Abstract
The present invention relates generally to gels that flow through an orifice. Specifically the invention relates to gels that are dispensed through a trigger spray nozzle or aerosol spray valve. Still more specifically, the invention relates to nonaquious gels containing polymers whose instantaneous viscosity reversibly decreases when the gel experiences shear loads. The invention includes spray gel compositions, methods of making spray gels and methods of dispensing gels whose viscosity exhibits an instantaneous temporary decrease in viscosity when the gel is subjected to shear force as happens when it flows through an orifice, such as a spray nozzle or aerosol valve.
Claims33
A composition of matter comprising at least one hydrocarbon base fluid mixed with at least one dibock copolymer, said copolymer being present in sufficient concentration for the composition to exhibit shear stresses that are a non-linear function of the fluid strain rate.
A composition of matter comprising at least one hydrocarbon base mixed with at least one dibock copolymer, said copolymer being present in sufficient concentration for the composition to be pseudoplastic
A method for increasing the at rest viscosity of a petroleum distillate product having a hydrocarbon base comprising adding sufficient diblock copolymer to said hydrocarbon base to make the product pseudoplastic.
A method for increasing the viscosity of a mineral oil, said method comprising adding to said mineral oil an effective amount of a shear-thinning pseudoplastic thickener.
A non-aqueous gel product suitable for dispensing through a spray mechanism, said product comprising a hydrocarbon base and a shear-thinning pseudoplastic thickener.
