Patent number: 7351682Abstract: The invention discloses bar compositions which are milder than soap but have squeaky feel or rinse associated with soap. This is accomplished by ensuring at least a certain portion (at least 1%), or all, of the soluble surfactant system is ion-sensitive. Further, soluble soap comprises less than 1% by wt. of bar, which helps produce a less alkaline pH bar while allowing squeaky feel to be produced.Type: GrantFiled: March 8, 2005Date of Patent: April 1, 2008Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Teanoosh Moaddel, Yury Yarovoy, Michael Joseph Fair, Georgia Shafer, Christine Marie Nixon Lee, Frank Meyer

Patent number: 7351749Abstract: A process which may be continuous is provided for manufacture of personal care product compositions. The process involves feeding a first water phase which is a concentrate containing most if not all water soluble ingredients of the composition into a blending tube. A second phase which can be oily or aqueous and a third water phase, the latter being essentially pure water, are also fed into the blending tube. All of the phases are transported through the tube at a flow rate of about 5 to about 5,000 lbs./minute and at a pressure of about 10 to about 5,000 psi. Preferably the tube leads into a homogenizer such as a sonolator.Type: GrantFiled: December 16, 2002Date of Patent: April 1, 2008Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Peter Anthony Divone, Walter Anthony Biercevicz, Joseph James Regan, Christy Ann Bridges, Kimberly Ann Priest, Matthew Jungblut

Patent number: 7347991Abstract: Anhydrous cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and containing a suspended particulate antiperspirant or deodorant can suffer from either somewhat poor physical stability when formed, or preparative difficulties using conventional processes for making stick compositions or opaqueness. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—RX in which RX represents a branched C6 to C11 alkyl group in combination with a further amido structurant (ii), selected from (iia) N-acylaminoacid amides other than (i), (iib) cyclodipeptides and (iic) a 1,2-di amido-substituted cyclohexane.Type: GrantFiled: May 10, 2004Date of Patent: March 25, 2008Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Bruce Steven Emslie, Kevin Ronald Franklin, Neil Robert Fletcher

Patent number: 7347992Abstract: Anhydrous cosmetic antiperspirant stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant can exhibit undesirable sensory properties when 12-hydroxy-stearic acid is employed as primary gellant and the preparation of sick compositions suffers from sever processing difficulties when certain of such amido structurants are employed as primary gellant. Stick compositions having desirable sensory properties can be made by employing as primary gellant, a combination of amido structurants comprising (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—RX in which RX represents a branched C6 to C11 alkyl group and (ii) an N-acylaminoacid amide in which the N-acyl substituent contains a linear alkyl group and the cosmetic carrier oil comprising from 25 to 50% by weight of a water-immiscible monohydric alcohol that is liquid at 20° C. and a boiling point of higher than 100° C.Type: GrantFiled: May 10, 2004Date of Patent: March 25, 2008Assignee: Unilever Home & Personal Care USA division of Conpco, Inc.Inventors: Kevin Ronald Franklin, Jason Richard Williams

Patent number: 7347990Abstract: Many cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and an active cosmetic ingredient either exhibit poor physical stability when formed, or cannot be made readily using conventional processes for making stick compositions. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising in class (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—RX in which RX represents a branched C6 to C11 alkyl group in combination with a further amido structurant, (class (ii), including a polyamido-substituted cyclohexane, an amido derivative of di or tricarboxylic acids or an hydroxystearamide and particularly employing an N-acylaminoacid amide in which the N-acyl substituent contains a linear alkyl group, or a cyclodipeptide.Type: GrantFiled: May 10, 2004Date of Patent: March 25, 2008Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Bruce Steven Emslie, Kevin Ronald Franklin, Martin Peter Cropper
