Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath composition which contains coconut milk and is excellent in moisturizing effect and long-term stability.

[0002]

2. Description of the Related Art Conventionally, in order to enhance the bathing effect, a wide variety of bath agents used by being added to bath water have been developed and used. As typical examples thereof, sodium sulfate, sodium hydrogen carbonate, borax, sodium sesquicarbonate and the like as a main agent, a powder or granular bath agent in which a dye, a fragrance, a bactericide and the like are added, lanolin, a lanolin derivative, Softeners such as isopropyl myristate, isopropyl alcohol, squalane, pyrrolidonecarboxylate, glycerin, propylene glycol, and other animal and vegetable oils and fats and their softeners are used as the main ingredients, and coloring agents,
Many liquid bath agents containing fragrances, germicides and the like are commercially available. In addition, these bath agents enhance the heat retention effect,
Attempts have been made to add various plant components for the purpose of improving various effects such as cleansing or beautiful skin, beauty effect, moisturizing and smoothing effect of skin, and deodorant effect.

However, many of the conventional plants used as raw materials for plant components are valuable plants that are distributed only in a limited area, and their growth varies depending on the weather, etc., so that the raw materials are stable and available in large quantities. It was difficult and costly. Therefore, in order to solve such problems and further respond to the recent diversification and sophistication of consumer needs for bath agents, an excellent bath agent formulation that is relatively easy to obtain and has new efficacy. The development of plant ingredients for plants was awaited. In view of such circumstances, it is an object of the present invention to provide a novel bath agent composition that uses a highly safe plant component that exhibits an excellent bathing effect.

[0004]

Means for Solving the Problems As a result of repeated studies on various plants in order to solve the above problems, the present inventors have found that the use of coconut milk results in a moisturizing effect on the skin.
The inventors have found that a bath composition having a (moisturizing effect) can be obtained, and have completed the present invention. That is, the present invention is a bath agent composition containing coconut milk (hereinafter referred to as the bath agent composition of the present invention).

Coco coconut (scientific name: Cocos nucifera) is a kind of palm that has large fruits and has a large bamboo shoot in the tropical lowlands, especially near the coast. The stem reaches a height of 20 to 30 m and does not branch, The diameter is 20 to 30 cm and the roots are thick. Leaves on the tip of the stem
Gather 20 to 30 pieces and open in all directions. The fruit is slightly egg-shaped and has three blunt edges. The length is 25 to 30 cm, the diameter is 20 to 25 cm, and the base has a swelling piece after flowering. Epicarp is thin, ripe and brown, mesocarp is brown and thick, fibrous and its inner core
(Inner skin) almost spherical, hard, dark brown, 3-5 m thick
m, 3 concave points at the base, and one of them germinates. 2-3 cm thick inside the thin seed coat that contacts the inner surface of the nucleus
There is a grayish-white, fatty endosperm, and a large empty space in the center is filled with liquid. Coconut milk is this endosperm, and dried endosperm is copra.

As the coconut milk used in the present invention, endosperm and dried endosperm (copla) can be used, and the coconut milk can be appropriately selected and used depending on the dosage form of the bath composition. Coco palm is cultivated in many tropical regions of the world, especially in the Asian region, and there is no problem in terms of supply and cost.

In the present invention, as the other bathing agent composition to be blended with the coconut milk, any bathing agent composition which can be usually used as a bathing agent raw material can be used, but depending on the intended effect and effect of the bathing agent, It suffices to appropriately select and blend from the following.

[0021]

In the present invention, by adding coconut milk to the raw material of the bath agent, a very good moisturizing effect,
A bath agent composition having a cosmetic effect can be obtained. Further, the bath composition of the present invention is stable without being deteriorated for a long time even when mixed with various inorganic salts in the case of powder and granules, and has good compatibility with various raw materials even in the case of liquid, It has the effect of being stable for a long period of time. Even if the powder formulation containing conventional plant ingredients is good at the time of manufacture,
When stored for a long time, changes in bath components tend to occur,
Further, the color tone and scent of the preparation are likely to change, and further, in the liquid preparation, turbidity or separation is likely to occur when stored for a long time. On the other hand, the bath composition of the present invention in which coconut milk is added to the bath raw material is stable for a long time regardless of whether the dosage form is a powder formulation or a liquid formulation, and deterioration of quality is observed. Has the effect of not. Further, the bath agent composition of the present invention has a non-greasy, moist and comfortable feeling on the skin (moisturizing effect), and has an excellent effect as a bath agent.
