ABSTRACT:
Disclosed is a clear, crystal-free, soap-gelled cosmetic stick composition. The composition includes a soap gelling agent (e.g., sodium stearate); at least two aliphatic polyhydric alcohols that are solvents for the soap gelling agent and that have a relatively small molecular weight and a relatively large molecular weight (e.g., propylene glycol and dipropylene glycol), respectively; a propoxylated ether that is a further solvent for the soap gelling agent, such as a propoxylated butyl ether (e.g., PPG-14 butyl ether); water; and a clarifying agent. The clarifying agent is a mixture of (a) a propoxylated fatty alcohol, such as a propoxylated myristyl ether (e.g., PPG-3 myristyl ether), and (b) a water-soluble, N-substituted aliphatic fatty acid amide surfactant (e.g., a combination of cocamide DEA and cocoyl sarcosine). The stick composition has improved surface aesthetics and improved payout, and has less pullaway from the container. The disclosed cosmetic stick composition can be a vehicle for various active materials, such as deodorant active materials, sunscreens, etc., so as to provide a clear deodorant stick, a sunscreen stick, etc.
