Description

TECHNICAL FIELD The present invention relates to a cosmetic composition containing a peach fruit extract.

BACKGROUND ART Conventionally, various investigations have been made as moisturizing agents for external preparations such as cosmetics to prevent drying of skin and hair. Among them, naturally-derived ingredients are known to have various cosmetic effects, and the application of extracts of many plants, fungi, and the like to external preparations such as cosmetics has been studied. Furthermore, in recent years, there is a high demand from consumers for cosmetics containing plant and fruit extracts, and they are widely known because of their high moisturizing effect. For example, a skin cosmetic containing an extract from the fruit of star fruit (Averrhoa carambola L.) as an active ingredient (Patent Document 1), summer citrus, so-called Natsudaidai pericarp or whole fruit, obtained from a combination with pulp Examples include cosmetics containing raw materials (Patent Document 2).

Japanese Patent Application Laid-Open No. 2003-300893 JP 2016-37491 A

However, when the moisturizing agents of the above-mentioned patent documents are contained in cosmetics, there is a problem that the moisturizing effect is not necessarily sufficient because the moisturizing agents are often sticky.

As a result of intensive studies to solve the above problems, the inventors of the present invention found that a cosmetic composition characterized by containing a peach fruit extract can solve the above problems, and completed the present invention. Arrived.

INDUSTRIAL APPLICABILITY The present invention can provide a cosmetic composition having excellent moisturizing properties and less stickiness.

The present invention will be described in detail below. In addition, all the units which show content are the mass % unless otherwise specified.

The present invention is a cosmetic composition characterized by containing a peach fruit extract.

The peach used in the present invention is not particularly limited as long as it is a rose family peach genus peach species (scientific name: Prunus persica) and its synonyms, but examples include white peach, yellow peach, banto, golden peach, nectarine, and oil peach. . Among these, it is preferable to use Bantu, whose commercial value is enhanced by its rarity and topicality.

The peach fruit extract used in the present invention is the fruit part of Prunus persica (scientific name: Prunus persica) belonging to the family Rosaceae. The extraction method is not particularly limited, and for example, it may be extracted with heating or extracted at room temperature. Furthermore, the plant may be extracted as it is, or may be extracted after being dried.

Examples of extraction solvents include water, lower alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, etc.), liquid Valid alcohols (1,3-butylene glycol, propylene glycol, glycerin, etc.), ketones (acetone, methyl ethyl ketone, etc.), acetonitrile, esters (ethyl acetate, butyl acetate, etc.), hydrocarbons (hexane , heptane, liquid paraffin, etc.), and ethers (ethyl ether, tetrahydrofuran, propyl ether, etc.). Polar solvents such as water, lower alcohols and liquid polyhydric alcohols are preferred, and water, ethanol, 1,3-butylene glycol and propylene glycol are particularly preferred. These solvents may be used singly or in combination of two or more.

The extract may be used as an extracted solution, or may be used after concentration, dilution, filtration treatment, decolorization with activated carbon or the like, deodorization treatment, etc., if necessary. Furthermore, the extracted solution may be subjected to a treatment such as concentration to dryness, spray drying, freeze drying, etc., and used as a dried product.

The extract of the present invention is not particularly limited, but includes, for example, WHITE PEACH BIOGREEN (SB) (GREENTECH), Peach Herbasol Extract PG (PF) (Lipoid Kosmetik AG), and the like.

The content of the extract of the present invention is preferably 0.0000015% or more, more preferably 0.00015 to 0.015%, in terms of solids, relative to the cosmetic composition of the present invention. If it is less than 0.0000015%, it is difficult to expect a sufficient effect. When the content exceeds 0.015%, enhancement of the effect is hardly recognized.

The extract of the present invention may be used as it is, and anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, and high-grade surfactants may be used as long as the effects of the extract are not impaired. Alcohol, higher fatty acid, silicone oil, hydrocarbon oil, ester oil, vegetable oil, sequestering agent, UV absorber, fragrance, antioxidant, moisturizer, cooling agent, vitamins, pH adjuster, colorant etc., and one or more of these may be contained.

The cosmetic composition of the present invention may be in any dosage form, for example, emulsions, creams, lotions, lotions, packs, serums, cleansers, makeup cosmetics, and other cosmetics; Various forms of cosmetics such as ointments, powders, granules, aerosols, patches and poultices can be exemplified.

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