US 2026/0000073 A1 · ANTIMICROBIAL COMPOSITIONS WITH LOW CORROSIVITY AND TOXICITY AND THE USE THEREOF

Abstract

The disclosure relates to compositions, including ready-to-use spray or wipe compositions, that are non-toxic, non-corrosive, biodegradable acidic antimicrobial compositions that exhibit broad-spectrum antimicrobial efficacy, wherein the compositions comprise an amine oxide, such as an alkyl amine oxide, in combination with an acidulant. Beneficially, the acidic antimicrobial compositions are capable of achieving at least a 3-log microbial reduction within 5 minutes under relatively mild pH conditions. The compositions provide cleaning and sanitizing.

Dependent claims

A method of use for providing surface cleaning, sanitizing and/or disinfecting comprising:

(a) contacting a surface in need of cleaning, sanitizing and/or disinfecting with an acidic antimicrobial composition comprising:
(i) an alkyl amine oxide according to the structure:
wherein R1, R2, and R3 are independently selected from saturated or unsaturated and straight or branched alkyl groups or aromatic groups having from 1-24 carbons;
(ii) an acidulant comprising an inorganic acid, organic acid, or a combination thereof;
(iii) optionally a drying agent comprising an alcohol;
and
(iv) water;
(b) wherein the acidic antimicrobial composition achieves at least a 1-log microbial reduction or at least a 3-log microbial reduction in 5 minutes or less in an in vitro assay;
wherein the pH of the use solution of the acidic antimicrobial composition is between about 3.5 to about 5.5, or wherein the pH of the RTU acidic antimicrobial composition is between about 4 to about 5.5.

6 more elements

A concentrate or ready-to-use (RTU) acidic antimicrobial composition comprising:

(i) an alkyl amine oxide according to the structure:
wherein R1, R2, and R3 are independently selected from saturated or unsaturated and straight or branched alkyl groups or aromatic groups having from 1-24 carbons;
(ii) an acidulant comprising an inorganic acid, organic acid, or a combination thereof;
(iii) optionally a drying agent comprising an alcohol;
and
(iv) water,
wherein the pH of the concentrate composition is between about 3.5 to about 5.5, or wherein the pH of the RTU acidic antimicrobial composition is between about 4 to about 5.5, and
wherein the RTU acidic antimicrobial composition is optionally saturated on a wipe substrate.
