Description

  The present invention relates to a liquid fragrance composition and a liquid fragrance article.

  In recent years, there has been an increase in the number of clothes that are not washed only by being worn once because of fear of losing shape and fading due to washing, and there is a problem that odors in such clothes are worrisome. On the other hand, the lifestyle habit of positively scenting clothing is spreading for the purpose of enjoying the scent of the clothing being worn. For example, commercially available softener compositions and detergent compositions are sold with products with aromatizing properties on the front. There is a tendency that a more natural scent tends to be preferred as a preference for a scent, and in this case, it is desired that the scent lasts for a long time.

In such applications, various techniques relating to natural fragrances have been studied. For example, Patent Document 1 discloses a fragrance composition having an aroma that gives a feeling of peace by using a specific fragrance and a natural fragrance in combination.
Patent Document 2 discloses a fragrance composition for textiles in which a natural fragrance or the like is contained in a specific container for the purpose of liquid stability and fragrance sustainability.

  Since the natural fragrance is preferred as the scent of the above-mentioned garments, studies using natural fragrances are being conducted. However, natural fragrances are not generally composed of a single compound due to the preparation process, and are often a mixture of a plurality of compounds. Furthermore, since various trace components are mixed, some natural fragrances are aqueous. Some of the compositions are difficult to disperse stably, and it has been found that a product using a fragrance composition containing a natural fragrance has a problem that it is difficult to maintain storage stability. Moreover, it is desired that the fragrance sustainability is good with respect to the fragrance of the textile product.

  An object of the present invention is to provide a liquid fragrance composition that is excellent in storage stability even after being stored for a long period of time and that is excellent in fragrance sustainability regarding the fragrance of a textile product.

  When the present inventors have examined the above-mentioned problem, the liquid fragrance composition has a specific added mole number of propyleneoxy group, ethyleneoxy group and hydrocarbon group which have strong properties as a natural fragrance and an oil agent. By using an ionic surfactant in combination with other nonionic surfactants, the storage stability in the composition can be maintained even when natural fragrances are used, and the fragrance sustainability is improved. As a result, the present invention has been completed.

In the present invention, (a) a fragrance composition containing a natural fragrance is 0.01% by mass or more and 0.5% by mass or less, and (b) a nonionic surfactant (except for the component (c)) is 0.01. It is related with the liquid fragrance | flavor agent composition containing 0.01 mass% or more and 1 mass% or less of the compound represented by the following formula (c1), and water.
