  • Patent number: 5380453
    Abstract: A composition for removing ink from a printing machine, which composition comprises 50-99.75% by weight of a C.sub.1 -C.sub.5 alkyl ester of an aliphatic C.sub.8 -C.sub.22 monocarboxylic acid and mixtures thereof; and 0.25-10% by weight oil in water emulsifier. The composition preferably comprises less than 19 weight percent of combined alkanes, alkenes and C.sub.1 -C.sub.10 alkyl esters of fatty acids having 18 carbon atoms or less. The composition may contain vegetable oil in an amount of up to 15% by weight.The invention further comprises an emulsion for removing ink from a printing machine which comprises the forgoing composition emulsified in water in such amount that the water phase comprises up to 50% by weight of the emulsion, and combined emulsifier in an amount of 0.5-10% by weight of emulsion, at least 50% of said combined emulsifier being an oil in water emulsifier.

  • Patent number: 5143639
    Abstract: Use of (C.sub.1 -C.sub.5) alkyl esters of aliphatic (C.sub.8 -C.sub.22) monocarboxylic acids for removing fat, inks and the like from printing apparatus, in particular from offset printing machines, and a cleaning agent for this, containing as its main component a (C.sub.1 -C.sub.5) alkyl ester of an aliphatic (C.sub.8 -C.sub.22) monocarboxylic acid or a mixture of such esters.The most suitable esters are methyl, ethyl or isopropyl esters or mixtures thereof, and particularly expedient is an ester mixture obtained by interesterification of an oleic acid containing oil or by esterification of an acid mixture having a corresponding composition.The ester or ester mixture may be admixed with up to 50% by weight of vegetable oil.Further, the ester or ester mixture or the mixture thereof with vegetable oil may be emulgated in water in such amount that the water phase comprises up to 50%, preferably 25-35% by weight of the emulsion using an emulsifier in an amount of 1-10%, preferably 3-5% by weight of the emulsion.
