The hydroxypropyl methyl cellulose is a Methyl cellulose propanediol ether, in which hydroxypropyl and methyl groups are bound by ether bonds to cellulose's anhydrous glucose ring. It is a non-ionic cellulose ether and is easily dispersed in cold water, the solution can form film after drying, and the water solution has the characteristics of pseudoplastic fluid and agitation. When heated, reversible thermogels are formed. The formation temperature of the gels depends on the relative content and degree of substitution of methyl and hydroxypropyl groups, but when heated, the surface tension increases, which is the opposite of the common Surfactant properties, concentration at the interface makes the interfacial concentration much higher than the concentration in the solution. Commonly used as food water-holding agent, reversible thermogel can avoid all kinds of fillings (steamed buns, dumplings, etc.) due to over-heating and shrinkage of“Hair dry”, used for french fries, etc. can reduce the oil content and oil consumption of products, the function of increasing the surface activity and stabilizing the foam can lead to the increase of the volume of the baked products and the formation of good structure in the bread mixed with rice flour or soybean flour.
In the case of fabrics, hydroxypropyl methyl cellulose is a stain-resistant re-adsorption component that is preferentially adsorbed to the surface of the fiber during washing to prevent the re-deposition of dirt on the surface, which can be washed off during rinsing. This is probably“Soil release”, also known as soil antiredeposition . The hydroxypropyl methyl cellulose HPMC is a non-ionic thickener. Different types of HPMC have different viscosity and can improve the fluid. Can be applied to detergents, shampoo, Body Wash, facial cleanser, can also be applied to the thickening of emulsion system.
In the use of detergent advantages:
1.As a non-ionic thickener, thickening of the surface active system viscosity with temperature changes more stable, not like adding Nacl cold easy jelly.
2.Anti-electrolyte.
3.Improve the fluid of the system, have the feeling of drawing, at the same time make the cleaning effect smoother, improve the skin feeling, improve the dry and wet combing of hair, but it is easy to condense in cold water, so pay attention to the correct way to dissolve HPMC.
