Oral compositions
First Claim
1. An oral composition comprising agglomerates of particulate materials characterised in that the agglomerates are substantially free from organic and/or inorganic binding agents, said agglomerates having A) a particle size such that the D10 is equal to or bigger than 50 micrometer and the D90 is equal to or smaller than 2000 micrometer and having a D50 ranging from 80 micrometer to 1500 micrometer, said agglomerates being made up from at least two particulate materials in a relative weight ratio from 20:
- 80 to 80;
20, said materials being chemically and/or physically different from each other, whereby at least one particulate material has B) a particle size such that the D10 is equal to or bigger than 0.1 micrometer and the D90 is equal to or smaller than 80 micrometer and a D50 ranging from 4 to 35 micrometer, and C) at least one other particulate material has a particle size such that the D10 is equal to or bigger than 0.1 micrometer and the D90 is equal to or smaller than 100 micrometer and a D50 ranging from 9 to 70 micrometer, and upon use the gritty-feeling agglomerates will break-down into smaller particles, thus giving a consumer a feeling of initial cleaning and subsequent polishing.

Abstract
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 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.
