Abstract

A teat dip composition useful for the treatment of mastitis in dairy cows. The composition in application form is in the form of an oil-in-water emulsion. The oil phase includes an unsaturated fatty acid, for example linseed oil fatty acid, having a carbon chan length in the range of C16 to C20.

Claims

1. A method of reducing the effects of mastitis in cows which comprises applying to the teats of the cow an amount of a composition consisting essentially of an oil-in-water emulsion of linseed oil fatty acid as the active ingredient and a stabilizing amount of an essentially non-ionic surfactant.

2. A method as defined in claim 1 wherein in said composition said linseed oil fatty acid is present in an amount of at least 20% by weight of the oil phase.

3. A method as defined in claim 1, wherein in said composition said active ingredient is hydrolyzed linseed oil.

4. A method as defined in claim 1, wherein said composition further includes glycerol.

5. A method as defined in claim 4, wherein said glycerol is present in an amount over 10% w/w of the fatty acid content.

6. A method as defined in claim 1, wherein in said composition said non-ionic surfactant is present in an amount of between 1 and 20% by weight of the oil phase.

7. A method as defined in claim 1, wherein in said composition there are at least two surfactants one with HLB less than 10 and one with HLB greater than 10.
