Abstract:
A drycleaning method is disclosed. The method uses a composition comprising 30 to 90 wt. % of a dipropylene glycol C3-C4 alkyl ether, 5 to 65 wt. % of one or more C10-C15 hydrocarbons, and 1 to 10 wt. % of water. The method combines acceptable stain removal with faster-than-expected evaporability, particularly at the elevated temperatures used in commercial drycleaning.
