Abstract
Abstract PCT No. PCT/AU85/00238 Sec. 371 Date May 23, 1986 Sec. 102(e) Date May 23, 1986 PCT Filed Sep. 24, 1985 PCT Pub. No. WO86/02090 PCT Pub. Date Apr. 10, 1986.Antiseptic cleansing compositions and in particular to those containing a water soluble salt of chlorhexidine (N,N'- bis (4-chlorophenyl)-3,12-diimino 2,4,11,13-tetrazatetradecanediimidamide) as its active antibacterial ingredient. The present invention provides an antibacterial composition comprising from 0.1% w/v to 10.0% w/v of a water soluble salt of chlorhexidine, at least one nonionic surfactant and a diluent or carrier, wherein the weight ratio of the chlorhexidine salt to the nonionic surfactant and an inert diluent or carrier, wherein the weight ratio of the chlorhexidine salt to the nonionic surfactant is not more than 1:7.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
122 words
An antibacterial composition comprising a water-soluble salt of chlorhexidine, a nonionic surfactant and an inert diluent or carrier wherein the nonionic surfactant is at least one compound having the formula R--O--(--CH.sub.2 CH.sub.2 O--).sub.n H wherein R is the residue of an alkylphenol or a fatty alcohol and n is a number sufficiently high to assure water solubility between ambient temperatures and 45° C., the chlorhexidine salt being present at a concentration of from 0.1 to 10.0% w/v and the nonionic surfactant being present at a concentration of not greater than 25% w/v wherein the weight ratio of the chlorhexidine salt to the nonionic surfactant is not more than 1:7, and the composition does not contain a polyoxyethylene-polyoxypropylene condensate or an amphoteric surfactant.
Claim 2
Dependent Claim
122 words
An antibacterial composition comprising a water-soluble salt of chlorhexidine, a nonionic surfactant and an inert diluent or carrier wherein the nonionic surfactant is at least one compound having the formula R--O--(--CH.sub.2 CH.sub.2 O--).sub.n H wherein R is the residue of an alkylphenol or a fatty alcohol and n is a number sufficiently high to assure water solubility between ambient temperatures and 45° C., the chlorhexidine salt being present at a concentration of from 0.1 to 10.0% w/v and the nonionic surfactant being present at a concentration of not greater than 25% w/v wherein the weight ratio of the chlorhexidine salt to the nonionic surfactant is not more than 1:7, and the composition does not contain a polyoxyethylene-polyoxypropylene condensate or an amphoteric surfactant.
