Abstract

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. The invention mainly solves the technical problems of environmental pollution, unstable storage, high production cost and poor whitening effect in the existing liquid fluorescent whitening agent for whitening soap. In the present invention, the water-soluble whitening agent dye I and the water-soluble whitening agent dye II are prepared into a transparent mixed liquid whitening agent through a certain process under the dispersion and solubilization of other materials. This product combines the characteristics of the excellent whitening performance of the brightener dye Ⅰ on the fabric and the excellent whitening performance of the whitening agent dye Ⅱ on the substrate. It not only improves the comprehensive decontamination performance of the whitening soap, but also improves the appearance of the whitening soap. BaiDu. The product is in liquid dosage form and can be directly used in the processing and production of whitening soap, which not only simplifies the operation process, but also reduces the environmental pollution caused by dust, and is also conducive to automatic feeding.

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...
