Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bath agent composition that has excellent heat retention properties and makes the skin smooth.

[Conventional technology]

Hot springs have been widely used and enjoyed by people since ancient times. In response to the desire to easily enjoy the various benefits and comfort that hot springs provide to the mind and body at home, a variety of bath additives have been developed and put into practical use.

Usually, this type of bath salt contains hot spring ingredients such as mirabilite, baking soda, and inorganic salts such as salt to provide heat retention, and it also contains coloring agents and other additives to improve the color tone. There are many (for example, see JP-A-59-148716@). .

It is also already known that various oils are used to make the skin smooth (for example,
(See No. 7).

[Problem that the invention seeks to solve]

However, conventional bath agent compositions have not yet achieved a sufficient heat retention effect, and there has been a need for one with even better heat retention effects.

In other words, in the case of bath salts using glauber's salt, common salt, etc., the heat retention effect is only about 1.4 times that of hot water at most, and there has been a desire for bath additives with even higher heat retention effects. In addition, in the present invention, unless otherwise specified, the heat retention effect is measured by the heat retention time after taking a bath).

On the other hand, in terms of imparting smoothness to the skin, there are problems in that depending on the quality and quantity of the oil, it may stain the walls of the bathtub, and when it is formulated and stored, its commercial value may decrease due to oxidation.

In addition, there was also the problem that too much oil made the skin sticky and weakened the bathing window.

(Means for Solving the Problems) As a result of intensive research in order to obtain a bath agent composition that does not have the above-mentioned problems, has excellent heat retention properties, and makes the skin smooth, the present inventor has identified magnesium sulfate. They have discovered that this can be achieved by a combination of the following compounds, and have completed the present invention.

That is, the present invention provides a bath agent composition characterized by containing magnesium sulfate and a compound having a hydroxyl group and/or a compound having an aldehyde group.

The present invention will be explained in detail below.

Magnesium oxide (MQSOa), which is an essential component of the bath agent composition of the present invention, is not particularly limited in its production method and does not matter whether it is an anhydrous hydrate or not, but heptahydrate and trihydrate salts are preferable. .

The blending amount of magnesium sulfate is preferably 20 to 70% by weight. If it is less than 20 parts by weight, the heat retention effect will be short, and if it exceeds 70 parts by weight, it will be difficult to obtain smooth skin.

The particle size of magnesium sulfate is preferably 20 to 150 mesh. This is because when a substance within this range is used, segregation does not occur when mixed with other formulations, and appropriate fluidity can be imparted to the formulation.

Next, the compounds having a hydroxyl group used as one of the essential components of the bath agent composition of the present invention are cis-3-hexenol, 2
-cis-3,7-dimethyl-2゜6-octadiene-1
-ol, 3.7-dimethyloctanol-3.5-methyl-2-isopropylcyclohexanol, dimethylphenylethyl alcohol, phenyl impropyl alcohol, linaxol, 3,7-dimethyl-1,6-octadien-3-ol, Bornylmethoxycyclohexanol, 2-trans-3,7-dimethyl-2,6-
One or more compounds selected from octadien-1-ol and 2-phenylethanol. Similarly, compounds having an aldehyde group include octanal, nonal, decanal, hexadecylaldehyde, α-n-
Hexylcinnamic aldehyde, 3,4-methylenedioxybenzaldehyde, p-isopropyl-α-methylhydrocinnamic aldehyde, p-tetra-butyl-α-methylhydrocinnamic aldehyde, and 4-methylenedioxybenzaldehyde.
One or more compounds selected from -(4-hydroxy-4-methylpentyl)-3-cyclohexene-1-carboxaldehyde.

The compound having a hydroxyl group and the compound having an aldehyde group may be used alone or in combination with magnesium sulfate.

The blending amount thereof is preferably 0.05 to 2.5 parts by weight.

If it is less than 0.05 parts by weight, no heat retaining properties can be obtained, and if it exceeds 2.5 parts by weight, it is undesirable because it is too irritating to the skin.

The composition of the present invention may also contain the following additional components that have been conventionally used as bath additives.

In addition to the above, the bath agent composition of the present invention also has the following features:
A wide range of other additives such as sterilizing preservatives, sequestrants, fragrances, and others can be added as required.

Next, a method for manufacturing the bath agent composition of the present invention will be explained.

First, a conventional bath agent composition of 20 to 70 parts by weight of magnesium sulfate, 2.5 parts by weight of either or both of a compound having a hydroxyl group and a compound having an aldehyde group, and sodium hydrogen carbonate, sodium sulfate, etc. Ingredients used as raw materials for products are added to make the total 100 parts by weight,
Pour this mixture into a mixer and stir evenly at room temperature.
Mix.

As the mixer, any device can be used as long as it is used for stirring and mixing powders. Specific examples include a part mixer, a Nauta mixer-1 all-purpose stirring mixer, a ribbon mixer, and a square-shaped mixer.

The mixing time may be any time necessary to uniformly mix the components, and when using the mixer mentioned in the above example, it may normally be 5 to 50 minutes.

〔Example〕

The present invention will be specifically explained below with reference to Examples and Comparative Examples.

Examples 1-8. Comparative Examples 1 to 8 Each component shown in Table 1 was put into a universal stirring mixer (25AM-rr (Qr) manufactured by Sanei Seisakusho) in the proportion ω shown in the same table,
The mixture was stirred and mixed for 10 minutes. A compound having a hydroxyl group or a compound having an aldehyde group shown in Table 1 was added thereto, and the mixture was stirred and mixed in the above-mentioned mixer for 10 minutes to prepare each bath agent composition shown in Table 1. Comparative Examples 1 and 5 are examples of bath agent compositions that do not contain a compound having a hydroxyl group or a compound having an aldehyde group, and Comparative Examples 2 to 4 and 6 to 8 use sodium chloride instead of magnesium sulfate. This is an example.

Examples 7 and 8 are examples showing the influence of the amount of magnesium sulfate.

A bathing test was conducted for each of the prepared bath agent compositions, and subjective evaluations were made.

The results are shown in Table 1.

The bathing test was conducted as follows.

Number of panelists: 10 people Prescription: Shown in Table 1 Temperature of bath water: 41°C Usage fee for bath agent composition: 30g/200N Bathing time:
5-minute subjective evaluation method: After taking a bath, maintain a resting state in a constant temperature room at 20°C Evaluation items and details: 1) Regarding skin smoothness, "no change" is scored as 0, and "skin becomes very smooth" as 10 Scores were evaluated on a 10-point scale, and the average value of the 10 participants was shown.

2) Regarding feeling of warmth, a subjective evaluation was made of the time until the feeling of hot flashes on the body surface disappears after bathing, and the relative time was calculated with 1.0 in the case of dry bathing and expressed as the average value of 10 people.

(The following is a blank space) As is clear from Table 1, the bath agent compositions of the present invention [Examples (1, 2, 3, 4, 5 and 6)] They also showed high numerical values of 7 to 9 and 1.8 to 2.1, respectively, and had excellent effects.

On the other hand, Comparative Examples 1, 2.3.4, 5.6°7 and 8
was rated 1-2 in terms of skin smoothness, and was not very effective compared to Nara-yu.

In addition, the feeling of warmth after bathing was not as high as that seen in the bath agent composition of the present invention compared to the saraha.

In addition, although there is a difference in the feeling of warmth in Example 7, there is no difference in the smoothness of the skin, and in Example 8, contrary to Example 7, there is no difference in the smoothness of the skin. However, no significant difference was observed in the feeling of warmth.

From the above test results, it can be said that the bath agent composition according to the present invention is excellent in both skin smoothness and warming feeling.
