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

The present invention relates to a nonwoven comprising a first layer comprising a first fiber and a second fiber, and a second layer comprising a third fiber; wherein the first fiber is hydrophobic and the second fiber is hydrophilic, and wherein the second layer is more hydrophilic than the first layer; a method for manufacturing the nonwoven according to the present invention; and an absorbent article comprising a topsheet; and a backsheet joined to the topsheet, wherein the topsheet comprises the nonwoven according to the present invention.

Nonwoven and absorbent articles having the same

A stable liquid detergent composition containing a self-structuring surfactant system. A liquid detergent composition that includes a linear alkyl benzene sulfonate, and a co-surfactant selected from a zwitterionic surfactant, an amphoteric surfactant, a branched non-ionic surfactant and mixture thereof, with a first viscosity of no less than 3000 mPa&#xb7;s measured at a first shear rate of 0.5 s, and a second viscosity of no more than 2,500 mPa&#xb7;s measured at a second shear rate of 20 s, and the ratio of the first viscosity to the second viscosity is no less than 3.

Stable liquid detergent composition containing a self-structuring surfactant system

A method of securing a layer of colloidal crystals to a substrate is provided, to enhance durability of an aesthetic effect provided by the colloidal crystals. The method involves depositing a layer of colloidal crystals formed of mono-dispersed particles on the substrate. Subsequently, a layer of water-borne coating is applied to the layer of colloidal crystals. To be effective, the water-borne coating should have a curing temperature that is less than the polymer glass transition temperature of the mono-dispersed particles forming the colloidal crystals. The water-borne coating penetrates through the colloidal crystals to the substrate thus retaining the colloidal crystals in place. The curing temperature of the water-borne coating ensures that the colloidal crystals are not damaged by the process for curing the coating.

Article with aesthetic substrate

Liquid laundry detergent compositions containing a microcapsule with a cationically charged coating and a fluorescent brightener with a distyrylbiphenyl unit, preferably Fluorescent Brightener-49, are provided. The compositions provide improved delivery efficiency of microcapsules and brightening of fabric whilst minimizing phase stability issues.

A blow-molded article having improved well-defined corners is provided.

Rigid articles having a well-defined corner

A stable liquid detergent composition containing a self-structuring surfactant system, where without using external structurants, the liquid detergent composition exhibits good shear thinning properties while maintaining stability under high shear. A liquid detergent composition that includes a linear alkyl benzene sulfonate, an amine oxide surfactant and little or no alkoxylated alkyl sulfate and unalkoxylated alkyl sulfate.

Liquid laundry detergent compositions containing a microcapsule with a cationically charged coating and a fluorescent brightener with a distyrylbiphenyl unit, preferably Fluorescent Brightener-49, are provided.
