Abstract: A gel composition or a nail polish comprising at least one cationic surfactant having a propylene oxide chain and/or an ethylene oxide chain, an organic modified clay mineral and a solvent. Addition of the specific cationic surfactant maintains the good thixotropy due to the organic modified clay mineral and restricts the change in viscosity with time and with a slight change in the content of the organic modified clay mineral to a very narrow range.

Abstract: A nail cosmetic composition containing an organically modified montmorillonite, a silica and a nonaromatic solvent, and preferably an anionic surfactant, is safe for use on the human body and is free from sedimentation of a pearl agent contained therein, has an excellent stability over a long period, and has good physical properties such as coating and useability.

Abstract: A modified powder or particulate material having a silicone polymer film coated on substantially the entire surface thereof, this powder or particulate material being produced by bringing at least one silicone compound, in the form of a vapor, having the general formula (I):(R.sup.1 HSiO).sub.a (R.sup.2 R.sup.3 SiO).sub.b (R.sup.4 R.sup.5 R.sup.6 SiO.sub.1/2).sub.c (I)Wherein R.sup.1, R.sup.2, and R.sup.3 represent, independently, hydrogen or a hydrocarbon residue having 1 to 10 carbon atoms, which may be substituted with at least one halogen atom, provided that R.sup.1, R.sup.2, and R.sup.3 are not hydrogen at the same time, R.sup.4, R.sup.5, and R.sup.

Abstract: A modified powder or particulate material coated on substantially the entire surface thereof with a film of a silicone polymer carrying a pendant group thereon, this powder or particulate material being produced by a process comprising the steps of(a) coating the powder or particulate material with a film of a silicone polymer having at least one Si-H moiety, and(b) carrying out an addition reaction of a compound capable of reacting with an Si--H moiety to the Si--H moiety in the silicone polymer of step (a), whereby the pendant group derived from said compound is bonded to the silicone polymer.

Abstract: A modified powder or particulate material having a silicone polymer film coated on substantially the entire surface thereof, this powder or particulate material being produced by bringing at least one silicone compound, in the form of a vapor, having the general formula (I):(R.sup.1 HSiO).sub.a (R.sup.2 R.sup.3 SiO).sub.b (R.sup.4 R.sup.5 R.sup.6 SiO.sub.1/2).sub.c (I)wherein R.sup.1, R.sup.2, and R.sup.3 represent, independently, hydrogen or a hydrocarbon residue having 1 to 10 carbon atoms, which may be substituted with at least one halogen atom, provided that R.sup.1, R.sup.2, and R.sup.3 are not hydrogen at the same time, R.sup.4, R.sup.5, and R.sup.

Abstract: A packing material for liquid chromatography, comprising particles having a silicone polymer film coated on substantially the entire surface thereof, the packing material being produced by a process comprising the steps of:(a) bringing at least one silicone compound having the general formula (I):(R.sup.1 HSiO).sub.a (R.sup.2 R.sup.3 SiO).sub.b (R.sup.4 R.sup.5 R.sup.6 SiO.sub.1/2).sub.c (I)wherein R.sup.1, R.sup.2, and R.sup.3 represent, independently, a hydrocarbon residue having 1 to 10 carbon atoms, which may be substituted with at least one halogen atom, R.sup.4, R.sup.5, and R.sup.

Abstract: Gel composition suitable for use in the preparation of nail enamel is provided. The gel composition contains a chip composition which is prepared by mixing, under heating and compression, organically modified montmorillonite clay, nitrocellulose, and a substance which is capable of swelling the montmorillonite clay and is capable of plasticizing the nitrocellulose. The thixotropic nail enamel prepared from this gel composition has the advantages that a pretty glossy film can be obtained and the gelling state thereof is stable.

Abstract: Thixotropic nail enamel comprising, a gelling agent, a gel composition containing a chip composition which is prepared by mixing, under heating and compression, organically modified montmorillonite clay, nitrocellulose, and a substance which is capable of swelling the montmorillonite clay and is capable of plasticizing the nitrocellulose is provided. The thixotropic nail enamel has the advantages that the viscosity thereof does not increase with the lapse of time and the gelling state thereof is stable. This gel composition can also delete toluene and xylene, which must be contained in the conventional nail enamel, from the thixotropic nail enamel of the present invention.
