  • Patent number: 7235229
    Abstract: A clear, stable, dry-and-non-sticky feeling antiperspirant having an antiperspirant active, a solvent, and a polar silicone emollient. The antiperspirant active is solubilized in the solvent. The polar silicone emollient has an OH group or polyether or mixture thereof. The polyether has an average length of 6 or less of ethylene oxide, propylene oxide or butylenes oxide groups or mixtures thereof. The polar silicone emollient has a chain of dimethyl siloxane groups ranging in an average total length of 8 to 40 silicone atoms. The polar silicone emollient has a linker which is a hydrocarbon chain of 1 to 8 carbons in average length. The polar silicone emollient represents from about 1% to about 95%, more specifically from about 5% to about 70%, even more specifically from about 10% to about 40% by weight of the antiperspirant. The antiperspirant may be contained in a pressurized or non-pressurized container.

  • Publication number: 20040223936
    Abstract: Cosmetic, household and healthcare compositions containing a hydrocarbyl functional organopolysiloxane are disclosed. The hydrocarbyl functional organopolysiloxane contains at least one siloxy unit of the formula—R2OCH2CH2OH, where R2 is a divalent hydrocarbon group containing 2 to 6 carbon atoms. The inclusion of the hydrocarbyl functional organopolysiloxane results in personal, medical and household care compositions with improved performance and/or stability.

  • Publication number: 20040197285
    Abstract: Sunscreen compositions containing a hydrocarbyl functional organopolysiloxane are disclosed. The hydrocarbyl functional organopolysiloxane contains at least one siloxy unit of the formula —R2OCH2CH2OH, where R2 is a divalent hydrocarbon group containing 2 to 6 carbon atoms. The inclusion of the hydrocarbyl functional organopolysiloxane in the sunscreen composition improves the sun-protection factor (SPF) of the sunscreen component and various personal, medical and household care compositions containing the sunscreen composition.
