Description

  The present invention relates to an aqueous composition for treating textile products.

  A perfume is generally used for toiletry products such as a softener composition (for example, Patent Documents 1 to 3), and a technique for imparting a residual scent to leave a scent in a treated clothing is also known (for example, a patent). References 4-6). Moreover, the softening agent composition containing silicone compounds, such as amino modified silicone, is also known (for example, patent documents 7-14).

  As described in Patent Documents 1 to 3, toiletry products are generally scented, and in recent years, interest in fragrance has increased, and a technique for imparting so-called fragrance that leaves fragrance on clothes after washing and flexible processing has been developed. Yes.

  Patent Document 4 discloses a technique for improving the adsorptivity to clothing including a Schiff base fragrance. Patent Documents 5 and 6 disclose a technique using a fragrance component having a low vapor pressure. According to these technologies, it is possible to leave the scent base fragrance and low vapor pressure fragrance on the clothing, but since it is not possible to leave the fragrance components other than the Schiff base fragrance and the middle or high vapor pressure fragrance, it is great for designing the fragrance. There is a limit. Therefore, there is a strong demand for a technique for leaving the middle or high vapor pressure fragrance in addition to the low vapor pressure fragrance.

On the other hand, it is known to use silicone compounds in toiletry products such as softener compositions. In particular, as described in Patent Documents 7 to 14, softener compositions are widely used for the purpose of imparting a preferable texture to textile products. In particular, Patent Documents 7 and 8 disclose softener compositions containing an amino-modified silicone corresponding to the component (b1) of the present invention, and the publication also contains a fragrance.

Component (a2): a fragrance component having a water / octanol partition coefficient (log P) of less than 3.0 and a vapor pressure at 20 ° C. exceeding 0.01 mmHg [hereinafter referred to as component (a2)]

  The component (a2) is a fragrance component that is relatively easy to evaporate, and usually the fragrance component does not remain in the clothes after washing or softening treatment. On the other hand, the component (a1) is a fragrance component that is relatively difficult to evaporate and that is likely to remain in the clothes after washing and softening treatment and has a residual fragrance property. However, even if the component (a1) remains on the clothing, the fragrance is not good, and the scent is limited.

  Therefore, the present invention uses a fragrance mixture containing the components (a1) and (a2) as the component (a), and has various fragrances with good fragrance due to the harmony of the components (a1) and (a2). Utilizing what is obtained, and further combining with the component (b), leaving the component (a1) on the clothing as in the prior art, the point of poor smell and the type of incense tone is limited, etc. The problem (1) has been solved, and the component (a1) can be made to remain aroma.
