Problems solved by technology

The huge difference in rheological properties of liquid washing products in high and low temperature environments brings great inconvenience to users. For example, in hot summer, the liquid in the bottle will leak or be squeezed out too much. more, and in the colder winter, sometimes there is a phenomenon that cannot be squeezed out at all

Abstract

The invention provides a synthetic cationic high-polymer polyquaternary amine salt with rheologic modification function, which is polymerized from the following components in parts by weight in a water solution environment: 7-14 parts of dimethylaminoethyl methacrylate, 3-10 parts of acrylic acid, 0.5-5 parts of allyl polyethyleneglycol, 0.3-3 parts of ammonium persulfate, 1-7 parts of hydrochloric acid, 0.1-6 parts of 10% sodium sulfite water solution and 53-88 parts of deionized water. On the premise of not losing cationic polyquaternary amine salt characteristics, the polyquaternary amine salt provided by the invention has favorable rheologic modification function, and can be used as a conditioner in liquid washing products, such as shampoo, body wash, liquid soap and the like. Due to the properties, the polyquaternary amine salt can enable the liquid washing product to have stable rheological properties in both high and low temperature environments, and is especially suitable for improving the rheological properties under low temperature conditions, thereby enhancing the service convenience of the product.

Description

technical field [0001] The present invention relates to a polyquaternium salt, in particular to a polyquaternium salt capable of improving the rheological properties of liquid products, and more specifically to a synthetic cationic polymer polyquaternium salt with a rheological modification function. The invention also relates to the use of such polyquaternium salts in washing products. Background technique [0002] Cationic polyquaternary ammonium salts can be divided into plant polymer modified cationic polymers, cellulose modified cationic polymers, and synthetic cationic polymer polyquaternium salts, among which plant polymer modified cationic polymers, fiber The prime-modified cationic polymer has cationic function and thickening function for the system, and belongs to multifunctional cationic conditioning agent, while the artificially synthesized cationic polymer polyquaternary ammonium salt has a single function, but it can be more targeted. Due to its good solubilit...
