Abstract

PROBLEM TO BE SOLVED: To provide a liquid detergent composition having excellent detergency without causing wiping irregularity in case of using for surface of glass, a mirror or the like as well as preventing fog by compounding a surfactant and a polyether modified silicone of a specific molecular weight. SOLUTION: A molecular weight of a polyether modified silicone to be used is 10,000-50,000. A compounding amount of a surfactant is usually 0.0001-5.0 wt.% on the basis of a total amount of a liquid detergent composition. Particularly, in case of improving a retention of a fog prevention effect, a user of polyoxyalky ether type nonionic surfactant represented by the formula (wherein R1 and R2 are each an alkyl or H, the both are not H at the same time, and further the sum of a carbon number of the both is 7-25; and n is an integer of 1-50) is preferable. A compounding amount of the polyether modified silicone is usually 0.005-10 wt.%. Further, detergency improves sharply by incorporating an alkanolamine into the composition.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition for glass, mirrors and the like, and more particularly to a liquid detergent composition which is excellent in cleanability when used on the surface of glass and mirrors and does not cause uneven wiping. And a liquid detergent composition capable of simultaneously preventing fogging.

[0002]

2. Description of the Related Art Conventionally, as a liquid detergent composition on the surface of glass or a mirror, for example, Japanese Patent Application Laid-Open No. 58-21495 of the applicant of the present invention has excellent detergency and easy wiping. Disclosed is a glass cleaner having less stain residue (wipe residue). The liquid detergent composition disclosed in this publication contains a polyoxyethylene type nonionic surfactant and a polyoxyethylene alkyl ether sulfate in a specific ratio, and further contains an organic solvent having a boiling point of 150 ° C. or lower. The composition.

[0003] On the other hand, with respect to measures for anti-fogging, generally, the phenomenon of fogging is a state where countless fine water droplets adhere to the surface of glass or the like and diffusely reflect light. It is believed that fogging can be prevented by taking measures to prevent the formation of hemispherical water droplets in the above. Conventionally, the following measures (1) to (4) have been adopted and implemented as measures for preventing fogging. (1) Measures to reduce the contact angle between the glass surface and the adhering water droplets, and to spread the water droplets to form a water film and prevent irregular reflection of light. (2) Measures to prevent water droplets from forming on the surface of glass by absorbing a water content by providing a specific adsorption layer on the surface. (3) A method that increases the contact angle between the surface of glass and other water droplets and repels the water droplets, causing the water droplets to fall off without stopping on the surface of glass and other surfaces. (4) Measures to keep water vapor from agglomerating, for example, by always keeping the surface of glass or the like at a temperature higher than the dew point.

Japanese Patent Application Laid-Open No. 4-180916 discloses an example in which the above-mentioned method (1) is used. An ether having at least one epoxy group having a molecular weight of 50 to 10,000 and an amino group and a hydrolyzate in one molecule are disclosed. An anti-fogging agent containing a silicone-modified ether having a specific structure obtained by reacting an organosilicon compound having at least one functional group with each other is disclosed. A glass cleaner having anti-fog property is disclosed in Japanese Patent Application Laid-Open No. Hei 9-151368.
Japanese Patent Application Laid-Open No. Hei 9-157635 discloses a transparent antifogging film comprising a hydroxyl group-containing polymer, an aluminum-containing crosslinking agent, and a surfactant containing a hydroxyl group, a siloxane group or a mixture of these groups. JP-A-9-194492 discloses an antifogging agent comprising an anionic surfactant and an organopolysiloxane having a hydrophilic group, and an organopolysiloxane having a specific molecular weight having at least one specific anionic group. Anti-fog agents are disclosed.

However, since the glass cleaners described in the above publications emphasize the function as a cleaning agent, many of them have no antifogging effect or have an insufficient antifogging effect.
