ANTIPERSPIRANT COMPOSITION AND MANUFACTURING METHOANTIPERSPIRANT COMPOSITION AND MANUFACTURING METHOD D

摘要

Disclosed is a stick or gel composition, which can be clear or translucent, for combatting body malodor (e.g., an antiperspirant composition). The composition contains an antiperspirant active material (e.g., an antiperspirant active metal salt, such as aluminum chlorohydrate) and a polyamide gelling agent, and also contains a solvent system for the antiperspirant active material and polyamide, which dissolves the gelling agent and from which the gelling agent can be gelled. The solvent system is glycol-free, and includes a non-ionic surfactant (e.g., laureth-4) and a polar solvent (including water)). Use of the glycol-free solvent system achieves a gelled composition that has reduced levels of tack (is substantially tack-free) and has cosmetically acceptable properties. The composition can further include an opaque wax (e.g., stearyl alcohol), especially where the composition includes relatively small amounts of polyamide gelling agent, to provide additional structure and enhance dissolution of the polyamide gelling agent, while achieving a translucent composition which produces an optically clear film when applied to the skin. The composition containing the non-ionic surfactant and opaque wax can be processed, to form the gelled composition, at relatively low temperatures (180 DEG -185 DEG F.).
