Abstract

PROBLEM TO BE SOLVED: To provide a viscous composition capable of showing smooth elongation and spread, while showing no drooping from skin or hair at the application time, and exhibiting an effect having excellent extending property.SOLUTION: This viscous composition contains fluorosilicic acid (sodium/magnesium), a (meth)acrylic acid-based thickening agent, preferably, at least one kind selected from a group of copolymers and crosspolymers containing a (meth)acrylic acid monomer and/or a (meth)acrylic acid alkyl monomer as a constituent, and water.

Description

  The present invention relates to a viscous composition.

  Conventionally, various thickeners and gelling agents are blended in cosmetics used for skin and hair from the viewpoint of imparting an excellent feeling of use by imparting a certain degree of viscosity to the composition. Among them, acrylic thickeners such as carboxyvinyl polymer and acrylic acid / alkyl methacrylate copolymer are the most widely used raw materials.

  However, since many acrylic acid thickeners have the property of being poor in salt resistance, the viscosity of the composition rapidly decreases due to the influence of salt contained in the skin, and when applied to the skin or on the hair. There is a problem that dripping occurs from the application site during application. In addition, there is a problem that smooth extension and spread are poor and an excellent feeling of use cannot be obtained.

  In order to solve such problems, attempts have been made to improve salt resistance. Specifically, for example, an aqueous gel cosmetic (for example, see Patent Document 1) containing a carboxyvinyl polymer, a basic substance, a hydrophobic silicic acid anhydride and a polyhydric alcohol, a carboxyvinyl polymer and / or an alkyl. An external composition containing a modified carboxyvinyl polymer and gellan gum (for example, see Patent Document 2) has been proposed.

  However, although these attempts can improve salt resistance to some extent, there is a problem that it is inferior in smooth spreading and it is difficult to obtain an excellent feeling of use.

  On the other hand, attempts have been made to impart viscosity with a prescription system using a clay mineral that is not affected by salt. Specifically, for example, a gel composition containing a clay mineral, fine-particle silica powder, and water (for example, see Patent Document 3), a gel composition containing a clay mineral, water, and an oil component that is liquid at room temperature. (For example, refer patent document 4), the gel-like composition (for example, refer patent document 5) containing an organic modified clay mineral and an oil agent etc. are proposed.

  However, although it is possible to give a certain degree of viscosity based on these attempts, if a sufficient amount of clay mineral is added to suppress dripping from the application site, a twist will be generated at the time of spreading, and thus smoothness will occur. However, there is a problem that it is difficult to obtain an excellent feeling of use.
