Abstract

PROBLEM TO BE SOLVED: To provide a water-in-oil emulsified composition having no stickiness, good high-temperature storage stability and excellent barrier property, and a production method thereof.SOLUTION: A water-in-oil emulsified composition contains (A) a liquid oily substance, (B) a dextrin fatty acid ester, (C) a fatty acid ester where two or more hydroxyl groups of polyglycerol and a fatty acid are esterified, and (D) a higher alcohol and/or a higher fatty acid.

Description

  The present invention relates to a water-in-oil emulsion composition and a method for producing the same.

  Examples of emulsifier compositions used as cosmetics, pharmaceuticals, and quasi drugs include O / W type (oil-in-water type) emulsions and creams, and W / O type (water-in-oil type) emulsions and creams. Are known. O / W type emulsions and creams are excellent in system stability and usability, but are somewhat inferior in skin barrier properties and absorbability of medicinal components. On the other hand, W / O type emulsions and creams have the opposite properties to the above O / W type emulsions, and the skin surface is covered with an oil film to prevent contact with external factors such as bacteria, dust, and dust, and cause dryness. Suppresses moisture transpiration from the skin, and has excellent hydrophobicity and absorbability of medicinal ingredients. However, there is a drawback that the system is unstable and the water phase and the oil phase are easily separated. In order to prevent the separation of the water phase and the oil phase, it can be solved by using a large amount of a solid oily base. In this case, however, the feeling of use such as stickiness or reduced spread on the skin is reduced. There was a problem of getting worse.

  Polyoxyethylene surfactants are also widely used to improve stability, but these surfactants have good emulsifiability but poor high-temperature stability (40 ° C. or higher) and increase the amount used. In addition, it has been pointed out that there are safety problems such as poor feeling of use (stickiness) and rarely skin irritation.

Japanese Patent Laid-Open No. 2001-151662

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a water-in-oil emulsion composition having no stickiness, good high-temperature storage stability and excellent barrier properties, and a method for producing the same.

  The present inventors diligently studied to achieve the above object. In order to obtain a water-in-oil emulsion composition with little stickiness, it is necessary to reduce the amount of the oil component as much as possible. However, reducing the amount of the oil phase increases the chance of contact between the water phases, promotes coalescence, significantly reduces stability under high temperature conditions, and reduces the ability to suppress moisture transpiration from the skin. However, it is not desirable as a barrier ability to protect the skin from drying.

  Therefore, by using a dextrin fatty acid ester and a fatty acid ester in which two or more hydroxyl groups of polyglycerin and a fatty acid are esterified together, the liquid oily substance in the water-in-oil emulsion composition is 30% by mass or less. Even if it exists, the high temperature storage stability improved and the suppression effect of the moisture transpiration from skin was also favorable. In addition, it has been found that the production process in which the oil phase is added in two stages leads to further improvement in stability, and the present invention has been made.

Accordingly, the present invention provides the following water-in-oil emulsion composition and method for producing the same.

  According to the present invention, it is possible to provide a water-in-oil emulsion composition having no stickiness, good high-temperature storage stability and excellent barrier properties, and a method for producing the same.

Hereinafter, the present invention will be described in detail.
The present invention includes (A) a liquid oily substance, (B) a dextrin fatty acid ester, (C) a fatty acid ester obtained by esterifying two or more hydroxyl groups of polyglycerin with a fatty acid, and (D) a higher alcohol and / or a higher alcohol. It is a water-in-oil emulsion composition containing a fatty acid and containing 30% by mass of the component (A) in the composition.

(A) Liquid oily substance In the present invention, the liquid oily substance means a liquid at 25 ° C. Specific examples include squalane, crotamiton, dimethylpolysiloxane, diethyl sebacate, diphenhydramine, tocopherol acetate, ufenamate, diphenhydramine, diisopropyl adipate, linalool, borneol, eugenol, isoeugenol, and light liquid paraffin. From the viewpoint of suppressing stickiness, oil agents having an IOB (organic inorganic balance) of 0.4 to 1.0 are more preferable examples, and crotamiton (0.6), dimethylpolysiloxane (0.4), Diphenhydramine (0.4), diethyl sebacate (0.4), ufenamate (0.5), diisopropyl adipate (0.6), linalool (0.6), borneol (0.7), eugenol (0. 7), isoeugenol (0.7) and the like. More preferably, the oil agent whose IOB is 0.5-0.7 is mentioned. Moreover, from the point of suppressing stickiness, it is preferable that the ratio in the (A) component of squalane (0) having an IOB of less than 0.4, for example, is 75% by mass or less. A liquid oily substance having a high IOB has an advantage that stickiness is suppressed, but also has a point that the high-temperature stability of the water-in-oil emulsion composition is easily impaired. In the present invention, even when a liquid oily substance having a high IOB and easily impairing the high-temperature stability of the water-in-oil emulsion composition can be obtained, the high-temperature stability can be obtained. It can be compatible with sex.

