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 natural cellulose structure, 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. After the reaction of the etherifying agent, the -OH group is converted into an OR group Obtain cellulose ether. The 200,000-viscosity hydroxypropyl methylcellulose for “Max” daily chemical grade is a white or slightly yellowish powder, which 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-use 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.
