Description

  The present invention relates to a textile product treating agent composition.

In recent years, with the increase in consumer hygiene, not only the appearance of dirt but also the odor reminiscent of the presence of dirt has been strongly desired. Among them, urine odor is regarded as a problem among the odors of living environment given to humans.
On the other hand, the number of care recipients is increasing due to aging. As a problem related to care, when urine adheres to clothing such as underwear, urine odor is emitted from the clothing. Moreover, it is known that the person to be cared for has strong sebum and body odor.
Various compositions for suppressing urine odor and sweat odor have been proposed. For example, Patent Literature 1 and Patent Literature 2 disclose a method for suppressing the generation of urine odor with a β-glucuronidase inhibitor. Patent Document 3 discloses a sweat odor generation inhibiting composition containing a β-glucuronidase inhibitor and (b) one or more selected from a surfactant and a solvent.

The fatty acid composition obtained from beef tallow, palm oil and sunflower oil is preferable from the viewpoint of suppressing urine odor and sweat odor. Further, since these contain a large amount of alkenyl groups having two or more carbon-carbon unsaturated bonds, for example, crystallization as described in JP-A-4-306296 or JP-A-6-41578 The ratio of fatty acids containing two or more carbon-carbon unsaturated bonds can be obtained by performing distillation under reduced pressure as described in JP-A-8-99036 or by performing a selective hydrogenation reaction described in JP-A-8-99036. It can be manufactured by a controlling method or the like. For example, hardened beef tallow is a fatty acid derived from beef tallow saturated by hydrogenation, and may be expressed as semi-hardened as partially cured. In addition, by arbitrarily mixing these curing grades and uncured fatty acids, the fatty acids are not only effective in suppressing urine odor and sweat odor, but also excellent in ease of use such as low viscosity in production.

The progress of the reaction is confirmed by measuring the acid value (AV) and saponification value (SV) by the method described in JISK0070-1992, and preferably AV is 10 mgKOH / g or less, preferably 6 mgKOH / g or less.

On the other hand, since the amine of the fatty acid monoester structure is easily quaternized, the content in the reaction product is usually 0.5 parts by mass or less with respect to 100 parts by mass of the component (A-1). Furthermore, the triethanolamine and the quaternized product of triethanolamine which were not fatty acid esterified contained in total 0.5 parts by mass or more and 3 parts by mass or less with respect to 100 parts by mass of component (A-1), 90 mass% or more is a quaternized product.
