Abstract: The present invention provides an oral care composition comprising, by total weight of the composition: (a) 15 to 35 weight % calcium carbonate; (b) 0.5 to 2 weight % cellulose ether thickening agent; (c) 1 to 6 weight % clay thickening agent; and (d) at least 35 weight % water; wherein, when the composition comprises less than 28 weight % calcium carbonate and less than 4 weight % clay thickening agent, the cellulose ether thickening agent is present in an amount of greater than 1 weight %.

Abstract: The present invention provides an oral care composition comprising, based on the total weight of the composition: (a) 15 to 24 weight % calcium carbonate; (b) 0.9 to 2.5 weight % cellulose ether thickening agent; (c) 7 to 10 weight % thickening silica; and (d) at least 40 weight % water.

Abstract: A refill dispensing bottle (1), comprising: a container (200) defining a chamber (220) storing a viscous flowable substance and having an opening (240) through which the substance is dispensable from the chamber; and a dispenser (100) comprising a seal (110) sealing the opening, a substance flow passageway fluidly connecting the chamber to an exterior of the container through the seal, and a vent (130) fluidly connecting the chamber to the exterior of the container through the seal in parallel with the substance flow passageway; wherein a cross-sectional area of the substance flow passageway, a cross-sectional area of the vent, and a viscosity of the substance are selected so that the substance at room temperature and atmospheric pressure is dispensed from the substance flow passageway at a rate of less than 35 cc/sec and at least 0.5 cc/sec with the bottle inverted and the vent unblocked.

Abstract: A multicomponent composition separating surfactant and fragrance into separate phases to increase the fragrance release from the composition.

Abstract: A process that degasses a structured surfactant composition that comprises at least one surfactant, water, and at least one suspending agent chosen from polysaccharides, gums, and celluloses. By degassing the composition, the suspending agent can form a structured system. Gas, such as air bubbles, disrupts the formation of the structuring system, which reduces the ability of the composition to suspend materials.

Abstract: A surface treated magnetic pigment particle suitable for use with a binder in an information-recording layer of magnetic recording media. The surface treated magnetic pigment particle is a magnetic pigment particle with at least first and second surface treatment agents adsorbed onto the surface of the magnetic pigment particle. The first surface treatment agent has the formula E—X1—A1 wherein E is an electron withdrawing group which is not reactive with the binder, A1 is an acidic group, and X1 is a divalent moiety. The second surface treatment agent has the formula F—X2—A2 wherein F is a functional group reactive with the binder, A2 is an acidic group, and X2 is a divalent C1-4 alkyl moiety.
