Abstract
An antiseptic composition comprising a multivalent cationic antiseptic present in an amount of 0.05 to 0.5 percent based upon the ready to use composition; an anionic compound which is water soluble in an amount of at least 0.1 grams in 100 grams water at 23 deg C., wherein the anionic compound is present at a concentration which would result in precipitation of the multivalent cationic antiseptic in the composition without a solubilizing surfactant present; wherein the composition, with the antiseptic, surfactant and anionic compound combined with each other, is free of precipitate.
Claims9
An antiseptic composition comprising:
- a multivalent cationic antiseptic selected from the group consisting of chlorhexidine acetate, chlorhexidine gluconate, chlorhexidine lactate, chlorhexidine methosulfate, and polyhexamethylene biguanide hydrochloride, and a combination thereof,
- wherein the multivalent cationic antiseptic is present in an amount of 0.05 to 0.5 percent based upon the weight of the antiseptic composition;
- an anionic compound selected from sodium carboxymethyl cellulose, sodium saccharin, sodium phosphate, sodium bicarbonate, and a combination thereof,
- wherein the anionic compound is present in an amount of at least 0.05 percent based the weight of the antiseptic composition;
- and
- a solubilizing surfactant selected from the group consisting of zwitterionic surfactants, amine oxide surfactants, micelle-forming nonionic surfactants, and a combination thereof;
- wherein the solubilizing surfactant is present in an amount greater than 80 wt-%, the anionic compound is present in an amount of less than 20 wt-%, and the multivalent cationic antiseptic is present in an amount of not more than 10 wt-%, wherein wt % is based upon the total weight of the combination of solubilizing surfactant, the anionic compound, and the multivalent cationic antiseptic, and
- wherein the antimicrobial composition is free of precipitate according to Test Method A.
