Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass cleaner composition,
More specifically, the present invention relates to a glass cleaner composition that has high detergency, is easy to wipe off, and leaves no residue after wiping.

Glass cleaners lift contaminants such as sand, dust, other inorganic substances, and organic substances such as hand grime, oil, and fatty acids from the glass surface, dissolve or disperse them, and then wipe them off with a cloth or paper. Various glass cleaners have been proposed and commercially available.

However, conventionally proposed or commercially available glass cleaners are still unsatisfactory in terms of basic performance such as cleaning power and wiping performance, and there is still much room for improvement. That is, it cannot sufficiently remove stubborn stains involving organic matter, and it also has drawbacks such as wiping streaks remaining due to contaminants or glass cleaner residue after wiping. Although various developments have been made regarding glass cleaners in order to eliminate these drawbacks, there is still no perfect product. As a result of intensive research to improve the drawbacks of these glass cleaners, the present inventors discovered that a glass cleaner containing a specific surfactant significantly improved the cleaning power and wiping performance, and completed the present invention. did.

That is, the present invention contains as essential components (2) a nonionic surfactant, (uniform long chain N-acylamino acid or a salt thereof, and (
The present invention provides a glass cleaner composition characterized by containing a cloud ionic surfactant.

Traditionally, the cleaning ingredients of glass cleaners are surfactants,
It is known that a composition containing an alkaline agent and a solvent is most effective, but according to the present invention, in a glass cleaner composition containing a surfactant, an alkaline agent, and a solvent as cleaning ingredients, It has been found that when a long-chain N-acyl amino acid or a salt thereof is combined with an anionic surfactant or a nonionic surfactant as an agent, extremely remarkable cleaning power is exhibited.

Increasing the cleaning power also lifts contaminants from the glass surface and disperses the contaminants, which also improves wiping performance. Furthermore, it is conceivable to increase the amount of surfactant to improve detergency, but in that case, stubborn bubbles will form, and even after wiping, the bubbles will remain as wiping streaks, impairing the finish. However, when the surfactant system of the present invention is used, the cleaning power is strong even without increasing the amount of surfactant, so this problem does not occur. In addition, when the surfactant system of the present invention is used, the cleaning liquid has good absorption properties to the cloth, probably because it wets the glue fibers better, and there is less re-adhesion of contaminants to the glass surface. Due to these effects, when the glass cleaner composition of the present invention is used, the contaminants can be completely removed even from glass surfaces covered with stubborn stains, and since the wiping property is good, there is no need to wipe twice. Can be finished with a clean glass surface.

(4) The nonionic surfactant used in the present invention is a higher alcohol having 8 to 22 carbon atoms and 1 ethylene oxide.
Examples include polyoxyethylene alkyl ether to which 1 to 150 moles of ethylene oxide have been added, and polyoxyethylene alkyl phenol ether to which 1 to 100 moles of ethylene oxide has been added to an alkylphenol whose alkyl group has 6 to 16 carbon atoms. A polyoxyethylene alkyl ether prepared by adding 1 to 50 moles of ethylene oxide to a higher alcohol of 1 to 20 is preferred.

Particularly preferred are polyoxyethylene alkyl ether sulfates in which the alkyl group has 10 to 20 carbon atoms and the number of moles of ethylene oxide added is in the range of 1 to 10. Examples of the salt include salts of alkali metals, ammonia, monoethanolamine, diethanolamine, triethanolamine, and the like.
