Description

  TECHNICAL FIELD The present invention relates to a treatment composition for a textile product that can be applied to textile products such as clothing to impart flexibility and has a long scent.

The technology that continues the release of fragrance is generally called the long lasting technology. This technique is also used in the technical field, and a softener, a finishing agent, or a treating agent for a textile product containing a fragrance is applied to the textile product to attach the fragrance to the textile product. As the long lasting technique in the technical field, utilization of microcapsules (for example, Patent Document 1), use of a fragrance precursor (for example, Patent Document 2), a combination of specific fragrance components (for example, Patent Document 3), and the like. It has been published.
However, although the technology utilizing microcapsules has a high sustaining effect, it is a technology that breaks the capsules by rubbing the fiber product and emits the scent, and the scent does not last unless the capsules are destroyed. Therefore, the long lasting effect cannot be expected in a situation in which a force sufficient to break the microcapsules is not applied to the fiber product. In addition, the textile product may be damaged by rubbing. When a fragrance | flavor precursor is used, the fragrance of the fragrance | flavor component discharge | released from a precursor continues, but the fragrance | flavor tone of a residual fragrance is limited. In the case of a combination of specific fragrances, the scent of a component called “last note” lasts, but the scent of the remaining scent is limited.

  Therefore, an object of the present invention is to provide a treating agent composition for a textile product that lasts a fresh scent including a top note without rubbing the textile product to which the fragrance is applied.

As a result of intensive studies by the present inventors, the fragrance composition is used as a core material of emulsion particles, and the fragrance emulsion particles using fats and oils as the wall material of the emulsion particles and a cationic compound are used in a rinse treatment. It was found that the fragrance emulsion particles were effectively adsorbed to the fiber product even when the scent was applied, and the scent continued for a long time. That is, the present invention
(A) an aqueous liquid containing emulsion particles obtained by emulsifying and dispersing a mixture of an oil and perfume composition having a melting point of 30 ° C. or higher at normal pressure in water, and
(B) A treating agent composition for textiles containing a cationic compound is provided.

  ADVANTAGE OF THE INVENTION According to this invention, while the fragrance property improves, the processing agent composition for textiles which the fragrance tone of a fragrance | flavor is a fresh fragrance containing a top note can be provided.

[ClogP]
The ClogP value is a value representing a 1-octanol / water partition coefficient P representing a ratio of equilibrium concentrations in 1-octanol and in water in the form of logarithmic logP with respect to the base 10 for a chemical substance. The ClogP value can be obtained by f-method (hydrophobic fragment constant method) by decomposing the chemical structure of a compound into its components and integrating the hydrophobic fragment constants / f values possessed by each fragment (for example, , Clog 3 Reference Manual DaylightSoftware 4.34, Albert Leo, David Weininger, Version 1, March 1994).
Generally, since a fragrance | flavor is so hydrophobic that a ClogP value is large, the fragrance | flavor composition containing many fragrance | flavor components with a small ClogP value is more hydrophilic than the fragrance | flavor composition containing many fragrance | flavor components with a large ClogP value. You can say that. When the ClogP value is within a preferable range, the hydrophilic fragrance component and the hydrophobic fragrance component are combined in a balanced manner, which is advantageous in that the fragrance has a better fragrance balance and higher palatability. is there.
