Water-soluble unit dose article comprising an amphiphilic graft polymer and a carboxymethylcellulose

#The present disclosure relates to water-soluble unit dose articles containing amphiphilic graft polymer and carboxymethylcellulose and processes of washing fabrics using said water-soluble unit dose articles.

#Water-soluble unit dose articles are liked by consumers as they are convenient and efficient to use. Such water-soluble unit dose articles often comprise laundry detergent compositions.

#Consumers desire that following the laundry wash operation, their fabrics are clean and feel soft. It is well known that anionic surfactants provide softness to cotton fabrics especially terry towels and are even preferred over traditional alternative softening technologies given their lower compromise on water absorbency capacity of cotton fabrics. This property is especially desired for terry towels whose primary function is to absorb water after for example a consumer showering. Therefore, it is desired to maximize the amount of remaining anionic surfactants on terry towels following the wash operation to provide softness benefits.

#FIG. 1 is a water-soluble unit dose article according to the present invention.

#The present disclosure relates to a water-soluble unit dose article comprising a water-soluble film and a liquid laundry detergent composition. The water-soluble film and the liquid detergent composition are described in more detail below.

#The water-soluble unit dose article comprises the water-soluble film shaped such that the unit-dose article comprises at least one internal compartment surrounded by the water-soluble film. The unit dose article may comprise a first water-soluble film and a second water-soluble film sealed to one another such to define the internal compartment. The water-soluble unit dose article is constructed such that the detergent composition does not leak out of the compartment during storage. However, upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and releases the contents of the internal compartment into the wash liquor.

#The compartment should be understood as meaning a closed internal space within the unit dose article, which holds the detergent composition. During manufacture, a first water-soluble film may be shaped to comprise an open compartment into which the detergent composition is added. A second water-soluble film is then laid over the first film in such an orientation as to close the opening of the compartment. The first and second films are then sealed together along a seal region.
