Composition comprising mixtures of glucamides, process for their preparation and their use

A composition melting at a temperature of at least 45° C. comprising:

• a) 20 to 84 wt.-% of a blend of N-hydrocarbon substituted-N-acylglucamides of the formula (I)
• wherein
• R1 is a linear or branched, alkyl group comprising 7 to 21 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl group comprising 7 to 21 carbon atoms,
• R2 is a linear or branched alkyl group or an aryl group,
• wherein the blend of N-hydrocarbon substituted-N-acylglucamides comprises:
• (a1) 3 to 35 wt.-% of at least one N hydrocarbon-N-acylglucamide of formula (I), wherein R1 is a linear or branched, alkyl group comprising 7 to 9 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl group comprising 7 to 9 carbon atoms,
• (a2) 15 to 75 wt.-% of at least one N-hydrocarbon-N-acylglucamide of formula (I), wherein R1 is a linear or branched, alkyl group comprising 11 to 13 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl group comprising 11 to 13 carbon atoms,
• (a3) 2 to 55 wt.-% of at least one N hydrocarbon-N-acylglucamide of formula (I), wherein R1 is a linear or branched, mono- or polyunsaturated alkenyl group comprising 11 to 17 carbon atoms, which are different from the N-hydrocarbon-N-acylglucamide(s) of components (a2) and (a4), and
• (a4) 2 to 12 wt.-% of at least one additional N-hydrocarbon-N-acylglucamide of formula (I) which is different from the N-hydrocarbon-N-acylglucamides of components (a1), (a2), and (a3),
• b) 15 to 50 wt.-% of water, and
• c) 1 to 30 wt.-% of at least one additive, wherein the total amount of components a) and c) is at least 50 wt.-%, and wherein the percentages refer to the total weight of the composition
