A composition that includes an activatable aggregate is described herein. The aggregate has a core and a shell. In some embodiments, when the aggregate is exposed to acoustic energy, the core of the aggregate includes a hydrogel that is capable of absorbing a relatively large amount of water. The core of the aggregate is covalently bound to a shell of linear aliphatic moieties. The aggregate is synthesized to minimize the amount of water in the core, prior to exposure to acoustic energy. Methods of hydrating using the compositions are also provided.

A skin care composition in the form of a water-in-oil, high internal phase emulsion that provides an improved sensory experience when applied to keratinous tissue. The thick, creamy consistency of the emulsion provides a moisturization signal to the consumer, but the shear thinning behavior of the high internal phase emulsion in combination with the superabsorbent polymer in the internal aqueous phase provide a light, cool, silky feel. The composition includes a non-thickening, superabsorbent polymer in the aqueous phase, but does not form visible beads of water when applied to skin.

Compositions of the present invention include an anionic surfactant, a zwitterionic surfactant, a superhydrophilic amphiphilic copolymer, an organic acid; and a polymer selected from the group consisting of a non-hydrophobically modified alkali-swellable emulsion polymer and a non-crosslinked hydrophobically modified acid-swellable emulsion polymer, wherein, when the composition contains the non-hydrophobically modified alkali-swellable emulsion polymer, the non-hydrophobically modified alkali-swellable emulsion polymer is present in an amount of about 0.1% to 5% by weight, and when the composition contains the non-crosslinked hydrophobically modified acid-swellable emulsion polymer, the non-hydrophobically modified acid-swellable emulsion polymer is present in an amount of about 0.1% to 5% by weight, and wherein the composition has an NTU value of 95 or less, a yield value of about 0.1 Pascal or more and pH of from about 3 to about 6.5.

Polysaccharide alkali swellable rheology modifiers include an emulsion polymer including at least one polysaccharide portion and at least one synthetic portion wherein the at least one synthetic portion is obtained from at least one anionic ethylenically unsaturated monomer, at least one nonionic ethylenically unsaturated monomer or a combination thereof, wherein at least one of the nonionic ethylenically unsaturated monomers is a hydrophobic ethylenically unsaturated monomer, as well as methods of making polysaccharide alkali swellable rheology modifiers.
