preferable. The alkyl or alkenyl group is a straight chain
Or it may be any of branched chains. The average addition amount of ethylene oxide of component (a)
When the number of tools is 4 or less or 16 or more, the cleaning performance is insufficient.
It is not preferable because it becomes minutes. (A) Propile as an ingredient
If no oxide is added, the washing water at low temperatures
It is not preferable because the solubility is remarkably reduced.
When the average number of moles of added oxide is 4 or more, the biodegradability is remarkable.
It is not preferable because it deteriorates easily. (A) Non-ion of component
Surfactant is present in the liquid detergent composition of the present invention in an amount of 10 to 10.
60% by weight is suitable, and preferably 15 to
55% by weight. [0010] Used in the liquid detergent composition of the present invention.
