Abstract:
The invention provides a zinc-lysine complex having the formula [Zn(C 6 H 14 N 2 O 2 ) 2 Cl] + Cl ¯ having antibacterial and antiperspirant properties, together with personal care compositions comprising the complex, and methods of making and using these complexes and compositions. The application discloses a general reaction for formation of such complexes by mixing a Zn source with Lysine in 1:2 ratio: ZnO + 2 (Lysine 'HCI) - > [Zn(Lysine) 2 CI ] + CI - ⋅( H 2 O) 2
Abstract:
Disclosed herein are oral care compositions comprising a zinc amino acid halide. Methods of making and using the compositions are also provided.
Abstract:
The invention provides a personal care composition for application to the skin which comprises a personal care composition for application to the skin or hair comprising a zinc X halide and a cosmetically acceptable base, wherein X is an amino acid or trimethylglycine. Methods of making and using the compositions are also provided. The zinc X halide is can be used to deliver zinc salts to block perspiration and provide antibacterial effects.
