Application of Hydroxyethyl Cellulose(HEC)1 This article continues to introduce the application of hydroxyethyl cellulose(HEC) ●Cosmetics and detergents HEC is an effective film former, binder, thickener, stabilizer and dispersant in shampoos, hair sprays, neutralizers, hair conditioners and cosmetics. Its thickening and protective colloid properties can be used in liquid detergent and solid detergent industries. HEC dissolves
●Agriculture Hydroxyethyl cellulose (HEC) can effectively suspend solid poisons in water-based sprays. When HEC is used in spraying operations, it can play the role of adhering the poison to the leaves; HEC can be used as a thickener for spray emulsions to reduce drug drift, thereby increasing the use effect of foliar spraying. HEC can
HEC(Hydroxyethyl cellulose) is used as an additive in various aspects. This article briefly introduces the main characteristics of HEC. Thickening Hydroxyethyl cellulose (HEC) is an ideal thickener for paints and cosmetics. In practical application, the combination of its thickening property, suspending property, safety, dispersibility and water retention will produce more ideal effect. Pseudoplasticity Pseudoplasticity is
What is Hydroxyethyl Cellulose Hydroxyethyl cellulose (HEC) is an important hydroxyalkyl cellulose. It was successfully prepared by Hubert in 1920. And it is also a water-soluble cellulose ether with a large production volume in the world. It is an important cellulose ether with the largest output and rapid development after CMC and HPMC. At present,
HPMC and HEMC have similar roles in building materials. It can be used as dispersant, water retaining agent, thickener and binder, etc. It is mainly used in the molding of cement mortar and gypsum products. Used in cement mortar to increase its cohesiveness, workability, reduce flocculation, improve viscosity and shrinkage, and have water retention, reduce
The most commonly used mixed solvents for ethyl cellulose (DS: 2.3~2.6) are aromatic hydrocarbons and alcohols. Aromatics can be benzene, toluene, ethylbenzene, xylene, etc., with an amount of 60-80%; alcohols can be methanol, ethanol, etc., with an amount of 20-40%. Slowly add EC to the container containing the solvent under stirring until it is completely
1. Application in the pharmaceutical industry Application in dispersion formulations. Dispersed preparations include injections, internal medicines, external medicines and the like. In order to meet the different requirements of treatment, the medicines are usually made into the above-mentioned various dosage forms, for example: dispersed preparations, tablets, granules, pills, etc. Others can be used in artificial
Hydroxypropylmethylcellulose (HPMC) Hydroxypropylmethylcellulose (HPMC) is a kind of cellulose variety whose output and consumption have increased rapidly in recent years. It is made of refined cotton after alkalization treatment. Using propylene oxide and methyl chloride as etherifying agent, it is a non-ionic cellulose mixed ether prepared through a series of reactions. The degree of substitution
Ⅱ. Traditional water retention methods The traditional solution is to water the base, but it is impossible to ensure that the base is evenly moistened. The ideal hydration goal of cement mortar on the base is: the cement hydration product penetrates into the base along with the process of the base absorbing water, forming an
Ⅰ. The necessity of water retention The water retention of mortar refers to the ability of mortar to retain water. Mortar with poor water retention is easy to bleed and segregate during transportation and storage, that is, water floats on the top, sand and cement sink below, and must be re-stirred before use.
