JP5412101B2 - Liquid detergent composition for hard surfaces - Google Patents

Description

  The present invention relates to a liquid cleaning composition for hard surfaces.

  In general, cleaning agents for hard surfaces have compositions suitable for each of them in order to remove different stains to be treated, such as bathrooms, kitchens and floors. For example, kitchen cleaners used around kitchens such as ovens, ovens, walls and floors around the range, and exhaust fans are used to remove oil stains that have been altered by the action of heat, sunlight, oxygen in the air, etc. A cleaning agent containing an activator, a solvent, an alkali agent and the like is used. Also, as bathroom cleaners used in bathrooms such as bathtubs, bathroom walls and floors, metal soaps, especially detergents containing detergents, metal ion sequestering agents, etc., are used to remove dirt from fatty acid calcium salts. The agent is used. Such detergents are often adjusted to be alkaline with a pH of 10 or higher in order to exhibit high cleaning performance. Patent Document 1 describes a liquid detergent composition suitable for a hard body containing a specific glyceryl ether mixture, a surfactant, a builder, and an alkaline agent, and describes that the pH can be made alkaline. ing.

  Further, due to the recent increase in hygiene awareness and cleanliness, the sterilization action by using a cleaning agent is strongly desired. Although the cleaning agent originally has the effect of physically washing and removing the bacteria, there is a limit to removing the bacteria attached to the uneven surface such as fine scratches on the surface only with physical force. Therefore, it is preferable to add a disinfectant to the cleaning agent. In this case, the most effective compound as a disinfectant is a cationic surfactant. Cationic surfactants are widely used in the hygiene field and the like because of their broad antibacterial spectrum and rapid action. However, when the cationic surfactant is used in combination with a surfactant other than the cationic surfactant, which is a cleaning component, various disadvantages occur. For example, when combined with an anionic surfactant, the bactericidal efficacy of the cationic surfactant is deactivated. For this reason, many nonionic surfactants must be used as a co-surfactant, which changes the foam quality. On the other hand, in combination with a nonionic surfactant or an amphoteric surfactant, the bactericidal efficacy of the cationic surfactant is often retained, but the foaming power is impaired by the influence of the cationic surfactant. Therefore, in order to compensate for this, the total amount of the surfactant is increased, which not only causes economic inconvenience but also results in a decrease in the bactericidal efficacy of the composition.

Methods for solving these problems have been disclosed so far. According to Patent Document 2, a composition comprising an organic solvent in which an interfacial tension at 20 ° C. of a 0.1 wt% aqueous solution is 70 dyn / cm, a surfactant, a bactericide, and water is disclosed. The composition of Patent Document 2 is particularly characterized in that it has excellent hard surface cleaning performance, foam stability and foam retention, and good sterilization performance. In Patent Document 3, without adding a glyceryl ether or diglyceryl ether having an alkyl or alkenyl group having 4 to 12 carbon atoms to the combination of a nonionic surfactant and a cationic surfactant, the bactericidal activity is not lowered. A composition capable of giving excellent foaming properties and feeling of use is disclosed.

  However, even with these methods, the sterilization effect, the foaming performance and the cleaning performance cannot be said to be sufficient. In particular, when washing floors and walls made of ceramics, concrete, metal, plastics, etc. in kitchens and workplaces, they will be diluted with water that already exists, so it is necessary to demonstrate sterilization performance even in a diluted state. . Therefore, in the case of adding a cationic surfactant to the surfactant system as a main cleaning agent, development of means for obtaining excellent bactericidal efficacy and improving foaming performance and cleaning performance has been eagerly desired.

  This invention makes it a subject to provide the liquid detergent composition for hard surfaces which is excellent in foaming power and cleaning power, and has the outstanding bactericidal effect.

  Usually, arylsulfonic acids (and salts thereof) and arylcarboxylic acids (and salts thereof) having about 6 to 10 carbon atoms are often added to the detergent composition as a hydrotrope. However, the above-mentioned aryl group-containing compound is added for the purpose of reducing the viscosity in a high-concentration surfactant system in which the surfactant concentration is 10% by mass or more, and ionic surfactants and inorganic salts. In general, it is added for the purpose of improving the low-temperature stability in a composition having a high ionic strength such as a mixed system. For this reason, in the surfactant system in which a nonionic surfactant or an amphoteric surfactant is used as a main surfactant as in the present invention and the blending amount is 10% by mass or less, the above aryl group is used. The use of contained compounds is generally not carried out (to the extent that it is known to add benzoic acid or its salts for preservative purposes). Under such technical background, the present inventors have formulated a combination of a cationic surfactant and an aryl group-containing compound in an alkaline detergent composition containing a nonionic and / or amphoteric surfactant. Thus, the present invention has succeeded in imparting bactericidal properties to the cleaning agent and combining high cleaning performance and foaming power.

  The liquid detergent composition for hard surfaces of the present invention has not only a high bactericidal effect, but also has a particularly remarkable effect of having excellent foaming power and cleaning power. The reason why such a remarkable effect is manifested is not clear, but is thought to be based on the following mechanism. That is, when the component (c) is added to the micelle composed of the component (a), the strength of the ionic repulsion of the hydrophilic group portion in the component (c), and the benzyl group or lower group bonded to the nitrogen of the hydrophilic group portion It is considered that the micelle structure tends to be sparse due to the size of steric hindrance due to alkyl groups. However, the addition of the component (d) not only weakens the ionic repulsion, but also reduces the mobility of the hydrophilic group of the component (c) due to the hydrophobic interaction between the aryl groups of the component (d). Can be considered. Due to the above interaction, the addition of the component (d) causes the micelle structure to become dense, and as a result, the foam film stability is increased, leading to an improvement in foaming power. Moreover, it is thought that emulsification dispersibility increases and the detergency improves because the micelles become dense. Moreover, although it is thought that a micelle becomes sparse by adding (a) component and (c) component, it has a long-chain alkyl group different from (d) component as an anionic component for making a micelle dense When using carboxylate, sulfonate, sulfate, etc., the hydrophobic interaction with component (c) is too strong, and it is considered that there is a defect that the bactericidal action of component (c) is deactivated. (D) component used for this invention does not contain a long-chain alkyl group, As a result, since hydrophobic interaction is moderate, it is thought that the bactericidal action of (c) component can be maintained.

  In the liquid detergent composition for hard surface of the present invention, a surfactant other than the component (a) can be blended as the component (e). As the component (e), one or two of the compounds listed as “component (b)” in Japanese Patent Application Laid-Open No. 11-189796, which do not correspond to the component (a) of the present invention, are used. The above can be used. However, in the liquid detergent composition for hard surfaces of the present invention, the content of an anionic surfactant having 8 or more carbon atoms is 1% by mass or less, and further 0.5% by mass from the viewpoint of bactericidal efficacy and cleaning performance. The following is preferable. In addition, the total amount of (a) component and (e) component is 0.1-10 mass% in the liquid detergent composition for hard surfaces of this invention, Furthermore, 0.2-8 mass% is preferable. The total amount does not include the amount of component (c).
