Abstract: The present invention describes a detergent composition in the form of a flexible sheet, which in turn is soluble in water, and the water-soluble detergent sheet. Said detergent composition in the form of a flexible sheet comprises a unique mixture of components, including: a water-soluble polymeric component, an anionic surfactant, a non-ionic surfactant, water and other components. Once mixed in the appropriate proportions, the components produce a flexible sheet with detergent characteristics that can be incorporated directly into a clothes-washing recipient, said recipient ranging from a simple bowl to an advanced automatic washing machine. Once the detergent sheet comes into contact with water inside the washing recipient, the sheet dissolves and releases the active ingredients and complementary ingredients contained therein.

Abstract: A water-soluble shopping bag and a preparation method thereof. The water-soluble shopping bag consists of the following components according to the following parts by weight: 100 parts of polyvinyl alcohol, 8-20 parts of a composite plasticizer; 10-30 parts of a polysaccharide and the derivative thereof; 1-5 parts of a processing aid, 0.1-0.5 parts of a film slipping agent and 0.5-3.0 parts of a film anti-blocking agent. The preparation method comprises the following steps: mixing the components according to the parts by weight, extruding the mixture to form pellets after mixing, then performing blow molding to form a film, and then preparing various types and sizes of water-soluble shopping bags. The water-soluble shopping bag has higher bearing capacity and cold water solubility, is suitable for use in water-free environment, and dissolves upon contacting water without producing pollution after being used.
