Patent number: 6083897Abstract: Methods and compositions relating to solubilization of alkylbenzene sulfonate surfactants in detergent formulations. Addition of one or more polyethylene glycols to detergents including low 2-phenyl linear alkylbenzene sulfonate surfactants may be used to increase solubility of the low 2-phenyl linear alkylbenzene sulfonate surfactants. Increased solubility of the low 2-phenyl linear alkylbenzene sulfonate surfactants serves to lower the cloud point of the detergents, permitting formulation of liquid detergent compositions containing greater concentrations of low 2-phenyl linear alkylbenzene sulfonate surfactants.Type: GrantFiled: August 28, 1998Date of Patent: July 4, 2000Assignee: Huntsman Petrochemical CorporationInventors: Ronald G. Lewis, David C. Lewis

Patent number: 6080707Abstract: Disclosed is a stress stable lathering skin cleansing liquid composition comprising by weight parts of the liquid composition:(a) from about 0.5 parts to 10 parts of a crystalline, hydroxyl-containing stabilizer;(b) from about 1 part to about 80 parts of lipid skin moisturizing agent;(c) from about 1 part to about 30 parts of surfactant having a combined CMC equilibrium surface tension value of from 15 to 50;(d) water.Such stress stable lathering skin cleansing liquid compositions have a Lipid Deposition Value (LDV) of from about 5 to about 100. Such compositions are also stable for at least two weeks at 100.degree.
