Description

[Detailed description of the invention]

<Industrial Application Field> The present invention relates to a cosmetic composition characterized in that it contains oil and fat obtained by extraction from Pinus seeds as a cosmetic raw material. <Prior Art> Conventionally, fats and oils containing a large amount of linoleic acid have poor oxidation stability, so they have rarely been used as raw materials for cosmetics, and oils with a high content of oleic acid, such as olive oil and camellia oil, have usually been used. In addition, pine seeds are only used as food after removing their shells, or as ingredients for confectionery or cooking, and the development of more advanced uses has been awaited. <Problems to be Solved by the Invention> The present inventors have conducted various studies in order to obtain cosmetics with excellent properties using oils and fats containing a large amount of linoleic acid as raw materials. 5,9,12- as acid and unique component
The present invention was completed after discovering that a cosmetic containing octadecatrienoic acid and having excellent properties can be obtained. <Means for Solving the Problems> The present invention is a cosmetic containing oil and fat obtained from pine seeds. The present invention will be explained below. Pine seeds have a high oil content, with an oil content of 40 to 70% and water content of 1 to 7%. For extraction of fats and oils, solvents such as ether, petroleum ether, hexane, benzene, toluene, xylene, chloroform, and dichloroethane can be used, but any solvent that can extract fats and oils may be used. The color of the extracted crude oil obtained is light, and a light-colored oil can be easily obtained by a normal decolorization method using activated clay or activated carbon. This oil is characterized by containing 5,9,12-octadecatrienoic acid, which is hardly found in other plants, and it is not greasy like other oils and is smooth on the hands and has good permeability. It is excellent. Cosmetics using this oil spread well on the skin and are absorbed very smoothly into the skin, giving it an excellent feeling of use, forming a homogeneous film on the skin, causing no skin irritation, and containing vitamin E. It also has excellent properties that help nourish the skin. Production Example Production of Pine Seed Oil 100 kg of pine seeds were crushed, extracted with n-hexane, and the solvent was removed to obtain 62.5 kg of yellow pine seed crude oil. Next, purified pine seed oil is purified by conventional methods of degumming, alkali deacidification, decolorization with clay activated carbon, and steam deodorization.
Obtained 56.5Kg. Table 1 shows the properties of pine seed crude oil and refined oil.

[Table] Example 1 (Cleansing Cream) (1) Formulation Raw materials Mixing ratio (% by weight) Paraffin 9.0 Beeswax 3.0 Refined pine seed oil 16.0 Liquid paraffin 41.0 Sorbitan sesquioleate 4.2 Polyoxyethylene sorbitan 0.8 Monooleate ester (20E. O) Fragrance, preservative, antioxidant Appropriate amount Purified water 26.0 (2) Preparation method Heat and mix the oily ingredients and keep at 65℃, then add it to purified water that has been preheated to 65℃ and stir.
After adding the fragrance, thoroughly emulsify with a homogenizer and cool to 35°C while stirring. Example 2 (emollient cream) (1) Compounding Raw materials Mixing ratio (wt%) Beeswax 6.0 Setanol 5.0 Refined pine seed oil 6.0 Squalane 37.5 Reduced lanolin 6.0 Glyceryl monostearate 2.0 Polyoxyethylene sorbitan 2.0 Monolauric acid ester (20E.O) Fragrance, preservative, antioxidant Appropriate amount Propylene glycol 5.0 Purified water 30.5 (2) Preparation method Add propylene glycol to purified water and keep at 70℃. Mix other ingredients and heat to dissolve at 70°C. This oil layer is added to the above-mentioned water layer for preliminary emulsification, homogeneously emulsified using a homomixer, and cooled to 30°C using a heat exchanger. Example 3 (emollient lotion) (1) Formulation Raw materials Mixing ratio (wt%) Refined pine seed oil 2.0 Microcrystalline wax 1.0 Beeswax 1.0 Lanolin 1.0 Liquid paraffin 30.0 Sorbitan sesquioleate 4.0 Stel Polyoxyethylene sorbitan 1.0 Monoolein Acid ester (20E.O) Aluminum stearate 0.4 Fragrance, preservative, antioxidant Appropriate amount Glycerin 8.0 Purified water 51.6 (2) Preparation method An emollient lotion was prepared in the same manner as in Example 2 by adding glycerin to purified water. . Example 4 (Lipstick) (1) Formulation Raw materials Mixing ratio (wt%) Castor oil 45.2 Hexadecyl alcohol 25.0 Lanolin 2.0 Refined pine seed oil 5.0 Beeswax 2.0 Ozokerite 4.0 Candelilla wax 7.0 Carnauba wax 2.0 Color Material 7.8 Fragrance, antioxidant, preservative Appropriate amount (2) Preparation method Heat and dissolve the base raw materials and mix uniformly. Coloring material is added to this, kneaded in a roll mill to uniformly disperse it, then remelted, flavoring added, defoamed, poured into molds, and rapidly cooled to solidify. Remove the solidified material from the mold and load it into a container. Next, the appearance of the stick is adjusted and passed through a flame to make the surface even. <Effects of the Invention> Examples 1 to 4 were all cosmetics with excellent feel and skin permeability. In this way, cosmetics using pine seed oil are products of excellent quality.
