Description

Glass cleaner composition with anti-fog

1 shows one application embodiment of the glass cleaner composition according to the invention.

The present invention relates to a glass cleaner composition having anti-fog together with glass cleaning. More specifically, the present invention relates to a glass cleaner composition having an excellent biodegradability and anti-fog function as well as a cleaning effect by containing an anionic surfactant, a fatty acid-based nonionic surfactant, a leveling regulator and a binder.

Conventionally, a glass cleaner composition composed of a strong odor, a glass solvent, an alkali agent and a small amount of surfactants is used to remove dirt, stains, etc. adhered to the glass surface (Japanese detergent, cleaning dictionary p 520-528). The cleaning effect of glass can be expected to be satisfactory, but due to the strong solvent odor generated when used as a strong solvent for strong cleaning, extremely harmful and low biodegradable surfactants are applied. Holding it. In addition, the anti-fog effect formed by the temperature difference between the inside and the outside of the glass in winter or rainy season is weak, which makes it difficult to secure the clock after glass cleaning.

Accordingly, the present invention provides a glass cleaner composition combining a hypoallergenic solvent with a biodegradable surfactant, a nonionic surfactant for preventing frost, and a leveling agent in an appropriate ratio in order to alleviate these disadvantages. It is done.

In general, when pollutants adhere to the glass surface, nitrogen oxides (NOx), sulfur oxides (SOx), and other inorganic compounds remaining in the air are attached by rain and organic matter such as hydrocarbons and ketones generated by exhaust gas. It can be divided into compounds, and firstly, soot and oil residues are also present. In order to remove the pollutants of these organic and inorganic compounds, it is necessary to combine the primary method of physical removal and the secondary method of chemical removal. In the secondary removal method, the inorganic compound contamination can be removed by constructing a strong aromatic solvent such as ammonia water and a compound having excellent metal binding power. A compound having excellent solvent and metal binding strength was used. However, in the present invention, a compound having excellent metal binding power was used, excluding human irritation due to strong odor during manufacture or use.

In addition, the organic compound contamination has a large effect on the environmental pollution as well as the human body by using a low biodegradable surfactant in the prior art, in the present invention by using a mixture of anionic surfactant and non-ionic surfactant with excellent biodegradability Synergy effect to improve the cleaning properties to have a strong solvent function.

In addition, in the prior art, only the basic function of cleaning, the use of solvents and surfactants having a strong odor against the frost of winter or rainy season caused by the temperature difference in the glass appeared temporary temporary anti-fog effect, in the present invention, glass basic cleaning function In addition, in order to reinforce the weak anti-fog effect, anionic and nonionic surfactants are mixed and a thin film is formed on the glass surface using a fluorine-based special surface control agent so that the thin film is not easily broken.

The occurrence of frost on the glass surface and decontamination are described in detail as follows. Due to the temperature difference between the inside and outside of the glass, the high temperature glass surface instantly condenses vapor in the air due to the relative temperature difference and adheres to the glass surface in the liquid state. It is arranged on the surface, and this phenomenon is said to be caused by fog.

In order to prevent this phenomenon, the static electricity that causes the repelling force of fine water droplets is canceled so that it spreads through the water thin film on the glass surface, and it maintains the thin film and controls the surface to prevent diffuse reflection while securing a clear field of view. . When such a thin film is formed and the surface is controlled, surfactants are unevenly arranged on the glass surface as shown in FIG. 1, and the surface control agent and the thin film retaining component are surrounded thereon to maintain the anti-fog function.

Specifically, the glass cleaner composition according to the present invention comprises 0.5 to 5 parts by weight of a mixture of a fatty alcohol-based anionic surfactant and a fatty acid-based amide-substituted nonionic surfactant, 0.01 to 5 parts by weight of a surface control agent, 0.5 to 10 parts by weight of a binder and It is characterized by containing a hypoallergenic solubilizer.

In the composition of the present invention, binders are used to remove inorganic odors such as ammonia water to remove inorganic contamination, and a compound having excellent binding power is used. Preferably, Na-EDTA (ethylenediamine tetraacetic acid) or nitrilotriacetic acid is used. Used.

EDTA is particularly preferably a compound in which 2 to 4 Na are added. The amount of the binder used is preferably 0.5 to 10 parts by weight. If the amount is less than 0.5 parts by weight, the binder effect is weak, and if it is used more than 10 parts by weight, the skin irritation becomes strong. In addition, the binding force is excellent, there are phosphate system and citric acid, but phosphate may cause environmental pollution, and citric acid has a weak binding force.

The composition of the present invention provides a synergy effect by using a mixture of fatty alcohol-based anionic surfactant and fatty acid-based amide-substituted nonionic surfactant having excellent biodegradability to remove organic pollution. The anionic surfactant has 12 to 14 carbon atoms, preferably 2 to 10 ethylene oxide is added and sulfated. In addition, the nonionic surfactant preferably has 12 to 18 carbon atoms and 1 to 2 amide groups are added.

The composition of the present invention may contain 0.5 to 5 parts by weight of a mixture of fatty alcohol anionic surfactant and fatty acid amide-substituted nonionic surfactant. When less than 0.5 parts by weight is used, the cleaning power is weak, when using more than 5 parts by weight there is a problem that additional bubble removal process is necessary due to excessive foaming.

In the composition of the present invention, the thin film formation of the anionic surfactant used for organic decontamination, and the nonionic surfactant and the surface control agent used for the purpose of preventing the anti-reflective effect to maintain it exhibit an anti-fog effect. The surface modifier is preferably a fluorine-based surfactant, the amount of which is preferably 0.01 to 5 parts by weight. When using less than 0.01 weight part, the effect is insignificant, and when using 5 weight part or more, wiping property falls.

The composition of the present invention may also contain low cost ethanol, preferably as a hypoallergenic solubilizer. This solubilizer is preferably used in an amount of 20 to 40 parts by weight.

In addition, the composition of the present invention may contain trace amounts of fragrances, dyes, water and the like as other auxiliary components.

Hereinafter, the present invention will be described in more detail.
