Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery or liquid bath agent composition capable of reliably exhibiting an excellent warm bath effect, cleaning effect, etc. when added to a bath water.

[0002]

2. Description of the Related Art Conventionally, crude drug powders, crude drug extracts, antiphlogistics, enzymes, cell activators, ultraviolet absorbers, etc. have been known as materials which are added to bath agents to exert a warm bath effect and a cleaning effect. And is blended in various bath agents depending on the purpose. Such a material is expected to exhibit an excellent warm bath effect and cleaning effect, but it is hard to say that the action is necessarily certain.

The bath agent is usually used by being put into a bath water obtained by boiling tap water, but tap water is generally subjected to chlorine treatment. This chlorine acts on the sterilization, disinfection, and bleaching of water in tap water, suppresses the growth of bacteria, and is a component obliged to be treated by the Water Supply Act in order to ensure sanitation of tap water. It is known that this chlorine is present as free residual chlorine in tap water, has the effect of suppressing the activation of cells on the skin surface and reducing the elasticity of the skin.

It is also known that the free residual chlorine in the tap water oxidizes and decomposes the pigment component in the bath agent and affects the coloring of the bath water. It has been proposed to incorporate ascorbic acid or a salt thereof in a bath agent as a component for preventing the effect of free residual chlorine on the dye and stabilizing the dye in the bath water.

However, it is not known that the free residual chlorine affects the hot bath effect and the cleaning effect of the bath agent.

[0006] As the action of the ascorbic acid or a salt thereof incorporated into the bath agent, in addition to the above-described pigment stabilization, a medicinal action as a vitamin and an antioxidant action during storage of the bath agent components are known. Only.

Sodium thiosulfate is a component which has been conventionally used as a main raw material for bath agents, together with sodium carbonate, sodium hydrogen carbonate and the like. In the bath agent, sodium salt binds to proteins on the skin surface. However, it is blended to form a film on the skin surface and obtain a moisturizing effect to prevent the dissipation of body temperature.

[0008]

The object of the present invention is to provide an excellent warm bath effect and cleaning effect when the bath agent is added to the bath water.
An object is to provide a bath agent that can be reliably exhibited.

[0009]

According to the present invention, (A)
Ascorbic acid, ascorbate, sodium thiosulfate or a mixture thereof, and (B) crude drug powder, crude drug extract,
An anti-inflammatory agent, an enzyme, a cell activator, an ultraviolet absorber or a mixture thereof is contained as an essential component, and the component (A) is blended in an amount necessary to remove free residual chlorine in the bath water. A bath agent composition is provided.

Hereinafter, the present invention will be described in more detail. The bath agent composition of the present invention comprises a specific amount of the component (A) consisting of ascorbic acid, ascorbate, sodium thiosulfate or a mixture thereof, and a herbal medicine powder known to have a warm bath action and a cleansing action, By combining the component (B) consisting of a crude drug extract, an anti-inflammatory agent, an enzyme, a cell activator, an ultraviolet absorber or a mixture thereof as an essential component, the warm bath effect and the cleaning effect obtained by the ordinary component (B) alone can be obtained. The component (A) is a composition that can be surely exhibited by the action of removing free residual chlorine. Such action and effect prevent the free residual chlorine itself from acting on the component (B), but preventing the free residual chlorine from acting on the skin surface of the bather and inhibiting the absorption of the component (B). It is thought to be to do.

Ascorbic acid used as the component (A), ascorbate such as sodium ascorbate,
Sodium thiosulfate is most preferably powdered in anhydrous form when the form of the bath agent composition is powdered. However, a hydrate can be used as long as the total water content can be preferably 10% by weight or less based on the total amount of the bath agent composition.

The upper limit of the amount of the component (A) to be added is not particularly limited as long as it is at least the amount required to remove free residual chlorine in the bath water into which the bath agent is added. For example, sodium thiosulfate is used. When used in large amounts, slimming may occur in the bathtub, so the upper limit is 0.1% by weight, especially 0.05% by weight, based on the total amount of bath water to be added. It is desirable to do. Specifically, the tap water law defines that the amount of free residual chlorine in tap water must be 0.1 ppm or more (0.4 ppm or more in the case of combined residual chlorine). As a result, about 2 ppm of residual residual chlorine remains when the chlorine concentration is high or at a location. For this reason, for example, in order to add about 200 liters of bath water in a bathtub of a general household, if the amount of the bath agent composition used is 20 g, 0.22 g or more for sodium thiosulfate, 4 g or more for ascorbic acid, and ascorbine. In the case of acid salt, 4.4 g or more is required. This blending amount is the same regardless of whether the bath agent composition is powdery or liquid. At this time, removing free residual chlorine in the bath water does not necessarily mean 100% removal amount.
Even if the amount is usually 50% or more, preferably 80% or more, the desired hot bath effect and cleaning effect can be improved.

