METHOD FOR EVALUATION AND STUDY OF SHAMPOOS 227 •n•s• R•OYA• wx•n o.•o• ol, AC•IVS Graph III • • eo so 3o oo some products gave negative re- sults. The extraction of the scoured wool, using the latter samples, yielded more than the original grease content found by petroleum ether extraction. A knowledge of the contents of these products would probably explain the unusual results obtained. CONCLUSIONS The need foi- a method for evalu- ating shampoos appears to be evi- dent. The B-P test method out- lined appears to give reproducible results and clearly evaluates sham- poos and detergents for effective- ness in removing grease from un- scou/-ed raw wool skeins. The com- mercial shampoos and detergents studied varied widely in their abil- ity to clean grease wool and the majority tested were surprisingly ineffective. It is suggested that detergents and soaps for shampoos be studied with this type of test to get a clearer and more accurate picture of their cleansing power. It must be realized that commercial shampoos must combine with cleans- ing power, a strong sudsing action, an easy rinsibility, a delicate and clean fragrance and perhaps most important it must leave the hair in a soft, manageable and lustrous condition.
