Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath preparation composition which does not have a sticky feeling after bathing, has excellent skin smoothness during bathing, and has an excellent moisturizing effect after bathing.

[0002]

2. Description of the Related Art Bath compositions generally include sodium sulfate,
Inorganic salt mixtures such as sodium bicarbonate, flavors, pigments,
A compound containing a moisturizing agent or the like, which imparts aroma and color tone to the bath water, recovers fatigue by the effect of promoting the blood circulation and the heat retaining effect by the action of inorganic salts, and gives a feeling of relaxation.

[0003] On the other hand, recently, diversification of consumer needs has demanded a bath agent having a beautiful skin effect.

[0004]

In order to meet such demands, various bath compositions have been proposed.
Few consumers can get satisfaction, and each of them has some problems. For example, there is a case using an oil component, but in order to obtain the effect, it is necessary to increase the amount of the oil, which often causes problems such as sticky skin and bathtub stains with oil after bathing. . In addition, a composition containing a milk component such as skim milk powder has been proposed, but there were problems such as the milk component aggregating and floating on the surface of the hot water and generating an unpleasant odor due to the daily change of the product.

The present invention has been made under such circumstances, and has no sticky feeling after bathing, and has excellent skin smoothness at the time of bathing and an excellent moisturizing effect after bathing. It is intended to provide an agent composition.

[0006]

Means for Solving the Problems As a result of intensive studies on the combinations of various compounds, the present inventors have surprisingly found that lactose, rice germ oil or rice bran oil, a cationic polymer, and isostearyl alcohol are included. It has been found that the combination of two or more can achieve the above object of the present invention. That is, the present invention resides in a bath agent composition containing at least two or more selected from the group consisting of lactose, rice germ oil or rice bran oil, a cationic polymer, and isostearyl alcohol.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.

The cationic polymer may be used alone or in combination of two or more. The amount is preferably 0.2 to 5.0% by weight based on the total amount of the bath composition of the present invention. Hereinafter, abbreviated as wt%), more preferably 0.5%.
３3.0 wt%. If the amount is less than 0.2% by weight, good effects on the smoothness of the skin during bathing may not be obtained. Moist effect is not obtained,
May not be preferred.

The amount of isostearyl alcohol used in the present invention is preferably 0.1 to 5.0% by weight, more preferably 0.3 to 5.0% by weight based on the total amount of the bath composition.
3.0 wt% is blended. If the amount is less than 0.1%,
Good effect may not be obtained on the smoothness of the skin when taking a bath and the moistening effect of the skin after taking a bath.
If it exceeds 300, the skin after bathing tends to be sticky and unfavorable.

The rice germ oil used in the present invention is rice [Or
