Abstract

Provided are aqueous hard surface cleaning and disinfecting composition which comprises the following constituents: (a) at lease one cationic surfactant having germicidal properties; and (b) a fluorosurfactant selected from the group of nonionic fluorosurfactant, cationic fluorosurfactant, and mixtures thereof, and (c) a film-forming, organosilicone quaternary ammonium compound. Optionally the compositions may further include (d) one or more detersive surfactants particularly selected from carboxylate surfactants, as well as nonionic, cationic and amphoteric surfactants, (e) one or more organic solvents, and further conventional additives.

The compositions provide good sanitization of hard surfaces, and good cleaning notwithstanding the surprisingly low amount of fluorosurfactant present.

Claims

1. A hard surface cleaning and disinfecting composition which comprises:

(a) 0.001%-10% wt. of at least one cationic surfactant having germicidal properties;

(b) 0.001-5% wt. of a fluorosurfactant having the formula;

space="preserve" listing-type="equation">C.sub.n F.sub.2n+1 SO.sub.2 N(C.sub.2 H.sub.5)(CH.sub.2 CH.sub.2 O).sub.x CH.sub.3

where n has a value of from 4 to 12 and x has a value of from 4 to 18;

(c) a film forming, organosilicone quatemary ammonium compound;

(d) optionally, one or more detersive surfactants;

(e) optionally, one or more organic solvents;

(f) water; and

(g) optionally, one or more further conventional optional constituents selected from;

pH buffering agents, perfumes, perfume carriers, colorants, hydrotropes, viscosity modifying agents, further germicides, fungicides, anti-oxidants, and anti-corrosion agents.

2. The hard surface cleaning and disinfecting compositions according to claim 1 which is characterized as containing (d) one or more detersive surfactants selected from carboxylate surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, and mixtures thereof.

3. The hard surface cleaning and disinfecting compositions according to claim 1 which is characterized in that (d), one or more detersive surfactants are not included.

4. The hard surface cleaning and disinfecting compositions according to claim 1 which is characterized in that (e), one or more organic solvents are not included.

5. The hard surface cleaning and disinfecting compositions according to claim 1 which is characterized, in that (d), one or more detersive surfactants and (e) one or more organic solvents are not included.

6. The hard surface cleaning and disinfecting compositions according to claim 1 which is characterized as containing:

(d) one or more detersive surfactants selected from carboxylate surfactants, nonionic surfactants, cationic-surfactants, amphoteric surfactants, and mixtures thereof;

as well as
