A process for preparing an antimicrobial composition comprising
- combining (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof and (b) pelargonic acid, in an amount of the components (a) and (b) combined of at least 50 wt %, based on the total weight of all ingredients combined to prepare the composition, and in a ratio by weight of the antimicrobial agent (a) to the pelargonic acid (b) of from about 20:1 to about 1:2.5, and (c) an alkaline stabilizer in an amount of from about 0.2 wt % to about 25 wt %, based on the total weight of all ingredients combined to prepare the composition, wherein the alkaline stabilizer is in the form of an alkaline aqueous solution, and the composition has a pH of from about 5.0 to about 7.5.
An antimicrobial composition comprising
- (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof, and (b) pelargonic acid and/or a salt thereof, wherein the antimicrobial agent (a) and the pelargonic acid and/or salt thereof (b) are present in a combined amount of at least 50 wt %, based on the total weight of the composition, and the ratio by weight of the antimicrobial agent (a) to the pelargonic acid and/or salt thereof (b) is from about 20:1 to about 1:2.5, and
- (c) an alkylhydroxamic acid and/or a salt thereof in an amount no greater than 10 wt %, based on the total weight of the composition.
A personal care or home care product formulation comprising
- an antimicrobial effective amount of a combination of (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof, and (b) pelargonic acid and/or a salt thereof, and
- one or more additional ingredients suitable for use in a personal care or home care product formulation, wherein the ratio by weight of the antimicrobial agent (a) to the pelargonic acid and/or salt thereof (b) is from about 20:1 to about 1:2.5,
- the product formulation has a pH of at least 6.0, and
- the antimicrobial agent (a) constitutes no greater than 0.7 wt %, based on the total weight of the product formulation.
1 more element
A method of controlling microbial growth in or preserving a product formulation, comprising
- adding to the product formulation (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof, and (b) pelargonic acid and/or a salt thereof, wherein the antimicrobial agent (a) and the pelargonic acid and/or salt thereof (b) are present in the formulation in a combined antimicrobial effective amount,
- the ratio by weight of the antimicrobial agent (a) to the pelargonic acid and/or salt thereof (b) is from about 20:1 to about 1:2.5,
- the product formulation has a pH of at least 6.0, and
- the antimicrobial agent (a) constitutes no greater than 0.7 wt %, based on the total weight of the product formulation.
1 more element
A personal care or home care product formulation comprising
- an antimicrobial effective amount of from about 0.2 wt % to about 3 wt %, based on the total weight of the formulation, of a combination of (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof and (b) pelargonic acid and/or a salt thereof,
- (c) an alkylhydroxamic acid and/or a salt thereof, and
- one or more additional ingredients suitable for use in a personal care or home care formulation,
- wherein the ratio by weight of the antimicrobial agent (a) to the pelargonic acid and/or salt thereof (b) is from about 20:1 to about 1:2.5, and the ratio by weight of the combined amount of (a) and (b) to the amount of the alkylhydroxamic acid and/or salt thereof (c) is from about 5:1 to about 150:1.
1 more element
A method of controlling microbial growth in or preserving a product formulation, comprising
- adding to the product formulation (a) an antimicrobial agent selected from the group consisting of phenoxyethanol, benzyl alcohol and combinations thereof, (b) pelargonic acid and/or a salt thereof, and (c) an alkylhydroxamic acid and/or a salt thereof,
- wherein the antimicrobial agent (a) and the pelargonic acid and/or salt thereof (b) are present in the formulation in a combined antimicrobial effective amount of from about 0.2 wt % to about 3 wt %, based on the total weight of the formulation, and
- wherein the ratio by weight of the antimicrobial agent (a) to the pelargonic acid and/or salt thereof (b) is from about 20:1 to about 1:2.5, and the ratio by weight of the combined amount of (a) and (b) to the amount of the alkylhydroxamic acid and/or salt thereof (c) is from about 5:1 to about 150:1.
