Abstract
Abstract A skin sanitizing composition is disclosed which is particularly suited as a teat dip or udder wash for dairy cows which comprises at least one phenyl alkanol such as benzyl or phenethyl alcohol as the microbiocidal or sanitizing ingredient in an amount effective to substantially reduce the bacteria population on a skin surface when the composition is applied thereto. An emulsifying amount of a surfactant is included to provide an aqueous dispersion of the phenyl alkanol ingredient, which enhances the germicidal activity of the microbiocidal or sanitizing ingredient. The composition may include an emollient if desired and has a typical pH of between about 4 and 7.

Claim 13
Independent Claim
74 words
A method of sanitizing the teat of a dairy cow comprising applying thereto an aqueous dispersion of a sanitizing mixture of benzyl alcohol and phenylethanol, in an amount effective to substantially reduce the bacteria population on said teat surface once said dispersion is applied thereto, said dispersion including an emulsifying amount of a surfactant to disperse said sanitizing mixture, said dispersion containing an emollient and having a pH of between about 4 and 7.
Claim 14
Independent Claim
74 words
A method of sanitizing the teat of a dairy cow comprising applying thereto an aqueous dispersion of a sanitizing mixture of benzyl alcohol and phenylethanol, in an amount effective to substantially reduce the bacteria population on said teat surface once said dispersion is applied thereto, said dispersion including an emulsifying amount of a surfactant to disperse said sanitizing mixture, said dispersion containing an emollient and having a pH of between about 4 and 7.
Claim 15
Dependent Claim
17 words
The method of claim 12 wherein said composition has a pH of between about 4 to 5.
