Description

Skin cleanser composition

The present invention relates to a skin cleanser composition.

Conventionally, a skin cleanser composition has been preferred to have a refreshing feel and elastic foam quality after washing, and contains a higher fatty acid salt and an amphoteric surfactant or alkylamine oxide as a cleaning base material. There has been proposed a detergent composition for fingers which is excellent in improvement of detergency and has excellent detergency against oily and odorous stains, and does not easily leave a fragrance in the hand (for example, see Patent Document 1).

However, this proposal does not provide sufficient deodorizing power and sustainability of deodorizing power, even though it improves cleaning power, because the deodorizing power against odor stains from fish and meat depends on masking with fragrances. Furthermore, there are problems that the elasticity of the foam, the persistence of the foam, and the moist feeling of the skin after washing are insufficient.

Therefore, it is desired to provide a skin cleanser composition that has good detergency, foam elasticity, and foam persistence, and is excellent in deodorant power, deodorant power persistence, and moist feeling after washing. It is rare.

As the squeeze foamer container and the pump former container, for example, those manufactured by Daiwa Steel Co., Ltd., Yoshino Kogyo Co., Ltd., etc. can be used.

As a material of the porous membrane, for example, a plastic material such as nylon, polyester, or polyolefin is preferable. The mesh of the porous membrane is not particularly limited and may be appropriately selected depending on the intended purpose. For example, 100 mesh or more is preferable, 100 mesh to 400 mesh is more preferable, and 200 mesh to 350 mesh is preferable. Particularly preferred. If the mesh of the porous membrane is less than 100 mesh, the elasticity of the foam and the persistence of the foam may be insufficient.
The number of the porous membranes is preferably 2 to 4 from the viewpoint of the elasticity of the bubbles and the durability of the bubbles. When the number is less than 2 or more than 4, the feeling of elasticity of the foam and the persistence of the foam may be insufficient. More specifically, the former containers described in JP-A-7-315463, JP-A-8-230961, and JP-A-2005-193972 can be preferably used.

(Examples 1 to 47 and Comparative Examples 1 to 10)
Skin cleansing compositions having the compositions and contents shown in Tables 1 to 9 below were prepared by the following method. That is, the component (A) and the component (C) were dissolved in purified water, which is a common component, and then the component (B) was dissolved. Thereafter, if necessary, the component (D) and the common component were added and dissolved uniformly to prepare a skin cleansing composition.
The pH of the prepared skin cleanser compositions of Examples 1 to 47 and Comparative Examples 1 to 10 was adjusted to 10.2 with citric acid and potassium hydroxide. The pH was measured at 25 ° C. using a pH meter (trade name: “HM-30V”, manufactured by Toa DKK Corporation).
Next, the skin cleansing compositions of Examples 1 to 47 and Comparative Examples 1 to 10 were mixed with a pump dispenser container (trade name: P1-1, manufactured by Canyon Co., Ltd., discharge amount: 1 mL, nozzle diameter: diameter 3. 6 mm) was filled with 40 mL.

For the skin cleansing compositions (hand soaps) filled in the prepared pump dispenser containers of Examples 1 to 47 and Comparative Examples 1 to 10, “deodorizing power”, “deodorizing power” “Sustainability”, “detergency”, “feel of elasticity of foam”, “sustainability of foam”, and “moist feeling of skin after washing” were evaluated. The results are shown in Tables 1 to 9.

Ten professional panelists stretched 1g of raw horse mackerel over the fingers of both hands, wet both hands with water, rub each hand with 1g of the skin cleansing composition for 20 seconds, and then rubbed the hands for about 10 seconds in running water. After rinsing and towel drying, an average evaluation score was determined according to the following criteria. Next, “deodorizing power” against fish odor was evaluated according to the following evaluation standards for deodorizing power. Thereafter, 3 hours later, in the same manner as the evaluation of the “deodorizing power”, the smell of fish remaining in the hand was sniffed, and an average evaluation score was obtained according to the following criteria. Next, in accordance with the following evaluation criteria for the deodorant power sustainability, the “deodorant power sustainability” for fish odor was evaluated.
