Multi-layer laundry sheet

A water soluble laundry detergent product comprising one or more non-fibrous sheets and at least one solid layer,

• wherein the at least one solid layer comprises a gel and a solidifying agent and is coated on one or more sides of the one or more non-fibrous sheets, is disposed between two or more of the non-fibrous sheets, or a combination thereof,
• wherein the gel is present in an amount of from about 20% to about 80% by weight of the solid layer, and the solidifying agent is present in an amount of from about 20% to about 80% by weight of the solid layer,
• wherein the gel comprises about 15% to about 45% by weight of the gel of non-ionic surfactant and about 30% to about 55% by weight of the gel of anionic surfactant, and
• wherein the solidifying agent is solid at room temperature, has a melting point of about 50° C. or higher, and is water soluble.

A water soluble laundry detergent product comprising one or more non-fibrous sheets and at least one solid layer,

• wherein the at least one solid layer comprises a gel and one or more polyethylene glycols with a weight average molecular weight (g/mol) ranging from about 1000 to about 8000,
• wherein the at least one solid layer is coated on one or more sides of the one or more non-fibrous sheets, is disposed between two or more of the non-fibrous sheets, or a combination thereof,
• wherein the gel is present in an amount of from about 50% to about 80% by weight of the solid layer, and the one or more polyethylene glycols is present in an amount of from about 20% to about 50% by weight of the solid layer, and
• wherein the gel comprises about 15% to about 45% by weight of the gel of non-ionic surfactant and about 30% to about 55% by weight of the gel of anionic surfactant.

A process for preparing a water soluble laundry detergent product, comprising:

• a. mixing from about 20% to about 80% by weight of a gel with from about 20% to about 80% by weight of one or more polyethylene glycols to form a mixture;
• b. adding monoethanolamine to the mixture in an amount of about 3% to about 15% by weight of the gel to form a solid layer;
• and
• c. coating one or more sides of one or more non-fibrous sheets with the solid layer;
• wherein the gel comprises from about 15% to about 45% by weight of the gel of non-ionic surfactant and about 30% to about 55% by weight of the gel of anionic surfactant;
• and
• wherein the one or more polyethylene glycols have a weight average molecular weight (g/mol) ranging from about 1000 to about 8000.
