More specifically, the present invention relates to a gel-like composition that does not cause water separation or metal elution from a water-swellable clay mineral over time and has excellent usability (such as no stickiness immediately before drying).

  The following 4 documents are mentioned as a document which described the prior art close | similar to the gel-like composition of this invention.

  That is, in JP-A-4-334316 (Patent Document 1), by blending 5% by mass or more of water-swellable clay mineral and 0.3 to 0.7% by mass of polyethylene glycol, An invention relating to an external preparation for skin with reduced viscosity is described. However, the external preparation for skin of Patent Document 1 is to prepare a cream base by increasing the base hardness by blending a water-swellable clay mineral, and is intended to form a fluid gel as in the present invention. Not a thing. It is also difficult to ensure sufficient water separation stability.

  Japanese Patent Application Laid-Open No. 2009-96779 (Patent Document 2) describes a sprayable aqueous gel composition containing a water-soluble metal salt, fine particles of a layered silicate mineral, a water-soluble polymer (sodium carboxymethylcellulose), and water.

JP-A-4-334316 JP 2009-96779 A JP-A 61-194014 JP 2002-29928 A

  The present invention has been made in view of the above-mentioned conventional circumstances, and does not cause metal elution from water separation or water-swellable clay minerals over time, and is excellent in usability (no stickiness immediately before drying, etc.) The purpose is to provide.

  In order to solve the above problems, the present invention provides (a) a water-swellable clay mineral, (b) an organic acid having a pH of 3% by weight or more in an aqueous phase, and (c) a mass average molecular weight of 4 in the aqueous phase. 5,000 to 5,000,000 polyethylene glycol, component (b) / component (a) is 0.01 to 1.5 (mass ratio), component (c) / component (a) is 0 The gel composition is provided, wherein the gel composition is 2 to 10 (mass ratio) and the pH of the composition is 6.5 to 8.1.

  The present invention also provides the gel composition, wherein the organic acid as component (b) is an amino acid (the hydrogen atom of the amino group may be substituted with an organic group).

  Moreover, this invention provides the said gel-like composition whose (b) component is 1 type (s) or 2 or more types chosen from L-serine, glycine, and glycylglycine.

  Moreover, this invention provides the said gel-like composition whose compounding quantity of (a) component is 0.1-10 mass% in an aqueous phase.

  According to the present invention, a gel-like composition excellent in usability (such as no stickiness immediately before drying) is provided without water separation or metal elution from a water-swellable clay mineral over time.

  Hereinafter, the present invention will be described in detail.

  The water-swellable clay mineral as component (a) is a layered crystalline silicate mineral in which a layer containing crystalline silicate and a layer centered on metals such as Al and Mg are stacked, and is a smectite. Examples include genus clay minerals and swellable mica. Examples of the smectite clay mineral include bentonite, montmorillonite, beidellite, nontrolite, saponite, hectorite, stevensite, and teniolite. Examples of the swellable mica include fluorine tetrasilicon mica. These may be either natural or synthetic products. Commercially available products include Kunipia, Smecton (all manufactured by Kunimine Kogyo Co., Ltd.), Bee Gum (manufactured by Vanderbilt), Dimonite, Fluorotetrasilicon Mica (both manufactured by Topy Kogyo Co., Ltd.), Laponite (manufactured by Rockwood Additive). In addition, exfoliation type layered double hydroxide (= exfoliation type hydrotalcite) having the property of delamination in water is also exemplified, and acrylic acid type hydrotalcite, lactic acid type hydrotalcite, acetic acid type hydrotalcite, etc. are exemplified. Is done. Among these, smectite clay minerals are preferred because they are widely used as cosmetic ingredients. (A) A component can use 1 type (s) or 2 or more types.

  The component (b) is an organic acid having a 1% by mass aqueous solution having a pH of 3 or more. In the present invention, an amino acid is preferably used as the organic acid. The amino acid may be one in which the hydrogen atom of the amino group is substituted with an organic group (for example, glycyl group or the like). Examples of such amino acids include L-serine (pH of about 1% by mass aqueous solution of about 6.5), glycine (about 6.2), and glycylglycine (about 5.9). When the pH of a 1% by mass aqueous solution is less than 3, the amount of magnesium eluted from the clay over time is large, and the preparation aggregates over time to cause water separation. Further, among organic acids, the use of organic acids such as amino acids causes less burden on the skin than when inorganic acids or the like are used. (B) A component can use 1 type (s) or 2 or more types.

