Abstract
Abstract A clear cosmetic stick is provided whose composition includes from about 10 to 90% of a polyhydric alcohol, from about 1 to about 40% of a soap, from about 1 to about 40% of an alkoxylate copolymer having the formula: [A-CH2CH2-A]f[(C2H4O)a(C3H6O)b(C2H4O)c(C3H6O)d]e[H]g wherein A is nitrogen; a, b, c and d are independently selected integers ranging from 0 to 200 with the proviso that the sum of a, b, c and d is at least about 50; e is an integer from 1 to 4; f is an integer from 0 to 1; g is an integer from 0 to 4; and a clarifying agent which is a basic amine present in an effective amount to maintain stick clarity.
