Patent number: 8623953Abstract: 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.Type: GrantFiled: April 16, 2009Date of Patent: January 7, 2014Assignee: Calumet Penreco, LLCInventor: Steluta Gina Butuc

Patent number: 6881776Abstract: Two-phase gel compositions are provided. The two-phase gel compositions are obtained by mixing a gelled ester composition comprising a mixture of an ester compound and a polymer compound selected from the group consisting of triblock copolymers, star polymers, radial polymers, multi-block copolymers, and a combination thereof and a hydrophobic, non polar solvent. The gelled ester composition has a viscosity ?1 and the solvent has a viscosity ?2. The two-phase gel composition is substantially free of phosphate compounds and has a viscosity ? which is greater than or equal to ?1 and which is greater than or equal to ?2. The two-phase gel compositions are also obtained by mixing a gelled ether composition, a gelled alcohol composition, a gelled naturally-occurring fat and oil composition or a combination thereof with a hydrophobic, non polar solvent. The two-phase gel compositions may be used to suspend various solids, liquids and/or gases.Type: GrantFiled: May 11, 2001Date of Patent: April 19, 2005Assignee: PenrecoInventor: S. Gina Butuc
