The invention relates to mixtures composed of dialkylphosphinic esters and of further components, which comprise A) from 98 to 100% by weight of monocarboxy-functionalized dialkylphosphinic esters of the formula (I) in which R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB>, R<SUB>4</SUB>, R<SUB>5</SUB>, R<SUB>6</SUB>, and R<SUB>7 </SUB>are identical or different and, independently of one another, are H, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, and/or phenyl, Y is methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, phenyl, 2-hydroxyethyl, 2,3-dihydroxypropyl, 2-hydroxypropyl, 3-hydroxypropyl, 4-hydroxybutyl, 3-hydroxybutyl, 2-hydroxybutyl, and/or 6-hydroxyhexyl, allyl, and/or glycerol, X is H, Li, Na, K or NH<SUB>4</SUB>, or X is defined as for Y, and then X and Y are two identical radicals or two different radicals of the above organic radicals, and B) from 0 to 2% by weight of halogens, where the entirety of the components always amounts to 100% by weight.
