  • the polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.
  • the group of polyhydroxy fatty acid amides also includes compounds of the formula (II) in the R is a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms
  • R 1 is a linear, branched or cyclic alkyl radical or an aryl radical having 2 to 8 carbon atoms
  • R 2 is a linear, branched or cyclic alkyl radical or an aryl radical or an oxyalkyl radical having from 1 to 8 carbon atoms, with C 1-4 alkyl or phenyl radicals being preferred
  • [Z] being a linear polyhydroxyalkyl radical whose alkyl chain is substituted by at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propoxylated Derivatives of this residue.
  • [Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose.
  • a reduced sugar for example glucose, fructose, maltose, lactose, galactose, mannose or xylose.
  • the N-alkoxy- or N-aryloxy-substituted compounds can then be converted into the desired polyhydroxy fatty acid amides according to the teaching of international application WO-A-95/07331 (Procter & Gamble) by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst.
  • Preferred fabric softeners contain, in addition to components a) and b), 0.1 to 5% by weight of one or more nonionic surfactants.
  • the agents were used in the final rinse cycle and the textiles treated with them were evaluated after drying by an expert panel of at least 5 persons with handle marks.
  • the handle scores as an average of at least 3 individual determinations, the classification between the two to be determined standards 0 (rinse with tap water) and 6 (textile equipped with 3 g distearyldimethylammonium chloride per kg of dry laundry) results.
  • the gripping marks of the compositions according to the invention and the comparative examples are shown in Table 2: Softness assessment [handles] V1 V2 V3 V4 E1 E2 E3 E4 E5 E6 E7 E8 E9 2.4 2.3 1.6 4.6 4.3 4.7 4.8 5.1 4.8 4.0 4.1 4.7
  • Table 2 shows that the agents of the invention, the pentaerythritol ester based comparison agents far surpass and the softness performance of conventional, Esterquat-based Reach or exceed softener (E5).
