Description

  The present invention relates to a stable oil-based composition containing an ester of dimer acid or a copolymer (copolymer) of dimer acid ester, a salt of tocopheryl phosphate ester and glycerin.

The ester of dimer acid is a dimer of long-chain unsaturated fatty acid (dimer) and an ester of alcohol, and is a viscous liquid oil under normal environmental conditions. The copolymer of dimer acid ester is a viscous oil agent under normal environmental conditions as well as dimer acid ester. Dimer acid esters include dimer dilinoleic acid di (isostearyl / phytosteryl), dimer dilinoleic acid hydrogenated castor oil, dimer dilinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl) and other raw materials for cosmetics. Known as. Since these components have high water holding power and emollient effect, they are blended in lipsticks, hair care agents, oily cosmetics or emulsified cosmetics as substitutes for highly viscous oily components such as lanolin (for example, Patent Document 1). Patent Document 2).
In addition, salts of tocopherol phosphates (tocopheryl phosphates) are incorporated in various pharmaceuticals and cosmetics as easy-to-use tocopherol raw materials because they exhibit solubility in water (Patent Documents 3 and 4) ). Further, sodium salt of tocopheryl phosphate (sodium tocopheryl phosphate) is an anionic amphiphile and is known to have a surface active function (Non-patent Document 1). Attempts have been made to prepare an emulsified composition using the surface active ability of this sodium tocopheryl phosphate (Patent Document 5, Patent Document 6, Patent Document 7, Non-Patent Document 1).

As a technique for obtaining an O / W emulsion of fine oil droplets, an emulsification technique using a surface science technique (D-phase emulsification method: Non-Patent Document 2) is known. This emulsification technique is an emulsification method using a surfactant phase, also called a D phase. The oil in the dispersed phase is dispersed and held in the surfactant phase (in the D phase) to form an O / D type emulsion, which is diluted with water or an aqueous phase to obtain an oil-in-water O / W type emulsion. In addition, O / D type emulsions are widely used as techniques that can be used in cosmetics as lip creams and cleansing agents that can be washed with water as they are.
When the O / D emulsion has an oil composition ratio exceeding 70%, the system forms a transparent gel.

Since cosmetics are applied directly to the skin, efforts are being made to reduce the amount of additives other than cosmetic ingredients as much as possible or to add no additives in consideration of the burden on the skin.
Looking at the conventional technology from this viewpoint, the cosmetic of Patent Document 1 is a technology related to an oil gel in which a dimer acid ester is solidified with a dextrin fatty acid ester such as dextrin palmitate. This technology requires a low-viscosity triglyceride as essential. It cannot be prepared by blending only dimer acid ester or dimer acid copolymer as a component. Therefore, other additives are required.

  Moreover, since the cosmetics using the oil gel of patent document 1 and patent document 2 are not the gel (O / D gel) which can be used for D phase emulsification mentioned above, and there is no water dispersibility, the solution of water or an aqueous phase Even if diluted, it does not become an O / W type emulsified composition, and when allowed to stand, it quickly separates into an oil layer and an aqueous layer. Moreover, when used as a cosmetic, it cannot be washed off with water alone because it is oily.

  An object of the present invention is to obtain an oily composition having a high water dispersibility and containing an ester of dimer acid and a dimer acid ester copolymer (copolymer) as an oil agent without using an additive such as an emulsifier. To do. Another object of the present invention is to obtain an O / W type emulsified cosmetic using this oily composition.

  The present inventor has confirmed that when a dimer acid ester is added to a mixture of a salt of tocopheryl phosphate and glycerin (phase D), a stable oily composition (O / D gel) containing a high amount of dimer acid ester is obtained. This is the heading and the present invention.

