Abstract

A teat dip formula is disclosed for use on dairy animals with the objective of reducing or preventing mastitis. The teat dip formula preferably includes up to about 2% of peracetic acid in solution made by mixing acetic acid, hydrogen peroxide, and from up to about 5% by weight of composition of a thickening agent. Other constituents of the formula may include effective amounts of a skin conditioning agent or agents, a surfactant or surfactants and urea. A method of preparing and applying the formula is disclosed.

Claims

An aqueous teat dip composition for use with dairy animals, comprising: acetic acid; hydrogen peroxide; and peracetic acid in an amout up to about 2% by weight of the composition.
The composition of claim 1, wherein the peracetic acid is produced via an in situ chemical reaction of acetic acid and hydrogen peroxide, and a sulfuric acid catalyst.
The composition of claim 1, and further comprising: a thickening agent in an amount up to about 5% by weight of composition.
The composition of claim 1, and further comprising a skin-conditioning agent in an amount up to about 75% by weight of composition.
The composition of claim 4, wherein the skin-conditioning agent comprises a moisturizer.
The composition of claim 4, wherein the skin-conditioning agent is glycerin.
The composition of claim 1, and further comprising: a surfactant in an amount up to about 2.0% by weight of composition.
The composition of claim 1, and further comprising urea in an amount up to about 1.0% by weight of composition.
The composition of claim 1, wherein the acetic acid is in an amount up to about 5.0% by weight of composition and the hydrogen peroxide is in an amount from about 0.1% to about 5.0% by weight of the composition.
The composition of claim 1, and further comprising up to about 5% of a thickening agent by weight of composition, and the thickening agent is selected from the group consisting of: polyvinyl pyrollidone, xanthan gum, guar gum, clay, methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, anionic carboxyvinyl polymers, hydroxymethylcellulose, and combinations thereof.
A method of preparing a peracetic teat dip composition, comprising the steps of: mixing acetic acid with hydrogen peroxide; and adding a thickening agent in an amount up to about 5% by weight of composition, and the thickening agent is selected from the group consisting of: polyvinyl pyrollidone, xanthan gum, guar gum, clay, N methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, anionic carboxyvinyl polymers, hydroxymethylcellulose, and combinations thereof.
The method of claim 11, wherein peracetic acid is produced via an in situ chemical reaction of acetic acid and hydrogen peroxide. 13. The method of claim 11, wherein the acetic acid is in an amount up to about 5.0% by weight of composition and the hydrogen peroxide is in an amount up to about 5.0% by weight of composition and the method further comprising the step of: adding water to form an aqueous solution. 14. The method of claim 11, wherein the step of adding a catalyst comprises: the step of adding sulfuric acid.
The method of claim 11, and further comprising the step of: adding glycerin in an amount up to about 75% by weight of the composition.
The method of claim 11, and further comprising the step of: adding surfactant in an amount up to about 2.0% by weight of the composition.
The method of claim 11, and further comprising the step of: adding urea in an amount up to about 1.0% by weight of the composition.
The method of claim 11, and further comprising the step of: adding up to about 5% by weight of composition of a thickening agent selected from the group consisting of: polyvinyl pyrollidone, xanthan gum, guar gum, clay, methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, anionic carboxyvinyl polymers, hydroxymethylcellulose, and combinations thereof. 19. A method of reducing mastitis in a dairy animal, comprising the step of: topically applying an antimicrobial composition to the teats of the animal, the composition comprising peracetic acid in an amount of about 2% by weight of the composition.
The method of claim 19, wherein the composition is prepared by a method comprising the step of: forming the peracetic acid in situ with a mixture of acetic acid and hydrogen peroxide.
The method of claim 20, wherein the peracetic acid is produced via an in situ chemical reaction of acetic acid and hydrogen peroxide in the presence of a catalyst.
The method according to claim 20, wherein the acetic acid is added in an amount up to about 5.0% by weight of the composition.
The method according to claim 20, wherein the hydrogen peroxide is added in an amount up to about 5.0% by weight of the composition. 24. The method according to claim 20, wherein the method of preparing the composition further comprises the step of: adding a skin conditioning agent in an amount of up to about 75% by weight of the composition.
The method according to claim 20, wherein the method of preparing the composition further comprises the step of: adding a surfactant in an amount of from about 0.2% to about 2.0% by weight of the composition.
The method according to claim 20, wherein the method of preparing the composition further comprises the step of: adding urea in an amount of up to about 1.0% by weight of the composition.
The method of claim 21, and further wherein the catalyst is sulfuric acid.
The method of claim 19, wherein the applying step is performed before milking of the animal. 29. The method of claim 19, wherein the applying step is performed after milking of the animal.
