Characteristics of Cellulose ethers (1). Product Status: powdery or granular. (2). State of Charge: non-ionic state and anionic state Cellulose ethers in non-ionic state have compatibility with aqueous solutions of other additives, including: 1) Methyl cellulose (MC) 2) Hydroxy ethyl methyl cellulose (HEMC) 3) Hydroxy propyl methyl cellulose (HPMC) 4) Hydroxy ethyl cellulose (HEC) 5).. read more →
The cellulose ether solution is affected by cellulase enzymes and microorganisms. Enzymes first attack unsubstituted anhydroglucose units, which causes the hydrolysis scission of macromolecular chain and leads to reduction in viscosity of products. Ether substituents may play a protective role in the main chain of cellulose. Therefore, the stability of cellulose ether will be improved.. read more →
In the pharmaceutical industry, Microcrystalline cellulose (MCC) is mainly used for two aspects. One is to use the property of easily forming gels in water with vigorous stirring for preparing paste and suspension drugs. The other is to use its molding action for excipients of pharmaceutical tableting. Methyl cellulose (MC) is a methyl ether of.. read more →
As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →
Sodium Carboxymethyl cellulose (CMC) has been one of the important raw materials in the production of toothpaste. Its role is to uniformly mix the liquid and solid raw materials of toothpaste together, and to give toothpaste the molding flow, proper viscosity and a certain brightness as well as delicateness. The toothpaste of common type without.. read more →
In the pharmaceutical industry, hydroxy propyl methyl cellulose (HPMC) can act as pharmaceutical excipients. It is widely used in oral drugs such as matrix controlled-release and sustained-release preparations as the release-blocking material to regulate the drug release, or as sustained-release agents, pellets and capsules of coating materials. The most widely used are dimethyl carboxymethyl cellulose.. read more →
1. Appearance Characteristics The cellulose ether is generally white or milky white, odorless, non-toxic, and in the appearance of fibrous powder with fluidity. It is easy to absorb moisture and dissolves in water into a stable and transparent viscous gel. 2. Thickening Properties The cellulose ether is dissolved in water in the morphology of colloids,.. read more →
In the formulations of building materials, the dosage of cellulose ether is only 0.1% to 1%. But it plays an irreplaceable role. Various applications of cellulose ether in building materials will be introduced as follows. 1. Latex and Latex Building Materials Such cellulose derivatives as MC, CMC, HEC and HPMC can be used in the.. read more →
Emulsifying, Dispersing and Anti-redeposition agents in Washing Products With the soap base as the main active ingredient, the body wash, after use, has no creamy feel of general surfactants , is easy to clean and can protect the skin’s natural luster. HEC has excellent solvent resistance to the electrolyte, and the solution contains high concentrations.. read more →
Solubility of Sodium Carboxy Methyl Cellulose Sodium Carboxy Methyl Cellulose is a natural hydrophilic colloid. Sodium Carboxy Methyl Cellulose particles disperse in water, then immediately swell and dissolve. 1. Under stirring, slowly adding Sodium Carboxy Methyl Cellulose can accelerate the dissolution; 2. In the case of heating, dispersedly adding Sodium Carboxy Methyl Cellulose can improve.. read more →
