Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bath agent composition containing a plurality of components, and also relates to a bath agent composition that is used in combination with bath equipment.

<Prior Art> For example, as disclosed in Japanese Unexamined Patent Publication No. 166607/1983, a bath additive containing ethylene glycol as a main ingredient, a so-called bath additive, is well known.

Furthermore, ethylene glycol is widely used as a binder for conventionally compressed bath preparations or as a solvent for pigments in powdered bath preparations.

<Problems to be Solved by the Invention> However, conventional bath additives containing polyethylene glycol have the following problems.

a) Stability at high temperatures and/or high humidity was poor, and powdered bath additives agglomerated and blocked into a solid form over time.

b) When the content of polyethylene glycol was 50% by weight, so-called the main component, it caused skin irritation.

C) When using a bath agent composition that uses only polyethylene glycol as a foaming component and trying to promote foaming by bath equipment, the foaming is good, but the foam does not break easily and may require hot water after getting out of the bath, or may cause damage to the body. Even after wiping it off, it remained on the skin, causing skin irritation even after bathing.

e) Bath agent compositions containing polyethylene glycol as a main component had poor cleaning effects during bathing. Furthermore, even when used in combination with bath equipment, there have been problems such as not being able to sufficiently promote the inherent cleaning effect of the bath equipment.

The object of the present invention is to provide a bath composition that solves the above problems.

<Example> The present invention will be described in more detail below based on examples thereof.

Comparison of physical property stability at high temperature and/or high humidity [Example 1], skin irritation of the bath composition according to the present invention and a conventional bath composition containing polyethylene glycol (Safety) comparison [Example 2
], Comparison of hot bath effect, cleaning effect, pine surge effect, foaming, and foam breakage when used in combination with bath equipment [Example 3]
Comparison of solubility in bath water [Example 4] was evaluated.

The results for each example will be shown below, but the present invention is not limited to these examples, and similar results can be obtained if the bath agent composition according to the present invention described above is used.

[Example 1] Regarding the bath agent compositions shown in Table 1, 100 bottles each of the bath agent compositions were filled into predetermined containers, sealed, and kept at room temperature and temperature 4.
Fifty bottles each were stored under two storage conditions of 0° C. and 70% humidity, and the anti-blocking effect of polyethylene glycol was visually judged. The results are shown in Table 2. From Table 2, it is clear that the products of the present invention are superior to the conventional products in physical property stability at high temperatures and/or high humidity. This is because by blending starch hydrolyzate and/or silicic acid compound, the starch hydrolyzate and/or silicic acid compound adheres to the surface of polyethylene glycol molecules, and agglomerates due to melting of polyethylene glycol due to high temperature and high humidity. (blocking) can be prevented.

Table 1 Table [Example 2] Regarding the bath compositions shown in Table 3, the bath composition liquid concentration was 5 times higher than the concentration normally used (dissolve 20 to 25 g in 180 to 200 g of a household bathtub and take a bath). A 24-hour closed batch test was conducted on the composition liquid. The experiment is
A certain amount of the sample is dropped onto each spot, immediately attached to the inside of the upper tile of the subject, and removed after 24 hours. The local condition 1 hour, 24 hours, and 48 hours after removal was evaluated using the following evaluation criteria, and the results are shown in Tables 4 and 5.
And Table 5 clearly shows that the bath composition according to the present invention is
It is clear that it is superior to conventional products in terms of irritation. This reduces the skin irritation of polyethylene glycol or surfactant due to the reduced amount of polyethylene glycol and the skin protective effect of starch hydrolyzate.

〔Evaluation criteria〕

m: No reaction ±: slight erythema 12 erythema ++: erythema and edema or erythema and papules +++: small varicella ++ large hydration or erosion Table 6 [Example 3] Table 6 A practical usability test was conducted using N=50 for the bath agent composition shown in 1 when used in combination with bath equipment configured to insert compressed air into bath water to cause foaming and circulation. The results are shown in Table 7.

From Table 7, it is clear that the product of the present invention can be used for hot bathing, washing, pine surgery,
It is superior to conventional products in terms of foaming and foaming effects.

The synergistic effect of polyethylene glycol and surfactant makes it possible to create fine bubbles, and the generation of these fine bubbles stimulates the skin surface, improves the dilation of peripheral blood vessels, and promotes the warm bath effect. In addition, the fine bubbles also promote the pine surge effect. Furthermore, by containing an enzyme, in addition to physically cleaning the foam, it is possible to promote the cleaning effect by making dirt easier to remove. Furthermore, it is clear that the suds can be quickly removed after the bath equipment is stopped.

Table [Example 4] Regarding the bath agent compositions shown in Table 8, a solubility test when added to bath water was confirmed using a N=50 monitor. 20g of the bath preparation composition was added to about 200β hot water, and the temperature of the bath water was 40°C. The results are shown in Table 9. It is clear from Table 9 that the product of the present invention has better solubility than the conventional product.

Table 8 Table <Effects of the Invention> As described above, the present invention has non-blocking properties that could not be obtained with conventional polyethylene glycol-based bath preparations, is non-irritating to the skin, and does not cause foam breakage. Moreover, it has an excellent cleaning effect during bathing, and furthermore, when used in conjunction with bath equipment, it has the effect of sufficiently promoting and promoting the foaming, cleaning, and other effects inherent in the bath equipment.
