Abstract

PROBLEM TO BE SOLVED: To obtain a seed oil contg. no glycproteins by treating with an absorbent an org. solvent extract obtd. from Jatropha multifida linne as a Euphorbiaceae plant. SOLUTION: Seeds of Jatropha multifida linne as a Euphorbiaceae plant are pulverized, and then admixed with an org. Solventsuch as n-hexane to be subjected to extraction at about 40 to 50 deg.C for about 1 hour. The resultant extract is conc. under reduced pressure while distilling the solvent off to obtain a seed oil. At least one absorbent selected from among activated clay, activated carbon, Al(OH)3 , etc., is added to the seed oil, which is than stirred under an N2 gas stream at about 40 to 50 deg.C, then cooled, and filtered to obtain a seed oil contg. no substantial toxic glycoproteins. Predetermined amts. of the refined seed oil, a higher alcohol such as centanol or oleyl alcohol, and a surfactant such as a polyoxyethylene higher alcohol ether are then mixed together, and admixed with hot purified water under heat and with stirring to effect emulsification, followed by cooling to obtain a cosmetic perpetration having a good protective effect, such as a hair treatment.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a novel seed oil extracted from seeds of Euphorbiaceae plants, a method for producing the seeds, and a cosmetic containing the seed oil as an active ingredient. A novel non-toxic seed oil having a moisturizing effect substantially containing no glycoprotein component, and a method for producing this seed oil, and an effect of moisturizing the hair and skin with this seed oil as an active ingredient Regarding superior cosmetics.

[0002]

2. Description of the Related Art Conventionally, many natural vegetable oils and fats such as olive oil, castor oil and camellia oil, which are blended in cosmetics for the purpose of emollient (softening / moisturizing) effect on the stratum corneum of the skin, protection of hair and repair of damaged hair It has a drawback that it has a peculiar odor and that they tend to change over time. For the purpose of solving these problems, isopropyl myristate, which is a kind of synthetic oil having excellent stability over time, is widely used in cosmetics.

The seed oil crude plant used in the present invention is a plant natural in South America and naturalized in Indonesia. It is a shrub with a tree height of 2 to 4 meters, and it is now distributed almost all over Indonesia. The leaves are pale green with a diameter of about 15 cm and have deep incisions like palm leaves, the flowers are red-orange, the unripe fruits are green with a 2-3 cm conical shape and are divided into 3 chambers.
When it matures, it turns brown.

The mature seeds are covered with a blackish brown seed coat and have an oval spherical shape with a length of about 1 to 2 cm. Trees are used locally for ornamental use, and seed oil extracted by the conventional classical method is used for light. However, the seed coat contains ricin (r), which has cytotoxicity such as hemagglutination, which is common in Euphorbiaceae plants.
It is known to contain glycoprotein components such as lectin and lectin [T. Osbor
ne et al. , Am. J. physiol. , 1
4,259 (1905)], it is said that the oil cake is not suitable for feed. Therefore, there is no report so far that the seed oil of this plant obtained by using the classical method was used for food and cosmetics. Further, there is no report that this seed oil was separated and refined, and no report that its composition was analyzed and confirmed.

Regarding the separation and purification of this seed oil, the problem is how to remove the glycoprotein component which is considered to be toxic to the seeds of Salmon Bayatropa.

[0006]

DISCLOSURE OF THE INVENTION The object of the present invention is to establish a method for separating and refining seed oil of Salmon Bayatropa, which is expected to have various uses as described above, and to effectively remove glycoprotein components which are considered to be toxic. To provide a new non-toxic seed oil that does not contain a specific amount, and a cosmetic that utilizes the properties of this seed oil.

[0007]

Means for Solving the Problems As a result of repeated studies for solving the above problems, the present inventors have found that there is no novel toxicity by extracting from seeds of salmon Bayatropa from which seed coat has been removed in advance with an organic solvent. Seed oil can be provided, and a novel non-toxic seed is obtained by further treating the extracted oil extracted from the seed of Salmon Baya tropa with an organic solvent with an adsorbent to remove the glycoprotein component having the above-mentioned toxicity. The present invention has been completed by finding that oil can be produced and that this seed oil is useful as an active ingredient in cosmetics.

[0008] That is, the first invention of the present invention is a plant of the Euphorbiaceae family of the Euphorbiaceae ( Jatropha multifid).
a Linne) is a seed oil substantially free of glycoprotein components.

A second aspect of the present invention is characterized in that seeds of Salmonella tropopa, a plant of the Euphorbiaceae family, are subjected to an organic solvent extraction operation, and the organic solvent extract is further treated with an adsorbent. Is a method for producing seed oil.
