Daily chemical grade hydroxypropyl methylcellulose is a synthetic polymer made from natural cellulose through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its most basic material is cellulose, a natural polymer compound. Due to the particularity of the natural cellulose structure, the cellulose itself has no ability to react with etherification agents. However, after the treatment of the swelling agent, the strong hydrogen bonds between the molecular chains and the chains are destroyed, and the active release of the hydroxyl group becomes a reactive alkali cellulose. Obtain cellulose ether.
Daily chemical grade hydroxypropyl methylcellulose is a white or slightly yellowish powder, and it is odorless, tasteless and non-toxic. It can be dissolved in cold water and mixed solvent of organic matter to form a transparent viscous solution. The water liquid has surface activity, high transparency, strong stability, and is not affected by pH when dissolved in water. It has thickening and antifreeze effects in shampoos and shower gels, and has water retention and good film-forming properties for hair and skin. With the sharp rise of basic raw materials, the use of cellulose (antifreeze thickener) in shampoo and shower gel can greatly reduce the cost and achieve the desired effect.
Features and advantages of daily chemical grade cellulose HPMC:
1. Low irritation, high temperature and non-toxic;
2. Broad pH value stability, which can ensure its stability in the range of pH value 3-11;
3. Enhance conditioning;
4. Increase foam, stabilize foam, improve skin feel;
5. Effectively improve the fluidity of the system.
The scope of application of daily chemical grade cellulose HPMC:
Used in shampoo, body wash, facial cleanser, lotion, cream, gel, toner, conditioner, styling products, toothpaste, mouthwash, toy bubble water.
The role of daily chemical grade cellulose HPMC:
In cosmetic applications, it is mainly used for thickening, foaming, stable emulsification, dispersion, adhesion, improvement of film-forming and water retention properties of cosmetics, high-viscosity products are used for thickening, low-viscosity products are mainly used for suspension dispersion and film forming.
Daily chemical grade cellulose HPMC technology:
The viscosity of hydroxypropyl methylcellulose suitable for the daily chemical industry is mainly 100,000, 150,000, and 200,000. According to your own formula, the amount of addition in the product is generally 3 to 5/1000.
