Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A bovine teat dip free of inorganic salts and having a pH of between 5.0 and 5.8, a viscosity of from 4 to 10 centipoise at 37° C. and comprising an oil-in-water emulsion of the following ingredients expressed in parts by weight: ______________________________________
polyethoxycetyl ether 0.5%
75 mole polyoxyethylene ether
of whole lanolin 4.6%
lauryl (poly-1-oxapropene)
oxaethane carboxylic acid
1.0%
propylene glycol 8.0%
2-bromo-2-nitropropan-1,3 diol
0.2%
organic base as necessary to
adjust pH to 5.0 to 5.8
water as necessary to bring
total volume to 100%

______________________________________
Claim 3
Dependent Claim
12 words
A composition according to claim 1 which also includes a FD&C color.
Claim 4
Dependent Claim
12 words
A composition according to claim 1 wherein the organic base is triethanolamine.
Claim 5
Dependent Claim
83 words
A method of making the composition of claim 1 which comprises combining the ingredients other than the 2-bromo-2-nitropropan-1,3 diol and water; heating the so combined ingredients to 65° C. to form an oil phase; heating the requisite amount of water to 65° C. in a separate vessel; adding the oil phase slowly to the hot water with stirring; adding organic base slowly and without back titrating until pH is a 5.2 to 5.5; cooling to below 40° C.; and adding the 2-bromo-2-nitropropan-1,3 diol.
Claim 6
Dependent Claim
117 words
The method of controlling mastitis in dairy cattle which comprises immersing the cow's teats in a dip according to claim 1 coating the teat with the emulsion; forcing some emulsion into the teat orifice and into the lower portions of the streak canal by hydrostatic pressure, draining the excess emulsion from the teat without washing so as to form a protective lipid barrier, and permitting a small quantity of the emulsion to collect at and when dry to seal the teat orifice with a soft, tacky film or beadlet of water soluble lipid that maintains its tackiness for at least 12 to 24 hours but which can be removed by washing with water before the next milking.
