Problems solved by technology
[0010] The purpose of the present invention is to provide a thickener based on the problem that the thickener added in the existing fabric softener usually cannot achieve an effective thickening effect, or although it can play a thickening effect, there are still defects in rheological properties. A fabric softener containing a novel water-soluble, highly cationic, cross-linked amphoteric polymer that imparts good thickening and rheological properties to fabric softener products

[0036] experiment number
[0037] experiment number
[0038]According to the dosage in Table 1 above, mix the components in the water phase to form the "water phase".
[0039] In a 250mL reactor, add oily solvent (6 grams of liquid paraffin, 9 grams of cyclohexane) and 2 grams of emulsifier according to the proportions in Table 1. The HLB value of the emulsifier is controlled at 8.0 to 9.0, and the stirring speed is 1000 rpm. Stir for 0.5 h , to make a uniform "oil phase".
[0040] At a stirring speed of 800rpm, N 2 Drain the O from the reaction vessel 2 , slowly drop into the "water phase", control the reaction temperature between 40 ~ 42 ° C, and continue the reaction for 6 hours to obtain a yellowish milky white latex.
[0041] The above-mentioned latex is treated with a polar solvent and ...

Abstract
The invention discloses a fabric softener and a method for preparing the same. The fabric softener comprises the following components in percentage by mass: 0.001 to 5.0 percentage of high-cationic degree crosslinking type amphoteric polymer, 0.5 to 50 percent of cationic surface active agent, 0 to 10 percent of additive, 0 to 2 percent of essence and the balance of water, wherein the high-cationic degree crosslinking type amphoteric polymers are copolymerized by anionic monomers A, cationic monomers B and a crosslinking agent C, and the structural formula of the high-cationic degree crosslinking type amphoteric polymer is BxCyAz. The fabric softener has an ideal rheological property and a high thickening effect.
Description
technical field [0001] The invention relates to the field of fabric softeners, in particular to a fabric softener with excellent rheological properties and good softness. Background technique [0002] For ease of use and the need to improve certain product properties, it is a popular standard practice to include tackifying polymers in household care products to achieve optimal rheological properties. Currently, various types of polymers have been suggested for the purpose of increasing the viscosity of the composition. The rheological properties of household cleaning products are generally controlled using natural or synthetic polymers. Polymers commonly used for thickening include polyacrylate, alkali-swellable latex, modified cellulose, guar gum, and xanthan gum. All of the above are already widely used in laundry and dishwashing liquids, as well as some hard surface cleaners. [0003] However, for products formulated with cationic surfactants, such as fabric softeners,...
