AI Technical Summary

Technical Problem

Existing antibacterial compositions for treating inanimate surfaces are ineffective against non-envelope viruses and often leave residues or malodors, requiring high concentrations of antimicrobial agents.

Method used

A norin freshening composition comprising at least 85% water, carboxylic acids, citric acid salts, and a mixture of first and second antimicrobial agents, formulated at a pH of 3-6, which effectively reduces bacterial and viral activity on inanimate surfaces without leaving residues or malodors.

Benefits of technology

The composition provides improved freshness and antimicrobial effects on inanimate surfaces, effectively reducing viral and bacterial activity while minimizing residues and malodors, even at low concentrations of antimicrobial agents.

Abstract

A no-rinse freshening composition for treating an inanimate surface or item. The freshening composition comprises: a) at least 85% water by weight of the freshening composition; b) a carboxylic acid; c) a salt of citric acid; d) a mixture of a first and a second antimicrobial agent, each of the first and second antimicrobial agents being represented by formula (I): [Formula 1] TIFF2024527516000013.tif27128 (in the formula, R 1 is a linear or branched C1-C4 alkyl group, R 2 is a linear or branched C1 to C20 alkyl, benzyl or alkylbenzyl; R 3 is a linear or branched C6 to C20 alkyl, benzyl or alkylbenzyl; R 4 is a linear or branched C1-C4 alkyl group, X is an anion, The composition has an undiluted pH of 3 to 6 at room temperature, and a weight ratio of the total amount of carboxylic acid and citric acid salts to the mixture of the first and second antimicrobial agents is 1:1 to 10:1.
