Composition and method for producing lubricating, germicide foam
First Claim
1. A combined foam bovine teat and udder dip, and after milking post teat dip and udder wash formed by admixing a surfactant, water and a bacteria control agent with pressurized air in a flow and line mixer and subsequently depressurizing the admixture from an initial pressurized value in the flow and line mixer down to atmospheric pressure and into an open orifice in a connected teat cup surrounding the teat and adjacent udder area, the consistency of the foam being sufficient to apply penetrating and adherent foam to the teat and adjacent udder area for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of deleterious material therefrom;
- and if desired, following cessation of milking the post teat dip and after milking and udder wash which is not wiped off enables the teat including the teat end, for a sufficient length of contact time, thereby causing fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.

Abstract
A method for producing a foam surfactant, and foam product suitable for a combined bovine teat dip and teat wash comprises air pressurization of a surfactant solution containing a germicide, disinfectant, biocide, etc., passing the air-surfactant mixture through a flow or line mixer to a foam holding cup adjacent the teat area and expanding the mixture to atmospheric in the holding cup to produce an adherent surfactant foam product with reduced run-off, which both protects and reduces infection of the teat, particularly at the teat canal and surrounding udder area.

11. A combined foam teat and udder dip, and after milking post teat dip and udder wash formed by admixing a surfactant, water and a bacteria control agent with pressurized air under turbulent flow conditions and subsequently depressurizing the admixture from an initial pressurized value down to atmospheric pressure into an open orifice in a connected teat cup surrounding the teat and adjacent udder area, the consistency of the foam being sufficient to apply penetrating and adherent foam to the teat and surrounding udder area for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of deleterious material therefrom;
- and if desired, following cessation of milking, the post teat dip and after milking and udder wash which is not wiped off enables the foam to adhere to the teat including the teat end, for a sufficient length of contact time, thereby causing fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.

22. A combined foam bovine teat dip and after milking post teat dip formed by admixing a surfactant, liquid and a bacteria control agent with pressurized gas in a flow and line mixer and subsequently depressurizing the admixture from an initial pressurized value in the flow and line mixer down to atmospheric pressure and into an open orifice in a connected teat cup surrounding the teat area, the consistency of the foam being sufficient to apply penetrating and adherent foam to the teat for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of deleterious material therefrom;
- and if desired, following cessation of milking the post teat dip and after milking wash which is not wiped off enables the foam to adhere to the teat including the teat end, for a sufficient length of contact time, thereby enabling fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.

32. A method of producing a combined foam teat and after milking post teat dip formed by admixing a surfactant, liquid and a bacteria control agent with gas under pressure in a flow and line mixer and subsequently depressurizing the admixture from an initial pressurized value in the flow and line mixer down to atmospheric pressure, and into an open orifice in a connected teat cup surrounding the teat, the consistency of the foam being sufficient to apply penetrating and adherent foam to the teat for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of deleterious material therefrom;
- and, if desired, following cessation of milking, the post teat dip and after milking wash which is not wiped off enables the foam to adhere to the teat, including the teat end, for a sufficient length of contact time, thereby causing fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.

33. A combined foam bovine teat dip and after milking post teat dip, characterized as being a stiff foam providing gas bubble inclusions without walls inside a matrix of surfactant and liquid, the consistency of the foam being sufficient to penetrate deleterious material on the teat for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of the deleterious material therefrom;
- and if desired, following cessation of milking, the post teat dip and after milking wash which is not wiped off enables the foam to adhere to the teat including the teat end, for a sufficient length of contact time, thereby enabling fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.
