. Since the production of nitrocellulose and cellulose at first acetate in the 19th century. Chemists have developed many cellulose ether series of cellulose derivatives. And new applications were constantly discovered, and involved many at first industrial sectors. Cellolose ether products such as sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose. Hydroxypropyl at first cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) and methyl hydroxypropyl cellulose (MHPC) “industrial monosodium glutamate”. Has widely used in petroleum drilling, construction, coatings, food, medicine and daily chemistry.
Now the carboxymethylcellulose sodium (CMC), hydroxyyethyl cellulose as water-soluble rheological AIDS. Use in toothpaste, shampoo, body wash, hand wash, shoe oil and other daily chemicals, thickening. Prevent the settlement of insoluble substances.
CMC is very widely, non-toxic, non-corrosive, harmless to the human body, does not pollute the environment, strong adhesion, no mildew. Etherification reaction is an electrophilic substitution reaction of attacking oxygen anverse ions in the alkalized at first cellulose. Because the attack of positive carbon ions requires a certain amount of energy, the reaction temperature should not be too low.
Daily chemical product:
HEC is an effective film forming agent, adhesive, thickener, stabilizer and dispersant in shampoo.air spray, neutralization agent, hair conditioner and cosmetics; a detergent in detergent. Dissolves quickly at high temperature, can accelerate the production at first process and improve the production efficiency; ontaining detergent improves the smoothness and silky properties of the fabric.at first