The main configuration of the present invention is as follows.
(1) An oily composition containing the following (A) to (C).
(A) Dimer acid ester or dimer acid ester copolymer dimer dilinoleic acid (isostearyl / phytosteryl), diisopropyl dilinoleate, (polyglyceryl-2 isostearate / dimerlinoleic acid) copolymer, (polyglyceryl isononanoate) -2 / dimerlinoleic acid) copolymer, dimerlinoleic acid hydrogenated castor oil, dimerlinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl), (diethylene glycol / hydrogenated dimerlinoleic acid) copolymer 50-80% by mass of one or more

ADVANTAGE OF THE INVENTION According to this invention, the oil-based composition which contains highly the ester of a dimer acid or the copolymer of a dimer acid ester can be obtained only using the surface active ability of a tocopheryl phosphate ester salt. The oily composition of the present invention can be used as a cosmetic.
In addition, the oily composition of the present invention has an O / D gel characteristic despite the fact that no emulsifier is used. Therefore, the oily composition is instantly dispersed in water or an aqueous phase solution to form an O / W emulsion composition. This O / W emulsion composition is a cosmetic containing a high content of an ester of dimer acid or a copolymer of dimer acid ester. Further, the ester of dimer acid and the copolymer of dimer acid ester have a large molecular weight, and when an O / W type emulsion composition using normal phase emulsification is used, the particle size is large and a feeling of use with a sticky feeling is obtained. Since the O / D gel can be formed by adopting the constitution of the present invention, the particle size of the dimer acid ester or the dimer acid ester copolymer is reduced, and the cosmetic with excellent feeling of use with little stickiness. It becomes.

  The oil-based composition of the present invention is a composition having the same characteristics as the D-phase gel without using a surfactant or an emulsifier. In the present specification, in order to explain the present invention, the composition of the present invention may be referred to as a D-phase gel or an O / D gel. Further, a mixed solution of sodium tocopheryl phosphate and glycerin prepared in the process of obtaining the composition of the present invention may be referred to as D phase.

In addition, when it exceeds 80 mass%, the viscosity of an oil-based composition may become high and may interfere with stirring, and when it is 30% or less, separation of the oil-based composition may occur.

(B) Tocopheryl phosphate salt The salt of tocopheryl phosphate used in the present invention is preferably a metal salt such as sodium salt, disodium salt, potassium salt, dipotassium salt. Particularly preferred is tocopheryl phosphate sodium salt. The amount of the tocopheryl phosphate salt is preferably 0.1 to 5% by mass, more preferably 0.3 to 5% by mass when the total amount of the oily composition is 100% by mass.
In addition, the oil-based composition of this invention does not make water an essential component. The oily composition may be easily prepared by including about 2% by mass of water.

Sodium tocopheryl phosphate, which is a typical salt of tocopheryl phosphate used in the present invention, is in the form of a white to slightly yellow powder and readily dissolves in water at room temperature.
Sodium tocopheryl phosphate functions as vitamin E in the living body. Vitamin E is a useful vitamin as a fat-soluble vitamin, and has the function of protecting the skin from oxidative stress caused by ultraviolet rays in cooperation with water-soluble antioxidant compounds such as vitamin C. Sodium tocopheryl phosphate is derivatized because vitamin E itself is chemically unstable. Sodium tocopheryl phosphate is converted into vitamin E by dephosphorylating enzyme in the skin, and exhibits antioxidant and anti-inflammatory effects to improve rough skin. Expected for its beauty effect, it is blended into skin preparations such as cosmetics. Moreover, since it also has an antioxidant action, it is blended as an antioxidant.
Sodium tocopheryl phosphate is an amphiphilic vitamin E derivative having both hydrophilic and lipophilic properties and has high permeability to the skin. As what is marketed, "Vitamin E sodium phosphate" by Showa Denko KK can be illustrated, for example.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
1． Preparation of oily compositions of Examples 1 to 7 (1) Preparation procedure The content of dimerlinoleic acid (isostearyl / phytosteryl) LUSPLAN PI-DA (manufactured by Nippon Seika Co., Ltd.) having the composition of Table 1 is 30 to 30. An oily composition having 80% by mass was prepared.
The preparation procedure is as follows.
Mix sodium tocopheryl phosphate with glycerin and water and confirm that sodium tocopheryl phosphate is dissolved. Next, dimer linoleic acid (isostearyl / phytosteryl) is added in small portions with stirring. Stir each addition and add a smaller amount, making sure that the added amount is completely dispersed. Stir for a while after the addition of the entire amount. When dimer linoleic acid (isostearyl / phytosteryl) is difficult to disperse, it is prepared by stirring with gentle heating.
Example 7 is an example prepared without blending water when preparing glycerin and sodium tocopheryl phosphate.
The O / D gel of Examples 1-7 with which dimer linoleic acid was disperse | distributed to D phase by the above operation was obtained.
In addition, as shown in Example 7, it is clear that water is not essential for the formation of the O / D gel.

