  • Patent number: 7381667
    Abstract: A non-woven hydroentangled textile is described formed in cross-section with a central area of low mass fiber density surrounded on both sides by areas of higher mass density. Further, a personal cleansing article is described wherein the hydroentangled textile is associated with a personal cleansing composition that includes a lathering surfactant. The composition is deposited onto, impregnated into or at least is partially enclosed by the textile. Also described is a process for producing the textile involving feeding into a hydroentangling unit a loose random assembly of fibers both above and below a fibrous screen modifying textile substrate.

  • Patent number: 7357266
    Abstract: The present invention is directed to a venting closure that reduces the amount of headspace in a container. The venting closure has a patch that changes the location and reduces the size of the vent opening. Accordingly, the vent closure enables a container which has a vent opening to holds more product without having to expand the size of the container.

  • Patent number: 7351682
    Abstract: 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.

  • Patent number: 7351749
    Abstract: 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.

  • Patent number: 7347991
    Abstract: 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.

  • Patent number: 7347990
    Abstract: 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.

  • Patent number: 7347992
    Abstract: 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.

  • Patent number: 7334621
    Abstract: A process and equipment for manufacture of a swab article is provided wherein a stick is placed onto a conveyor, adhesive is applied to one or both ends of the stick, a portion of cotton coil is attached to the adhesive bearing end, and a shaper bar or similar means forces the cotton to assume a teardrop profile by applying force parallel to the stick, wherein the shaper bar or similar means moves in a direction perpendicular to the stick at a different rate of speed than that of the stick. Differences in the rate of speed reduce tailing of cotton normally associated with drag.
