  • Patent number: 9895305
    Abstract: A skin cleansing composition is provided. The skin cleansing composition comprises from about 0.1% to about 15%, by weight, of a plurality of biodegradable abrasive particles. The biodegradable abrasive particles comprise a safe and effective amount of polyhydroxy alkanoate (PHA) biodegradable polymeric material and comprise a particle size range from 10 ?m to 1500 ?m. The composition also comprises a multimodal particle size distribution of the biodegradable abrasive particles. The composition further comprises a dermatologically acceptable carrier.
    Type: Grant

  • Patent number: 8469621
    Abstract: A personal care product having a personal care composition and a dispensing container with the personal care composition disposed therein. The personal care composition may have a pre-dispense G? of at least about 5,000 Pa. The personal care product provides a G? preservation percentage of no less than 10%. The dispensing container can be a container body having a storage void containing the personal care composition, a movable partition at least partially disposed within the storage void, a drive mechanism connected to and able to advance the movable partition, and a dispensing plate joined to the container body. The dispensing plate has an orifice through which the personal care composition is dispensed. The orifice may have an inscribed circle diameter of about 1 mm to about 12 mm.

  • Patent number: 7316592
    Abstract: The present invention is directed to an electrical contact that incorporates a movable metal connection component such as a contact pin. The metal connection component is mounted within an insulating body. An electrically conducting path, from a contact head of the metal connection component to an interior of a base chassis is created only when a handset has been positioned within a cradle cavity of the base.

  • Publication number: 20070128137
    Abstract: The present invention relates to water in oil emulsion compositions comprising: from about 0.1% to about 15% of a non-emulsifying crosslinked siloxane elastomer; from about 0.1% to about 15% of an emulsifying crosslinked siloxane elastomer; from about 1% to about 40% of a solvent for the non-emulsifying and emulsifying crosslinked siloxane elastomers; optionally, from 0% to about 5% of an additional emulsifier; and from about 50% to about 99% of aqueous phase; wherein when shear stress is applied to the composition during spreading on skin, aqueous phase is released from the emulsion.
