This provides a flexible and dissolvable solid sheet article containing a PVA polymer or copolymer having a weight average molecular weight of from 50,000 to 400,000 Daltons and a major surfactant selected from the group consisting of C-Clinear alkylbenzene sulfonates (LAS), alkoxylated sodium trideceth sulfates (STS), and combinations hereof.

Flexible and dissolvable solid sheet article

Flexible, dissolvable, porous solid sheet articles which include direct-added microcapsules therein for delivering a benefit agent and a process for making such solid sheet articles.

Flexible, porous, dissolvable solid sheet article containing direct-added microcapsules and process for making the same

This present invention provides dissolvable solid articles comprising multiple layers of flexible, dissolvable, porous sheets, in which a coating composition is present on at least one internal surface of at least one sheet in said solid articles. The present invention also provides a process for making such solid articles.

Multilayer dissolvable solid article containing coating composition and process for making the same

A method of making a non-fibrous laundry detergent sheet can include dispensing a microcapsule onto a precursor non-fibrous laundry detergent sheet, wherein the precursor non-fibrous laundry detergent sheet can include: (a) at least one surfactant; (b) at least one film former; and (c) a thickness ranging from 0.1 mm to 10 mm.

Laundry detergent sheet with microcapsules

This invention provides a multilayer dissolvable solid article, which comprises two or more flexible, dissolvable, porous sheets. Each of such two or more sheets is characterized by a Percent Open Cell Content of from about 80% to 100% and an Overall Average Pore Size of from about 100 μm to about 2000 μm and comprises a water-soluble polymer. At least two adjacent sheets in such dissolvable solid article are characterized by an Adhesion Score (AdS) of no less than 1, while the contacting surfaces of said at least two adjacent sheets are essentially free of adhesives. Preferably, the multilayer dissolvable solid article is essentially free of adhesives.

Multilayer dissolvable solid article and method of making same

A dissolvable solid article is provided, which is characterized by a multilayer structure formed of two or more flexible and dissolvable sheets that each comprises a water-soluble polymer. Such dissolvable solid article is at least 2 mm thick and contains one or more through-apertures or through-holes with a width or diameter of 0.2-0.8 mm.

Multilayer dissolvable solid article with apertures or holes

A dissolvable solid article which can include multiple layers of flexible, dissolvable, porous sheets, in which a coating composition including solid particles is present on at least one internal surface of at least one sheet and a process for making such solid articles.

Multilayer dissolvable solid article containing solid particles for making the same

This provides a flexible, porous, dissolvable solid sheet article having large pores on its top surface as well as a method of making the same.

Flexible, porous, dissolvable solid sheet articles having large pores and method of making same

This provides a flexible, porous, dissolvable solid sheet article containing a cationic surfactant.

Flexible, porous, dissolvable solid sheet articles containing cationic surfactant

A porous dissolvable solid can include an isethionate surfactant; a non-sulfate anionic surfactant; and an amphoteric surfactant, a zwitterionic surfactant, or a combination thereof.

Porous dissolvable solid structure

A unitary laundry detergent article that is completely or substantially water-soluble, which contains two or more non-fibrous, surfactant-containing sheets with one or more discrete, surfactant-containing particles located between such sheets. The non-fibrous sheets contain a first surfactant that is relatively less hydrophilic, while the discrete particles contain a second surfactant that is relatively more hydrophilic.

Unitary laundry detergent article

A water-soluble unitary laundry detergent article that contains two or more surfactant-containing non-fibrous sheets with a fabric hueing agent located between such non-fibrous sheets.

This invention relates to structured particles suitable for use in granular laundry detergent compositions, which contain an alkoxylated polyalkyleneimine in combination with a water-soluble alkali metal carbonate and silica and which contains little or no surfactant.

Structured particles comprising an alkoxylated polyalkyleneimine, and granular laundry detergent comprising the same

This invention relates to structured particles suitable for use in granular laundry detergent compositions, which contain an amphiphilic graft copolymer in combination with water-soluble alkali metal carbonate and sulfate particles and which contain little or no zeolite.
