Description

  The present invention relates to a fragrance composition.

  The scent is an important element that produces a high-class feeling of the preparation, an expectation for the effect, and a psychological sense of security. Currently, fragrances that produce a fragrance are often used in formulations, but the fragrances are often oil components that are insoluble in water. For example, if a fragrance is solubilized with a small amount of an active agent in order to obtain a transparent and water-based preparation such as fragrance or mist, the oil components of the fragrance are likely to associate with each other and cream, and the long-term stability of the preparation is improved. May be reduced. On the other hand, when the fragrance is solubilized with a large amount of the active agent, stickiness during application with the active agent occurs, and further, the volatilization of water and the fragrance increases the concentration of the active agent in the preparation, resulting in long-term stability. May be reduced.

  Patent Document 1 improves the temporal stability of an external preparation such as a cosmetic containing an alkylene oxide derivative, a fragrance, and / or vitamin E or a derivative thereof, and water and optionally other vitamins. On the other hand, a stable external preparation is proposed. However, since the amount of the active agent relative to the fragrance is large, the amount of the active agent around the fragrance component is increased when solubilized, so that the fragrance of the fragrance may be suppressed. Furthermore, the prescription of the formulation which uses many fragrance | flavors for the improvement of sustainability and the improvement of fragrance is increasing, and in patent document 1, there exists a possibility that the request | requirement of solubilizing many fragrance | flavors cannot be satisfy | filled.

  Patent Document 2 proposes a composition of a fragrance, a silicone oil, and a hydrophilic surfactant as an aqueous fragrance excellent in use feeling and emulsion stability and suitable for use in a dispenser. Although the amount of the active agent relative to the fragrance is small, since the fragrance is emulsified with a high-pressure homogenizer, if it cannot be used depending on the compounding components, the preparation cost of the preparation may be high. Furthermore, since it is an emulsification prescription, it may not be possible to obtain a highly transparent aqueous preparation for improving the added value of the preparation.

  Hereinafter, the component (A), the component (B), the component (C), the component (D), the component (E), water, and other optional components in the fragrance composition of the present invention will be described in order.

<Perfume (component (A))>
The present invention is characterized in that a fragrance is used as the component (A). Examples of the fragrances include natural fragrances obtained from animals or plants, synthetic fragrances produced by chemical compatibility means, and blended fragrances that are mixtures thereof, and are not particularly limited. In the present invention, any one or two or more of these fragrances can be used depending on the intended product.

  Examples of fragrances used include hydrocarbons, alcohols, phenols, aldehydes, ketones, acetals, ethers, esters, carbonates, lactones, oximes, nitriles, Schiff bases, amides , Nitrogen-containing compounds, sulfur-containing compounds, natural essential oils and natural extracts.

<Alkylene oxide derivative (component (B)>
One feature of the present invention is that an alkylene oxide derivative represented by the formula (1) is used as the component (B). Only 1 type may be used for a component (B) and it may use 2 or more types together. By the combination of component (B), component (C), component (D) and component (E), component (A) can be solubilized in the perfume composition with a low concentration of active agent. As a result, it is possible to obtain a fragrance composition having excellent fragrance during use and excellent long-term stability.

  The cloud point of the 5 mass% aqueous solution of a component (B) shall be 15 degreeC or more. When the cloud point of the 5% by mass aqueous solution of the component (B) is less than 15 ° C., the long-term stability of the fragrance composition may be deteriorated. From this viewpoint, the cloud point is set to 15 ° C. or higher, preferably 20 ° C. or higher, more preferably 25 ° C. or higher, and most preferably 35 ° C. or higher.

  The cloud point is defined in JIS K 3211 “Surfactant Terms” as “the temperature at which whitening starts when the temperature of the surfactant aqueous solution is raised” and is measured by the following method. . After putting a 5 mass% aqueous solution of component (B) in a test tube to a height of about 40 mm, put a thermometer in this tube and stir well with the thermometer to a temperature about 2-3 ° C. higher than the temperature at which clouding occurs. The temperature at which the mixture becomes warm, is cooled with air again with good stirring, and becomes transparent can be measured as a cloud point. Also, when the aqueous solution is cloudy at room temperature, cool with good stirring until the aqueous solution becomes transparent, gradually warm to the temperature at which cloudiness occurs with good stirring, and then gradually The temperature when cooled and becomes transparent can be measured as the cloud point.

  Z in Formula (1) is a residue obtained by removing all hydroxyl groups from a C 2-7 polyhydric alcohol having 2 to 4 hydroxyl groups. As a C2-C7 polyhydric alcohol which has 2-4 hydroxyl groups, a hydroxyl-containing hydrocarbon is preferable and a hydroxyl-containing saturated hydrocarbon is especially preferable.

  Moreover, as a C2-C7 polyhydric alcohol which has a 2-4 hydroxyl group, a C1-C2 alkyl glucoside is especially preferable. The “C1-C2 alkyl glucoside” means an ether in which the hydrogen atom of one of the hydroxyl groups of glucose is substituted with a C1-C2 alkyl group. As the alkyl glucoside having 1 to 2 carbon atoms, methyl glucoside is particularly preferable.

Are included in component (B) of the present invention.

  Unlike the component (B) of the present invention, when an alkylene oxide derivative in which PO and EO are bonded in a block form is used, the long-term stability of the cosmetic composition may be reduced, and the stickiness at the time of application may be reduced. May occur.

  Content of the component (B) in a fragrance | flavor composition shall be 0.1-15.0 mass%. When the content of the component (B) is less than 0.1% by mass, it is difficult to solubilize the component (A), and the long-term stability of the fragrance composition may be reduced, so the content of the component (B) Is 0.1% by mass or more, preferably 0.5% by mass or more, and more preferably 1.0% by mass or more. Further, if the content of the component (B) exceeds 15.0% by mass, stickiness may occur during application of the fragrance composition, so the content of the component (B) is 15.0% by mass or less. However, 12.0 mass% or less is preferable, and 10.0 mass% or less is still more preferable.

  Component (B) can be produced by a known method. For example, a C2-C7 polyhydric alcohol (Z- (OH) a: for example, a saturated hydrocarbon alcohol or C1-C2 alkyl glucoside) having 2 to 4 hydroxyl groups is used as a starting material. And after adding ethylene oxide and propylene oxide to a starting material at random, a C4 alkylene oxide can be added, and a component (B) can be manufactured.
