Description

[0001] GEL TYPE DETERGENT COMPOSITION [0002]

The present invention relates to a gel detergent composition.

Detergent is a generic term for organic and inorganic compounds used for cleaning the body in everyday life and for cleaning other things such as textile, tableware, food, metal, oil, dust, soot, etc. There are many.

In the case of these detergents, liquid detergent and powder detergent are predominant, and powder detergent is easy to mass-produce, but has a disadvantage in that it is bulky compared with the weight, so there is a problem that a lot of product storage, transportation cost and facility cost must be invested . Also, in the case of liquid detergent, the detergent flows down when the detergent is applied to a corner or a vertical surface due to a low viscosity, and the detergency is reduced, and a large amount of detergent must be continuously sprayed on the contaminated surface. Particularly in the corner or folded portion, the contamination of the detergent is difficult to penetrate deeply, and the viscosity of the detergent is so low that the coating thickness of the detergent is so small that it is difficult to clean the contaminant.

In order to solve such problems, a gel type detergent capable of dissolving stubborn contaminants while maintaining a high cleaning power at the time of applying a certain amount to a wall surface, a bent surface, a corner surface, have.

Examples of the method for producing such a gel detergent include a step of mixing components such as a detergent composition and a gelling agent, a step of stirring the mixture while heating to obtain a gel product, and a step of pouring the gel product into a molding die to solidify Is known.

For example, in Patent Document 1, a mold is used as a mold for molding in a gel-like semi-solid cleaning composition in which an anionic surfactant and a positive surfactant are mixed with a natural gelling agent. However, since the gel-like cleaning agent has a high water content and the gelling agent is liable to be spoiled, microorganisms such as bacteria tend to propagate and time is required for washing the mold to be reused. In addition, since a molding frame must be prepared for each desired size of the gel-like cleaning material, the production of the gel-like cleaning material was inefficient.

Patent Document 2 discloses that a cylindrical body is used as a molding frame in a gel-like cleaning material in which a cleaning component and a polysaccharide are blended, but it is not disclosed in which material the container is formed.

Therefore, the inventors of the present invention have made efforts to produce a gel-type detergent having a high viscosity without requiring a molding frame while having a high viscosity as described above, and then, using the D-limonene oil as an environment- The composition was prepared and the present invention was completed.

FIG. 2 shows FT-IR analysis results of a detergent composition and washing water in an embodiment of the present invention.

Hereinafter, the present invention will be described in detail.

The present invention relates to a gel-type detergent composition using D-limonene and a surfactant. More specifically, the present invention relates to a gel detergent composition comprising D-limonene oil 100 parts by weight and ethylene oxide-added surfactant 80 To 120 parts by weight of water and 80 to 120 parts by weight of water, and has a viscosity of at least 10,000 cps.

In the present invention, the D-limonene oil is a natural oil component extracted from orange peel, which is environmentally friendly and stable solvent, has high dissolving power against organic pollutants, is excellent in biodegradability, and is environmentally friendly.

In the gel-type detergent composition of the present invention, a gel-type detergent composition having a high viscosity can be prepared by mixing the D-limonene oil and a surfactant to prepare a mixture, then adding water and further mixing.

At this time, the surfactant may be a nonionic surfactant represented by the following formula (1) as an ethylene oxide addition surfactant:

[Chemical Formula 1]

R1-O- (EO) x- (PO) y-H

Wherein EO represents an oxyethylene group, PO represents an oxypropylene group, and x represents an average addition mole number of ethylene oxide, wherein R < 1 > represents an alkylene group having 1 to 10 carbon atoms, To 10, and y is an average addition mole number of propylene oxide of 1 to 5.)

Hydrophile-Lipophile-Balance (HLB) property of the nonionic surfactant can be determined according to the ratio between the ethylene oxide repeating unit and the propylene oxide repeating unit contained in the surfactant. That is, the HLB value is a numerical value of the degree of hydrophilicity and lipophilicity of the surfactant. The smaller the HLB value is, the stronger the lipophilic property is, and the larger the HLB value is, the stronger the hydrophilic property is. That is, the HLB value is one of the indexes showing the characteristics of the surfactant, and represents the relative difference between the hydrophilicity and the lipophilicity of the surfactant.

Therefore, the nonionic surfactant contained in the detergent composition of the present invention includes a hydrophobic part and a hydrophilic part, and the hydrophobic part of the nonionic surfactant binds to hydrophobic D-limonene oil, and the hydrophilic part binds with water So that it can be controlled to have a high viscosity such that a gel phase can be formed while having hydrophilicity and lipophilicity simultaneously. In the present invention, the surfactant preferably has an HLB value (hydrophilic-lipophilic balance) of 10-15 indicating affinity of the organic phase with the aqueous phase. In the range above or below the above range, the separation of the oil phase D-limonene from the water-in-water occurs, and it is difficult to produce a uniform gel.

As described above, hydrophilicity increases when the molar ratio of the ethylene oxide repeating units in the surfactant increases, and hydrophobicity increases when the molar ratio decreases. Therefore, the ratio of the ethylene oxide repeating units to the propylene oxide repeating units . In the present invention, the molar ratio of the ethylene oxide moiety is preferably 5 to 10. If it is less than or more than the above range, hydrophobicity or hydrophilicity becomes high, and it is difficult to realize a viscosity to form a gel phase.

In the present invention, the detergent composition further comprises 1 to 2 parts by weight of glycerin, 1 to 2 parts by weight of coconut oil, 0.1 to 1 part by weight of essential oil and 1 to 2 parts by weight of defoamer based on 100 parts by weight of the detergent composition .

The glycerin and coconut oil are added as a silver moisturizing agent. Glycerin is a material conventionally used for moisture retention and viscosity, and it contains 1 to 2 parts by weight based on 100 parts by weight of the detergent composition of the present invention. When it is used below the above range, the moisturizing function and the viscosity improving function can not be sufficiently exhibited, and when it exceeds the above range, it may not be economically advantageous and may cause deterioration of other properties.

The essential oil is added as a fragrance, and it contains 0.1 to 1 part by weight based on 100 parts by weight of the detergent composition of the present invention. If it is used below the above range, it can not sufficiently show the directionality, and if it exceeds the above range, it does not show an economic advantage and may cause a decrease in other properties.

The detergent composition of the present invention may further contain an antifoaming agent, preferably ethyl alcohol, and contains 1 to 2 parts by weight based on 100 parts by weight of the detergent composition of the present invention. In the case where the amount is used below the above range, the effect is insignificant, and when it exceeds the above range, the occurrence of bubbles increases, which is not preferable.

In addition, the detergent composition of the present invention may contain various substances other than the above-mentioned additive materials in order to impart functions such as detergent fragrance and deodorant.

Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited by the following examples.
