  • Patent number: 6982076
    Abstract: The present invention relates to a nail-care composition. It is an object of the present invention to provide a solvent-based nail-care composition which can be easily applied to nails, provides a film (coating film) on the nail with excellent strength and gloss, and generates a coating film that is difficult to peel off over time and free from loss of gloss. The means used to meet the objective is a nail-care composition comprising (a) nitrocellulose, (b) neopentyl glycol trimellitate adipate polyester resin, (c) one, two, or more members selected from the group consisting of alkyl methacrylate-alkyl acrylate copolymers, sucrose benzoate, and a polymer compound having a glass transition temperature of 50-80° C., and (d) a solvent. The present invention provides a solvent-based nail-care composition which is easy to apply, excellent in the strength of film(coating film) on the nail and gloss, difficult to peel off over a period of time, and free from the loss of gloss.

  • Patent number: 6814797
    Abstract: The present invention provides a gel composition capable of maintaining a high viscosity controlling ability over a wide polarity range from a low to a high polarity and also capable of exhibiting an excellent viscosity stability over a prolonged period as well as such nail enamel. The composition comprises cation-modified clay mineral, wherein cations of said cation-modified clay mineral comprise quaternary ammonium cation represented by Formula (I): wherein R1 is a C1-9 alkyl group, a phenyl group or a C7-9 aralkyl group and R2 is a C10-36 alkyl group, and Formula (II): wherein R3 and R4 are independent from each other and each represents a C10-36 alkyl group. Preferably, said cation-modified clay mineral comprises cation-modified clay minerals A and B whose cations are Cations (I) and (II) respectively in a weight ratio of A:B from 55:45 to 99.9:0.1.

  • Patent number: 5203991
    Abstract: A packing material for liquid chromatography bears a polyalkylene polyamine moiety linked through a spacer moiety as the pendant group to a porous silica gel coated with a silicone polymer, and optionally is crosslinked by a crosslinking agent on two or more amino group of the different polyalkylene polyamine moieties, and a process for production thereof. Such a packing material is especially useful in the analysis of sugars.
