WATER-SOLUBLE ARTICLES WITH A SINGLE DOSE, MADE FROM A COMBINATION OF DIFFERENT FILMS AND CONTAINING COMPOSITIONS FOR HOUSEHOLD USE Russian patent published in 2020 - IPC C11D17/04 B65D65/46 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to sachets made from a combination of chemically different water-soluble films and containing compositions for domestic use, which are at least partially enclosed in water-soluble films in at least one compartment. Disclosed is a water-soluble article with a single dose, comprising at least one sealed compartment, at least one composition for washing, as well as a first water-soluble film containing an anionic PVA-copolymer and PVA-homopolymer in weight ratio of 30/70, and a second water-soluble film containing an anionic PVA-copolymer and PVA-homopolymer in weight ratio of 50/50. First film is sealed with second film to form at least one sealed compartment; wherein the first water-soluble film is chemically different from the second water-soluble film with respect to content of anionic monomer links. Difference between content of anionic monomer links in the first water-soluble film and content of anionic monomer links in the second water-soluble film ranges from approximately 0.05 mol% to approximately 4 mol%.

EFFECT: obtaining water-soluble articles with a single dose, having optimum solubility in water and reduced stickiness.
