43-21(6924)A MOISTURIZED COMPOSITIONS OF HYDRATE-FORMING PHOSPHATES AND METHODS FOR PREPARATION THEREOF A composition of matter in particulate, crystalline form. The composition comprises a hydrate-forming phosphate selected from the group consisting of sodium tripolyphosphate, sodium pyrophosphate and trisodium phosphate, between about 0.1% by weight and about 23% by weight added water in the form of water of hydration said water ocntaining in solution sufficient surfactant to provide the composition from about 0.20 ppm and about 125 ppm of a surfactant. Methods for preparing such compositions are also disclosed. |
