Description

[Technical Field]

[0001] The present invention relates to a liquid fragrance composition, particularly to a liquid fragrance composition for textile treatment products. [Background technology]

[0002] When using products such as fabric softeners, detergents, and spray-type textile treatment agents, consumers have a need to enjoy a variety of scents and strengths, and Patent Documents 1 and 2 are known as prior art. In order to provide a variety and intensity of fragrances that suit the consumer's preferences, one possible method is for the consumer to mix a fragrance composition into an unscented composition by themselves. However, when a fragrance is added to a fabric softener or a fabric spray, it is preferable to mix the fragrance with the fabric softener or fabric spray uniformly, but depending on the composition of the fragrance, it may not be possible to mix it well with the fabric softener or fabric spray.

[0015] The content of component (A) in the liquid flavoring composition of the present invention is not particularly limited as long as the blending purpose can be achieved, but is preferably 1 to 90 mass %, more preferably 5 to 80 mass %, even more preferably 20 to 70 mass %, and particularly preferably 30 to 60 mass %, relative to the total mass of the liquid flavoring composition. When the content of component (A) is 10 mass % or more, the liquid flavoring composition of the present invention, when blended in a fabric treatment product, exhibits better fragrance retention.

[0016] [(B) Component] In the liquid fragrance composition of the present invention, component (B) is an alkylene oxide-added nonionic surfactant, and is incorporated to improve the solubility of component (A) in a composition for a spray product, which is a homogeneous system containing a large amount of water or ethanol. Examples of alkylene oxide adduct nonionic surfactants that can be used include those derived from polyhydric alcohols, higher alcohols, higher amines, or higher fatty acids. Specific examples include polyoxyalkylene glycerin fatty acid esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene sorbitol fatty acid esters, polyoxyalkylene sucrose fatty acid esters, polyoxyalkylene pentaerythritol fatty acid esters, polyoxyalkylene castor oil, polyoxyalkylene hydrogenated castor oil, polyoxyalkylene alkyl ethers, polyoxyalkylene alkylphenyl ethers, polyoxyalkylene alkylamines, and polyoxyalkylene fatty acid amides. Here, "oxyalkylene" refers to an alkylene oxide adduct. Component (B) is preferably a nonionic surfactant having an average of 2 to 100 moles of alkylene oxide added per molecule, more preferably 5 to 80, even more preferably 10 to 60, particularly preferably 20 to 50, and most preferably 20 to 40. An average number of moles of alkylene oxide added of 100 or less can provide better compatibility with emulsifying softeners, while an average number of moles of alkylene oxide added of 2 or more can inhibit plastic degradation. While the exact mechanism of action is unknown, a characteristic of components that cause plastic degradation is that they have a certain level of hydrophobicity. Components with low hydrophobicity have low compatibility with plastics and do not penetrate into the plastic, making them less likely to cause degradation. Therefore, it is believed that components with low hydrophobicity, such as nonionic surfactants with two or more added alkylene oxides, which are described as preferred components of the present invention, can inhibit plastic degradation. The alkylene oxide is preferably an alkylene oxide having 2 to 4 carbon atoms, more preferably ethylene oxide or propylene oxide, and particularly preferably ethylene oxide.

Here, "POE" represents polyoxyethylene, "POP" represents polyoxypropylene, and the numbers in parentheses after each represent the average number of moles added. Also, "EO" represents ethylene oxide, and the number before it represents the number of moles added of EO. The component (B) may be used alone or in combination of two or more types.

Furthermore, depending on the composition of component (A), it may cause deterioration of plastics, etc., and when the fragrance is stored in a plastic container, the container may deteriorate, making it difficult to close the lid, or it may affect the deterioration of the dropper used to draw up the fragrance. However, component (B) is effective in suppressing the deterioration of plastics, etc., caused by component (A). In the alkylene oxide adduct of a polyhydric alcohol fatty acid ester, the number of carbon atoms in the fatty acid is preferably 8 or more, more preferably 14 or more, and preferably 22 or less, more preferably 18 or less.

An example of the use of the liquid fragrance composition of the present invention by mixing it with a fabric softener is the following two-step procedure. Step 1: Mixing the softener composition and the liquid fragrance composition directly at the washing machine inlet or in advance in a separate container such as a measuring cap to form a single fabric treatment composition. Step 2: A step of dissolving the fiber treatment composition of Step 1 in rinse water during the rinsing stage of laundry (a single-rinse detergent may be used, in which case it is the first rinse stage) to soften the textile product. Alternatively, a step of dissolving the composition in water in a container such as a basin, and then placing the textile product in the container for immersion treatment. The amount of softener composition added / the amount of liquid fragrance composition added is not particularly limited, but is preferably 1-500, more preferably 10-100, and even more preferably 20-80.

[0035] In addition, an example of using the liquid fragrance composition of the present invention by mixing it with a spray for fabric treatment is to add the liquid fragrance composition to a liquid composition (composition for spray products) filled in a spray-type container and mix them to obtain a fragranced spray for fabric treatment. The liquid fragrance composition and the liquid composition (composition for spray products) may be mixed in advance in a separate container rather than in the spray-type container, and the mixed composition may be filled into the spray-type container. The amount of liquid agent composition / liquid fragrance composition added for a fiber treatment spray is not particularly limited, but is preferably 1 to 5,000, more preferably 10 to 3,000, and even more preferably 10 to 1,000. It is usually difficult to mix a fragrance composition into a spray composition for textile treatment, which is a homogeneous solution containing water and a solvent such as ethanol, but the fragrance composition of the present invention can be mixed in a wide range of mixing ratios as described above.

[0036] (Softener composition) The softener composition into which the liquid fragrance composition of the present invention can be mixed is not particularly limited, and may be any composition containing a softening base material that is a cationic surfactant. For example, it is preferable in terms of compatibility between the softener composition and the liquid fragrance composition of the present invention that the softening base material is at least one compound selected from the group consisting of amine compounds having 1 to 3 hydrocarbon groups having 10 to 26 carbon atoms in the molecule, which may be interrupted by an ester group or an amide group, their salts, and their quaternized products. The softener composition may contain, without particular limitation, components known in the field of softener compositions, such as nonionic surfactants, inorganic salts, preservatives, and fragrances. In addition, the softener composition is preferably unscented / lightly scented from the viewpoint of the effect on the fragrance imparted by the fragrance composition of the present invention.

[0037] (Textile treatment spray) The spray agent for textile treatment (composition for spray products) with which the liquid fragrance composition of the present invention can be mixed is not particularly limited, and may be any agent used for textile treatment. For example, a spray agent for textile treatment containing a nonionic surfactant, particularly an alkylene oxide-added nonionic surfactant, is preferred in terms of compatibility between the spray agent for textile treatment and the liquid fragrance composition of the present invention. The spray agent for fiber treatment can use, without any particular limitation, components known in the field of spray agents for fiber treatment, such as solvents, aromatic alcohols, fragrances, antibacterial agents, bittering agents, etc. Furthermore, the spray agent for treating fabrics is preferably unscented / mildly scented from the viewpoint of the effect on the fragrance imparted by the fragrance composition of the present invention.
