摘要:
The present invention provides new silica composite capsules that can be easily prepared, a composition containing the silica composite capsules, and a transparent gel-form composition excellent in appearance transparency and texture in use, and in particular, a transparent gel-form composition with improved cleansing properties when used as a cleanser. Micelle/silica composite capsules can easily be obtained, in an aqueous system, by mixing a material capable of forming micelles in water and a water-soluble silane derivative having a specific structure in aqueous solution. In addition, emulsion/silica composite capsules wherein the periphery of emulsion particles in the inner phase is coated with silica, can easily be obtained by mixing a surfactant, water, an oil, and a water-soluble silane derivative having a specific structure. Moreover, a transparent gel-form composition showing excellent appearance transparency, the texture in use and cleansing properties, can be obtained by blending a water-soluble silane derivative having a specific structure into the formulation that contains a surfactant, an oil and water, and capable of taking a surfactant association structure with aqueous continuous phase or both of aqueous continuous phase and oil continuous phase in the formulation.

摘要:
To provide a vesicle-containing composition wherein the stability is improved and the rate of releasing drug or perfume is sufficiently restricted during administration in vivo or application to the skin surface. Silica polymerization on the outer surfaces of vesicles is facilitated by adding a specifically structured water-soluble silane derivative to an aqueous composition containing the vesicles composed of a surfactant and mixing them together, and vesicle-silica composites having silica-coated outer surfaces can be obtained, resulting in the improved stability of the vesicle-containing composition as well as the improved effect of restricting the rate of releasing drug or perfume during administration in vivo or application to the skin surface.

A vesicle-containing composition comprising; (A) a perfume, (B) a silicone oil, (C) a silicone surfactant, (D) one or more selected from the group consisting of ethanol, propylene glycol, dipropylene glycol, and 1,3-butylene glycol, and (E) water; wherein the (C) silicone surfactant forms vesicles, and the (A) perfume and the (B) silicone oil are present in the vesicle bilayer membrane.
摘要:
The object of the present invention is to provide a production method of water-soluble silane derivatives, the separation and purification of which are easy, and the reaction for which can be conducted under an industrially practicable temperature condition (under the temperature condition of 90° C. or lower) and to provide compounds with which solid gelatinous external preparations, with excellent stability against a temperature change and against an effect of additives and with excellent usability, can be prepared. The water-soluble silane derivative could be formed by the substitution reaction of a metal alkoxide with a polyhydric alcohol under the presence of a solid catalyst. According to this production method, the separation of the catalyst from the product is very easy, and the reaction can be carried out under the temperature condition of 90° C. or lower. The obtained water-soluble metal alcoholate derivative can satisfactory solidify an aqueous formulation of an external preparation by its blending thereinto. The obtained solid gelatinous external preparation has excellent stability against a temperature change and against the effect of additives. In addition, the external preparation is easily disintegrated during use; thus the usability such as easiness to be scooped up with fingers and spreadability during application is excellent.

摘要:
An idling revolution speed control which maintains an engine speed at a predetermined target idling revolution speed during the idling drive includes an engine idling mode which performs the idling revolution speed control through an engine and a motor idling mode which performs the idling revolution speed control through a motor. The two modes are switched in accordance with a battery charged state. During the idling drive in an engine cold state, an ignition timing of the engine in the motor idling mode is retarded and the retardation quantities R3, R4 are expanded to be larger than the retardation quantities R1, R2 in the engine idling mode. Thus, a rise in an exhaust temperature of the engine is promoted.
