Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath agent composition for artificial alum fountain containing a turbidity agent, which contains a pigment and a water-soluble aluminum salt but does not cause cohesive precipitation.

[0002]

2. Description of the Related Art Water-soluble aluminum salts represented by alum, aluminum sulfate and the like have long been known as a component of alum springs in hot springs. It is known to have a dry feel. In addition, water-insoluble pigments such as titanium oxide,
It is known that when it is added to a bath additive, the water becomes cloudy, the feeling of hot springs is enhanced by the appearance, and the powder has a dry skin feel.

However, when these are mixed to soak in the mood of a hot spring and prepare an alum spring with an artificial turbidity agent that feels good to the skin, the water-insoluble coagulation action of the water-soluble aluminum salt causes the water insoluble in the bath water. Insoluble matter such as titanium oxide causes coagulation and precipitation, and the bath water becomes transparent. Furthermore, when this is used as a foaming bathing agent composed of a carbonate and a neutralizing agent, white water-insoluble lumps are generated, and since the carbon dioxide gas is contained, the lumps float on the bath water, The appearance is impaired due to the formation of aggregates. For this reason, not only the mood of the hot spring caused by the turbidity agent but also the feel of the skin is impaired, making it impossible to provide an artificially turbid alum spring.

In such a situation, in order to supply a turbid artificial alum spring, a method in which a water-insoluble pigment does not cause coagulation and precipitation even when coexisting with a water-soluble aluminum salt, that is, bath water is used. It is conceivable to formulate the solution so that the pH is 4 or less, or the acidity is 10.5 or more.

[0005] However, making the bath water such a strong acid or a strong alkali not only damages the skin,
As a result of damaging bathtubs and baths, it is difficult to spread them to ordinary households.
