  • Publication number: 20110089196
    Abstract: The present invention relates to a personal-care article comprising a package and a personal-care product. The package comprises at least one chamber, a dispensing orifice, a first zone proximate to the dispensing orifice, and a second zone distal to the dispensing orifice. The first zone and second zone are both located in at least one chamber. The personal-care product comprises a first personal-care composition substantially disposed within the first zone and the second personal-care composition substantially disposed within the second zone. The first personal-care composition comprises a first concentration of hydrophobic benefit material. The second personal-care composition comprises a second concentration of hydrophobic benefit material. The first concentration of hydrophobic benefit material is different from the second concentration of hydrophobic benefit material.

  • Publication number: 20070286832
    Abstract: The present invention relates to a multi-phase personal-cleansing composition comprising a first aqueous phase and a second aqueous phase packaged in physical contact with one another. The first aqueous phase comprises a surfactant, a salt and water. The second aqueous phase comprises a polymer, a salt and water. The molality of the salt of the first aqueous phase differs from that of the salt of the second aqueous phase by less than 6%. The weight percent of water in the first aqueous phase differs by at least 5% from that of the second aqueous phase. The viscosity of the first aqueous phase differs from that of the second aqueous phase by less than about 25%. Preferably, the polymer in the second aqueous phase is a high solution viscosity polymer having a 1% viscosity at pH 7 of greater than 750 centipose.
