A test to measure the caking tendency of dried detergents is described. This test has good reproducibility and should be useful in screening new products, studying formulation changes and examing anticaking agents. The test measures the force necessary to break cylinders formed from test detergents. Forming and breaking forces are extremely critical and are provided by an Instron Universal Tester. The sensitivity of the test demands careful control of the environment; a number of critical factors are discussed. These include test procedure variables such as cylinder length, forming force, forming rate and the time to form the cylinder and product variables such as moisture content and particle size. An increase in the forming force and time, particle size within cer-tain limits and moisture, increase the breaking force. Results on drum-dried products were found to correlate poorly with spray-dried products. Heavy duty products show a lower caking tend-ency than do light duty products. Anticaking additives cause a very marked decrease in break-ing force. |
