Description

The present invention relates to a fragrance composition for textiles, and more particularly to a fragrance composition for textiles which is excellent in low-temperature stability, aroma persistence and aroma quality of a liquid composition and does not impair the texture of the fiber.

A wide variety of perfume ingredients are blended in the fragrances for textile products such as linen water and pillow mist used by spraying on towels, sheets, pillows, etc., and give olfactory benefits. In the case of fragrance products, alcohol is used as a base, but in the case of fragrances for textile products, a base that does not impair the texture of the fibers must be selected because it is used directly on the fibers. In the case of a water-based composition, the perfume component is solubilized by a perfume solubilizer (surfactant) and alcohol. However, in order to realize a rich and persistent fragrance that has been in increasing demand due to diversification of consumer preferences in recent years, when a fragrance component having a benzene skeleton and an aldehyde group is blended at a high concentration, the fragrance component is reduced at a low temperature. It will precipitate.
For stabilization, it is conceivable to add a large amount of a surfactant or alcohol that is compatible with the fragrance component, but in that case, the fragrance component is less likely to volatilize or the fragrance persistence is reduced. The quality will be impaired and the effect of the scent will not be obtained. In addition, the texture of the textile product may be impaired.
Therefore, there is a need for a fragrance composition for textiles that suppresses the precipitation of perfume ingredients at low temperatures with a small amount of active agent, does not inhibit the fragrance formation, and does not impair the texture of the fiber even in continuous use.

Therefore, in order to solve the above-described problems, for example, in Patent Document 1, liquid stability is achieved by housing a composition containing a nonionic surfactant and alcohol in a resin-coated metal container for a specific combination of fragrances. In addition, a fragrance composition for textiles excellent in fragrance sustainability and aroma stability is disclosed.
In Patent Document 2, a method including a fragrance, a surfactant, and a phase adjuster, which spreads a pleasant scent in a washing tub and enhances the remaining fragrance to clothes after washing, Patent Document 3 includes water, alcohol, and sucrose ester. The method used, Patent Document 4, discloses a method of solubilizing and stabilizing a fragrance with a surfactant and alcohol in a uniform and transparent manner. Patent Document 5 discloses a method of emulsifying or solubilizing a perfume that is insoluble or hardly soluble in water in a polyhydroxyl compound or an aqueous solution thereof in the presence of a protein, a protein degradation product, or a surfactant. A method of adding a hydrophilic solvent / oily oil to a mixture of hiba oil, water, and a hydrophilic surfactant to maintain a uniform mixed state for a long period of time with an emulsified or translucent liquid composition. Has proposed a method of maintaining good storage stability by using EOPO-modified C1-C6 alkanol and a nonionic emulsifier.

However, when a large amount of poorly soluble fragrance is blended as a rich and long-lasting fragrance component, the conventional technology satisfies all of the liquid stability and fragrance stability during storage and the fragrance persistence after spraying the fiber product. It was difficult.

This invention is made | formed in view of the said situation, and it aims at providing the fragrance composition for textiles which is excellent in low-temperature stability, fragrance sustainability, and fragrance quality, and does not impair the texture of a fiber.

As a result of intensive studies to achieve the above object, the present inventors have formulated a specific amount of a fragrance component having a benzene skeleton and an aldehyde group, and further specified a specific nonionic surfactant, ethanol, and water, respectively. It was found that by blending in an amount, a fragrance composition for textiles that is excellent in low-temperature stability, fragrance persistence, and fragrance quality and that does not impair the texture of the fiber can be obtained.

That is, the present invention relates to (a) a nonionic surfactant having 0.0001 to 5.0% by weight of a fragrance component having a benzene skeleton and an aldehyde group, and (b) 10 to 80 mol of an alkylene oxide. Provided is a fragrance composition for textiles containing 01 to 1.0% by weight, (c) 15 to 60% by weight of ethanol and (d) 20 to 80% by weight of water.

According to the present invention, it is possible to obtain a fragrance composition for textiles which is excellent in low-temperature stability, scent sustainability and scent quality, and does not impair the texture of the fiber.

