Abstract of the Disclosure A method for producing a cooling emulsion, more particularly for use as a drilling, cutting and grinding aid in the metal-processing industry, whereby organic substances which are insoluble per se in water are rendered water-soluble and are emulsified with water, in the first place a mixture is produced which consists of about 3 to 15% by weight of natural wax(es) of animal and/or vegetable origin, 0.1 to 0.45% by weight: of a commerically available emulsifier, the remainder - about 50% by weight - being water, and an aqueous di/triethanol mixture consisting of about 37.5% by weight of diethanolamine(s) and about 12.5% by weight of triethanola- mine(s), the said mixture being then brought to the boil while being stirred, being cooled to a reaction-temperature, while being stirred, after the wax portion has been dissolved and, after amination of the said wax portion by the di/triethanol mixture, being cooled down to the temperature at which it is to be used.
