PCT No. PCT/EP95/03698 Sec. 371 Date May 13, 1997 Sec. 102(e) Date May 13, 1997 PCT Filed Sep. 20, 1995 PCT Pub. No. WO96/09034 PCT Pub. Date Mar. 28, 1996The invention relates to oral care products such as toothpastes with an improved sensorially-perceivable cleaning benefit. This is achieved by the inclusion in the oral care products of agglomerates, substantially free from organic and/or inorganic binding agents, whereby the agglomerates are made of at least two, chemically and/or physically different particulate materials of specified particle sizes. The inclusion of materials having a therapeutic benefit on the teeth or gums in the agglomerates such as zinc citrate provides for a further benefit in that this material is slowly released from the agglomerates, thus providing for a delivery of this material over a longer period. Upon use, the gritty-feeling agglomerates will break-down into smaller particles, thus giving the consumer the feeling of initial cleaning and subsequent polishing.
