Aqueous oil-in-water emulsions of organic amines

An aqueous oil-in-water emulsion containing

• a) 1 to 5% by weight, based on the total weight of the emulsion, of an oil phase comprising at least one organic amine of the formula (I)
• R1—(NH—R2)n—NH2 (I)
• wherein
• n is 0, 1 or 2
• R1 is a linear or branched, acyclic hydrocarbon group having 12 to 22 carbon atoms;
• R2 is C2-C4-alkanediyl;
• b) and water,
• where the aqueous oil-in-water emulsion does not contain more than 2% by weight of organic ingredients, which are different from the amines of formula (I), based on total amount of organic components contained in the aqueous oil-in-water emulsion, and where the organic amine of formula (I) comprises at least 90% by weight, based on the total amount of the organic amine of formula (I) contained in the aqueous oil-in-water emulsion, of an organic amine of formula (I) with n being 1 or 2,
• where the aqueous emulsion has at least one of the following properties:
• P.1:
• the number average particle diameter of the droplets of the oil phase, as determined by light microscopy of at least 50 droplets is in the range of 1 to 11 μm,
• P.2:
• the instability index as defined by the ratio of observed clarification to maximum clarification, as determined by centrifugation for 390 seconds at a gravitational acceleration of 2.23 g and a temperature of 25° C. is at most 0.025.
