Abstract

PURPOSE:To obtain a bathing agent giving smooth feeling to the skin in bathing and moist skin after the bath. CONSTITUTION:The characteristic of this bathing agent composition is the compounding of betaine and an alkaline agent. Glycine betaine is used as the betaine and any inorganic salt such as sodium bicarbonate, sodium carbonate, borax and sodium metasilicate can be used as the alkaline agent provided that the salt exhibits weak alkaline nature when dissolved in bath water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath agent containing betaine and an alkaline agent, which gives the skin smoothness during bathing and has a moisturizing sensation after bathing.

[0002]

2. Description of the Related Art Conventionally, bathing has the effects of cleansing the body, promoting blood circulation, and relaxing mentally, and is greatly involved in coldness and recovery from fatigue. On the other hand, bathing causes loss of oil content, natural moisturizing factor (NMF) components, etc. from the skin, and the resulting dryness of the skin after bathing is caused by dry skin, senile psoriasis or atopic dermatitis. It is a serious problem for people with illness.

[0003] In response to such problems, it has been desired recently that the skin feels smooth when bathing and the skin after bathing is moist, and various bath agents have been proposed to meet the demand.

Generally, for the purpose of moisturizing and protecting the skin,
Although an oily component is mixed and dispersed in a bath water, there is a problem that the skin becomes sticky during and after bathing and the usability is not good.

Therefore, there has been a demand for the development of a bath agent which provides a smooth skin upon bathing and a sufficient moisturizing effect after bathing.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that a bath agent containing betaine and an alkaline agent gives the skin smoothness during bathing and moisturizes after bathing. It was found that the feeling was obtained, and the present invention was completed.

That is, the present invention is a bath agent composition (hereinafter referred to as the bath agent composition of the present invention) characterized by containing betaine and an alkaline agent.

Betaine has a structure represented by the following formula I, and, in a broad sense, generally refers to an inner salt having a quaternary ammonium as a cation in one molecule and an anion of an acid, particularly a carboxylic acid. It is the name and can be obtained by alkylation of amino acids or reaction of halogen substituted carboxylic acids with tertiary amines. Further, since it is possible to change a water-insoluble polymer into a soluble compound, it is used as a surfactant, an emulsifier, a dye and a preservative.

Formula I (In the formula, R ₁ , R ₂ and R ₃ are the same or different and each represents an alkyl group.)

Here, betaine in the present invention means glycine betaine in which all R in the above formula I are substituted with a methyl group, that is, glycine completely N-methylated.

The betaine of the present invention is contained in the juice of sugar beet, etc., and is obtained by separating and concentrating molasses, which is a by-product when sugar is produced from sugar beet etc., by a chromatographic method or the like. be able to.

Further, as betaine of the present invention, Cultar
It does not matter if you use the products sold under the trade name of "NATURAL EXTRACT AP" manufactured by Ltd.

The mixing ratio of betaine in the bath agent composition of the present invention is preferably 0.01 ppm to 100 ppm, more preferably 1.0 ppm to 20 ppm with respect to the bath water.

[0014] The bath agent composition of the present invention has an effect that the smoothness of the skin during bathing and a high moisturizing feeling after bathing can be obtained by using an alkaline agent as an essential component.

The alkaline agent used in the present invention includes:
Any inorganic salt or the like that exhibits weak alkalinity when dissolved in a bath may be used, and specific examples thereof include sodium hydrogen carbonate, sodium carbonate, borax, sodium metasilicate, and the like. Is preferred.

In order to maximize the effects of the bath agent composition of the present invention, it is necessary to mix an alkaline agent with betaine to remove excess sebum from the skin so that the betaine easily adheres to the skin. However, it is not preferable to add a high-concentration alkaline agent such that the pH of the bath water exceeds 9.5, because the effect of betaine will be lost.

Therefore, the content of the alkaline agent in the bath agent composition of the present invention is preferably adjusted so that the pH of the bath water is 9.0 or less.
