Antibacterial compositions comprising quaternary ammonium germicides and alkamine oxides having reduced irritation potential

Abstract

Antibacterial compositions having antibacterial effectiveness and reduced eye irritation potential are disclosed. The antibacterial compositions contain a quaternary ammonium compound, an alkamine oxide, a nonionic compound, optional adjuvant materials known in the art, and water. The eye irritation is decreased by decreasing the amount, by weight, of alkamine oxide present in the composition and alternatively, or in combination therewith, increasing the ratio of nonionic material to alkamine oxide present in the composition.

AI Technical Summary

Benefits of technology

[0007]In accordance with an exemplary embodiment of the present invention, an antibacterial composition that exhibits reduced eye irritancy is provided. The antibacterial composition comprises a quaternary ammonium compound, an alkamine oxide, a nonionic material and water. The quaternary ammonium compound preferably is present in the amount of from about 0.1% to about 5.0% by weight of the composition. The alkamine oxide is preferably present in an amount of from about 0.1% to about 10% by weight of the composition. The nonionic material is preferably present in an amount from about 0.3% to about 1.5% by weight of the composition.

Problems solved by technology

One such agent, quaternary ammonium compounds, are effective cleansing agents, however, these compounds can cause irritation to the epithelial tissue of the user, particularly the skin and eye tissue.
