Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to gel cosmetics, and more particularly to cosmetics, cleansing agents, massage agents,
The present invention relates to a gel composition that spreads easily and has a transparent appearance, which can be used as a pack cosmetic or a pharmaceutical base.

0002

[Prior Art] Gel cosmetics have been used in the past, but since these generally use hydrophilic polyglycerin higher fatty acid esters, the compositions tend to be sticky due to their physical properties. It had the disadvantage of being difficult to spread. Gel cosmetics also have the disadvantage that the gel becomes hard at low temperatures. On the other hand, gel cosmetics are preferred because they have a transparent appearance and have a refreshing feel, but the problem is that such gel cosmetics can only be obtained by using a specific surfactant. It becomes. Recently, as a new type of gel cosmetic, a gel emulsion consisting of oil in a surfactant has been applied to a cleansing agent (Japanese Patent Application Laid-Open No.
-46123), wash-off type gel-like oily cosmetics based on liquid crystal structure (Japanese Patent Publication No. 1-53845
No.) has been proposed.

0003

[Problems to be Solved by the Invention] However, from the viewpoint of storage stability, etc., it is said that gel cosmetics themselves are preferable to such gel-like non-gel cosmetics (liquid crystal structures).
It has been desired to eliminate the above-mentioned drawbacks of gel cosmetics.

0004

[Means for Solving the Problems] As a result of extensive research in order to obtain a gel composition that has an excellent feeling of use and is transparent in appearance, the present inventors have found that a specific hydrophilic surfactant, The present invention was completed based on the discovery that a gel composition satisfying the above requirements, particularly a soft gel composition having appropriate fluidity, can be obtained by combining a lipophilic surfactant, an oil, and the like. That is, the present invention comprises the following components (A) to (E) (
A) It is liquid or pasty at room temperature, and its HLB
is 11 or more, a hydrophilic surfactant consisting of one or more compounds selected from polyoxyethylene sorbitol fatty acid ester or polyoxyethylene glycerin fatty acid ester, (B) branched or unsaturated fatty acid mono of diglycerin; or a lipophilic surfactant consisting of one or more compounds selected from diesters, (C) a polyhydric alcohol, (D) a liquid or paste oil component, and (E) water. This is what we provide.

[0006] This hydrophilic surfactant is present in the gel composition of the present invention in an amount of 5 to 40% by weight (hereinafter simply expressed as "%").
In particular, it is preferable to mix 10 to 25%. When the amount of hydrophilic surfactant is 5% or less, or conversely 40%
If it is more than that, the gel may not be formed or the gel may become opaque, which is not preferable.

[0007] Furthermore, a lipophilic surfactant (hereinafter referred to as "lipophilic surfactant") comprising one or more compounds selected from mono- or diesters of branched or unsaturated fatty acids of diglycerin used in the present invention. ) Examples include diglyceryl monooleate, diglyceryl dioleate, diglyceryl monoisostearate, diglyceryl diisostearate, and the like. This lipophilic surfactant is present in the gel composition of the present invention in an amount of 1 to 15%,
In particular, it is preferable to mix 5 to 10%. If the amount of lipophilic surfactant is less than 1%, or conversely more than 15%, it is not preferable because a transparent gel may not be obtained.

Examples of polyhydric alcohols in the ingredients of the present invention include propylene glycol, 1,3-butylene glycol, ethylene glycol, 1,3-propanediol, tritylolpropane, 1,4-butanediol, and 1,5-butylene glycol. -pentanediol, diethylene glycol,

[0009] The amount of polyhydric alcohol blended into the gel composition is preferably 1 to 50%, particularly 5 to 20%. If the amount of polyhydric alcohol is less than 1%, a transparent gel may not be obtained or two-layer separation may occur; conversely, if it is more than 50%, a transparent gel may not be obtained. This is not preferred because the activator layer may separate.

Furthermore, liquid or paste oil components (hereinafter referred to as "oil components") include squalane, olive oil, isopropyl myristate, batyl monoisostearate, vitamin E acetate, pyridoxine dioctanoate, and liquid petrolatum. , glycerol tris-2

[0011] The blending amount of this oil component is preferably 10 to 90%, particularly 30 to 80%, and the blending amount is preferably 10% to 90%.
Below, you may not be able to obtain a transparent product, and conversely, 9
If it is more than 0%, it is not preferable because a transparent product cannot be obtained or the gel becomes weak.

The content of water in the transparent gel composition of the present invention is preferably 1 to 50%, particularly 2 to 30%. If the amount of water added is less than 1%, it may become cloudy or water separation may be observed; on the other hand, if it is more than 50%, it may become cloudy.

[0013] The transparent gel composition of the present invention is prepared by mixing each component according to a conventional method, and a preferred manufacturing method includes a hydrophilic surfactant, a lipophilic surfactant,
An example of this method is to prepare a gel by uniformly mixing a polyhydric alcohol and water, and then add and disperse an oil component thereto to obtain a transparent gel-like material. In this method, if some components or additives are in the form of a paste or solid, they may be dissolved by heating as appropriate.

[0014] In addition to the above-mentioned essential components, various optional components can be added to the transparent gel composition of the present invention, if necessary. Examples of these optional ingredients include drugs, preservatives, coloring materials, etc. commonly used in cosmetics and pharmaceuticals.
