Abstract

PROBLEM TO BE SOLVED: To obtain a skin cosmetic causing no skin irritancy and having excellent rough skin preventive effect by including vegetation water afforded from olive fruits. SOLUTION: This skin cosmetic contains pref. normally 0.001-10 wt.%, esp. pref. 0.01-5 wt.%, on.a dry basis, of vegetation water afforded from olive fruits. For the vegetation water, an aqueous solution fraction produced in the process of obtaining ordinary olive oil can be used directly, however, it is preferable that it is used in a refined state after removing lipid components, fibrous components, seed crusts and the like as contaminants through filtration or centrifugal separation. This skin cosmetic may be formulated, as necessary, with various ingredients generally used in cosmetic compositions, and can be prepared into any formulation such as ointment, lotion, milky lotion, cream, pack, cataplasm, granules or base makeup.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a skin cosmetic, and more particularly, to a skin cosmetic having no skin irritation and an effect of preventing rough skin.

[0002]

2. Description of the Related Art Olive berries contain about 15 to 30% by weight (hereinafter, referred to as "% by weight", all means mass%) together with about 70% by weight of water together with lipid components. Have been. This olive (Olea euro
The olive oil obtained by pressing the fruits of paea Linne) contains about 25% of solid glycerides such as stearic acid and palmitic acid, and about 75% of liquid glycerides such as linoleic acid and oleic acid. It is widely used in edible oils, cosmetics, soap ingredients, medicinal products, and the like. In the process of producing olive oil, a large amount of water called vegetation water is produced. In other words, it is an aqueous part obtained by pressing olives. About 3% in this vegetation water
It is known to contain about 1% polyphenols with about 1% sugars, about 1% organic acids and about 1% lipids. However, this vegetation water is an unnecessary substance and a waste in the olive oil production process, and its application has not been studied at all.

[0003] The inventors of the present invention have conducted intensive studies on the application of vegetation water, and as a result, have confirmed that the addition of vegetation water can provide a skin cosmetic having an excellent skin roughness prevention effect. The present invention has been completed.

[0004] That is, an object of the present invention is to provide a skin cosmetic which has no skin irritation and has an excellent skin roughness preventing effect.

[0005]

The above object is achieved by containing vegetation water produced in the process of producing olive oil. That is, the present invention resides in a skin cosmetic comprising vegetation water produced in the process of producing olive oil.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The vegetation water used in the present invention can be directly used from an aqueous solution produced in the process of obtaining ordinary olive oil. It is preferable to remove and purify by filtration or centrifugation before use. In addition, after adding alcohols to the aqueous solution for the purpose of suppressing the generation of offensive odor due to contamination of various bacteria, the alcohol is separated by filtration or centrifugation.
Purification is also possible. Further, the obtained vegetation water can be used after being concentrated or dried by an ordinary method.

[0007] The skin cosmetic containing the vegetation water according to the present invention may be, if necessary, various components generally used in cosmetic compositions within a range not impairing its effect, that is, oil components, surface active agents. Agents, humectants, thickeners,
Preservatives, antioxidants, ultraviolet absorbers, fragrances, pigments and the like can be combined and compounded. Skin cosmetics according to the present invention, ointments, lotions, emulsions, creams,
Any dosage form such as packs, haptics, granules, base make-ups and the like can be used. Further, the skin cosmetic of the present invention can also be used as a powder, granule, tablet or liquid bath agent. The skin cosmetic of the present invention can also be used as a detergent such as a soap, a face wash, or a body wash in various forms such as solid, cream or liquid.

The amount of the above-mentioned vegetation water in the skin cosmetic of the present invention varies depending on the purpose and dosage form of the skin cosmetic, and cannot be specified unconditionally. The content is preferably 0.001 to 10% by weight, particularly preferably 0.01 to 5% by weight in terms of dry matter. 0.0
If the amount is less than 01% by weight, the effect of preventing rough skin may be insufficient, and even if the amount exceeds 10% by weight, the effect corresponding to the amount may not be obtained.
