Description

FIELD OF THE INVENTION The present invention relates to liquid fabric softener compositions. Specifically, the present invention relates to a liquid fabric softener composition with excellent deodorizing and deodorizing performance.

One of the drivers of the fabric softener market, which has grown significantly, is fabric softeners with deodorizing and deodorizing effects. Consumers are concerned about the smell of their clothes, and the need for deodorizing and deodorizing products is expected to continue into the future. Among these, the half-dried odor that occurs when drying in a room-drying environment is an important odor type, and there are technologies related to this odor.
For example, Patent Document 1 describes that room drying odor can be suppressed by using an antibacterial compound having a specific phenolic structure. Patent Document 2 discloses that by combining two specific quaternary ammonium salts with calcium and magnesium under specific conditions, M. It is described that it suppresses the growth of Moraxella osloensis and imparts antibacterial and deodorizing effects to clothing. Regarding quaternary ammonium salts, a patent document discloses a technique for improving the storage stability of fabric softeners and the dispersion stability of capsule fragrances (which also contribute to deodorizing performance) by incorporating quaternary ammonium salts. 3 and Patent Document 4 are known.

Japanese Patent Application Publication No. 2021-107590 JP 2017-31532 Publication Japanese Patent Application Publication No. 2015-4145 Japanese Patent Application Publication No. 2015-227515

However, consumers' concerns about odor related to clothing have not been completely resolved, and further improvements in performance are desired. Furthermore, cationic base materials such as quaternary ammonium salts may generate odor originating from the base material, which may create a trade-off with the performance of the base material.
Therefore, it is an object of the present invention to provide a liquid softener composition that has deodorizing and deodorizing effects against half-dried odors and can suppress odors originating from base materials.

Among these, habanolide, ambroxan, galaxolide, isoesuper, and tonalide are more preferred.

The ClogP value is the value of the 1-octanol/water partition coefficient P, which represents the ratio of the equilibrium concentrations of a chemical substance in 1-octanol and water, expressed in the form of logarithm logP to the base 10.
The ClogP value can be determined by decomposing the chemical structure of a compound into its constituent elements using the f-value method (hydrophobic fragment constant method) and integrating the hydrophobic fragment constants and f-values of each fragment (for example, Clog 3 Reference Manual Daylight Software 4.34, Albert Leo, David Weininger, Version 1, March 1994).
In general, the larger the ClogP value of a fragrance, the more hydrophobic it is. Therefore, a fragrance composition containing a large amount of fragrance components with a small ClogP value is more hydrophilic than a fragrance composition containing a large amount of fragrance components with a large ClogP value. You can say that.

[Viscosity of liquid softener composition]
The viscosity of the softener composition of the present invention is not particularly limited, but from the viewpoint of usability, separation stability of the softener liquid, and dispersion stability of the functional particles, the TI (thixotropy index) value measured as below is It is preferable that the viscosity is 2.0 or more, and that the viscosity at a rotational speed of 30 rpm at 25° C. is 1 to 1000 mpa·s.
Here, the TI value refers to the following viscosity values after 10 rotations at rotational speeds of 6 rpm and 60 rpm for each composition adjusted to 25°C using a B-type viscometer (manufactured by TOKIMEC, rotor No. 2). This is a value calculated based on the formula. This TI value measures the dependence of viscosity on shear rate (viscosity meter rotation speed) and is used as an index representing thixotropy.
TI value = (6 rpm viscosity value) / (60 rpm viscosity value)

The above TI value is 1 in the case of a Newtonian fluid such as water whose viscosity does not change even if the shear rate changes. When the TI value is greater than 1, it indicates that the liquid has a higher viscosity when the shear force is smaller than when the shear force is large, and the liquid has thixotropic properties.
In the liquid softener composition of the present invention, the range of the TI value indicating thixotropy is preferably 2.0 or more, more preferably 2.0 to 5.0, and even more preferably 2.5 to 4.0. . When the TI value is 2.0 or more, excellent thixotropy is obtained, and the dispersion stability of functional particles such as capsule fragrances is further improved. On the other hand, when it exceeds 5.0, thixotropy increases, which may cause problems such as difficulty in taking out the composition into the cap when measuring the liquid softener composition.
Furthermore, when the liquid softener composition of the present invention has a viscosity in the range of 1 to 1000 mpa·s at 25° C. and 30 rpm of the viscometer, the usability and separation stability of the softener liquid is improved. The properties and dispersion stability of the functional particles are improved.
