SUBJECT: Detergent Evaluation

The object of this research is to determine the rinsability differences between a new product SENSI-CLEAN and TIDE LIQUID. Attached is the Graph obtained from data of test results performed at the request of Mr. Charles Sutherland, Sutherland Products. These results were obtained from testing rinsability of 100% Cotton diapers during numerous wash cycles. Detergents supplied were SENSI-CLEAN 1(4 times recommended amount), SENSI-CLEAN(recommended amount), and TIDE. Also cyles were completed using Water only(Control), no detergent. All test were conducted utilizing the Launder-Ometer(Commercial Laundering). The Launder-Ometer rotates closed containers in a thermostatically controlled water bath at 40 rpm.

Three(3) fabric specimens were laundered in each of the detergents. Each Detergent was measured to insure ounce per ounce equivalency. Conditions during the wash cycle were determined from careful viewing of AATCC Test Method #61(Colorfastness to Laundering, Home and Commercial: Accelerated). Due to the need to stimulate the most stringent test the following procedure and condtions were followed.

1) TIDE LIQUID (Mfg. recommended amount)

2)SENSI-CLEAN 1(4 times Mfg. recommended amount)

3)SENSI-CLEAN (Mfg recommended amount)

4)WATER(Only) - (Control)

Each specimen was washed in a water bath, dried and conditioned at 70 degrees F. and 65% R.H. before original weight recorded. After the wash cycle each specimen was dried for 50 minutes., Cotton setting, to assure complete dryness before reweighing.

Wash Time - 45 mins./cycle   Detergent - 4 oz./spec.

Containers - 500ml.       Steel Balls - 100

Observing the graph you will not that cotton wash with Tide Liquid continued to gain weight while the Sensi-Clean (2 concentrations) and Waster only (control) weights remained basically unchanged. Thus making it safe to assume that Sensi-Clean has higher rinsability properties.
