  • Patent number: 6919074
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.

  • Patent number: 6899866
    Abstract: Sunscreen compositions including a dibenzoylmethane derivative, such as avobenzone, that are made more stable by the addition of (a) an ?-cyano-?,?-diphenylacrylate compound, e.g., octocrylene and (b) a diester or polyester of naphthalene dicarboxylic acid (diethylhexyl 2,6-naphthalate), having a weight ratio of (a)/(b) of at least 0.95, preferably at least about 1.0.

  • Patent number: 6878380
    Abstract: A wiping article is provided which includes an effervescent cleanser composition held within a pouch formed from a first and second substrate sheet. At least one of the substrate sheets must be water permeable. The effervescent composition is an intimate mixture of an acid material such as citric acid and an alkaline material such as sodium bicarbonate. Water contact causes the combination to effervesce. A dry surfactant such as sodium cocoyl isethionate in contact with the water and effervescing carbon dioxide results in a highly pleasant sudsing system. Skin benefit agents may be included within the composition. The effervescent action may improve deposition of the skin benefit agents onto the skin.

  • Patent number: 6824785
    Abstract: A composition which when topically applied to the skin of a mammal reduces trans-epidermal water-loss and provides an improved epidermal barrier contains an aqueous dispersion of at least two lipids, preferably at least three lipids, in a non-crystalline phase lamellar array, preferably bilayer membranes in the form of liposomes. These lipids adopt a crystalline lamellar phase upon application to mammalian skin which resist washing with mild detergents and water. The composition can be formulated as a pharmaceutical preparation, and can be used in a method of recovering or otherwise improving a mammalian skin permeability barrier by administering the composition to the skin or hair and allowing the composition to dry. The dried composition adopts a crystalline lamellar phase after said administering to the skin. The composition thus provides a permeability barrier in cases where the natural barrier has been depleted, damaged or requires improvement.
