Metal or metalloid salts ansolvo-acids and proton-, acids can be 80 complexed with 1,2,3-triols glycerol ethers, or glycerol thioethers containing at least 6 C atoms in the molecule that they are in the form of compositions which are soluble in organic solvents, especially non-polar aprotic, solvents, such as hydrocarbons. These stable compositions display an outstanding anti-static action and because of their, spectrum of properties are especially suitable for imparting, anti-static characteristics to polymers lubricants, fuels and, also solvents based on hydrocarbons.
