Hydroxypropyl methylcellulose is a kind of propylene glycol ether of methylcellulose, in which both hydroxypropyl and methyl groups are combined with the anhydrous glucose ring of cellulose through ether bonds. It is a non-ionic cellulose ether and is easy to disperse in In cold water, the solution can form a thin film after drying, and the aqueous solution has the characteristics of pseudoplastic fluid and has the effect of stirring and thinning.
In fabric clothes, hydroxypropyl methylcellulose HPMC is an anti-stain and re-adsorption component. When washing, it is preferentially adsorbed to the surface of the fiber to prevent dirt from redepositing, and can be washed away during rinsing. The English concept probably belongs to the role of "soil release" (it can also be considered as anti-redeposition soil antiredeposition, but the former is more vivid).
Hydroxypropyl methylcellulose HPMC is a non-ionic thickener. There are different types of thickeners. Different types have different viscosities and can also improve fluidity. It can be used in detergents, shampoos, shower gels, facial cleansers, and thickening of emulsification systems.
Advantages of using in detergent:
1. As a non-ionic thickener, the viscosity of the thickened surfactant system is relatively stable with temperature changes, and it will not be cold-resistant and easy to jelly like adding Nacl.
2. Electrolyte resistance
3. Improve the fluidity of the system, with a feeling of drawing, and at the same time make the cleaning effect smoother, improve the skin feel, and improve the dry and wet combability of hair
