KDOCEL   Hydroxyethyl Cellulose   (HEC) is one kind of non-ionic soluble   cellulose ether , which can be dissolved in hot or cold water and has the characteristics of thickening, suspending, adhesive, emulsion, film forming, water retention and protective colloid etc., which is widely used in water based paints, following is our lab testing steps to make water based paints using HEC:  1. Add the prescribed amount of water, and add KDOCEL Hydroxyethyl Cellulose at a low speed of stirring, after Cellulose Ether dispersed, then add the prescribed amount of pH agent.     2. Add Bactericidal and mildew repellent agent, Dispersant, Defoamer, Glycol and other auxiliaries in sequence.    3. After dispersing and stirring evenly, increase the stirring speed and start to add pigments and fillers such as titanium dioxide and heavy calcium.  4. Disperse at high speed for 30-40 minutes, then reduce stirring speed, add emulsion, defoaming agent, Texanol ,p...

HPMC  can be divided into quick-dissolving (surface treated) and hot-dissolving (non-surface treated) types. The quick-dissolving product quickly disperses in cold water and disappears into the water. At this time, the liquid is not viscous, because HPMC is only dispersed in water, not really dissolved. About 2 minutes, the viscosity of the liquid gradually increases and forms a transparent viscous gel. For hot soluble type, it clumps in cold water, but in hot water, it disperses rapidly and disappears in hot water until the temperature drops to a certain temperature, then it slowly appears viscous until it forms a transparent viscous colloid. The reason for cold water caking is that the outer layer of cellulose powder encounters cold water and immediately starts to be viscous and thickens into a transparent colloid, while the cellulose inside does not come into contact with water and is surrounded by colloid, or is in powder form but slowly dissolves. In practice, hot water is not...

  What is hydroxypropyl methylcellulose? Hydroxypropyl methylcellulose is a white, odourless, tasteless powder made chemically through the modification of cellulose. Cellulose is a natural polymer – long chains or structures made up of many, many molecules strung together.   The Application of HPMC in Hand Sanitizer In the production process of hand sanitizer, adding an appropriate amount of  Hydroxypropyl methyl cellulose  can effectively thicken. In addition, Hydroxypropyl methyl cellulose is a non-ionic chemical that will play an irreplaceable role in the application of other thickeners, such as stronger stability, cold resistance, anticoagulation, and electrolyte resistance , better fluidity and a more brushed feel, plus the use of Hydroxypropyl methyl cellulose in hand sanitizer resists irritation and makes hand sanitizer gentler. At the same time, it has good water retention and film-forming properties for hand skin. Its biggest advantage is that it is safe, no...

Methyl Hydroxyethyl Cellulose , also known as Methylcellulose and colloquium, is an organic compound methyl hydroxyethyl cellulose uses in various cosmetic and medical applications, the primary one being as a thickening agent. In decorative applications, it's found most often as a component of toothpaste and cough syrups. The compound is tasteless and odorless, and in medicine, it is ingested by patients to relieve constipation, diarrhea, and hemorrhoids. Here are top uses   methyl hydroxyethyl cellulose 1. Thickening agent Methyl hydroxyethyl cellulose  uses to thickener in cosmetic products such as shampoos and conditioners because it can form a film on hair strands. This film makes hair appear smooth and shiny. In addition, the material coats the hair strands to protect them from water damage. Because it is water-soluble, methyl hydroxyethyl cellulose does not cause build-up on hair strands after repeated use of the product containing it. 2. Medicine You may have taken meth...

Hydroxypropyl Starch Ether Product Description Hydroxypropyl starch ether is a starch-based additive designed for dry mortars in the construction industry, imparting unique properties to cement and gypsum-based products. Hydroxypropyl starch ether , which has a similar chemical structure to hydroxypropyl methylcellulose (HPMC), not only provides similar functions to hydroxypropyl methylcellulose (HPMC) , but also has good compatibility with other building aids. Capacitance. Used in conjunction with hydroxypropyl methylcellulose (HPMC), hydroxypropyl starch ether can play a better thickening effect, with better crack resistance and processability. It works well in neutral and alkaline conditions and is compatible with other additives in gypsum or cement-based building materials. The cost of mortar formulations can be significantly reduced by adding starch ethers. Specification of Hydroxypropyl Starch Ether Appearance white or quasi-white powder    Viscocity (5% solution 20...
