Description

  The present invention relates to a dishwashing composition for hand washing.

  There is a strong demand for dishwashing agents for hand washing that have a strong detergency against oil stains. Many users use a dishwashing agent for hand washing to wash dishes and cooking utensils, washing dishes with a hydrophilic surface, such as glass or pottery dishes that are less oily or easy to remove, and then use oil. It is designed to wash dishes with a hydrophobic surface such as plastic tappers and lunch boxes that are dirty or difficult to remove. In addition, it has been devised to immerse tableware and cooking utensils in a dish water detergent bath, use hot water of about 40 ° C. to 45 ° C., or wash twice. These contrivances are that oil stains adhere to the surface of dishes and cooking utensils, especially liquid oils such as rapeseed oil, and solid fats such as beef tallow and pork tallow have hydrophobic surfaces such as tappers and lunch boxes. The main cause is the strong adhesion to tableware and cooking utensils. Therefore, many users remove stains containing liquid oil and solid oil, which are oil stains strongly adhered to dishes and cooking utensils having a hydrophobic surface at a relatively low temperature (10 to 35 ° C.). I want to.

  Patent Document 1 discloses a liquid detergent containing dialkyl sulfosuccinates and amine oxides, which improves low-temperature detergency against oil and / or starch soils. Patent Document 2 discloses a technique of a cleaning agent suitable for dishwashing, which contains a sulfosuccinic acid diester type surfactant and a foaming booster, has high foaming properties and excellent detergency. Patent Document 3 discloses a liquid or gel detergent composition in which a sulfosuccinic acid dialkyl ester salt can be used as an anionic surfactant, and further describes that it can contain betaine and / or an amine oxide. . Patent Document 4 describes a low-irritant cleansing composition that contains a sulfosuccinic acid monoester salt and provides an excellent moisturizing and conditioning effect on the hair and skin.

<Detergency test>
Polypropylene dish (Kanto Plastic Industry Co., Ltd., C-39 PP meat dish) and rapeseed oil (Kishida Chemical Co., Ltd.) and 0.1% by weight pigment (Sudan III, Tokyo Chemical Industry Co., Ltd.) are mixed uniformly. Polypropylene dishes coated with 1 ml of model oil stains were used as model contaminated dishes (1). Similarly, a model oil stain in which 0.1% by mass of the pigment is uniformly mixed with beef tallow (Sigma Aldrich Japan Co., Ltd.) or a mixture of rapeseed oil and beef tallow at a mass ratio of 1: 1. Polypropylene dishes coated with 1 g were used as model contaminated dishes (2) and (3), respectively.

  Dip a dish (trade name: Kikuron A, Kikuron Co., Ltd.) with 1.0 g of the dishwashing detergent composition for hand washing shown in Tables 1 and 2 and 30 g of tap water at 25 ° C. Bubbled. Using this sponge, the model-contaminated tableware was scrubbed, and the end point was the point at which coloring by the pigment was not observed or the pigment could not be removed. Thereafter, the model-contaminated tableware was rinsed with running tap water, and the presence or absence of null-sticking due to oil stains remaining on the tableware was checked by hand, and the number of dishes without null-sticking was evaluated as the number of washings. This test was individually performed for each of the model contaminated dishes (1) to (3). Here, 6 or more for model contaminated tableware (1) (rapeseed oil), 1 or more for model contaminated tableware (2) (beef tallow), and for model contaminated tableware (3) (rapeseed oil / tallow) In this case, one or more sheets can be successively washed.
