回答: 为什么国内的洗衣粉多是固体，而美国的多是液体 由 leon001 于 2007-01-22, 18:39:28:
The same volume of liqid detergent can not make the same volume of powder detergent.
Nevertheless, the price of liqid detergent in USA is much more higher than the powder detergent in Germany, even though the EURO is a free-exchange currency.
