Description

[Technical field]

[0001] The present invention relates to a textile product treatment composition and a method for suppressing the generation of odor caused by sebum stains on textile products. [Background technology]

[0002] Dirt such as sweat, sebum, and protein from the human body that adheres to textile products such as clothing is usually removed by washing, but as contamination and washing are repeated, dirt that cannot be removed by washing accumulates. It is known that such accumulated dirt causes odor problems due to bacterial metabolism, and it is common to deal with this by using ingredients such as bactericides in combination. However, it is difficult to suppress odor generation by applying bactericides alone, and in particular, it is difficult to suppress odor generation due to oxidative decomposition of sebum with normal washing or bactericides.

[0003] Patent Document 1 discloses a technology for improving the adsorption amount of an antioxidant to suppress the generation of unpleasant odors due to spontaneous autoxidation, and describes that fibers using elastane promote the adsorption of antioxidants. On the other hand, a technology for applying a silicic acid ester to a textile product treatment agent is known, and Patent Document 2 discloses a liquid softener composition containing (A) a specified silicon compound, (B) a specified cationic surfactant, and (C) a specified hydrocarbon and / or liquid paraffin, and discloses a technology for imparting softness and lingering fragrance to textile products by the liquid softener composition. Patent Document 3 discloses a liquid fragrance composition for spraying that contains (a) a specified silicic acid ester, (b) a deliquescent inorganic salt, and water. Furthermore, Patent Document 4 discloses a deodorant composition containing (A) a specific cationic compound and (B) a specific antioxidant, and discloses a technology for applying microcapsules to a fabric softener containing an antioxidant.

[0005] However, the conventional techniques have not yet achieved sufficient effects in suppressing the generation of odors caused by sebum stains, and there is a need to significantly suppress the generation of odors caused by sebum stains on textile products. Moreover, the techniques described in Patent Documents 2 to 4 merely disclose techniques for antioxidants that prevent the oxidation of components in a composition, but do not disclose techniques for suppressing the generation of odors caused by sebum stains on textile products. The present invention provides a textile product treatment composition for suppressing the generation of odor caused by sebum stains on textile products, and a method for suppressing the generation of odor caused by sebum stains on textile products. [Means for solving the problem]

[0006] The present invention relates to a textile product treatment composition comprising (a) one or more members selected from (a1) a silicate ester represented by the following general formula (a1) and (a2) microcapsules encapsulating a fragrance [hereinafter referred to as component (a)], and (b) one or more members selected from compounds represented by the following general formula (b1) [hereinafter referred to as component (b)]:

[0034] <(a2) component> Component (a2) is a microcapsule containing a fragrance, and when used in combination with component (b), it is possible to impart and retain functional substances such as fragrances in textile products. The term "microcapsules encapsulating a fragrance" refers to a microcapsule in which a fragrance composition is encapsulated. For example, a microcapsule in which a fragrance composition is encapsulated by a known method using a resin as the outer shell (wall material) of the microcapsule can be mentioned.

[0035] The method for preparing the microcapsules encapsulating the fragrance is not particularly limited, and known microencapsulation methods can be used.Specific examples include chemical methods (interfacial polymerization, in situ polymerization, orifice method), physicochemical methods (coacervation), and mechanical / physical methods (air suspension coating, spray drying, high-speed air current impact method).The outer shell of the fragrance microcapsules can be made of various polymeric compounds such as polyurethane, polyamide, melamine resin, urea resin, alginate, gelatin, gum arabic, and starch, as well as inorganic compounds such as silica.

Alternatively, a method may be used in which a monomer that will become a resin for forming the wall material is mixed in water with an emulsifier such as isobutylene-maleic anhydride copolymer or acrylic acid-acrylamide copolymer to prepare a wall material-emulsifier mixture, then emulsify the wall material-emulsifier mixture with the fragrance and an optional diluent or solvent, and add formaldehyde to the emulsion and stir to obtain a slurry of fragrance microcapsules.

[0038] The fragrance used in the microcapsules encapsulating the fragrance may be the fragrance compositions described in JP-A-2006-249326, WO-A-2007 / 038570, and JP-A-2007-314693.

From the viewpoint of ease of production of the capsules, the fragrance compound (a) has a logP value of 2.0 or more, preferably 2.3 or more, and more preferably 2.5 or more, and 6.0 or less, 5.5 or less, and more preferably 5.0 or less.

Cyclopentadecanolide (6.3), cyclohexadecanolide (6.8), and ambrettolide (6.4) are also preferred as fragrances with logP values ​​higher than 6.0 to be encapsulated in capsules. Here, the numbers in parentheses are logP values.

[0041] In the present invention, the logP value is a coefficient indicating the affinity of an organic compound to water and 1-octanol. The 1-octanol / water partition coefficient P is the distribution equilibrium when a trace amount of a compound is dissolved as a solute in a two-phase solvent of 1-octanol and water, and is the ratio of the equilibrium concentration of the compound in each solvent, and is generally expressed in the form of their logarithm logP to the base 10. The logP values ​​of many compounds have been reported, and many values ​​are listed in databases available from Daylight Chemical Information Systems, Inc. (Daylight CIS), etc., so they can be referred to. If there is no measured logP value, it can be calculated using a program such as "CLOGP" available from Daylight CIS. This program outputs the measured logP value, if any, as well as the value of "calculated logP (ClogP)" calculated by the fragment approach of Hansch and Leo.

[0042] The fragment approach is based on the chemical structure of the compound, taking into account the number of atoms and the type of chemical bonds (cf. A. Leo, Comprehensive Medicinal Chemistry, Vol.4, C. Hansch, PG Sammens, JB Taylor and CA Ramsden, Eds., p.295, Pergamon Press,1990). This ClogP value can be used instead of the measured logP value when selecting compounds. In the present invention, if the measured logP value is available, it is used, otherwise the ClogP value calculated by the program CLOGP v4.01 is used.

[0043] The microcapsules of component (a2) may contain a diluent, solvent, or solidifying agent in addition to the fragrance (A). Examples of the diluent or solvent include ethylene glycol, propylene glycol, dipropylene glycol, and glycerin, as well as fatty alcohols, fatty acids, lower alcohols of fatty acids, and glycerin esters.

[0044] The primary average particle size of the microcapsules of component (a2) is preferably 1 μm or more, and 100 μm or less, more preferably 50 μm or less, and even more preferably 20 μm or less. The average particle size of the microcapsules of the present invention is the median diameter determined by a laser diffraction / scattering type particle size distribution analyzer LA-910 manufactured by HORIBA. Note that component (a2) may be partially aggregated to the extent that storage stability is not impaired.
