Abstract:
A structured solid composition comprising at least one colorant, a liquid oil phase, and a gellant wherein the gellant is 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 being in the form of a solid; the composition being essentially free of hydrocarbon wax; and the colorant, the liquid oil phase and the ATPA resin forming a physiologically acceptable medium:
