The 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 o f at least two chemically and/or physically different particulate materials of specified particles sizes. The inclusion of materials having a therapeutic benefit on the teeth or gums in the agglomerates such as zinc citrate provid es 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 small er particles, thus giving the consumer the feeling of initial cleaning and subsequent polishing.
