Embodiment 1

[0038] A) Synthesis of Cationic Polymers This example describes the preparation of suitable cationic polymers.

[0039] The aqueous phase of the water soluble polymer is prepared by mixing together the following components:

[0040] — 47.0 parts of dimethylaminoethyl methacrylate chloride quaternary ammonium salt,

[0041] - 6.0 parts of acrylamide,

[0042] - 0.03 parts of pentasodium diethylenetriamine pentaacetate,

[0043] — 14 parts water,

[0044] — 0.03 parts of methylenebisacrylamide,

[0045] - 0.4 parts of sodium formate,

[0046] -Use citric acid to adjust the pH value to between 4.0-6.0.

[0047] The oil phase is prepared by mixing together the following components:

[0048] — 2.0 parts of sorbitan monooleate,

[0049] - 5.5 parts polymer stabilizer,

[0050] — 19.0 parts white mineral oil,

[0051] - 6.0 parts dearomatized hydrocarbon solvent,

[0052] The two phases are mixed together in a high-shear rate reactor at a ratio of 1 part of oil to 1 part ...

Abstract

Cationic polymer thickener consisting of a crosslinked water swellable cationic polymer containing at least one cationic monomer and optionally non-ionic and or anionic monomers wherein said polymer comprises less than 25% of water soluble polymeric chain by total weight of the polymer, and a cross-linking agent concentration of from 500 ppm to 5000 ppm relative to the polymer.

Description

technical field [0001] The invention relates to the technical field of cationic cross-linked polymer and its application as a thickener. Background technique [0002] Traditionally, most domestic fabric softener compositions contain thickeners to provide rheological improvements. [0003] Standard cationic polymeric thickeners are crosslinked water swellable polymers such as those disclosed in WO90 / 12862 (BP Chemistry) which discloses the use of lightly crosslinked (5-45ppm) cationic thickeners , or US2002 / 0132749 (Colgate-Palmolive) and the application of the heavily cross-linked cationic thickener disclosed in "Research Disclosure" 429116. [0004] One disadvantage of softener treatments is the gradual over-accumulation of softener components on the surface of the garment, especially after repeated use. This excess build-up on clothing creates a positive charge and tends to interact more strongly with dirt and oil, which usually have a negative charge. This makes dirt a...
