Abstract
This invention comprises a one-phase cosmetic composition which is a clear stick or gel having low tack. The cosmetic sticks are formed as a one phase system by combining: (a) from 0.5-50 weight percent of a dimethicone copolyol ester compound soluble in propylene glycol; (b) from 50-99 weight percent of a gellant/solvent system; which comprises a mixture of: (i) 0.5-4.0 weight percent dibenzylidene sorbitol; (ii) 0.05-1.0 weight percent of a co-gellant or structural integrity enhancer; (iii) 0.1-80 weight percent of a solvent selected from the group consisting of polyhydric alcohols for example, propylene glycol; dipropylene glycol; tripropylene glycol; tetrapropylene glycol; PPG-10 butane diol; 1,3-butane diol; 2-methyl-1,3-propanediol; PEG-6; and PPG-425; optionally including up to 50 percent of other solvents selected from the group consisting of propylene carbonate, diisopropyl sebacate, methyl pyrrolidone, and ethyl alcohol as a substitute for a portion of the polyhydric alcohol component; and (c) an effective amount of at least one cosmetically active ingredient, for example, an antiperspirant active.
