Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to bath additives. More specifically, the present invention relates to bath additives using cyclodextrin.

[Prior art]

Milk baths have been said to be good for beauty since ancient times. In fact, the active ingredients in milk have a beautifying effect on the skin. However, in reality, it is hardly used as a bath additive. The reason for this is that milk is perishable and easily putrefied, making it difficult to industrially produce and manage it as a bath additive, and that milk has a unique odor, which people either like or dislike.

[Purpose of the invention]

An object of the present invention is to use a milk component such as milk that is hard to putrefy and to use it in a bath salt to enhance the skin beautification effect during bathing.

[Structure of the invention]

The bath additive of the present invention is characterized by containing a clathrate compound in which a milk component is encapsulated with cyclodextrin, and preferably also contains vitamins.

The method for producing bath additives of the present invention includes milk, milk components,
The feature is that a milk component selected from a group consisting of powdered milk, evaporated milk, evaporated milk components, fresh cream, and fresh cream components is made into a clathrate compound with cyclodextrin, and then mixed with other bath agent ingredients. That is.

The above-mentioned bath agent raw materials can be in the form of powder, granules, tablets, crystals, or pastes, and medicinal herbs can be used in their original form or in a finely divided form.

The clathrate compound of the milk component to be mixed with these bath agent raw materials may be produced by a saturated aqueous solution method or a kneading method. That is, a clathrate compound is obtained by adding a certain amount of milk components to a saturated or supersaturated aqueous solution of cyclodextrin and stirring the mixture for several tens of minutes to several hours. Alternatively, the clathrate compound can be obtained by adding water to cyclodextrin to form a slurry, adding the required amount of milk components, and thoroughly stirring and mixing using a kneader or the like.

The clathrate compound thus obtained is washed with water if necessary and dried by spray drying, ventilation drying, freeze drying, etc. to obtain a powdery clathrate compound.

As the milk component to be clathrated, one or more of milk, milk component, powdered milk, evaporated milk, evaporated milk component, fresh cream, fresh cream component, etc. may be used.

The cyclodextrin may be α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, or a mixture thereof, and may be used in powder form, or starch decomposition products containing cyclodextrin (for example, Celldex CH-20 (manufactured by Nihon Shokuhin Kako Co., Ltd.) may also be used.

The ratio of the guest milk component to the host cyclodextrin is not particularly limited as long as it can clathrate the milk component. For example, the molar ratio is 1:1
It may be a degree.

For example, 80 parts by weight of Celldex CH-20 (Nihon Shokuhin Kako Co., Ltd.), 20 parts by weight of milk ingredients, and 80 to 160 parts by weight of water are mixed and stirred at a temperature of 70°C or less for several hours to dissolve the milk ingredients. It is clathrated with cyclodextrin, and this clathrate compound is dried to form a powder.

Then, this powdered milk component cyclodextrin clathrate compound is mixed with the other bath agent raw materials mentioned above (water softeners, bleaching, bactericidal, medicinal, etc. substances, fragrances, pigments, etc.), This is the bath additive of the present invention.

Furthermore, it is a good idea to add egg whites and vitamins to enhance the beauty effect.

To add egg white, for example, when including a milk component, the egg white and the milk component may be mixed into an aqueous solution or slurry of cyclodextrin.
After that, when dried, a powder containing egg white is produced, which is mixed with other bath additive ingredients.

Vitamins such as vitamin A and vitamin B
Vitamin C, vitamin D, vitamin E, vitamin F and vitamin P are suitable. Vitamins may be mixed with the milk component into an aqueous solution or slurry of cyclodextrin when including the milk component, but in particular vitamin A,
Fat-soluble vitamins such as D and E are added to a liquid containing the cyclodextrin clathrate of the milk component after clathrating the milk component with cyclodextrin and before drying the clathrate compound.
You can add vitamins. It is then dried at a relatively low temperature to form a powder so that the vitamins are not destroyed.

Note that fat-soluble vitamins deteriorate easily, so
It is advisable to emulsify it in advance before adding it to the clathrate compound-containing liquid. In this case, it is preferable to emulsify using the surfactant effect of cyclodextrin. For example, vitamin oil and water are used in approximately the same molar ratio, and a thickener (such as sodium alginate) and a trace amount of cyclodextrin are mixed and emulsified.

In addition, vitamins themselves are powdered as clathrate compounds using cyclodextrin.
Finally, the cyclodextrin clathrate compound of the milk component may be mixed with other bath agent raw materials.

In addition, for preservative and anti-mold, we use approximately 1% glycine and alcohol emulsified with cyclodextrin.
It is preferable to add it to a liquid containing the cyclodextrin clathrate compound of the milk component in portions and then powder it together with the cyclodextrin clathrate compound of the milk component.

Furthermore, for fragrances, etc., it is possible to mix a small amount of cyclodextrin and emulsify it in advance, add this to a liquid containing a cyclodextrin clathrate compound as a milk component, and then powder it together with the cyclodextrin clathrate compound as a milk component. preferable. The fragrance is not particularly limited, but if a milk flavor or the like is used, for example, the atmosphere of a milk bath can be created even more due to the relationship with the milk component of the clathrate compound.

In general, cyclodextrin inclusion compounds are extremely difficult to dissociate (ring cleavage), and do not dissociate unless the temperature is about 80 to 130°C in a dry state. Therefore, when using the bath agent of the present invention as it is, it is sufficient to dissolve it in hot water before adding it to the bath water.

In this way, the bath agent of the present invention may be dissolved in hot water before use, but at the temperature of ordinary bath water, the cyclodextrin ring dissociates and the clathrated milk components are eluted. It is preferable to keep it as

For the purpose of dissociating cyclodextrin at normal bath water temperatures, it is recommended to use a small amount of saccharifying enzyme. Examples of saccharifying enzymes include α-amylase and cyclomaltodextrin glucanotransferase (cyclomaltodextrin glucanotransferase).
glucanotransferase) etc. may be used. In this case, the milk component may be included in cyclodextrin, dried to form a powder, and then the powdered saccharifying enzyme may be mixed with other bath agent raw materials, or the milk component may be cyclodextrin The dextrin clathrate compound and the saccharifying enzyme are kept in a non-contact state,
It may also be added to the bath together with bath additives. To maintain the non-contact state, for example, the following may be done.

Example 1: A clathrate compound and a saccharifying enzyme are placed in separate containers.

Example 2: A saccharifying enzyme is sealed in a water-soluble pouch, and this pouch is mixed with an inclusion compound and stored in one container.

Example 3: One dose of saccharifying enzyme is sealed in a water-soluble pouch, and each dose of an clathrate compound is sealed together with this pouch in each water-soluble bag.

Example 4: A water-soluble bag is provided with a partition inside,
The clathrate compound is stored in one chamber and the saccharifying enzyme is stored in the other chamber.

When the saccharifying enzyme prepared in this way is poured into a bath, the temperature of the bath water is around 40°C, which is a suitable temperature for the saccharifying enzyme to work, so the ring of the cyclodextrin clathrate compound in the bath agent is acting on,
Dissociate cyclodextrin. As a result, the clathrated milk components are liberated and dissolved in the bath water, producing a beauty effect.
