ANTIMICROBIAL LUBRICATING COMPOSITIONS. Antimicrobial lubricating compositions are disclosed. Lubricating antimicrobial compositions are particularly useful in providing medical devices with a wide range of antimicrobial capacity. The compositions include a lubricating oil. Representative lubricants may include polydimethyl siloxane, trifluoropropyl polysiloxane copolymer, and a dimethylsiloxane and trifluoropropylmethylsiloxane copolymer. The compositions include rheology modifiers as needed. The compositions also include antimicrobial reagents, which can be selected from a wide range of agents. Representative antimicrobial agents include aldehydes, anilides, biguanides, bis-phenols, quaternary ammonium compounds, cetyl pyridinium chloride, cetrimide, alexidine, chlorhexidine diacetate, benzalkonium chloride, and o-phthalaldehyde. |