  The component (c) is polyethylene glycol (PEG) having a mass average molecular weight (Mw; hereinafter, also simply referred to as “molecular weight”) of 4,000 to 5,000,000. The molecular weight is preferably 4,000 to 4,000,000, particularly preferably 4,000 to 100,000. When the molecular weight is less than 4,000, the effect of suppressing water separation is insufficient, while when the molecular weight exceeds 5,000,000, the stickiness is strong, which is not preferable as a cosmetic. Specific examples of the component (c) include PEG 4,000, PEG 11,000, PEG 20,000, PEG 4,000,000 and the like. However, it is not limited to these examples. (C) A component can use 1 type (s) or 2 or more types.

  In the present invention, the above components (a) to (c) are essential components. Although the pH of the dispersion containing the component (a) is high, if an attempt is made to neutralize it with an acid having a low pKa (acid dissociation constant), the metal is eluted from the component (a) over time, causing aggregation and separation of water. Therefore, by combining the component (b), the pH of the system of the composition could be adjusted to near neutral with little metal elution from the component (a) over time. However, in the combination of only the component (a) and the component (b), water separation accompanying initial structural change was observed from the component (a) after preparation of the preparation. Therefore, in the present invention, by blending the component (c), water separation can be suppressed while maintaining the above effects.

  In the gel composition of the present invention, the components (a) to (c) are contained in the aqueous phase. The composition of the present invention may be a gel composition composed of an aqueous phase, or may be an emulsion system gel composition of an aqueous phase and an oil phase. The emulsification system may be either an oil-in-water type or a water-in-oil type. When an oil phase is included, it is preferable that the aqueous phase is 99.8 to 60% by mass and the oil phase is 0.2 to 40% by mass in the composition.

  (A) As for the compounding quantity of a component, 0.1-10 mass% is preferable in an aqueous phase, More preferably, it is 0.5-5 mass%, Most preferably, it is 1-2 mass%. If the blending amount of the component (a) is 0.1% by mass in the aqueous phase, the gelling function may not be exhibited. On the other hand, if it exceeds 10% by mass, the gel becomes too hard, which is not preferable as a cosmetic.

Component (b) is blended in an amount of 0.01 to 1.5 times (mass ratio), preferably 0.05 to 0.8 times (mass ratio), and particularly preferably 0.1 to 1.5 parts (a). It is 2 to 0.4 times (mass ratio). When the blending ratio (mass ratio) of the component (b) to the component (a) is less than 0.01, it is difficult to sufficiently exert the pH buffering effect. On the other hand, when it exceeds 1.5, the amount of Mg eluted from the clay increases. This is not preferable because the preparation tends to aggregate. In addition, it is preferable that the compounding quantity of (b) component in a gel-like composition shall be about 0.3 mass% or more.
(C) The compounding quantity of a component is 0.2-10 times (mass ratio) with respect to (a) component, Preferably it is 1-5 times (mass ratio). When the blending ratio (mass ratio) of the component (c) with respect to the component (a) is less than 0.2, it is difficult to sufficiently exert the water separation inhibiting effect. On the other hand, when it exceeds 10, the stickiness is strong and it is not preferable as a cosmetic. The amount of component (c) in the gel composition is preferably about 0.3% by mass or more.

1. Adjustment of pH of system by component (a) and component (b):
Each amino acid (neutralizing agent) shown in Table 1 below is added to a water-swellable clay mineral dispersion aqueous solution in which 2 g of water-swellable clay mineral (“Smecton SA”; manufactured by Kunimine Kogyo Co., Ltd.) is dispersed in 100 g of water. Immediately after the addition, 7 days later, 3 months later, the Mg elution amount (mg / g) was measured, and the appearance (transparency, water separation) was visually observed. The results are shown in Table 1. The Mg elution amount was measured by chelate titration method using Eriochrome Black T. During evaluation of “Appearance after 7 days” in Table 1, ○: No water separation, ×: Water separation was observed. In Tables 1 to 5, the samples described as “× (aggregation)” were in a muddy state in which the gel collapsed due to the aggregation of clay mineral particles due to a large amount of Mg elution.

  As is clear from the results in Table 1, when no neutralizing agent was added to the system containing the water-swellable clay mineral, the elution amount of Mg after 7 days was low, the appearance was transparent, and no water separation occurred. However, the pH of the system remained at a high pH value of approximately 9.6. When L-serine, glycine, or glycylglycine having a pH of 3% or more as a neutralizing agent is blended, the pH after 7 days has elapsed, the pH after 3 days has passed, and the pH after 3 months is almost the same. It became neutral to weakly alkaline, the pH value approached the neutral side, and an almost constant pH value was maintained. However, the water was removed after 7 days. On the other hand, when succinic acid having a pH of less than 3 in a 1% by mass aqueous solution is blended, the pH after 7 days has passed, the pH after 3 days has changed, and after 7 days, the clay mineral Mg has changed. Aggregates and becomes cloudy due to elution.
