Laundry detergent composition
An article is provided including an aqueous liquid detergent, and a package for the aqueous liquid detergent which is in direct contact with the aqueous liquid detergent, wherein the package is formed from a water-soluble, film-forming material. The aqueous liquid detergent includes at least about 40% by weight of water based on the total weight of the aqueous liquid detergent, a builder comprising potassium carbonate, wherein the potassium carbonate is present in an amount of at least about 25 weight percent, based on the total weight of the aqueous liquid detergent, a first surfactant, wherein the first surfactant is an anionic surfactant, and a second surfactant, wherein the second surfactant is a nonionic or an amphoteric surfactant. The first surfactant and the second surfactant are present in a combined total amount of about 0.1% to about 25% percent by weight based on the total weight of the aqueous liquid detergent.
1 . An article comprising:
an aqueous liquid detergent; and
a package for the aqueous liquid detergent which is in direct contact with the aqueous liquid detergent, wherein the package is formed from a water-soluble, film-forming material;
wherein the aqueous liquid detergent is homogenous and comprises:
at least about 40% by weight of water based on the total weight of the aqueous liquid detergent;
potassium carbonate in an amount of at least 30 weight percent, based on the total weight of the aqueous liquid detergent;
at least one enzyme stable at an alkaline pH;
an anionic surfactant; and
a nonionic surfactant;
wherein a total amount of surfactant in the aqueous liquid detergent is about 0.1% to about 25% percent by weight based on the total weight of the aqueous liquid detergent, and
wherein a weight ratio of the nonionic surfactant to the anionic surfactant on a percent actives basis is about 90:10 to about 75:25.
2 . The article of claim 1 , wherein the water is present in an amount of about 50 to about 65 weight percent, based on the total weight of the aqueous liquid detergent.
3 . The article of claim 1 , wherein the aqueous liquid detergent further comprises at least one enzyme stabilizer.

6 . The article of claim 1 , wherein the aqueous liquid detergent further comprises a third surfactant, wherein the third surfactant is a nonionic or an amphoteric surfactant.
7 . The article of claim 1 , wherein the water-soluble film-forming material is polyvinyl alcohol.
8 . The article of claim 1 , wherein the anionic surfactant is an alkyl ether sulfate.
9 . The article of claim 1 , wherein the nonionic surfactant is an alkylpolyglucoside.
10 . The article of claim 1 , wherein the aqueous liquid detergent remains homogenous and the package remains intact following at least 7 cycles of 50° C.-RT, wherein each cycle of the at least 7 cycles of 50° C.-RT comprises holding the article at a temperature of about 50° C. for about 12-24 hours and cooling the article to room temperature before starting another cycle.
11 . The article of claim 1 , wherein the aqueous liquid detergent has a pH of greater than 10.6.
12 . The article of claim 1 , wherein the at least one enzyme comprises a protease enzyme.
13 . The article of claim 1 , wherein the aqueous liquid detergent excludes sodium carbonate.
14 . The article of claim 1 , wherein the aqueous liquid detergent remains homogenous and the package remains intact for a time period of at least 3 months at a temperature of about 40° C.
