Abstract
The present invention provides compositions which not only effectively kill a broad spectrum of microorganisms present on surfaces on contact but continue to kill microorganisms for a period of time thereafter.
Claims19
A hard surface treatment composition providing a residual antimicrobial benefit to hard surfaces comprising:
- (a) at least one organic acid;
- (b) optionally, at least one anionic surfactant;
- (c) at least one polymer capable of forming a complex with (a) at least one of organic acid wherein the at least one polymer is selected from the group consisting of a copolymer of vinyl pyrrolidone/acrylic acid and its esters;
- and a copolymer of vinyl pyrrolidone/methacrylic acid and its esters copolymer;
- and
- (d) from 60% to 90% by weight of at least one organic solvent;
- (e) optionally, at least one propellant;
- (f) water;
- and
- optionally, one or more further conventional constituents selected from the group consisting of:
- pH buffering agents, perfumes, perfume carriers, colorants, hydrotropes, viscosity modifying agents, further germicides, fungicides, anti-oxidants, and anti-corrosion agents.
