Claims
- 1. In a washing, rinsing or cleansing agent containing an alkali aluminum silicate and a detergent, the improvement comprising employing as said silicate the hydrophilic alkali aluminum silicate prepared by the process comprising mixing a crystalline ion exchanging alkali metal aluminum silicate with a hydrophilic material which is ortho phosphoric acid, an alkali metal ortho phosphate, pentasodium tripolyphosphate, tartaric acid, an alkali metal tartrate or pentaerythritol in the presence of water, said hydrophilic material being employed in an amount sufficient to impart hydrophilicity to the alkali metal aluminum silicate but not over 30% of the weight of the silicate, drying and subsequently grinding the treated silicate to a particle size of not over 100 microns.
- 2. A washing, rinsing or cleansing agent according to claim 1 wherein the hydrophilic material is an ortho phosphoric acid or an alkali metal ortho phosphate.
- 3. A washing, rinsing or cleansing agent according to claim 1 wherein the hydrophilic material is pentasodium tripolyphosphate.
- 4. A washing, rinsing or cleansing agent according to claim 1 wherein the hydrophilic material is tartaric acid or an alkali metal tartrate.
- 5. A washing, rinsing or cleansing agent according to claim 1 wherein the hydrophilic material is pentaerythritol.
- 6. In a washing, rinsing or cleansing agent, containing an alkali aluminum silicate and a detergent, the improvement comprising employing as said silicate the hydrophilic alkali aluminum silicate prepared by the process consisting of mixing a crystalline ion exchanging alkali metal aluminum silicate with a hydrophilic material which is ortho phosphoric acid, an alkali metal ortho phosphate, pentasodium tripolyphosphate, tartaric acid, an alkali metal tartrate or pentaerythritol in the presence of water, said hydrophilic material being employed in an amount sufficient to impart hydrophilicity to the alkali metal aluminum silicate but not over 30% of the weight of the silicate, drying and subsequently grinding the treated silicate to a particle size of not over 100 microns.
- 7. A washing, rinsing or cleansing agent according to claim 6 wherein the hydrophilic material is an ortho phosphoric acid or an alkali metal ortho phosphate.
- 8. A washing, rinsing or cleansing agent according to claim 6 wherein the hydrophilic material is pentasodium tripolyphosphate.
- 9. A washing, rinsing or cleansing agent according to claim 6 wherein the hydrophilic material is tartaric acid or an alkali metal tartrate.
- 10. A washing, rinsing or cleansing agent according to claim 6 wherein the hydrophilic material is pentaerythritol.
