Liquid detergent composition

The present invention relates to a liquid detergent composition for dishwashing and human body, and more particularly, plant extracts containing saponin are formulated to maintain the original function of these extracts, as well as to enhance the foaming and cleaning power in use. It relates to a liquid detergent composition for kitchen and human body.

In general, the liquid detergent is composed of a surfactant, a detergent preparation, an active ingredient, a fragrance and water, etc. Among them, only the surfactant exerts the washing ability and the bubble power at the same time.

Surfactants commonly used in cleaning agents include alkylbenzenesulfonates, alphaolefin sulfates, sodium or ammonium lauryl sulfates, alkylbetaines, amine oxides, ethoxylated alcohol ethers, alkylpolyglucosides, and fatty acid amides. All are synthetic surfactants starting from one component of petroleum or plant. However, synthetic surfactants sometimes cause skin irritation and dermatitis such as housewife eczema and remain on the surface of the substance to be cleaned after washing, thereby providing a cause of human toxicity.

Therefore, efforts are being made to develop hypoallergenic surfactants or products using small amounts of surfactants as much as possible. In addition, in recent years, attempts have been made to add natural extracts, cucumber juice, apricot juice, lemon juice, aloe, etc. to liquid detergents to impart a fresh natural flavor and to provide the product with moisturizing and nourishing effects. have.

However, these plant extracts have a problem such that, in some cases, the inherent washing power and / or foaming power of the cleaning agent are reduced, thereby limiting the amount used.

Under these circumstances, the present inventors show a skin protection effect, a moisturizing effect, and impart a fresh plant odor of a plant extract when added to a liquid detergent without having the problems of the prior art described above, and unlike the conventional plant extracts, the cleaning power and air bubbles are different. Extensive research has been conducted to provide a liquid detergent containing a plant extract capable of increasing the use of synthetic surfactants to reduce the amount of synthetic surfactants. The purpose of this can be achieved by incorporating an extract of a plant containing saponin into the liquid detergent. To discover and complete the present invention.

That is, an object of the present invention is to provide a liquid detergent composition, characterized in that it contains an extract of a plant containing saponin in an amount of 0.5 to 20 parts by weight of the total weight of the composition.

Another object of the present invention is as an extract of a plant containing saponin, Asparagus, Butchers bloom, Calendula, Dead nettle, Ginseng, Horse chesetnut The total weight of the composition of the extract of one or two or more plants selected from the group consisting of Horsetail, Liquorice, Rosemary, Sage, Yucca and Quillala It is to provide a liquid detergent composition characterized by containing in an amount of 0.5 to 20 parts by weight.

Still another object of the present invention is an extract of a plant containing saponin, Asparagus, Butchers bloom, Calendula, Dead nettle, Ginseng, Horse chesetnut ), Horsetail, Liquorice, Rosemary, Rosemary, Sage, Yucca and Quilala, extracts of two or more plants from 0.5% of the total weight of the composition. It is to provide a liquid detergent composition characterized by containing in an amount of ˜20 parts by weight.

Still other objects and applications of the present invention will become apparent to those skilled in the art from the following detailed description.

According to the present invention there is provided a liquid detergent composition comprising a combination of plant extracts containing saponin.

Saponin is a generic term for vegetable surfactants contained in plants to create bubbles. Saponins in nature are composed of the following two structures: Aglycone and Glucose moiety.

Unsugared part of saponin

Extracts of plants containing saponins include Asparagus, Butchers bloom, Calendula, Dead nettle, Ginseng, Horse chesetnut, Horsetail ), Liquorice, Rosemary, Sage, Yucca, and Quilala, and the main components and effects of these plants are shown in Table 1 below. .

Conventional liquid detergent composition containing a plant extract is composed of 5.0 to 20.0% by weight of sulfonate, 0.5 to 10.0% by weight of a thickener such as fatty acid amide, amine oxide, etc., plant extracts of cucumber juice, lemon juice, aloe and the like. It contains 0.0 ~ 3.0 parts by weight to give skin moisturizing effect and natural odor when in contact with or use of human body. As described above, these compositions have limited use amount because they reduce the foaming force and the cleaning power of the cleaning composition, and thus, it is difficult to obtain a desired effect with a small amount of use.

However, when the saponin-based plant extract is contained in an amount of 0.5 to 20 parts by weight based on the total weight of the liquid detergent, as in the present invention, the plant extract itself has a moisturizing effect, natural odor function, as well as washing power and foaming power. It has the advantage of reducing the amount of synthetic surfactant formulated into the detergent or improving its performance. The plant extract according to the present invention can be obtained by a conventional method of treating each plant to obtain an extract from the plant. In particular, water is preferably used as the extraction solvent.

The difference in the human safety of natural and synthetic surfactants is due to the fact that synthetic surfactants must undergo excessive chemical reactions in their synthesis, whereby by-products or residual oxidation products or metal oxides are mainly toxic agents. Therefore, in order to increase human safety, it is necessary to reduce the content of the synthetic surfactant as much as possible. Since the saponin-based plant extract according to the present invention functions as a natural surfactant, it can function as a substitute for a synthetic surfactant in a known liquid detergent. It is one of the features of the present invention to be able to reduce the amount of synthetic surfactant used.

Hereinafter, the present invention will be described in detail with reference to Examples.

Example 1 and Comparative Examples 2-3

Note 1: POE means pleoxyethylene group.

Each of the above components was mixed in order at room temperature to prepare a dishwashing liquid detergent.

Among the above components, the plant extracts of (e), (f), (g) and (h) are crushed to each plant, warmed in a pressure vessel with an appropriate amount of water, compressed and filtered, and the filtrate is vacuum dried. It is the powdery extract obtained.

The foaming power, washing power, and usability of each composition were measured, and the smell was sensory evaluated. The results are shown in Table 2 below.

Note 1: The bubble force is the bubble height after rotating 100 ml of each 0.2% aqueous solution and 25 ml in a cylinder of diameter 3cm and height 30cm by 30 degreeC at the same rotation method.

Note 2: The washing power was calculated by the weight ratio of each 0.2% aqueous solution rotated for 5 minutes with a stirrer at room temperature after contaminating the oil stain made of edible oil on the microscope glass according to the Linz method (KSM 2716).

Note 3: Thirty patients were sensibly judged on the roughness of skin after dish washing in the kitchen, and the results were compared and evaluated based on the following criteria.
