Description

Hand dishwashing detergent composition

The present invention relates to a hand dishwashing detergent composition.

The industry is strongly seeking cleansing power for hand-washing dishwashing detergents. Many users use hand-washing dishwashing detergents to clean tableware or cooking utensils. After cleaning the tableware with hydrophilic surface such as glass or ceramic utensils with less oil stain or slipping, the final cleaning oil is more or less slippery. A tableware with a hydrophobic surface such as a Tupper or a lunch box. Further, the tableware or the cooking utensil is immersed in a dishwashing water bath, and the hot water of about 40 ° C to 45 ° C is used or washed twice. The main reason for adopting these methods is the adhesion of oil stains to the surface of utensils or cooking utensils, especially liquid oils such as rapeseed oil, and solid fats contained in butter or lard, which are stubbornly attached to the storage box or A tableware or cooking utensil having a hydrophobic surface such as a lunch box. Therefore, many users consider that it is desirable to remove oil stains that are stubbornly attached to dishes or cooking utensils having a hydrophobic surface at relatively low temperatures (10 to 35 ° C), that is, dirt containing liquid oil and solid oil. .

<cleaning force test>

A polypropylene dish (C-39 PP platter made by Kanto Plastic Industry Co., Ltd.) was coated and spread into a rapeseed oil (Kishida Chemical Co., Ltd.) and uniformly mixed with 0.1% by mass of a pigment (Sudan III, Model Chemicals of Tokyo Chemical Industry Co., Ltd.) 1 ml of polypropylene dish is set as a model contaminated tableware (1). In addition, the mixture was prepared by uniformly spreading the directional butter (Sigma-Aldrich Japan Co., Ltd.) or the mixture of rapeseed oil and tallow at a mass ratio of 1:1 to 0.1% by mass. The model oil of 1 g of the above-mentioned pigment was set as a model-contaminated tableware (2) and (3), respectively.

1.0 g of the hand dishwashing detergent composition of Tables 1 to 2 and 30 g of tap water of 25 ° C were infiltrated into a sponge (trade name: KIKULON A, KIKULON Co., Ltd.), and the hand was rubbed 2 to 3 times to make it Foaming. The model is used to scrub the model-contaminated tableware, and the time at which the coloring caused by the coloring is no longer visible or the time when the coloring film cannot be removed is set as the end point. Thereafter, the model-contaminated tableware was washed with a stream of tap water, and the presence or absence of the slipping feeling caused by the oil stain remaining in the tableware was confirmed by hand, whereby the number of pieces of the dish having no slippery feeling was evaluated as the number of clean sheets. Contaminated tableware for each model (1)~(3), the test was carried out one by one. Here, for the model-contaminated tableware (1) (rapeseed oil), it is acceptable to continuously clean six or more pieces, and for the model-contaminated tableware (2) (tallow), one piece or more can be continuously cleaned. In the case of the model-contaminated tableware (3) (canola oil/tallow), it is acceptable to clean one or more pieces.
