Dental cream in contact with a polyolefin resin surface of a package such as a laminate tube, a mechanical dispenser or flexible sachet comprises at least 20% by weight of a liquid vehicle comprising water, glycerine and sorbitol, the weight ratio of glycerine to sorbitol being 0.25:1 to 3:1, a solid vehicle comprising 0.05-10% by weight of gelling agent and 20-75% by weight of dentally acceptable water-insoluble polishing material, at least a major portion of which is alpha-alumina trihydrate and benzoic acid to reduce pH to 6-8.5 and prevent syneresis due to contact between the dental cream and the polyolefin resin. |
