Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perfume retaining agent made of phospholipid, and a fragrance cosmetic containing the same.

[0002]

2. Description of the Related Art In the field of cosmetics for fragrances containing fragrances such as perfume, eau de parfum, eau de toilette and eau de cologne in a high concentration, the scent quality due to the difference in volatility of fragrance components contained in these cosmetics Change was one of the major problems for perfume designers in controlling the quality of the scent. Also, for those who use cosmetics for fragrance, in choosing that,
This is a very inconvenient because the effect of the fragrance that can be produced by these fragrances will change significantly depending on whether you choose the scent immediately after applying the cosmetic or the scent after applying the cosmetic for a while. It was happening. That is, the appearance of cosmetics for fragrances that do not change with time or that change little with time has long been awaited. Further, a cosmetic for a fragrance which has a long-lasting scent once applied has also been desired. A lot of studies have been made by perfume engineers to solve these problems.

As a result, for example, as a method for suppressing the change of the fragrance of a fragrance with time, a fragrance having a strong residual odor such as musk has come to be used. However, if a fragrance having a strong residual odor is used, the fragrance of the whole fragrance is made uniform, and the degree of freedom of fragrance is lost. That is, the reality is that no method has been found to reduce the change of the fragrance with time or to improve the retention of the fragrance.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and is for a fragrance-holding agent and a fragrance containing the fragrance-holding agent, which suppresses the change with time of the fragrance to improve the retention of the fragrance. The task is to provide cosmetics.

[0005]

[Means and Actions for Solving the Problems] Based on the above situation, the inventors of the present invention have conducted earnest research as a result of seeking a substance that suppresses the change with time of the fragrance of the fragrance and improves the retention of the fragrance.
The inventors have found that phospholipids, especially egg yolk lecithin and soybean lecithin, have a strong action, and completed the present invention.

That is, the fragrance-retaining agent of the present invention comprises a phospholipid, and the fragrance cosmetic of the present invention contains the fragrance-retaining agent together with the fragrance. Hereinafter, the present invention will be described in detail. <Fragrance Retaining Agent> The fragrance retaining agent of the present invention is composed of phospholipids as described above. Here, the phospholipid is not particularly limited, but soybean lecithin, egg yolk lecithin, phosphatidylglycerol, phosphatidylinositol, phosphatidylcholine, phosphatidic acid and the like are preferable. The most preferable of these are egg yolk lecithin and soybean lecithin obtained from natural products. This is because these two substances are remarkably excellent in the feeling of use and the ability to retain the fragrance, and thus the change in the scent with time can be significantly reduced. When used in a fragrance composition such as a fragrance cosmetic, the amount of the fragrance-retaining agent of the present invention is preferably 0.05 to 100% by weight based on the total amount of the fragrance. If the amount is too small, the volatilization of the fragrance cannot be suppressed, and it may not be possible to suppress the change of the fragrance with time.If the amount is too large, the fragrance may not be emitted well, or the residual feeling on the skin may become strong, or This is because there may be a defect that stains may be easily formed on the clothes. A more preferable amount used is 0.5 to 10%. <Cosmetics for fragrances> In the present invention, the cosmetics for fragrances means cosmetics for the purpose of adhering the scent to the body for a long time.
0% by weight). This fragrance cosmetic composition is composed of a fragrance, the fragrance-holding agent, and optional components usually used in fragrances. Specific examples of the product form include perfume (or blended fragrance), eau de parfum, eau de toilette, eau de cologne, kneaded aroma, and the like. Among these, the effects of the present invention are most prominent in liquid products such as perfume, eau de parfum, eau de toilette, and eau de cologne, which have conventionally had the most severe fragrance changes with time. The amount of the fragrance may be the same as usual,
0.05 to 100% by weight of one or more of the above fragrance-holding agents can be used with respect to one or more of this fragrance. The blending amount of the fragrance-holding agent is 0.001 to 0.001 by weight based on the total amount of the cosmetic.
5% is preferable. This is because if the amount is too small, the holding power of the fragrance becomes too small, and it may not be possible to suppress the change of the fragrance with time.If the amount is too large, the fragrance may not be emitted well, or the residual feeling on the skin may become strong. Or, it is because defects such as easy stains on the clothes may appear. A more preferable blending amount is 0.05 to 0.1% by weight based on the total amount of the cosmetic.

Examples of the optional component include water, solvents such as alcohols (eg ethanol and propanol), activators, polyhydric alcohols, animal and vegetable oils and the like, which are generally used in cosmetics. It is particularly preferable that the fragrance cosmetic contains a polyhydric alcohol. In this case, the polyhydric alcohol exerts a synergistic effect together with the fragrance-holding agent as a fragrance volatilization inhibitor, and imparts a fragrance-holding power to the cosmetic composition that is even better than that of the cosmetic composition containing the fragrance-holding agent alone. Can be further reduced over time. Such a polyhydric alcohol may be an organic compound having 2 to more than 2 hydroxyl groups in the molecule and having 2 to 6 carbon atoms, such as propylene glycol (PG), 1,3-
Butanediol (13BG), glycerin (GL), diglycerin (DGL), dipropylene glycol (DP)
G), ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG),
Pentyl glycol (PGL), neopentyl glycol (NPGL), erythritol (ET), threitol (TH) and the like are preferable. Most preferred of these are propylene glycol and 1,3-butanediol. This is because these two are remarkably excellent in the feeling of use and the ability to retain the low boiling point fragrance, and thus the change in the scent with time is extremely small. The amount of polyhydric alcohol used is
20 to 300% by weight is preferable with respect to the total amount of the fragrance in the composition. This is because if it is too small, it is not possible to suppress the volatilization of the fragrance, and it may not be possible to suppress the change of the scent with time.
This is because the fragrance may not be emitted well, the feeling of being left on the skin may be increased, and the blemishes may be easily formed on the clothes. A more preferred amount used is 30-40% by weight.

The fragrance cosmetic composition of the present invention exhibits a remarkable effect that the fragrance is highly emitted and the fragrance is retained for a long time even in a system containing a high concentration of ethanol as in the general fragrance cosmetic composition. However, it is possible to exert a remarkable effect also in a system containing no ethanol. This is because phospholipids have excellent solubilizing ability and fragrance releasing action. Thus, it can be said that the present invention can provide a cosmetic for fragrance that does not use ethanol, which is very significant from the viewpoints of safety and environment.
