Abstract:
A structured composition comprising at least one liquid oil phase structured by at least one gellant, said at least one gellant comprising a tertiary amide-terminated polyamide resin (ATPA) of the formula (1): wherein, n designates a number of repeating units such that terminal amide groups constitute from 10% to 50% of the total amide groups; R1 at each occurrence is independently selected from a C1-22 hydrocarbon group; R2 at each occurrence is independently selected from a C2-42 hydrocarbon group; R3 at each occurrence is independently selected from an organic group containing at least two carbon atoms in addition to hydrogen atoms, and optionally containing one or more oxygen and nitrogen atoms; and R3a at each occurrence is independently selected from hydrogen, C1-10 alkyl and a direct bond to R3 or another R3a such that the N atom to which R3 and R3a are both bonded is part of a heterocyclic structure defined in part by R3aâ€”Nâ€”R3; the composition further comprising at least one amphiphile compound that is a liquid at ambient temperature or has a melting point below 35Â° C., and has an HLB value of less than 8.0.