The crude drug powder and crude drug extract as the component (B) have an action of stimulating peripheral blood vessels to promote blood circulation, a skin protective action (moisturizing action), etc., and generally exert a warm bath effect or a cleansing effect. It is not particularly limited as long as it is a material known to do, for example, aloe, brown algae, inchinko,
Ougon, Oataku, Gaio, Chamomile, Fern,
Kujin, Keihi, Kouka, Rice germ, Komenuka, Juyaku, Chinpi, Peony, Ginger, Ginger,
Examples thereof include crude drug powders such as ginger root, senkyu, senburi, soup, clove, capsicum, spruce, spruce, carrot, garlic, mint, cypress, loofah, etc. or extracts. Generally, when the bath agent composition is in powder form, crude drug powder is used, and when the bath agent composition is in liquid state, crude drug extract is used, but it can be used as a mixture regardless of the form of the bath agent composition. The blending ratio in the case of containing the crude drug powder and / or the crude drug extract is not particularly limited as long as it is the amount usually used as a bath agent, and is 1% by weight in terms of a crude drug based on the total amount of the conventional bath agent composition. If it is contained as described above, a desired warm bath effect or cleaning effect can be obtained. At this time, the upper limit of the blending ratio can be appropriately determined in relation to the other blending components.

The anti-inflammatory agent as the above-mentioned component (B) is not particularly limited as long as it is a material which is usually blended in a bath composition and is known to exhibit a cleaning effect by anti-inflammatory, for example, allantoin, dipotassium glycyrrhizinate. , Guaiazulene, sodium guaiazulene sulfonate, and the like. The blending ratio of the anti-inflammatory agent is not particularly limited as long as it is an amount usually used as a bath agent, and is preferably 0.01% by weight or more based on the total amount of the usual bath agent composition. The cleaning effect can be obtained. At this time, the upper limit of the blending ratio can be appropriately determined in relation to the other blending components.

The enzyme as the component (B) is not particularly limited as long as it is a material known to be usually blended in a bath agent composition and acting on the skin surface of a bather to exert a cleansing effect. Examples include proteolytic enzymes of microbial origin, lipolytic enzymes of microbial origin, proteolytic enzymes of animal origin, lipolytic enzymes of animal origin (pancreatin, etc.), proteolytic enzymes of plant origin (papain, bromelain, etc.), etc. You can The enzyme is used as an essential component of the component (B), that is, a composition in which the component (A), the enzyme, and a component (B) other than the enzyme are combined as an essential component to obtain a warm bath effect and cleanliness. It is the most preferable composition because the effect can be more reliably exhibited. The mixing ratio in the case of containing the enzyme is not particularly limited as long as it is the amount usually used as a bath agent, and in 100 g of the usual bath agent composition,
15000 pu. If the above content is contained, a desired cleaning effect can be obtained. At this time, the upper limit of the blending ratio can be appropriately determined in relation to the other blending components.

The cell activating agent as the above-mentioned component (B) is a material which is usually blended in a bath composition and is known to exert a cleaning effect by activating cells by acting on the skin surface of a bather. It is not particularly limited, and examples thereof include placenta extract, hinokitiol, vitamin E and the like. The mixing ratio in the case of containing the cell activating agent is not particularly limited as long as it is an amount usually used as a bath agent,
A desired cleaning effect can be obtained by containing 0.001% by weight or more based on the total amount of the conventional bath agent composition. At this time, the upper limit of the blending ratio can be appropriately determined in relation to the other blending components.

The ultraviolet absorber as the component (B) is
There is no particular limitation as long as it is a material known to be usually blended in a bath agent composition and acting on the skin surface of a bather to exert a cleaning effect by absorbing ultraviolet rays. For example, a benzophenone derivative, a paraaminobenzoic acid derivative, methoxy. Examples thereof include cinnamic acid derivatives and salicylic acid derivatives. The blending ratio in the case of containing the ultraviolet absorber is not particularly limited as long as it is an amount usually used as a bath agent, and if contained in an amount of 0.001% by weight or more based on the total amount of the usual bath agent composition, A desired cleaning effect can be obtained. At this time, the upper limit of the blending ratio can be appropriately determined in relation to the other blending components.

The above-mentioned component (B) can be blended alone or as a mixture, but it is preferable to use it as a mixture with an enzyme as described above.

In the bath agent composition of the present invention, in addition to the essential components (A) and (B), the component (A)
It is also possible to add other well-known bath agent components that are not used in the usual bath agents, various stabilizers, surfactants, dyes, perfumes, and the like.

In order to prepare the bath agent composition of the present invention, when the bath agent composition is made into a powder, a method of mixing each component as a powder having a desired particle size, a capsule or a granulated product, etc. Can be obtained by At this time, the water content in the composition may be blended as a hydrate so that the content of water is preferably 10% by weight or less, but it is particularly desirable to blend in an anhydrous form. On the other hand, when the bath agent composition is in a liquid state, the components (A) and (B) are desired in water or an organic solvent such as dipropylene glycol, ethanol, 1.3-butylene glycol, isoprene glycol, or glycerin. It may be added in an appropriate amount so as to exert the effects. At this time, in order to effectively exhibit the warm bath effect and the cleaning effect even during long-term storage, it is desirable to adjust the pH of the liquid bath agent composition to 6 to 9, particularly 7 to 8. This pH adjustment can be carried out by adding a commonly used pH adjusting agent such as disodium hydrogen phosphate and citric acid.

[0021]

INDUSTRIAL APPLICABILITY The bath agent composition of the present invention contains a specific amount of the component (A) for removing free residual chlorine in the bath and a component (B) having a warm bath effect and a cleaning effect in combination. Therefore, the excellent hot bath effect and cleaning effect of the component (B) when the bath agent is added to the bath water can be reliably exhibited.
Further, by using a mixture containing an enzyme as an essential component as the component (B), the effect can be further ensured. Furthermore, when the bath agent composition is liquid, the pH is adjusted to 6
By adjusting to 9 to 9, the desired excellent effect can be exhibited even during long-term storage.
