Abstract of the Disclosure Emulsifiers for metal processing oils which substanti- ally comprise 30 to 50 weight % of a chlorinated paraffin sulfon- ate in admixture with a partially chlorinated paraffin; 15 to 30 weight % of reaction products obtained by converting sulfochlor- ides of alkylaromatic, cycloaliphatic, alkylcycloaliphatic or, preferably, aliphatic hydrocarbons having a total of 12 to 24 carbon atoms to the corresponding alkylsulfonamides with the use of ammonia or primary lower aliphatic amines and subsequently reacting these alkylsulfonamides with halocarboxylic acids having from 2 to 22 carbon atoms in the presence of alkalis, or by re- acting the above sulfochloides with aminocarboxylic acids having from 2 to 11 carbon atoms in the presence of alkalis; the reaction products optionally being converted subsequently to the sodium, potassium, mono-, di- or trialkanolamine salts, morpholine salts or cyclohexylamine salts; 15 to 20 weight % of a surface-active compound of the formula R(CH2CH2O)nH in which n is an integer of from 3 to 12 and R is C10-C22- alkanoyloxy or -alkenoyloxy, C8-C22-alkoxy or -alkenoxy, C6-C16-alkylphenyl or -alkylnaphthyl, or mono-, di- or tri-C8-C22-alkyl- or -alkenylamine; and 15 to 25 weight % of a reaction product of mono- or diethanolamine with a saturated or unsaturated aliphatic carboxylic acid having from 12 to 20 carbon atoms.
