Abstract

PROBLEM TO BE SOLVED: To simultaneously improve the stable formulation with a composition for external use such as a cosmetic and salt resistance while making the most of a unique tough of use of gellan gum. SOLUTION: This stable composition for external use is obtained by formulating a carboxyvinyl polymer and/or an alkyl-modified carboxyvinyl polymer and gellan gum in combination without formulating a surfactant for stabilizing the system.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to an external composition. More specifically, the present invention is an invention that provides a means for maintaining the viscosity of the composition for external use, and improving the stability and feeling of use of the composition.

[0002]

2. Description of the Related Art Stability and feeling of use are important factors in evaluating a composition for external use represented by cosmetics. As a typical means for improving the stability of a composition for external use, which has been conventionally performed, a considerable amount of a surfactant is incorporated. However, there is often a problem in the use feeling of an external composition containing a considerable amount of a surfactant. In recent years, in consideration of further safety and environmental considerations, it has been required to reduce the amount of the surfactant in the external use composition.

[0003] Therefore, in order to improve the feel and stability of use, attempts have been made to blend a water-soluble polymer such as a carboxyvinyl polymer or an alkyl-modified carboxyvinyl polymer, or a high-molecular polysaccharide such as gellan gum into an external composition. It has been done.

[0004]

However, both carboxyvinyl polymers and alkyl-modified carboxyvinyl polymers have a problem in that they are inferior in salt resistance and are unsuitable for blending into an external composition containing a salt.
In addition, gellan gum can impart a very unique usability to the composition for external use by blending it into the composition for external use. There was a problem that it was difficult to maintain the stability of the composition. Further, Japanese Unexamined Patent Application Publication No. 9-20649
As shown in the publication, gellan gum gels in the presence of cations, but the gel becomes agar-like, which is convenient when applied to foods, etc. Incorporation of gellan gum into the composition has been disadvantageous.

The problem to be solved by the present invention is to simultaneously improve the stable blending of cosmetics and other external compositions and the improvement of salt resistance while utilizing the unique feel of gellan gum.

[0006]

Means for Solving the Problems The present inventor has made intensive studies to solve this problem. As a result, in the composition for external use formulated by combining the carboxyvinyl polymer and / or the alkyl-modified carboxyvinyl polymer with gellan gum, surprisingly, the presence of the salt due to the interaction between these blended components. Even under, even in the absence, the viscosity of the entire composition increases, the use feeling is remarkably improved, and without incorporating a surfactant for stabilizing the composition. And found that a stable external composition could be obtained, and completed the present invention.

That is, the present invention is an invention which provides an external composition containing a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer and gellan gum (hereinafter, referred to as the external composition of the present invention). In the present invention, “external composition” means a composition that can be widely applied to the outer skin, and specific products include cosmetics, pharmaceuticals, and quasi-drugs under the Pharmaceutical Affairs Law. It does not ask for the distinction by such as.

[0008]

Embodiments of the present invention will be described below. Gellan gum to be incorporated in the composition for external use of the present invention includes: S. A. Pseudomonas Elodea (Pseudomonas Elodea ) in a medium containing glucose,
It consists of glucuronic acid and rhamnose (glucose: glucuronic acid: rhamnose = 2: 1: 1 ratio) and contains a heteropolysaccharide as a main component. Also, its molecular weight is
It is of the order of 670,000 to 920,000, and is a high-purity industrial product industrially produced under complete production control.
The structural formula is as follows, 1-3 linked glucose, 1-
4 bound glucuronic acid, 1-4 bound glucose, 1-
4 A linear high molecular weight polysaccharide composed of a repeating structure of rhamnose.

[0009]

[Formula 1]

[0010] The amount of gellan gum in the composition for external use of the present invention is 0.01 to 1.5% by weight based on the whole composition.
And particularly preferably 0.02 to 1.0% by weight. If the amount is less than 0.01% by weight based on the whole composition, it is practically difficult to sufficiently increase the viscosity of the whole composition in the first place.
If the amount exceeds the above range, a film unique to the polymer is formed in the system, and the feeling in use is rather deteriorated, which is not preferable. In addition, when it is added in excess of the same concentration, the whole composition becomes agar-like, and the tendency to become unsuitable as a composition for external use becomes remarkable.

The carboxyvinyl polymer blended with the gellan gum in the composition for external use of the present invention is an acidic polymer mainly composed of an acrylic acid polymer, and a commercially available product can be used. Specifically, for example, Hibiswako 103, 104, 105 (manufactured by Wako Pure Chemical Industries, Ltd.), Carbopol series (BF Goo
drich), Aqupec series (Sumitomo Seika), Junron PW series (Nippon Junyaku) and the like.

The alkyl-modified carboxyvinyl polymer blended with the gellan gum is a polymer mainly composed of an alkyl acrylate alkyl methacrylate copolymer, and a commercially available product can be used. Specifically, for example, CARBOPOL 1342, PEMULENTR-1, PEMULEN TR-2
(Manufactured by BF Goodrich).

In the composition for external use of the present invention, either one of the carboxyvinyl polymer and the alkyl-modified carboxyvinyl polymer can be selected and combined with gellan gum, and both can be combined with gellan gum and blended. It is also possible.

The compounding amount (including both the case where both the carboxyvinyl polymer and the alkyl-modified carboxyvinyl polymer are compounded and the case where either one is compounded)
Is 0.01 to 3.0% by weight, preferably 0.1 to 1.0% by weight, based on the whole composition.

[0015] The amount of this compound is 0.0
If the amount is less than 1% by weight, it sufficiently interacts with gellan gum to make it difficult to increase the viscosity of the composition, which is not preferable. An improvement in the effect corresponding to the compounding amount cannot be expected anymore, and it is difficult to sufficiently exhibit the intended effect of the present invention, which is not preferable.

The compounding ratio of duran gum to the carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer can be conveniently selected according to the dosage form of the composition for external use of the present invention. Gellan gum: carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer = 1: 100 to approximately weight ratio
It is preferable to mix them in a ratio of 150: 1, and it is particularly preferable to mix them in a ratio of 1:50 to 20: 1. If the ratio of the carboxyvinyl polymer or the alkyl-modified carboxyvinyl polymer is relatively large outside of this ratio, not only will excess carboxyvinyl polymer or the alkyl-modified carboxyvinyl polymer be wasted, but also the desired value of the present invention will not be sufficient. It is difficult to exhibit the effect, which is not preferable. Conversely, if the amount of gellan gum is relatively large,
A film peculiar to the polymer is formed on the composition, the feeling of use is reduced, and the whole composition becomes agar-like, which is inconvenient as an external composition.

In this way, by blending gellan gum and a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer into a cosmetic, a stable high viscosity can be obtained regardless of the presence or absence of a salt. In addition, it is possible to provide a composition for external use in which the feeling in use is significantly improved.
