Abstract: An aqueous lubricant emulsion for medical or food apparatus, comprising: (a) 5 wt % to 30 wt % of a mineral oil; (b) 5 wt % to 30 wt % of an emulsifier system consisting of two emulsifiers selected from the group consisting of sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, oleyl alcohol ether, triethanolamine oleate, wherein the mass ratio of the two emulsifiers is in a range of 2:8 to 8:2; (c) 0.5 wt % to 5 wt % of one or more coemulsifiers selected from the group consisting of fatty alcohols, long-chain fatty acids, and diisooctyl succinate sulfonates; and (d) the balance of water. A method for washing medical or food apparatus including the step of subjecting the medical or food apparatus to a treatment using the lubricant emulsion according to the invention after a washing step for the medical or food apparatus is also described.
