Patent number: 7037887Abstract: 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: November 22, 2004Date of Patent: May 2, 2006Assignee: The Procter & Gamble CompanyInventors: Gayle Marie Frankenbach, Ellen Schmidt Baker, Rebecca Gayle 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 Rene Weaver, Dean Larry DuVal, John Henry Shaw, Jr., Masae Nogami, Ronghui Wu
