Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to cosmetics and external preparations containing triglycerides of branched fatty acids obtained from lanolin fatty acids as oil phase components.

[0002]

BACKGROUND ART Triacyl glycerides which are conventionally used as an oil phase component in cosmetics and which are solid at room temperature include naturally derived products such as cocoa butter, shea butter, tallow, glyceride tripalmitic acid, glyceride tristearate, and tribehen. There are synthetic products such as acid glyceride and tri-tallow fatty acid glyceride.

[0003] The purpose of its use is to increase the viscosity and melting point of the oily base, to improve the feeling of use, and the like.

[0004]

However, when a naturally derived product is blended, there is a problem in stability against oxidation and stability due to polymorphism of crystals, and when a synthetic product is blended, a feeling of use is felt. Was not satisfactory.

[0005] An object of the present invention is to provide cosmetics and external preparations that solve the above-mentioned problems of the prior art.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that triglyceride of a branched fatty acid obtained from lanolin fatty acid (hereinafter referred to as tribranched fatty acid glyceride) has been improved in stability. An unprecedented skin cosmetic with a unique feel that is excellent, suppresses oiliness when applied to the skin, is breathable with a light, dry feel, retains moisture with a moist feel, and has an emollient property. The present inventors have found that hair cosmetics and the like can be provided, and have completed the present invention.

That is, the object of the present invention can be achieved by a cosmetic and an external preparation characterized by containing tri-branched fatty acid glyceride as an oil phase component.

[0008] The branched fatty acid obtained from lanolin fatty acid in the present invention can be obtained as a non-hydroxy fatty acid from lanolin fatty acid contained in wool fat by the following method, for example.

That is, a method in which the hydroxy fatty acid component in the lanolin fatty acid is converted into a borate ester, followed by distillation under reduced pressure to separate the non-hydroxy fatty acid component and the hydroxy fatty acid component (JP-A-6-234994), or lanolin fatty acid methyl ester in a solvent After separation of the ω-hydroxy fatty acid methyl, non-hydroxy fatty acid and α-hydroxy fatty acid methyl can be separated by a method such as column chromatography using activated clay, alumina, silica gel or the like as an adsorbent. Branched fatty acids can be obtained as fatty acids.

[0010] The branched fatty acid obtained by the above method has the formula 1
Containing 30 to 45% by weight of an iso-type fatty acid represented by the formula, 30 to 50% by weight of an ante-iso-type fatty acid represented by the formula 2, and 10 to 30% by weight of a normal-type fatty acid represented by the formula 3, The total amount with the anteiso fatty acid is at least 60% by weight and the content of the hydroxy fatty acid is 1%;
Less than 0% by weight. The branched fatty acid in free form has a melting point (based on the second method based on Japanese cosmetic raw material standards) of 25 to 25.
The acid value is in the range of 140 to 210 and the saponification value is in the range of 160 to 210.

[Formula 1] Iso-type fatty acid CH3-CH (CH3)-(CH2) n-COOH n = 8-28

[Formula 2] Anteiso fatty acid C2H5-CH (CH3)-(CH2) n-COOH n = 8-28

[Formula 3] Normal type fatty acid CH3- (CH2) n-COOH n = 8-28

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto.

Production Example 1 A production example of tri-branched fatty acid glyceride using a branched fatty acid obtained by fractionating lanolin fatty acid by the method disclosed in JP-A-6-234994 is shown below.

In a 2 L four-necked flask equipped with a stirrer, a thermometer and a nitrogen gas injection tube, branched fatty acids (acid number 178.
6, saponification value 185.4, hydroxyl value 11.2, melting point 5
(0.1 ° C.) 942 g and glycerin (92.1 g) were added, and dissolved by heating under a nitrogen stream. After reacting at 220 ° C. for 16 hours, the mixture was allowed to cool to 80 ° C., and 10 g of activated clay and 2 g of a filter aid were added. After stirring for about 30 minutes, the mixture was filtered under pressure to obtain 892 g of branched fatty acid glyceride. The obtained branched fatty acid glyceride contained 77.8% of tri-branched fatty acid glyceride, 23.1% of di-branched fatty acid glyceride, and 0.1% of mono-branched fatty acid glyceride.

The analysis values of the obtained branched fatty acid glyceride were as follows: acid value = 0.13, saponification value = 168.8, and hydroxyl value = 24.9.

Example 1 In order to examine the compatibility of the branched fatty acid glyceride obtained in Production Example 1 with other oils, olive oil, octyl palmitate, methylpolysiloxane (10 cSt): triisooctanoic acid glyceride (1: 1 weight) Mixture). The ratio of the branched fatty acid glyceride to the other oil agent was 20:80 (weight). The temperature was evaluated at 80 ° C. and then at 25 ° C. The results are shown in Table 1.

Comparative Example 1 A compatibility test was carried out in the same manner as in Example 1 except that shea butter and tristearic acid glyceride were used instead of the branched fatty acid glyceride of Example 1. The results are shown in Table 1.

As can be seen from Table 1, the branched fatty acid glyceride is uniformly dissolved at 80 ° C. in any of the oils, and becomes a uniform gel without cooling down to 25 ° C. without deposits and phase separation. It showed compatibility.

In Table 1, "◎": transparent and homogeneously dissolved. "O": A uniform gel was formed. "X": A precipitate or phase separation occurred.

[0063]

[Table 1]

Test Example 1 The hydrophilicity of the gel with each oil agent obtained in Example 1 was measured. Hydration is performed by placing 10 g of the gel with each oil agent in a mortar, kneading well with a pestle while dropping water on the mortar, and weighing the weight of the water kneaded until water cannot be kneaded.
It was shown as a percentage with respect to 0 g. As shown in Table 2, the results showed higher water hydration than lanolin, which is known as an emollient. In addition, the feel of the obtained hydrated cream was also good.
