Problems solved by technology

Although the microcapsule essence particles are very small, the solid particles will be deposited under the influence of gravity. On the other hand, due to the large phase interface and interface energy, the solid particles always have a tendency to automatically aggregate with each other and reduce the interface, which is the so-called thermodynamic instability.
Laundry liquid products generally have a shelf life of about 2 years. When stored for a long time, the microcapsule essence will gradually settle at the bottom, affecting the use effect of the product

preparation example Construction

[0035] The present invention also provides the preparation method of above-mentioned microcapsule essence laundry liquid, comprises the steps:

[0036] 1) According to the percentage by weight, first mix the cationic polyacrylamide and the acrylate nonionic surfactant uniformly to obtain the mixture A.

[0037] 2) Add other nonionic surfactants to A one by one, and stir evenly to obtain mixture B, set aside;

[0038] 3) Prepare the anionic surfactant first; mix the prepared anionic surfactant with the solvent evenly, and stir to obtain the mixture C;

[0039] 4) Mix mixture B and mixture C evenly, add microcapsule essence, preservative, chelating agent and other ingredients, and stir evenly.

[0040] In the step 3), the anionic surfactant is generally completed in the configuration of the laundry detergent, and it is ready-to-use and ready-to-use. It is usually prepared by neutralizing the corresponding acid with an alkaline neutralizer. Alkaline neutralizing agents such as...

Abstract

The invention relates to a microcapsule essence laundry detergent and a preparation method thereof. The microcapsule essence laundry detergent comprises a surfactant system, 0.01-5% of a microcapsuleessence and 0.1-10% of cationic polyacrylamide; wherein the surfactant system is composed of an anionic surfactant and a nonionic surfactant; the nonionic surface active agent comprises an acrylate nonionic surface active agent. According to the microcapsule essence laundry detergent disclosed by the invention, cationic polyacrylamide is adopted to stably disperse the non-water-soluble microcapsule essence; cationic polyacrylamide with low cationic degree is selected to be compatible with the anionic surfactant and the nonionic surfactant, electrostatic repulsion with the anionic surfactant isreduced, and meanwhile, the acrylate nonionic surfactant is adopted to solubilize anionic and cationic associates, so that stable compatibility of various raw materials in a formula system is realized.

Description

technical field [0001] The invention belongs to the technical field of detergent production, and in particular relates to a microcapsule essence laundry detergent and a preparation method thereof. Background technique [0002] Adding microcapsule essence to laundry detergent can achieve the effect of long-lasting fragrance. When fabrics are washed, the microencapsulated fragrance particles are deposited on the fabric fibers. When the fabric is dried, folded, and worn, physical friction is constantly generated, and the wrapping layer of the microcapsule essence is broken, and the fragrance is gradually released to achieve long-lasting fragrance. The film-forming agents commonly used in microcapsule flavors include polymer materials such as gelatin, resin, and chitosan, which cannot be compatible with the main components in laundry detergent and form a stable and uniform form. Although the microcapsule essence particles are very small, the solid particles will be deposited u...
