| Abstract: | The effectiveness of 11 non-phosphate containing powdered detergents and 12 phosphate containing powdered detergents, of varying formulations, in cleaning a standard soiled fabric in soft water (5 ppm) were evaluated. It was found that in soft water there were no differences between washing with either phosphate or non-phosphate detergent. In general, washing with detergents which contained phosphates did give somewhat better results in warm water. Detergents that contained bleach as an additive did not result in a whiter fabric. |
