Abstract
Abstract A static storage stable fire resistant hydraulic fluid composition is provided which comprises (a) from about 40 to about 50 volume percent water together with (b) from about 50 to about 60 volume percent of a combination of (1) a lubricating oil (2) an emulsifier system containing succinic esters of hydrocarbon substituted succinic acid, polyhydric alcohols and alkaline earth salts of a fatty acid, and (3) at least one material selected from the group consisting of polyoxyethylene derivatives of alcohols and acids. Most preferred materials are the ether derivatives of polyoxyethylene containing from 10 to 20 oxyethylene units formed from 10 to 20 saturated carbon atom normal alcohols. The most preferred material is the ether derivative of a polyoxyethylene containing 10 oxyethylene units formed from stearyl alcohol.
