A high cleaning low abrasion dentifrice containing a silica hydrogel having a mean particle size from about 5 to about 11 microns; an Einlehner hardness of from 1 to about 20; an oil absorption of about 40 to less about 100 cc/g, a BET surface area from 100 to 700 m2/g of silica, the particles having a morphology characterized by glass conchoidal fracture surfaces whereby, the dentifrice composition has a RDA of 110 to 200 and a PCR from about 150 to about 300.

High cleaning dentifrice

Oral compositions, such as oral gels and toothpastes, containing a novel high cleaning, low abrasion silica hydrogel abrasive.

Dental abrasive

A storage stable oral composition having a pH of 8 or more which is effective against calculus, the composition containing an orally acceptable vehicle prepared using a sorbitol humectant containing less than about 0.10% by weight of a reducing sugar there being incorporated in the vehicle an effective anticalculus amount a water soluble alkali metal polyphosphate anticalculus salt.

Color stable anticalculus compostion

A catalytic process for the hydrolysis of alkyl vinyl ether/maleic anhydride copolymers, involving a base catalyst.

Process for hydrolyzing maleic anhydride copolymers

A method for the preparation of an aqueous stable premix containing a stannous ion releasing compound useful in the manufacture of an aqueous oral care composition containing a stable stannous ion releasing compound which comprises first dissolving the stannous compound in an aqueous solution of critic acid or its alkali metal salt to prepare the aqueous premix to the vehicle of the oral care composition.

Method of forming stable aqueous solutions of stannous compounds

A toothpaste or dental gel composition containing an amount of a synthetic linearly viscoelastic cross-linked polymeric thickening agent, especially a cross-linked methyl vinyl ether/maleic anhydride copolymer, effective to render the composition linearly viscoelastic, and a method of promoting oral hygiene by applying an effective amount of the composition to dental surface.

Viscoelastic dentifrice composition

Dental cream in contact with a polyolefin resin surface of a package such as a laminate tube, a mechanical dispenser or a flexible sachet. The dental cream contains a dentally acceptable water-insoluble alkaline earth metal salt, a liquid vehicle, a gelling agent and an additive which prevents syneresis. The liquid vehicle contains water, glycerine and sorbitol. The additive which prevents syneresis due to contact between the dental cream and the polyolefin resin is a nonionic block copolymer containing moieties of polyoxyethylene and polyoxypropylene.
