Patent number: 6995131Abstract: Clear, or translucent fabric softener compositions comprise fabric softener compound, principal solvent system, and high electrolyte levels. The high electrolyte level allows for a broader range of principal solvents to be used and/or reduces the incidence of increased viscosity when low levels of principal solvent are used. Phase stabilizers which are primarily ethoxylated hydrophobic materials can be used to reduce the amount of principal solvent that is needed and/or to stabilize the compositions in the presence of the highest levels of electrolyte. Specific phase stabilizers provide additional benefits including improved softening. Specific electrolytes provide improved results. Addition of primary solvents and/or phase stabilizers to the softener compounds can improve the viscosity/handling of the compounds and the ability to create the finished compositions.Type: GrantFiled: May 10, 1999Date of Patent: February 7, 2006Assignee: The Procter & Gamble CompanyInventors: Gayle Marie Frankenbach, Ellen Schmidt Baker, Rebecca Gayl Baker, Marc Johan Declercq, Hugo Jean Marie Demeyere, Ryan Matthew Heiden, Charles Albert Hensley, Brent Alan Kolb, Ruth Anne Murphy, Ronald Edward Pegoli, Toan Trinh, Errol Hoffman Wahl, Michael R.

Patent number: 5545350Abstract: Compositions are disclosed containing fabric softener compound having two hydrophobic groups attached to the remainder of the compound through ester linkages (DEQA), said compositions being concentrated and containing viscosity/dispersibility modifiers which are single long chain cationic surfactants, highly ethoxylated nonionic surfactants and/or mixtures thereof. Premixes of the DEQA and viscosity modifiers to lower the viscosity of the molten DEQA are disclosed. Processes for making aqueous liquid compositions from solid particulate compositions containing the DEQA are also disclosed.Type: GrantFiled: November 3, 1994Date of Patent: August 13, 1996Assignee: The Procter & Gamble CompanyInventors: Ellen S. Baker, Jean-Francois Bodet, Hugo J. M. Demeyere, Frederick A. Hartman, Bruno A. Hubesch, Robert Mermelstein, Lucille F. Taylor, Errol H. Wahl
