Description

Technical Field

[0001] The invention relates to daily washing and care, in particular to a high-stability laundry condensate bead composition and a preparation method thereof. Background Art

[0002] Laundry detergent beads are a high-value product that is developing with the world's low-carbon economy and the gradual development of detergents towards low temperature, water saving and concentration. In recent years, with the rise of e-commerce platforms, laundry detergent beads are popular among online consumers because of their small size and portability, and are easy to carry and transport.

[0003] The laundry beads consist of two parts: a laundry beads composition and a water-soluble PVA coating wrapped on the outside. The use mechanism of the laundry beads is to dissolve the water-soluble packaging film to release the detergent. The water-soluble outer film has always been a key technical issue in the development of laundry beads. Since the water-soluble outer film is particularly sensitive to water, the moisture content in the laundry beads is controlled below 12%. Too much water will cause the film to soften, and too little water will cause the film to become hard and brittle. The market needs a laundry beads composition that ensures the stability of the outer film of the laundry beads and is not easy to break while controlling the water content; the present invention solves such a problem. Summary of the invention
