FIELD: unitary products.

SUBSTANCE: invention relates to a unitary product based on a detergent for washing. Described is a unitary article containing two or more non-fibrous plates and discrete particles located between the specified two or more non-fibrous plates, and both of the specified non-fibrous plates and the specified discrete particles are water-soluble; wherein each of said non-fibrous plates contains at least one film-forming agent and a first surfactant, said first surfactant being selected from the group consisting of non-alkoxylated linear or branched C₆-C₂₀ alkyl sulfates (AS), linear C₆-C₂₀ alkylbenzenesulfonates (LAS) and combinations thereof, wherein said first surfactant has a hydrophilic index (HI) of not more than 7.5; wherein each of said discrete particles contains a second surfactant, said second surfactant being selected from the group consisting of linear or branched C₆-C₂₀ alkyl alkoxylated sulfates (AAS) having a weight average degree of alkoxylation in the range from 0.1 to 10, C₆-C₂₀ alkyl alkoxylated alcohols (AA) having a weighted average degree of alkoxylation ranging from 5 to 15, and combinations thereof, wherein said second surfactant has an HI greater than 7.5.

EFFECT: invention is aimed at providing plate-like laundry detergent-based products with greater freedom in surfactant selection and corresponding improved cleaning performance from common soil, while maintaining processing stability and other desirable attributes of existing plate-like laundry detergent-based products such as fast dissolution and little or no caking.