(2) Measurement of oil phase particle diameter in each obtained oily composition and confirmation of uniformity by half width (oil phase particle diameter)
The particle diameter of the emulsion composition obtained by diluting and dispersing 90% by mass of water to 10% by mass of each oily composition (O / D gel composition) was measured and this was determined as the oil phase particle diameter in the oily composition. I saw it. In the measurement, the particle diameter (volume average) of the dispersed oil phase was measured with a laser diffraction particle size distribution meter.

(Confirm uniformity)
Uniformity was evaluated by the half width value.
The half-value width is a distribution width of a particle size that is ½ of the volume peak of the obtained particle size distribution. It means that the particle | grains of an oil agent are homogenized, so that the value of a half value width is small. Further, the smaller the half width, the higher the stability. Similar to the oil phase particle size, the particle size distribution in the oily composition was measured using a laser diffraction particle size distribution meter. In the measurement, 90% by mass of water was added to 10% by mass of each oily composition (O / D gel composition), diluted and dispersed to measure the oil phase particle diameter, and the half width was obtained from the distribution histogram.
The particle diameter and half-value width are shown as the D phase state in the lower part of Table 1. The oil phase particle size was 1.6 to 2.5 μm, and the half width was 0.25 to 0.43. Both values indicated that the O / D gel was stable.
When each oily composition was stored at 25 ° C. and observed after 24 hours, no phenomenon such as separation was observed. However, the oily compositions of Examples 1 and 2 in which the blending amount of dimer linoleic acid (isostearyl / phytosteryl) was 50% by mass or less showed a tendency to be unstable over a long storage period. Therefore, it was predicted that the dimer linoleic acid (isostearyl / phytosteryl) should be 50% by mass or more in order to keep the oily composition stable for a long period of time.

  The composition of Example 6 in which 80% by mass of dimer linoleic acid (isostearyl / phytosteryl) was blended was very viscous and difficult to stir during preparation. Accordingly, the upper limit of the dimer acid ester is expected to be in the vicinity of 80% by mass. In the case of 70% or less, there was no problem. Moreover, all of Examples 1-6 disperse | distributed rapidly to water, and became a stable O / W type emulsion composition.

2. Preparation of oily compositions of Comparative Examples 1 to 7 (example in which no tocopheryl phosphate ester salt is blended)
(1) Preparation Procedure Based on Example 5, the content of dimer linoleic acid (isostearyl / phytosteryl) was changed to 70% by mass and changed to sodium tocopheryl phosphate, and used extensively in cosmetics to which D-phase emulsification technology was applied. An oily composition having the composition shown in Table 2 was prepared using two kinds of emulsifiers with proven results.
The preparation procedure is as follows.
A polyoxyethylene hydrogenated castor oil (20EO) and glycerin are mixed to confirm that the polyoxyethylene hydrogenated castor oil (20EO) is dissolved. Next, dimer linoleic acid (isostearyl / phytosteryl) is added in small portions with stirring. Stir each addition and add a smaller amount, making sure that the added amount is completely dispersed. Stir for a while after the addition of the entire amount.
Alternatively, polyoxyethylene octyldodecyl ether (25EO) is mixed with glycerin and water, and it is confirmed that polyoxyethylene octyldodecyl ether (25EO) is dissolved. Next, dimer linoleic acid (isostearyl / phytosteryl) is added in small portions with stirring. With each addition, a smaller amount is added while confirming that the amount added by stirring is completely dispersed. Stir for a while after the addition of the entire amount.
When dimer linoleic acid (isostearyl / phytosteryl) is difficult to disperse, it is prepared by stirring with gentle heating.

