Description

  The present invention relates to a composition for masking, and more particularly to a composition comprising citronellal, propylene glycol dicaprate, a specific monoester, and a monohydric alcohol having 1 to 3 carbon atoms, the composition comprising paramethoxycinnamic acid It is characterized by having an excellent effect of masking the odor of 2-ethylhexyl.

  Cosmetics are expected to have various efficacy effects, and contain various components. Above all, 2-ethylhexyl paramethoxycinnamate is widely used as an ultraviolet ray protective agent in sunscreens and the like, but may be hydrolyzed due to other components contained, influence over time, and the like. 2-Ethylhexanol produced by this hydrolysis has a strong unpleasant odor, which is a factor that significantly reduces its value particularly in preparations used for the human body such as cosmetics. Normally, it is possible to make a certain odor difficult to understand by including a fragrance component in cosmetics and the like, but since the level of hydrolysis causes a significant unpleasant odor, masking technology is required. come.

  Generally, a masking method is used to make such an unpleasant odor less likely to be perceived by coexisting a fragrance component or the like with a higher intensity. It may lead to a decrease in usability. Thus, many studies have been made on components that can effectively mask unpleasant odors (for example, see Patent Documents 1 and 2). Further, since unpleasant odors vary depending on the structure of the component that is a factor and it is difficult to uniformly mask them, there are reports on masking methods according to the factors of the unpleasant odor (for example, Patent Documents 3 and 4). reference).

  As described above, the unpleasant odor has a difference depending on the structure of the component that is a factor, and it is difficult to uniformly mask the unpleasant odor. Further, in the conventional technique, it was difficult to sufficiently mask the unpleasant odor of 2-ethylhexanol generated by the hydrolysis of 2-ethylhexyl paramethoxycinnamate. Therefore, an object of the present invention is to provide a composition which masks an unpleasant odor of 2-ethylhexanol generated by hydrolysis of 2-ethylhexyl paramethoxycinnamate which is useful in cosmetics. .

  In view of such circumstances, the present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found that citronellal has a high masking effect on the odor of 2-ethylhexyl paramethoxycinnamate. Essential oils containing citronellal and the like have heretofore been known as masking agents.However, when applied to cosmetics and the like, the unpleasant odor may be enhanced by including many other components. We thought that a technique to further enhance the masking effect was necessary. In addition, for that purpose, it was considered that it was necessary to stabilize the state in which 2-ethylhexanol, which causes odor, was mixed with citronellal, and to exhibit an effect as a masking composition. Under these conditions, we examined many cosmetic ingredients and found that combining propylene glycol dicaprate, a specific ester oil, and a monohydric alcohol could enhance the masking effect that cannot be obtained with citronellal alone. It has been found that the masking composition of the present invention has been completed. The obtained composition was a more uniform liquid, and had high applicability as being easily applicable to various agents.

That is, the present invention provides the following components (a) to (d);

  Examples of the external preparation for skin are not particularly limited, and may be, for example, any form of external use gel, cream, ointment, liquid, liniment, cataplasm and the like.

  The masking composition of the present invention can be embodied in various forms such as liquid, gel, cream, solid, powder, mousse, etc. What is sprayed and used in a shape is preferable. The dosage form is not particularly limited, such as a solubilized type, an oil-in-water type, a water-in-oil type, an oil type, a water-in-oil-in-water type, an oil-in-water-in-oil type, and a multilayer type. From the viewpoint of preventing the malodor of 2-ethylhexyl paramethoxycinnamate hydrolyzed when used, an oil-in-water type having a relatively large content of an aqueous component is preferable as a dosage form that is easily hydrolyzed.

  Examples of the environment in which the hydrolysis is likely to occur include shaking the preparation and being in a pressurized state by a propellant or the like.The masking composition of the present invention is used by spraying in a mist state. What is contained in a container that can be used is useful. This is because a mist may be formed when sprayed, and the fragrance may be particularly easily felt as compared with normal use, and the odor of 2-ethylhexyl paramethoxycinnamate may be easily felt. In addition, the container may include one that is sprayed in a mist state by gas filling, but the gas to be filled in this case is not particularly limited, and may be LPG, DME, nitrogen gas, carbon dioxide gas, or the like. Or a mixture of two or more of them.
