CONTROLLED BREAKDOWN GRANULES |
摘要 |
A granular composition for use in a personal care product comprises at least one water-insoluble inorganic material having a particle size of no more than 50 mu m and up to 10 per cent by weight based on weight of water-insoluble inorganic material of a non-binding swelling agent, the granules having a particle size greater than about 50 mu m and up to about 1000 mu m, as measured by sieve analysis, a dry strength such that from about 20 to about 70 per cent by weight pass through a 212 mu m sieve when subjected to the attrition test defined herein and a wet strength such that less than 12 per cent by weight residue remains on a 45 mu m sieve after ultrasonification in water for 1 minute with 48 mu m amplitude of vibration, and wherein said granules possess sufficient strength so as not to substantially break down when present in said personal care product.