As shown in the lower part of Table 2, the compositions of Comparative Examples 1 to 7 in which the content of dimer linoleic acid (isostearyl / phytosteryl) was 70% by mass and the emulsifier was added instead of sodium tocopheryl phosphate were stable. Oily composition.
From Examples 1 to 6 and Comparative Examples 1 to 7, it was revealed that tocopheryl phosphate is suitable for O / D gel formation using dimer acid ester.

3. Preparation of oil-based compositions of Examples 8 to 13 (Examples in which the amount of tocopheryl phosphate was changed)
(1) Preparation Procedure Based on Example 5, the content of dimer linoleic acid (isostearyl / phytosteryl) was 70% by mass, the content of sodium tocopheryl phosphate and the content of glycerin were changed, and Table 3 An oily composition having the following composition was prepared. The preparation method is the same as that described above. Similarly, the oil phase particle diameter and half width were measured and shown in the lower part of Table 3.

As the blending amount of sodium tocopheryl phosphate increased, the particle size of the ester of (C) dimer acid tended to decrease (Examples 8 to 13). The compositions of Examples 8 to 13 all became stable oily compositions. Moreover, it disperse | distributed rapidly to water and became a stable O / W type | mold emulsion.
In Example 8 in which the blending amount of sodium tocopheryl phosphate was 0.1% by mass, the stability of the O / D gel tended to be somewhat lowered when stored for a long period of time. The lower limit of the formulation was expected to be in the vicinity of 0.1% by mass.

4). Preparation of oil-based compositions of Examples 14 to 20 (Examples in which various dimer acid esters or dimer acid ester copolymers were blended)
(1) Preparation procedure The oiliness of the composition of Table 4 which substituted dimer linoleic acid (isostearyl / phytosteryl) used in Example 7 by various commercially available dimer acid esters or dimer acid ester copolymers. A composition was prepared. The preparation method is the same as that described above. Also in Examples 14 to 20, the particle diameter of the oil phase was measured.

All of Examples 14 to 20 were stable oily compositions. Moreover, it disperse | distributed rapidly to water and became a stable O / W type | mold emulsion. Comparative Example 8 did not form an oily composition.

6). Example 21 (Preparation example of O / W type emulsified cosmetic)
15% by mass of the oily composition shown in Table 5 and 85% by mass of the diluent shown in Table 6 were mixed until uniform to prepare an O / W type emulsified cosmetic.

The obtained O / W type emulsified cosmetic had a viscosity of 2600 mPa · s, an emulsified particle diameter of 1.577 μm, and a half-value width of 0.296 on that day. This emulsified cosmetic was visually observed after being stored at 50 ° C. for 2 months, but no abnormalities such as oil floating or oil separation were observed, and it was confirmed that the cosmetic was stable.
When applied to the skin, it was not sticky and had an excellent feeling of familiarity.

6). Comparative Example 9 (Preparation Example of Cosmetics with Preparation Method Changed in Composition of Example 21)
A cosmetic having the same composition as the cosmetic of Example 21 was prepared by changing the preparation method.
That is, an emulsified cosmetic was prepared without forming an oily composition (O / D gel).
Sodium tocopheryl phosphate, glycerin and water (2% by weight) were mixed with the other aqueous phase components and heated to 80 ° C.
Subsequently, the oil phase component was mixed while heating to 80 ° C., and cooled to obtain an emulsified cosmetic.
This emulsified cosmetic had a viscosity of 2400 mPa · s, an emulsified particle size of 3.122 μm, and a half-value width of 0.322 on the day. Compared with the O / W type emulsified cosmetic of Example 21, the emulsified particle size was about twice as large.
When this emulsified cosmetic was applied to the skin, it was somewhat sticky and the familiarity was not preferable. Also, the storage stability was not good.

  As is clear from Example 21 and Comparative Example 9, it was revealed that the O / W type emulsified cosmetic according to the present invention is a stable O / W type emulsified cosmetic with reduced stickiness.
