The present invention provides a water-soluble laundry sheet comprising a detergent ingredient for laundry, a water-soluble film-forming polymer, and an alkali binder, wherein the laundry sheet comprises any one or more selected from the group consisting of polyols and metal ion chlorides. The present invention provides a water-soluble laundry sheet with enhanced formulation stability, storage stability, and sheet solubility.

Soluble laundry sheet comprising polyol or metal ion chloride

The present invention provides a laundry sheet wherein one or more component selected from a group consisting of a builder, an enzyme, a bleaching agent and a bleach activator is contained as a granule in a laundry film prepared using a laundry detergent component and a film-forming water-soluble polymer. The laundry sheet of the present invention completely dissolves in water and thus does not need to be removed after laundering. In addition, the laundry sheet of the present invention has superior cleaning performance, is convenient to use and has superior storage stability.

Laundry sheet comprising functional granules

The present invention provides a laundry sheet in which at least one laundry component is distributed inside a matrix formed from a water-soluble polymer, which is a polyvinyl alcohol or a polyvinyl alcohol-based polymer, and the laundry sheet has (i) a foamability of 0.5-0.9 (g/cm) or (ii) a drape stiffness of 3.5-7.5 cm.

Laundry sheet

The present invention provides a washing product comprising two or more sheets, which comprise a water-soluble polymer and have different dissolution rates in water, wherein each sheet contains i) washing detergent components, ii) washing softening components, iii) an aromatic agent, or iv) two or more thereof. Since two or more sheets have the different dissolution rates, in the present invention, the discharge time of the washing components contained in the sheets can be controlled, thereby having an excellent washing effect.
