The object of the present invention is to provide a lubricant for refrigerators having good compatibility with chlorine-free Flon-type coolants, good lubricity and resistant to hygroscopicity and a composition for refrigerators using this lubricant.This lubricant contains a monomethylether of polyoxyethyleneoxypropyleneglycol where the end group at the hydrogen terminal is an oxyethylene group, represented by the following general formula (1):wherein the AO group represents oxypropylene group, or copolymeric group of oxypropylene groups and oxyethylene groups wherein the copolymeric form may be a block type and/or a random type, m is a number of 1<=m<=50, n is a number of 1<=n<=10, and the content of the oxyethylene group in the compound ranges from 5 to 60 percent by weight. A composition for refrigerators using said lubricant is also provided.
