If the product fails to meet the specified standards, it may need to undergo further processing or recycling.
  • In the cosmetics and personal care industry, hydroxyethyl cellulose is used in a wide range of products, including shampoos, conditioners, lotions, and creams. It acts as a thickener and stabilizer, improving the texture and consistency of these products. Its film-forming properties create a protective barrier on the skin or hair, preventing moisture loss and enhancing the overall efficacy of the product.
  • The food industry also benefits from HPMC 4000, particularly in the production of food additives and emulsifiers
  • HEC has a long shelf life and maintains its effectiveness over time. This ensures that the products containing HEC continue to provide the desired benefits even after prolonged storage.
  • Answer: hot water solution method: because HPMC is not dissolved in hot water, so the initial HPMC can be evenly dispersed in hot water, then quickly dissolved when cooling, two typical methods are described as follows:
    1) Put the required amount of hot water in the container and heat it to about 70℃. Under the slow stirring gradually add hydroxypropyl methyl cellulose, HPMC began to float on the surface of the water, and then gradually form a slurry, the slurry cooling under the stirring.
    2) Add 1/3 or 2/3 of the required amount of water into the container, and heat to 70℃, according to the method of 1), disperse HPMC, prepare hot water slurry; Then add the remaining amount of cold water to the hot slurry, stirring and cooling the mixture.
    Powder mixing method: HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, then add water to dissolve, HPMC at this time can dissolve, and do not stick together, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method. [Hydroxypropyl methyl cellulose (HPMC) is used as thickening agent and water retaining agent in putty mortar.]
