A greasy frost-preventive composition which comprises (a) at least one member selected from among glycols, glycol ethers, polyalkylene glycols, polyalkylene glycol derivatives, glycerol, and glycerol derivatives, (b) at least one member selected from among soaps, urea compounds, particulate silica gel, lecithin, and polysaccharides, (c) at least one metal salt selected from among metal carboxylates, metal nitrates, metal phosphates, metal chlorides, and metal bromides, and (d) at least one member selected from among sorbitan fatty acid esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene alkyl ethers, castor oil, hardened castor oil, polyoxyalkylene castor oils, and polyoxyalkylene hardened castor oils in specified portions respectively.
