Description

Cleaning fee

The present invention relates to a cleansing agent suitable for washing a face. More specifically, the present invention relates to a cleaning agent capable of not only exhibiting sufficient detergency but also generating dense foam having an excellent texture and achieving an excellent feeling of use.

The cleaning agent used for face washing etc. generally contains a higher fatty acid soap from the viewpoint of detergency and foaming property. In particular, for facial cleansers, it has been considered to combine surfactants, fragrances, viscosity modifiers, moisturizers and other additives in order to improve the feeling of use and moisturizing properties in addition to detergency. There is.

In the cleaning agent, the foaming property largely depends on the type and amount of the higher fatty acid soap, but the higher fatty acid soap alone may not have sufficient characteristics in terms of the texture of the foam and the feeling of use after cleaning. That is, in the face-wash cleaning agent, when the higher fatty acid soap is used alone, the density of air bubbles does not easily increase when the cleaning agent is whipped, and it is difficult to reach a level at which the feeling of use after cleaning is satisfactory. Therefore, it has been studied to combine a viscosity modifier to adjust the texture of foam and to combine various additives to improve the feeling of use.

For example, a solid detergent composition in which a polyacrylic acid-based thickener and a specific polymer are combined with a higher fatty acid soap has been proposed (Patent Document 1). It is also being considered to combine sugars with body soap. However, especially in the cleaning agent for the purpose of face washing, the feeling of use after washing is emphasized, and further improvement is required as compared with the conventional cleaning composition.

(B) High fructose corn syrup,
It contains (c) a polymer having a cationic group and (d) water as essential components.

[(A) Higher fatty acid or salt thereof]
The higher fatty acid or a salt thereof that can be used in the present invention is not particularly limited as long as it is a neutralized product of a higher fatty acid generally used as a cleaning material, or a higher fatty acid ester or a saponified product of a fat or oil. What is generally called a higher fatty acid soap is a mixture of a higher fatty acid and a salt thereof, and can also be used as the higher fatty acid or a salt thereof (a) in the present invention.

As the higher fatty acid, a fatty acid having 8 to 22 carbon atoms is preferable, and it may be either linear or branched chain, and may be saturated or unsaturated. Specifically, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, palmitooleic acid, oleic acid, isomyristic acid, isoparmitic acid, isostearic acid, undecylenic acid, toll acid, linoleic acid, linoleic acid. , Eikosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) can be used as fatty acids selected from the group.

It is preferable to use a combination of seeds or more.

Examples of the alkali constituting the salt of the higher fatty acid include inorganic alkalis such as potassium hydroxide and sodium hydroxide, organic alkalis such as triethanolamine, and basic amino acids such as lysine and arginine. Of these alkalis, potassium hydroxide is preferred.

There is. The higher fatty acid soap that can be used in the present invention also preferably has a neutralization rate of 60 to 90 mol%. Therefore, in the present invention, the higher fatty acid or the salt (a) thereof preferably contains 60 to 90 mol% of the higher fatty acid alkaline salt and 10 to 40 mol% of the higher fatty acid. In particular, the higher fatty acid or its salt (a) more preferably contains about 80% of a higher fatty acid alkaline salt. The higher fatty acid or the salt (a) thereof does not have to be a neutralized product of the higher fatty acid, and may be a mixture of the salt of the higher fatty acid and the higher fatty acid in the above ratio.

[(B) High fructose corn syrup]
In a narrow sense, high fructose corn syrup refers to glucose modified to fructose with an alkali or the like, but in the present invention, saccharides such as glucose, lactose, or fructose are isomerized with an enzyme or alkali. In the present invention, the mixture thereof is also collectively referred to as "isomerized sugar". The saccharides may be industrially synthesized or separated and purified from grains. These single sugars can be isomerized with an enzyme or alkali to obtain high fructose corn syrup. In addition, a single saccharide isomer obtained as needed can be mixed and used.

Furthermore, a mixture of saccharide isomers can be directly obtained from a mixture of saccharides. For example, an isomerized sugar mixture can be obtained by isomerizing a sugar mixture obtained from cereals or the like with an enzyme or an alkali.

In the present invention, the isomerized sugar is preferably an isomerized glucose, lactose, or fructose, or a mixture thereof. Furthermore, fructose is purified by subjecting glucose to an isomerization reaction, while some of the glucose remains unreacted. Therefore, a typical high fructose corn syrup is a mixture of glucose and fructose. In addition, either an enzyme or an alkali is used for the isomerization reaction. As the alkali, a dilute alkaline aqueous solution, for example, a dilute aqueous solution of sodium hydroxide or potassium hydroxide is generally used. As the enzyme, amylase or the like is generally used. The mixing ratio of these sugars is not particularly limited, but the glucose content is preferably high, and specifically, the glucose content is 45 to 55% by mass based on the total mass of isomerized sugars. Is preferable. Various types of such isomerized sugars are commercially available, and for example, pentabitin (trade name, manufactured by DSM Co., Ltd.) is known.

In the present invention, the polymer having a cationic group needs to have a cationic group, but the polymer itself does not have to be a cationic polymer. Rather, in the present invention, the use of amphoteric polymers such as diallyldialkyl quaternary ammonium salt / acrylamide / acrylic acid copolymers tends to provide better effects.

The polymer having a cationic group in the present invention preferably has a low spinnability. It is considered that such a polymer having a cationic group has an effect of improving so-called water solubility, which facilitates diffusion into water when the cleaning agent comes into contact with water.