Further, (a) the fragrance component having a benzene skeleton and an aldehyde group is composed of benzaldehyde, phenylacetaldehyde, phenylpropylaldehyde, cinnamic aldehyde, α-amylcinnamic aldehyde, anisaldehyde, cuminaldehyde, piperonal, cyclamenaldehyde, and vanillin. Provided is a fragrance composition for textiles that is one or more selected.

The blending amount of the component (a) in the composition of the present invention is 0.0001 to 5.0% by weight, preferably 0.005 to 5.0% by weight, more preferably 0.001% to the composition. 01 to 5.0% by weight. When the amount is more than 5.0% by mass, the composition causes white turbidity or separation, or a disadvantage that it becomes a stain when used in a textile product. On the other hand, when the amount is less than 0.0001% by mass, the aroma and its sustainability deteriorate.

Specific examples of the component (a) in the composition of the present invention include benzaldehyde, phenylacetaldehyde, phenylpropylaldehyde, cinnamic aldehyde, α-amylcinnamic aldehyde, anisaldehyde, cuminaldehyde, piperonal, cyclamenaldehyde, vanillin and the like. Among them, piperonal is particularly preferable.

The blending amount of the component (b) in the composition of the present invention is 0.01 to 1.0% by weight, preferably 0.05 to 1.0% by weight, more preferably 0, based on the total amount of the composition. 0.1 to 1.0% by weight. When it is more than 1.0% by weight, it causes stickiness and spots when used in textile products. On the other hand, when the content is less than 0.01% by weight, the fragrance cannot be solubilized, and the composition becomes clouded or separated.

The component (b) of the present invention is a nonionic surfactant to which 10 to 80 moles of alkylene oxide is added, preferably the number of moles of alkylene oxide added is 20 to 80, more preferably 40 to 60. The alkylene oxide may be ethylene oxide or propylene oxide, but is preferably an ethylene oxide added. The kind of the nonionic surfactant to which the alkylene oxide is added is not particularly limited, but for example, a hydrogenated castor oil or a nonionic surfactant in which an alkylene oxide is added to a sorbitan fatty acid ester is preferable, and a hydrogenated castor oil is particularly preferable.

The amount of component (c) of the present invention is 15 to 60% by weight, preferably 20 to 50% by weight, more preferably 30 to 40% by weight, based on the total amount of the composition. When it is more than 60% by weight, the base odor of alcohol becomes noticeable when used in textiles, resulting in discomfort. On the other hand, when the amount is less than 15% by weight, the composition causes white turbidity or separation, and when used in a textile product, drying is slow and usability deteriorates.

The fragrance composition for textiles of the present invention contains 20 to 80% by weight of water as component (d). Preferably it is 30-80 weight%, More preferably, it is 40-75 weight%.

In addition to the above components (a) to (d), the fiber product fragrance composition of the present invention can be appropriately mixed with components as long as the effects of the present invention are not hindered, for example, a uniform transparent liquid state In the range which maintains fragrance | flavor components other than said (a) can be contained. Moreover, as other components, antibacterial agents, ultraviolet ray inhibitors, antioxidants such as dibutylhydroxytoluene, and pH adjusters such as acids and alkalis can be used as necessary.

The fragrance composition for textiles of the present invention is desirably prepared as a uniform transparent liquid composition by mixing the above essential components and, if necessary, the above optional components according to a conventional method.

The container for the fragrance composition for textiles of the present invention is not particularly limited and can be appropriately selected depending on the usage form, etc., but considering the usability when applied to textiles, it is of the spray type. A container is suitable, and as a spray container, a dispenser type pump spray container, a trigger spray container (direct pressure or pressure accumulation type), or the like can be used.

The type of the textile product for which the fragrance composition for textiles of the present invention is used is not particularly limited, and for example, cloth products such as sheets, pillow cases, towels, clothing, curtains, carpets, shoes, etc. These fiber products can be used from a variety of natural fibers including plant fibers such as cotton and hemp, and animal fibers such as wool and silk, but also manufactured from chemical fibers such as polyester and nylon.