  (A) The compounding quantity of a component is 30 mass% or less in a composition from the point of stickiness suppression, and 20 mass% or less is more preferable. The lower limit is preferably 5% by mass or more, more preferably 10% by mass, and further preferably 15% by mass from the viewpoint of high-temperature storage stability.

(B) Dextrin fatty acid ester Dextrin fatty acid ester is an oil gelling agent that gels an oil phase. In the present invention, (C) a fatty acid in which two or more hydroxyl groups of polyglycerin and a fatty acid are esterified. Stabilization can be improved by using ester together. Examples of dextrin fatty acid esters include caprylic acid dextrin, capric acid dextrin, lauric acid dextrin, myristic acid dextrin, palmitic acid dextrin, stearic acid dextrin, isostearic acid dextrin, arachidic acid dextrin, and behenic acid dextrin. Or 2 or more types can be used in appropriate combination. Of these, dextrin palmitate is preferred.

  (B) 0.1-10 mass% of the compounding quantity of a component is preferable in a composition, 1.0 mass% or more is preferable for a minimum, and 1.5 mass% or more is further more preferable. The upper limit is preferably 7% by mass or less, and more preferably 5% by mass or less. When the blending amount of the component (B) is too small, the effect of improving the high-temperature storage stability may be insufficient. On the other hand, when it is too large, the sticky feeling may be deteriorated.

(C) Fatty acid ester in which two or more hydroxyl groups of polyglycerin and fatty acid are esterified (C) Examples of the component include polyglyceryl polyoleate, polyglyceryl polystearate, polyglyceryl polyisostearate and the like. In the present invention, it is important to use a fatty acid ester obtained by esterifying two or more hydroxyl groups of polyglycerol and a fatty acid. If the esterification is performed only with one hydroxyl group of polyglycerin, the intended high-temperature storage stability cannot be obtained, and the barrier function becomes insufficient. Moreover, 4-10 are preferable and, as for the glycerol polymerization degree of polyglycerol, 10 is more preferable. In addition, the HLB value of (C) fatty acid ester is preferably 8 or less, and more preferably 5 or less. The HLB value refers to a value determined by the Griffin method (see Yoshida, Shindo, Ogaki, Yamanaka, edited by “New Edition Surfactant Handbook”, Engineering Books Co., Ltd., 1991, page 234). When using 2 types together, it calculates by the weighted average of the active agent to be used.

  (C) 0.3-10 mass% is preferable in a composition, as for the compounding quantity of a component, 0.5-5 mass% is more preferable, and 1-4 mass% is more preferable. By making it within such a range, higher temperature storage stability can be obtained, and when the amount is too large, the sticky feeling may be deteriorated.

(D) Higher alcohol and / or higher fatty acid Examples of the higher alcohol (C12-22) include lauryl alcohol, cetanol (cetyl alcohol), stearyl alcohol, behenyl alcohol, myristyl alcohol, oleyl alcohol, cetostearyl alcohol, and the like. Examples of higher fatty acids (8 to 22 carbon atoms) include caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidonic acid, behenic acid and the like. These may be used alone or in combination of two or more. Can be used in appropriate combination. The emulsion composition is stabilized by blending the component (D).

  Component (D) is preferably blended in an amount of 0.5 to 20 mass%, more preferably 1 to 15 mass%, further preferably 3 to 15 mass%, and particularly preferably 3 to 10 mass%. By setting it within such a range, higher temperature storage stability can be obtained, and if the blending amount is too small, the barrier property may be deteriorated.

  The composition of the present invention is a water-in-oil emulsion composition and has an action of suppressing moisture transpiration and has an excellent barrier function. However, an oil-in-water emulsion composition has an insufficient barrier function.

  In the present invention, polyhydric alcohols such as polyethylene glycol such as 1,3-butylene glycol and Macrogol 400 (Japanese Pharmacopoeia) can be blended singly or in appropriate combination of two or more. . However, from the standpoint of preventing stickiness, the blending amount is preferably 10% by mass or less in the composition, more preferably 5% by mass or less, and substantially not contained (depending on additives, etc. in other blending components). It is more preferable that the amount is 1% by mass or less in a small amount.

  In the water-in-oil emulsion composition of the present invention, optional components to be blended in the water-in-oil emulsion composition are used alone or in combination of two or more, as long as the effects of the present invention are not impaired. An appropriate amount can be blended.
