Description

The present invention relates to a skin cleansing composition, and more specifically, to a skin cleansing composition that has good foaming and foam quality (creamyness), is non-irritating to the skin, does not cause a squeaky feeling when rinsing, has an excellent moisturizing effect that gives a moist feeling after towel drying, and is also stable over time.

It has been known to use fatty acid alkali metal salts in skin cleansing compositions, and they are widely used due to their foaming and foam quality (creaminess) and lack of stickiness during rinsing. Fatty acid alkali metal salts generally refer to sodium salts, but they are not suitable for use in liquid cleansing agents due to issues such as water solubility, and potassium salts of fatty acids (potassium soaps) are used when making liquid cleansing agents. In other words, it is common to make liquid cleansing agents with potassium soaps with low Kraft points, such as potassium laurate and potassium oleate, as the main component (see, for example, Patent Documents 1 to 6).

However, the liquid detergent compositions based on potassium salts, mainly potassium laurate or potassium oleate, disclosed in Patent Documents 1 to 6, have good low-temperature stability, but generally only produce coarse foam and have the drawback of leaving the skin feeling dry and not moist after washing. Possible methods to obtain fine foam include changing the fatty acid composition of the potassium soap to one that contains more fatty acids with higher melting points than lauric acid or oleic acid, or adding fatty acids (unneutralized soap), but all of these methods have problems such as crystallization or gelation at low temperatures.

On the other hand, it is known that certain polymers are blended to reduce the squeaky feeling during rinsing and to improve foam quality (creaminess) (see, for example, Patent Documents 7 and 8).

However, the cleaning agents disclosed in Patent Documents 7 and 8 have the problem of odor deterioration over time.

In addition, it is known to add silicones, hydrocarbons, vegetable oils, animal oils, and other liquid oils to give a moist feeling after towel drying (see, for example, Patent Documents 9 to 11).

However, the cleaning agents disclosed in Patent Documents 9 to 11 have drawbacks such as reduced foaming and sticky feeling during rinsing.

The skin cleansing composition of the present invention is described in detail below.

[Cleaning agent]
The skin cleansing agent of the present invention can be used, for example, in body soap, facial cleansing foam, hand soap, and the like.

The formulation of the skin cleanser can be selected from known formulations according to the intended use and intended purpose. For example, it can be in the form of a liquid, cream, gel, paste, etc.

<Component (A)>
The component (A) used in the skin cleansing composition of the present invention is a salt of a higher fatty acid having 14 to 22 carbon atoms. This component is added as a component that contributes to foaming and foam quality (creaminess).

Examples of component (A) include higher fatty acids having 14 to 22 carbon atoms, such as myristic acid, palmitic acid, stearic acid, oleic acid, and behenic acid; vegetable oils and fats, such as olive oil and cottonseed oil; and animal oils and fats, such as fish oil and beef tallow. These can be used alone or in appropriate combinations of two or more.

In the present invention, from the viewpoint of cleaning power and foaming power, it is preferable to use higher fatty acids having 14 to 18 carbon atoms, and myristic acid, palmitic acid, and stearic acid are more preferably used. Although fatty acids having 12 or fewer carbon atoms have good low-temperature stability, they generally only produce coarse foam and may be irritating to the skin.

Examples of salts of component (A) include alkali metal salts and organic amine salts obtained by saponifying or neutralizing higher fatty acids with an alkali agent. Examples of alkali agents that can be used include inorganic alkalis such as sodium hydroxide, potassium hydroxide, sodium carbonate, and potassium carbonate, and organic alkalis such as monoethanolamine, diethanolamine, triethanolamine, trimethylamine, and triethylamine.

The blending amount of component (B) is preferably 0.01 to 2%, and more preferably 0.05 to 1%. If the blending amount is 0.01% or more, the foaming and foam quality (creamyness) are good, and the squeaky feeling during rinsing and the moist feeling after towel drying are improved. On the other hand, if the blending amount is 2% or less, the high temperature stability is good.

<Component (C)>
The component (C) used in the skin cleansing composition of the present invention is an N-acyl glutamic acid ester.
