Abstract

The invention belongs to the technical field of whitening agents and a preparation method thereof and relates to a liquid fluorescent whitening agent for whitening soup and a preparation method thereof. The liquid fluorescent whitening agent mainly solves the technical problem that the existing liquid fluorescent whitening agent for whitening soup can pollute the environment, has poor storage stability, has a high production cost and has poor whitening effects. Through processes, the transparent mixed liquid whitening agent is prepared from difficultly soluble whitening agent dye I and soluble whitening agent dye II under the condition of dispersion and solubilization of other materials. The liquid fluorescent whitening agent has the characteristics of excellent fabric whitening performances of the whitening agent dye I and excellent base whitening performances of the whitening agent dye II, improves comprehensive decontamination performances of the whitening soup and improves whitening soup appearance whiteness. The liquid fluorescent whitening agent is a liquid, can be directly used for whitening soup processing production, simplifies operation processes, reduces dust-caused environmental pollution and is conducive to automatic charging.

Description

technical field [0001] The invention belongs to the technical field of whitening agents and preparation methods thereof, and in particular relates to a liquid fluorescent whitening agent for whitening soap and a preparation method thereof. Background technique [0002] Soap is a traditional cleaning product. It still occupies a certain market in the cleaning product because of its natural raw materials, no irritation to the skin left on the fabric after washing, convenient use of local scrubbing, good decontamination effect, and easy rinsing. share, and with the increase in the production and sales of washing products, it is also growing at a rate of 2%. Whitening soap, as a large category of soap, has a white appearance and has the characteristics of whitening and brightening the washed fabrics more than ordinary soaps. It is especially suitable for partial rubbing of heavy stains such as collars and cuffs, and is more popular favored by consumers. Fluorescent whitening a...
