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. The compounding ratio of (oily component):(betaine) is 10:1 to 1:10, i.e., 0.1-10 pts.wt. of betaine is compounded based on 1 pt.wt. of oily component. Glycine betaine is used as the betaine and the oily component is selected from oil and fat, wax, hydrocarbon, higher fatty acid, higher alcohol, ester, essential oil, silicone, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is a blend of betaine,
The present invention relates to a bath agent having a smooth skin upon bathing and a moisturizing feeling 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 problems, the present inventors have found that a bath agent containing betaine provides skin smoothness during bathing and a moisturizing sensation after bathing. Therefore, the present invention has been completed.

That is, the present invention is as follows. (1) A bath agent composition containing betaine. (2) The bath agent composition according to (1), characterized in that 0.1 to 10 parts by weight of betaine is added to 1 part by weight of the oil component.

Hereinafter, the bath agent composition represented by (1) or (2) is referred to as the bath agent composition of the present invention.

Betaine has a structure represented by the following formula I and, in a broad sense, is generally used for an inner salt having a quaternary ammonium as a cation in one molecule and an acid, particularly an anion of 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 refers to 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 and the like, and is obtained by separating and concentrating molasses produced as a by-product when sugar is produced from sugar beet etc. by a chromatographic method or the like. be able to.

The betaine of the present invention is 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, based on the bath water.

The effect of the bath agent composition of the present invention is that the skin feels smooth during bathing and gives a moisturizing sensation after bathing. It is preferable to add an oily component to enhance the moisturizing sensation.

Examples of the oily component include those shown below.

2) Waxes Carnauba wax, whale wax, beeswax, lanolin, etc.

3) Hydrocarbons Liquid paraffin, petrolatum, paraffin, microcrystalline wax, ceresin, squalane, pristane, etc.

4) Higher fatty acids Lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, linoleic acid, linolenic acid, lanolinic acid, isostearic acid and the like.

5) Higher alcohols Lauryl alcohol, cetyl alcohol, stearyl alcohol, oleyl alcohol, cholesterol, 2-hexyldecanol and the like.

6) Esters Cetyl octanoate, myristyl lactate, cetyl lactate, myristyl myristate, isopropyl palmitate, isopropyl adipate, butyl stearate, decyl oleate, cholesterol isostearate and the like.

7) Essential oils

8) Silicones

When an oily component is added to the bath agent composition of the present invention, the compounding ratio is as follows: oily component: betaine = 10: 1
~ 1:10, i.e. betaine to 1 part by weight of oil component
It is preferable to add 0.1 to 10 parts by weight.

When the blending ratio is within the above range, there is no sticky feeling peculiar to the oily component, so that the feeling of use of the bath agent composition of the present invention is further enhanced.
