Abstract
Abstract Bot eggs are readily removed from horse's hair by first applying to the eggs a thickened aqueous solution of an imidazoline or betaine surfactant in which the hydrophobe is a C 7 to C 12 hydrocarbyl group. This loosens the adhesion of the eggs so they can be scraped off easily, even by the use of a pad of metal wool.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A method for removing bot eggs from animal hair, which method comprises applying to the hair to soften the cement by which the eggs are adhered to the hair, a thickened aqueous solution containing at least about 2% of an amphoteric surfactant selected from the class consisting of imidazoline surfactants and betaine surfactants and having a hydrophobic C 7 to C 12 hydrocarbyl group, the solution having a viscosity of at least about 1000 centistokes at ambient temperature, and then scraping the hair having the softened adherents.
Claim 2
Independent Claim
87 words
A method for removing bot eggs from animal hair, which method comprises applying to the hair to soften the cement by which the eggs are adhered to the hair, a thickened aqueous solution containing at least about 2% of an amphoteric surfactant selected from the class consisting of imidazoline surfactants and betaine surfactants and having a hydrophobic C 7 to C 12 hydrocarbyl group, the solution having a viscosity of at least about 1000 centistokes at ambient temperature, and then scraping the hair having the softened adherents.
Claim 3
Dependent Claim
22 words
The combination of claim 1 in which the hydrophobe is a C 8 hydrocarbyl group and the surfactant concentration is about 2%.
Claim 4
Dependent Claim
15 words
The combination of claim 1 in which the applied composition is worked into the hair.
Claim 5
Dependent Claim
17 words
The combination of claim 1 in which the scraping is effected with a mass of metal wool.
Claim 6
Dependent Claim
16 words
