  • Publication number: 20070071703
    Abstract: The composition, preparation and use of a thickening system or master gel for oil based compositions, especially cosmetic compositions is described. These highly efficient master gels include: i) greater than about 10% to about 40% of an organoclay, ii) from about 70% to less than about 90% of a carrier oil comprising a substantially dissolved mixture of at least one silicone fluid and at least one organic oil wherein the total silicone fluids comprise from about 10% to about 90% of the carrier based on the total weight of the carrier, and ii) from 0.5% to about 6% of a polar activator. In a preferred embodiment the master gel contains from about 15% to about 30% of an organoclay and is chosen so that the viscosity of the master gel composition is at least 2.5 million cP as measured with a Brookfield viscometer at 1 rpm.

  • Patent number: 6749860
    Abstract: The present invention relates to absorbent articles including non-aqueous compositions for protecting the barrier function of the skin. The compositions can be applied to the bodyfacing surfaces of absorbent articles so that the compositions come into contact with the skin. The compositions of the invention have improved stability on the bodyfacing surfaces after processing. The compositions of the invention provide several benefits including prevention and alleviation of skin irritations associated with the use of absorbent articles. The compositions can include emollients, viscosity enhancers and extracted botanical actives.

  • Publication number: 20030130635
    Abstract: The present invention relates to absorbent articles including compositions having improved rheological properties. The compositions of the invention exhibit improved spreading characteristics and would provide a more even distribution of skin care compounds on the skin of the wearer of the absorbent articles. The improved spreading characteristics are quantified by a Tangent Delta measurement. The present invention also relates to absorbent articles including compositions that contain silicone elastomers.

  • Patent number: 5770551
    Abstract: A bleach granule is provided with 60-100% being an intimate mixture of an amido or imido C.sub.2 -C.sub.30 peroxy acid and a surfactant, in a weight ratio of 20:1 to 1:20. The most preferred peroxyacids are N,N-phthaloylaminoperoxycaproic acid (PAP); monononylamide of either peroxysuccinic acid (NAPSA) or peroxyadipic acid (NAPAA) and N,N'-terephthaloyl-di(6-aminoperoxycaproic acid) (TPCAP). Localized dye damage from the peroxy acid bleach is prevented by the presence of the surfactant. Bleach compositions and a method for cleaning a stained substrate with the bleach granule are also described.
