Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cosmetic composition containing a specific oil and fat, and is characterized by having a feeling of use, stability, and an effect of preventing skin aging.

(B) Conventional Technology Vegetable oils commonly used in cosmetics include olive oil, castor oil, soybean oil, avocado oil, almond oil, camellia oil, coconut oil, etc., all of which have a triglyceride structure. However, the feel, physical properties, etc. differed greatly depending on the type, and were not always satisfactory.

That is, since ordinary vegetable oils contain a large amount of unsaturated acids such as oleic acid, linoleic acid and linolenic acid, there is a problem in terms of oxidative stability.

Further, although saturated fatty acid-based vegetable oils such as coconut oil are good in terms of oxidative stability, since they contain medium-chain fatty acids mainly of lauric acid, they have a problem of odor during decomposition and are also tactile. It tends to be rather heavy.

Therefore, the cosmetics using these oils and fats have been inadequate in terms of usability and stability.

(C) Problems to be Solved by the Invention An object of the present invention is therefore to provide an improved cosmetic product which does not have the above-mentioned drawbacks.

(D) Means for Solving the Problems As a result of research, the inventors of the present invention found that oils and fats obtained from Sasa have extremely excellent properties as cosmetic oils and fats, and based on this, completed the present invention. did.

That is, the present invention is a cosmetic characterized in that it contains an oil and fat obtained from spiny spines.

Sasa is a plant with the scientific name Hippophae Rhamnoides L., and is distributed in Zhangjiaji, China and other regions. Fruit oil and seed oil are obtained from this plant. The oil and fat in the present invention is a mixed oil of fruit juice oil and seed oil.
The mixing ratio of the fruit juice oil and the seed oil may be arbitrary, and the mixed oil is blended in an amount of about 3 to 25% by weight based on the whole cosmetic.

An example of the fatty acid composition of these oils and fats is shown in Table 1. The fatty acids constituting the fruit juice oil are 60% or more saturated and unsaturated fatty acids having 16 carbon atoms. Among them, 30 palmitooleic acid
It has a characteristic not found in ordinary vegetable oils in that it contains more than 100%. Palmitooleic acid has a good affinity with the skin and, when applied to the skin, has the property of immediately becoming sebum.

Also, fruit juice oil contains 1500 to 2000 ppm of tocopherol, of which 90% or more is α-tocopherol. Tocopherol plays a role of preventing skin aging by inhibiting the production of lipid peroxide and lipofuscin by its antioxidant effect. In addition, tocopherol is also lipophilic and has excellent affinity with the skin.

As described above, when the juice oil / seed oil mixture is used as a raw material for cosmetics such as various creams, emulsions, hair cosmetics, lipsticks, etc., conventional oils and fats provide the feeling of use, stability, and skin aging prevention Can prepare excellent cosmetics.

(E) Example Example 1 Emulsion blending raw material blending ratio (wt%) Saseki juice oil 4.0 Sasah seed oil 2.0 Beeswax 3.0 Scrawan 10.0 Glycerin monooleate 2.0 Liquid paraffin 3.0 Reduced lanolin 4.0 Polyoxyethylene sorbitan monolaurate (20E. O) 2.0 Fragrance, antiseptic Proper amount Propylene glycol 3.0 Purified water Residual preparation method Add propylene glycol to purified water to make water phase part,
Keep at 70 ° C. Separately, other ingredients are mixed to form an oil phase portion, which is heated and melted to 70 ° C. This oil phase part was added to the above-mentioned water phase part, emulsified with an emulsifying machine, and then cooled to obtain an emulsion.

Example 2 Emollient cream compounding raw material compounding ratio (% by weight) Sasa fruit juice oil 3.0 Sasa seed oil 3.0 Beeswax 4.5 Cetanol 4.0 Scrawan 31.0 Glycerin monostearate 3.5 Microcrystalline wax 6.0 Reduced lanolin 6.0 Polyoxyethylenesorbitan monolaurate (20E.0) ) 2.0 Fragrances, preservatives Proper amount Propylene glycol 4.0 Purified water Residual preparation method Similar to Example 1 Example 3 Lipstick compounded raw material compounding ratio (% by weight) Sasa fruit juice oil 10.0 Sasa seed oil 15.0 Castor oil 20.0 Lanolin 5.0 Candelilla wax 8.0 Carnauba wax 8.0 Ozokerite 6.0 Hexadecyl alcohol 20.0 Pigment 8.0 Fragrance, preservative Appropriate amount Preparation method Heat and melt the base material and mix evenly. A pigment is added to this and well dispersed, then remelted, a fragrance is added and defoamed, and the mixture is poured into a mold and rapidly cooled to solidify. Remove the solidified product from the mold and load it into the container. Then, the appearance of the stick was adjusted, and the surface was made uniform by passing through a flame to obtain a lipstick.

The cosmetics obtained in Examples 1, 2, and 3 were all cosmetics having excellent feel and oxidative stability.

Comparative Example 1 4.0% by weight of Sasa fruit juice oil and 2.0% by weight of Sasa fruit juice oil in the blended raw materials of Example 1 were replaced by 6.0% by weight of Sasa fruit juice oil to prepare a similar emulsion.

Comparative Example 2 A milky lotion was prepared in the same manner as in Example 1, except that 4.0% by weight of Sa spine juice oil and 2.0% by weight of Sa spine seed oil were replaced by 6.0% by weight of Sa spine seed oil.

The cosmetics obtained in Comparative Example 1 were excellent in oxidative stability, but had a slightly heavy feel, and the cosmetics obtained in Comparative Example 2 were satisfactory in texture, but were inferior in oxidative stability.

(F) Effect of the Invention The cosmetic of the present invention has an improved quality in that it has an excellent feeling of use, good stability, and an effect of preventing skin aging, as compared with those using conventional fats and oils.
