This application pertains to antimicrobial medical gel compositions, the compositions comprising: (a) a gelling agent comprising etherified hydroxyethylcellulose; (b) an antimicrobial agent, specifically the quaternary ammonium compound benzalkonium chloride; (c) a solvent, propanediol being preferred; and (d) water. The compositions through their antimicrobial effectiveness address the problem of cross-contamination leading to infection, while meeting the criteria imposed upon medical gels used in ultrasound procedures which criteria include non-reflectiveness and non-refractiveness to ultrasound waves, pseudoplasticity, spreadability, adherence, acidity compatible with skin, minimal aeration, clarity, and resistance to drying. The medical gels function both as a lubricant and a couplant between a transducer and the skin, and find use in dermal ultrasound, physiotherapy, and medical aesthetic procedures. |
