  • Patent number: 9359585
    Abstract: In one embodiment, a liquid or flowable cleansing or skin treatment composition is described which is substantially nonaqueous and which has a continuous and a discontinuous phase. Components of the discontinuous phase can chemically react with each other or with water when water is blended with the nonaqueous cleansing or skin treatment composition during consumer use. In a second embodiment, a solidified cleansing or skin treatment composition is described which contains components that can chemically react with each other or with water when water is blended with the solidified cleansing composition during consumer use. Methods for treating the skin with the inventive compositions are also described.

  • Patent number: 7897334
    Abstract: The present invention provides a method for determining the predisposition of an individual to a skin condition comprising identifying the profilaggrin alleles present in the genome of an ex vivo sample taken from the individual. Skin conditions include the ability of an individual to produce Natural Moisturising Factors (NMF), dry skin and/or predisposition to detergent-induced erythema. Typically profilaggrin alleles are identified by determining the number of encoded filaggrin repeats. Methods of the invention are particularly useful for grouping individuals for the purposes of participation in clinical trials or for matching an individual to a cosmetic preparation.

  • Patent number: 7776347
    Abstract: The present invention comprises a structured premix or “delivery vehicle” composition designed as a carrier to enhance the benefit (e.g., via enhanced deposition or other mechanism) of a separate hydrophobic benefit agent(s) (for example, perfumes, skin lightening agents, etc.), from personal product compositions (e.g., liquid and bar cleansers, creams, emulsions, hair composition, deodorant etc.). When the structured benefit agent composition is separately prepared and combined with the personal product composition (preferably while structured, premix composition is still in molten or liquid state), the personal product composition with structured benefit agent carrier provides enhanced deposition of the structured benefit agent and enhanced effect of the separate hydrophobic benefit agent(s) in or on the carrier or in the presence of structured benefit agent carrier.

  • Patent number: 7744857
    Abstract: Antiperspirant compositions containing suspended antiperspirant actives in a water-immiscible carrier leave visible deposits on skin or clothing unless the actives are masked. The carrier mixture in compositions herein comprise an alkylsiloxane which is substituted by a group R4 of formula —CH2—C(Ph) (RB)—R5-Ph in which RB represents H or methyl and R5 represents an alkylene group containing 0 to 3 carbons, and in which the proportion of aryl carbon atoms is at least 60% of all carbon atoms in the molecule. Preferably, the substituent comprises diphenylethyl. Optionally, the siloxane can be capped by the residue of a substituted vinyl group other than R4 or an alkyl, cycloalkyl or aralkyl alcohol.
