Description

The present invention relates to cosmetics, and specifically relates to carnation flower extracts and cosmetics containing carnation flower extracts whose deterioration odor over time is suppressed.

It is generally known that skin cosmetics contain extract components extracted from plants in hopes of having an effect on the skin. While many of these plant extracts have been approved for use in cosmetics, they are diverse and many have not been studied much.

Such an example is a plant extract derived from carnation flowers. Examples of plant extracts derived from carnation flowers include examples of mucopolysaccharide fragmentation inhibitors containing components extracted from the petals of flowers including carnations as active ingredients (see, for example, Patent Document 1), and Examples of cosmetics using aroma components obtained from aromatic plants including Caryophyllaceae (for example, see Patent Document 2), which combine Asteraceae plants, Gentianaceae, Araceae, or Rutaceae plants, and Caryophyllaceae plants. Examples of hair cosmetics (see, for example, Patent Document 3), examples of compositions having a slimming effect containing fragrances obtained from carnations (see, for example, Patent Document 4), and anti-aging products containing extracts of plants of the genus Dianthus. Examples of such agents (for example, see Patent Document 5) are known.

It is generally known that some of the plant-derived ingredients used in this way deteriorate over time, causing discoloration and odor. In particular, it is generally known that aroma components may change in odor quality over time or produce a deteriorating odor, such as changing to an unpleasant odor.

Although the above-mentioned prior art cosmetics mention their effect on the skin or the comfort provided by aromatic components, sufficient studies have not been conducted on the stability of the cosmetics over time. In addition, there are almost no known examples of evaluating the deterioration odor of extracts extracted from carnation flowers over time. Against this background, there has been a desire for a method for suppressing deterioration odor over time in cosmetics containing extracts extracted from carnation flowers, and for cosmetics in which deterioration odor is suppressed.

The present invention has been made in view of the above-mentioned problems, and its purpose is particularly to suppress deterioration odor of carnation flower extracts and cosmetics containing the extracts over time.

The present inventors conducted extensive research to achieve the above objective, and found that by combining carnation flower extract with extracts extracted from canina rosea and/or rice fruit, the deterioration odor of carnation flower extract over time was reduced. The present invention was completed based on the discovery that this can be suppressed.

The first invention is a deterioration odor suppressing agent or a deterioration odor suppressing method for the following component (A), characterized in that the following component (B) is used as an active ingredient. Preferably, the blending ratio (B)/(A) of components (A) and (B) is 1.0 or more.
(A) Carnation flower extract.
(B) Extract extracted from caninabara and/or rice fruit

A second invention is a cosmetic containing the deterioration odor suppressant, preferably containing component (A) in an amount of 0.01% by weight or more based on the total weight of the cosmetic.

According to the present invention, it is possible to suppress deodorization of carnation flower extracts and cosmetics containing the extracts over time.

Hereinafter, the configuration of the present invention will be explained in detail. The effects of the present invention can be exerted by combining (A) carnation flower extract, which will be described in detail below, with (B) extract extracted from canina rosea and/or rice fruit.

As used herein, "extract" refers to the entire liquid extracted by various extraction techniques. That is, a certain extract contains a solid content of about 0.5 to 10% by weight (hereinafter expressed in weight% unless otherwise specified) and the remaining extraction solvent such as water or ethanol. Generally, this solid content becomes the extract referred to in the cosmetic label name. In particular, the carnation flower extract (A) in the present invention also contains volatile components such as aroma components, making it difficult to evaluate based on the solid content weight. Express in terms of quantity.

In this specification, "degraded odor" refers to the odor of Chinese herbal medicine that deteriorates over time when carnation flower extract is stored at room temperature for a long time, left in a high-temperature environment, or exposed to ultraviolet rays such as sunlight. It has a unique medicinal odor such as creosote or creosote.

<(A) Carnation flower extract>
Component (A) used in the cosmetic of the present invention is carnation flower extract. Component (A) of the present invention is an extract extracted from the petals of carnation (Dianthus caryophyllus L.), and is used as an effect on the skin and as a fragrance.

Component (A) of the present invention can be extracted by directly pressing the flower part of a carnation, by extracting with a solvent such as water, ethanol, 1,3-butylene glycol, or a mixed solution thereof, or by using water vapor. Obtained by methods such as distillation. Ingredient (A) of the present invention contains various components, and it is thought that aroma components are included among them, and it is assumed that this aroma component denatures over time and becomes a cause of deterioration odor. has been done. Component (A) of the present invention is available as a commercially available cosmetic raw material.

When the component (A) of the present invention is used in a skin cosmetic, the amount of component (A) is preferably 0.01 to 1.0% based on the total composition of the skin cosmetic. When it is 0.01% or more, it can exert a sufficient effect on the skin, and when it is 1.0% or less, the carnation-derived aroma is not too strong, and the cosmetic does not feel sticky when used.

<(B) Extract extracted from Caninabara>
One of the components (B) used in the present invention is an extract extracted from Canina rosea. This canina rose is a plant of the Rosaceae family, also called rose hips.

<(B) Extract extracted from rice fruit>
Another component (B) used in the present invention is an extract extracted from rice fruit. Rice is a plant belonging to the Poaceae family, and the "rice fruit" described in the present invention refers to brown rice, white rice, or rice bran obtained when making white rice from brown rice.
