Abstract (en)

[origin: WO9105033A1] In the process described, a mixture containing an oil component, water and at least one emulsifier is emulsified at a temperature at which all of the components of the mixture are present in liquid form, and the emulsion formed is brought to a temperature in or above the phase-inversion temperature range of the emulsion; alternatively, the mixture is emulsified at a temperature in or above the phase-inversion temperature range, after which the emulsion is cooled to a temperature below this temperature range and is possibly diluted with water. This process is characterized in that the emulsion is formed by using a mixture having the following composition: a) 10 to 60% by weight of an oil component; b) 1 to 10% by weight of an emulsifying component consisting of at least one addition reaction product of 2 to 20 moles of ethylene oxide and fatty alcohols having 10 to 22 atoms of carbon; c) 1 to 10% by weight of a corrosion inhibitor, consisting of at least one carboxylic acid having the general formula (I): R-COOH (I), whereby R is a straight-chain or branched saturated or unsaturated alkyl residue with 6 to 22 atoms of carbon or a residue having the general formula (II) in which R<1>= a saturated, straight-chain or branched alkyl residue with 8 to 18 carbon atoms; d) 0 to 10% by weight of a co-emulsifier consisting of at least one fatty alcohol with 12 to 22 atoms of carbon; e) the balance being water.
