Cleaning compositions containing a crystalline builder material in selected particle size ranges for improved performance |
摘要 |
Cleaning compositions comprise a builder material which has substantially improved performance and is significantly less expensive than previous builders. The builder material has improved performance in that it unexpectedly has a high calcium ion exchange capacity and rate, and is easy to handle, process and disperse in washing solutions. The cleaning compositions contain a builder material having at least one crystalline microstructure including a carbonate anion, calcium cation and at least one water-soluble cation, wherein the builder has a particle size diameter within selected ranges for optimal performance. The microstructure should have a sufficient number of anions and cations so as to be "balanced" or "neutral" in charge.
