Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and more specifically, it relates to a concentrated laundry detergent containing BIO155 dispersing aid and a preparation method thereof. Background Art

[0002] With the continuous acceleration of the concentration level of the Chinese washing and care market, consumption upgrading, and the transformation of consumers' consumption concepts, concentrated laundry detergent beads products conform to the development trend of concentration in the washing industry. Concentrated laundry detergent beads products not only save energy during production, packaging, transportation, and storage, but also reduce the generation of waste. Concentrated laundry detergent beads products use quantitative packaging, dissolve immediately in water, have low foam and are easy to rinse, are convenient to use, and more meet the laundry needs of consumers, reducing waste caused by unreasonable pouring.

[0003] However, at the same time, concentrated laundry detergent beads also have some defects. Since concentrated laundry detergent beads are encapsulated with a polyvinyl alcohol water-soluble film, the polyvinyl alcohol water-soluble film is very easy to dissolve in water and is affected by air humidity. When stored in a high-humidity or long-term humid environment, concentrated laundry detergent beads often stick together and are not easy to separate. Forcibly separating them will cause the polyvinyl alcohol water-soluble film of the package to rupture, resulting in liquid leakage. In addition, if concentrated laundry detergent beads of different colors are placed together, color bleeding will occur during long-term storage, affecting the appearance of the product and reducing the user experience of consumers.

[0004] In the prior art, generally, powder is applied on the surface of the film. After applying powder on the surface of the water-soluble film, the fluidity of the film becomes better, and it is easy to be automatically packaged by a multi-dose machine. The powder applied on the surface of the film is generally starch. However, after a long time on the surface of the film, starch may become corrupt, causing an odor on the film, which affects the smell of the concentrated laundry detergent wrapped and the usability of the product.
