Description

The present invention relates to a treatment agent composition for a hard surface and a method for improving the wettability of a hard surface.

Hydrophobic hard surfaces such as bathtubs often have vertical or inclined surfaces, but in order to remove stains on these parts, use a spray or the like to clean them containing anionic surfactants and amphoteric surfactants. It is effective to spread the agent.
However, there is a drawback that the effect of the cleaning agent is not sufficiently exhibited because the cleaning agent does not sufficiently stay on the vertical surface or the inclined surface of a hard surface such as a bathtub and drips in a streak shape.
On the other hand, there are various methods of increasing the adhesion retention of the cleaning agent by various thickening methods and lowering the contact angle to suppress the dripping of the cleaning agent on vertical and inclined surfaces and exert a cleaning effect. ..
Patent Document 1 discloses a polymer for increasing the viscosity and a method of using a nonionic surfactant or a solvent as a contact angle lowering agent.
Further, Patent Document 2 describes that a dishwashing detergent containing a short-chain alcohol can be sprayed.

Japanese Unexamined Patent Publication No. 2004-210808 Special Table 2018-536060

However, Patent Document 1 requires a thickener such as a polymer, so that it is uneconomical and cannot be sprayed by spraying. Therefore, it can be sprayed and efficiently applied to the entire surface of a hydrophobic hard surface without running out of liquid. A treatment agent that can be spread is required.
Further, Patent Document 2 does not suggest that when the surfactant and the short chain alcohol are in a specific ratio, the wettability and spreadability when applied to a vertical plane can be improved.

INDUSTRIAL APPLICABILITY The present invention uses a treatment agent composition for a hard surface, which improves adhesion and wettability when sprayed onto a hard surface, and has good ejection properties and compounding stability by spraying. Provided is a method for improving the wettability of a hard surface.

The present invention comprises (a) a compound having a hydrocarbon group having 6 or more and 12 or less carbon atoms and having an HLB of 2.5 or more and 9 or less determined by the Griffin method [hereinafter referred to as (a) component], (b) an interface. Activator (excluding component (a)) [hereinafter referred to as component (b)] is 0.1% by mass or more and 10% by mass or less, (c) water-soluble organic solvent [hereinafter referred to as component (c)],. And water, and the mass ratio (a) / (b) of the content of the component (a) to the content of the component (b) is 0.05 or more and 0.43 or less, and the content of the component (a) is contained. A composition of a hard surface treatment agent having a mass ratio (a) / (c) of the amount to the content of the component (c) of 0.1 or more and 1.4 or less and a viscosity at 20 ° C. of less than 50 mPa · s. Regarding things.

The present invention relates to a method for improving the wettability of a hard surface by bringing the hard surface treatment agent composition into contact with the hard surface.

The present invention relates to an agent for improving the adhesion and wettability of a surfactant-containing composition to a hard surface, which comprises the component (a).

According to the present invention, a treatment agent composition for a hard surface, which improves the adhesiveness and wettability and spreadability when sprayed onto a hard surface, and has good ejection properties and compounding stability by spraying, and the like. A method for improving the wettability of a hard surface using the above method is provided.
Since the treatment agent composition for a hard surface of the present invention exhibits high wettability even on a hydrophobic hard surface, for example, it has high adhesion even when sprayed onto a vertical surface of a hydrophobic hard surface. In addition, the wettability and spreadability prevent the liquid from running out, and the residual amount of the agent is improved. As a result, it also leads to improvement of detergency.

[Hard surface treatment agent composition]
It is not always clear why the composition for treating a hard surface of the present invention is sprayed onto a hard surface and has improved adhesiveness and wettability, and has good ejection properties and compounding stability by spraying. It is estimated as follows.
The component (a) of the present application having a hydrocarbon group having a specific carbon number and a specific HLB has higher molecular motility than the component (b) of the present invention, and has a higher affinity with a hydrophobic surface than the component (b). Due to its excellent properties, when the hard surface comes into contact with the treatment agent composition, the component (a) is rapidly adsorbed on the interface, and the hydrophobic surface is formed with a surface compatible with the component (b). As a result, the hard surface treatment agent of the present invention can be wetted and spread on the hard surface, and the residual property of the treatment agent can be improved. The effect can be achieved by using the component (b) and the component (a), and the component (c) and the component (a) in a specific ratio, even if the viscosity is low enough to be spray-discharged. The treatment agent can be wetted and spread on a hydrophobic hard surface to leave the treatment agent. Further, it is presumed that the compounding stability of the treatment agent could be improved.
Further, the component (a) of the present invention is a hydrophobic compound and is very difficult to dissolve in water. In order to stably dissolve this compound in the composition, it can be achieved by using a surfactant as a component (b) and a water-soluble solvent as a component (c) in combination. However, the effect of the present invention cannot be achieved only by blending the component (c), stable blending cannot be achieved if the component (b) and (c) are insufficient, and the effect of the component (a) is obtained if the amount is too large. Is impaired. Therefore, the effect of the present invention can be achieved by setting the mass ratio of the component (a) to the component (b) and the component (c) within a specific range.
