Abstract
Disclosed are clear, soap-gelled cosmetic (e.g., deodorant) stick compositions, containing alcohol and water, and including a combination of anionic (e.g., sodium laureth-13 carboxylate) and non-ionic (e.g., Ceteareth-55) surfactants as a clarifying agent. The non-ionic surfactants preferably include ethoxylated alcohols, and preferably have an HLB.gtoreq.24. The compositions can include various cosmetically active materials, including deodorant active materials (fragrance, Triclosan, etc.). The compositions have superior clarity and maintain superior clarity over extended periods of time, have improved (smoother) glide over the skin and a smoother surface, exhibit reduced syneresis in K-resin and polypropylene dispensing packages, and are easy to manufacture and have high gelling temperatures.
