Description

  The present invention relates to a cleaning composition containing a high concentration of catechins and containing a nonionic surfactant as a cleaning component.

Catechins are known to have various actions such as antibacterial activity, antioxidant activity, chemisorption, chelation, and enzyme activity inhibition. is doing. One of the effects is a deodorizing effect.
On the other hand, in recent years, with the improvement of living environment, people's intention for cleanliness has become stronger. In particular, the odor is becoming more sensitive. Major target malodorous components include nitrogen-containing compounds such as ammonia, urea, indole, skatole, and amines, sulfur-containing compounds such as methyl mercaptan, hydrogen sulfide, and dimethyl sulfide, and lower fatty acids such as butyric acid. is there. In addition, there is nonenal called aging odor, which is generated by oxidation and decomposition of tobacco odor containing nicotine and fatty acids in keratinous sebum.
As a method of deodorizing or deodorizing these malodors, a method of masking malodors by using aromatic substances such as jasmine and lemon, a method of adsorbing malodors to those with adsorption performance such as activated carbon, and oxidative decomposition of malodors Chemical decomposition methods that allow or neutralize are used.
Deodorizers, inhibitors and deodorizers using these methods have been proposed. For example, a deodorant composition (see, for example, Patent Document 1) or zeolite that reduces chlorine odor by adding a deodorant, an aromatic substance and a surfactant to an inorganic chlorine compound having a strong chlorine odor. There are used pet excretion treating agents (for example, see Patent Document 2).

  Recently, pets have been kept indoors, and deodorization and deodorization of pet body odors have become a major issue in order to live a comfortable life with pets. In order to solve this problem, various measures are taken. For example, a deodorant drink (see, for example, Patent Document 3) that attempts to suppress the body odor of a pet from the body, a shampoo for pets, and the like are also provided. However, most shampoos for pets mask odors with fragrance components, and the odor of the fragrance components itself is strong, so it is unfavorable when they are offended by the odor or mixed with the body odor of pets. New odor may be offended. Moreover, although there exist some which mix | blend deodorizing components, such as catechins using a chemical decomposition method, since there are few addition amounts, there are many things which cannot experience a deodorizing effect.

As described above, the conventional cleaning composition that exhibits the deodorizing effect is mainly masked with an aroma component, and the deodorizing effect cannot be experienced.
A normal detergent contains an amphoteric surfactant such as alkylbetaine, an anionic surfactant such as alkane sulfonate, and a nonionic surfactant as a base material. In order to increase the viscosity, a method using structural thickening by combining an amphoteric surfactant or salts with an anionic surfactant, or adding a polyacrylic acid-based polymer thickener is performed. Yes. However, blending catechins at a high concentration may cause interaction with these surfactants, leading to precipitation, cloudiness, and a decrease in viscosity. In fact, when catechins were added to a commercially available cleaning agent, a rapid decrease in viscosity could be confirmed. In addition, when catechins are added to the conventional cleaning composition, there is a problem that precipitation occurs, and the product cannot be produced.

Accordingly, the present inventors have intensively studied for the purpose of solving the above-mentioned problems, and as a result, have found a method of blending catechins at a high concentration and completed the present invention.
In other words, in a cleaning composition containing an amount that can fully experience the effects of catechins such as a deodorizing effect, by adding a nonionic surfactant as a base material for a cleaning component, viscosity and deodorizing The stability of catechins having effects and the like can be maintained, and a safe detergent for pet skin and the like can be provided.

  It is possible to maintain the stability of catechins to be blended by using a nonionic surfactant while having sufficient effects of catechins such as excellent deodorizing effect by blending 1% by weight or more of catechins. it can.
