Description

  The present invention relates to a cosmetic that is excellent in skin conformity and slipperiness at the time of application and a film feeling after application, and has good emulsification stability.

  Cosmetics such as milky lotion and moisturizing cream are indispensable for daily skin care in order to protect the skin and hair from moisture, transpiration and the external environment. These cosmetics are blended with an oil agent to give a smooth feel in addition to the purpose of moisturizing, moisture transpiration and protection from the external environment. Therefore, cosmetics generally take the form of emulsification such as oil-in-water emulsification in which an oil is dispersed in an aqueous phase and water-in-oil emulsification in which an aqueous phase is dispersed in an oil.

Since cosmetics are applied directly to the skin and hair, even if they are in a stable emulsified form, the product value is impaired if the feeling of use is inferior. Therefore, excellent skin conformity and slipperiness have been conventionally demanded. However, as a recent consumer demand, it is required that the film feeling after application is good.
Accordingly, there is a need for the development of a cosmetic material that has good skin fit and slipperiness when applied to the skin and hair and a good film feeling after application, and has high emulsification stability.

  In order to stabilize the emulsification, various proposals have been made so far. For example, an emulsion is an emulsified formulation that is more fluid than a cream and has poor stability against changes in viscosity, creaming, and sedimentation. In order to solve this problem, in an oil-in-water emulsion, an attempt has been made to impart stability by thickening an aqueous phase with a water-soluble polymer such as xanthan gum, guar gum, or carboxyvinyl polymer (for example, patents). Reference 1). However, when water-soluble polymers are used, the viscosity depends greatly on temperature and changes due to salts, resulting in lack of stability over time and stickiness when applied to the skin. It was not satisfactory.

  On the other hand, in creams, there is a proposal that blends waxes and waxes to improve the film feeling after application and prevent drying (for example, Patent Document 2). However, many waxes and waxes originally have a crystal structure, and there is a concern about precipitation over time, which causes a problem in stable blending. Furthermore, there is also a proposal using the α-gel structure of higher alcohol (for example, Patent Document 3). However, a sticky feeling derived from a higher alcohol was produced, and the feeling of use was not satisfactory when applied to the skin.

  Thus, the development of a cosmetic material that maintains emulsion stability, is excellent in slipping property at the time of application, and has an excellent film feeling after application has not been made so far.

(D) Water-soluble polyhydric alcohol (E) At least one oil selected from castor oil and castor oil fatty acid

(2) The cosmetic material according to (1), comprising 0.01% by mass or more of the component (E).

  The cosmetic of the present invention is excellent in stability over time, particularly heat stability. Furthermore, it is very useful because it has good skin conformability and slipperiness at the time of application and a good coating feeling after application.

[Component (A): 1,9,10-octanedecanetriol]
Component (A): 1,9,10-octanedecanetriol can be represented by the general formula (1). In the formula (1), the 9th and 10th carbon atoms are asymmetric carbons, but any optical isomer may be used.

  Component (A) can be obtained by a known production method. For example, by reacting 9-octadecen-1-ol with a hydrogen peroxide solution in the presence of a lower carboxylic acid such as formic acid or acetic acid, an oxirane ring is introduced into the unsaturated bond, and in the presence of an alkali or acid, an oxirane ring is introduced. Can be obtained by hydrolysis. As 9-octadecen-1-ol, cis-9-octadecen-1-ol, that is, oleyl alcohol is particularly preferred.

In the component (A), unreacted 9-octadecene-1-ol may remain within the range not impairing the effects of the present application, but the iodine value is preferably 10 or less. In addition, the iodine value is “a value obtained by converting the amount of halogen to be bonded to g of iodine when halogen is reacted with 100 g of a sample” and can be obtained according to JIS K-0070. The unit is represented by “I ₂ g / 100 g”.

  Component (A) can be used as an emulsification aid. Here, the emulsification aid is a base that improves the stability of emulsification by forming an association with a surfactant, and in the present application, it is described as a synonym for co-surfactant. doing.

  In particular, in order to achieve the object of the present application, it is effective to use a fatty acid ester type nonionic surfactant represented by component (B) and component (D) water-soluble polyhydric alcohol in combination. The component (A) has a freezing point of about 70 to 80 ° C., but if the freezing point is lower than the freezing point, aggregation is promoted, and emulsion stability and usability may be impaired. Components (B) and (D) contribute to alleviating aggregation and obtaining a stable emulsion. Furthermore, a component (A) makes the film | membrane feeling after application | coating favorable.

  The cosmetic of the present invention contains 0.01 to 10% by mass of the component (A). If it is less than 0.01% by mass, it is not effective as an emulsification aid, and the desired emulsification stability cannot be obtained. From such a viewpoint, 0.1% by mass or more is preferable, and 1% by mass or more is more preferable. Moreover, when it exceeds 10 mass%, even if it uses a component (B) and a component (D) together, aggregation cannot be relieve | moderated and the skin familiarity at the time of application | coating and slipperiness may be impaired. From such a viewpoint, 8 mass% or less is preferable, More preferably, it is 5 mass%.

[Component (B): Fatty acid ester type nonionic surfactant having HLB of 8]
The component (B) is a fatty acid ester type nonionic surfactant having an HLB of 8 or more, and the emulsion stability is improved by using it together with the component (A) and the component (D).

Note that the nonionic surfactant, polyoxyethylene, and polyoxypropylene may be simply expressed as nonion, POE, and POP, respectively. HLB is an abbreviation for Hydrophile-Lipophile Balance, and is a concept in which the balance of hydrophilic groups and lipophilic groups of a surfactant is quantified. Generally, 0 to 20 is indicated, and a higher numerical value indicates higher hydrophilicity.

The HLB of the application component (B) is calculated by the following formula. HLB = 20 (1-S / A) S: Saponification value of ester, A: Acid value of fatty acid Source: Tokiyuki Yoshida, Shinichi Shindo, Tadayoshi Ogaki, Kiyoshi Yamanaka "New edition surfactant handbook" Optical book stock Company October 1, 1987, p.234

The HLB of component (B) is 8 or more. In the case of a nonion having an HLB of less than 8, the lipophilicity becomes high and the fatty acid residue interacts with the component (A), which promotes aggregation of the component (A), which is not preferable. Furthermore, when applied to cosmetics, it may be inferior in the slipperiness at the time of application and the film feeling after application. From such a viewpoint, the HLB is preferably 10 or more.

The lipophilic group of the component (B) is particularly preferably an ester with a fatty acid having 10 to 24 carbon atoms from the viewpoint of reducing the aggregation of the component (A) and imparting emulsion stability. Even if the HLB is 8 or more, if the carbon number is smaller than 10, sufficient lipophilicity cannot be imparted and the desired emulsion stability cannot be obtained. From such a viewpoint, the number of carbon atoms is preferably 12 or more, and most preferably 14 or more. Similarly, even if the HLB is 8 or more, since the fatty acid residue interacts with the component (A) when the carbon number exceeds 24, even if the component (D) is used in combination, the component (A) Aggregation is promoted, which is not preferable. Moreover, when applied to cosmetics, the slipperiness at the time of application and the film feeling after application may be inferior. From such a viewpoint, the number of carbon atoms is preferably 22 or less.

  The fatty acid having 10 to 24 carbon atoms may be a saturated fatty acid, an unsaturated fatty acid or a branched fatty acid, and may further be a hydroxyl group-substituted fatty acid.
