Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to bath additives, and more particularly to bath additives in which squalane is released in a sustained manner in bath water and is evenly dispersed to provide a stable effect.

[Prior Art and Problems to be Solved by the Invention] The custom of adding fragrant bath salts or medicinal bath salts when taking a bath is well-established in both the East and the West.

Generally, bath additives are classified as follows.

Inorganic salt bath salts Sodium chloride, sodium carbonate, potassium chloride It varies depending on the ingredients used, but it can prevent hot water from cooling, remove waste products from the body,
Examples include stress relief and water quality improvement.

Effervescent bath agents Stimulate the skin surface with carbon dioxide gas and air bubbles and promote blood flow, and carbon dioxide gas dissolved in bath water is absorbed by the human body and dilates capillaries to promote blood flow. It has the effect of The former is used for rehabilitation and requires equipment, while the latter is commercially available in drug form.

It uses a water softener such as bath cube phosphoric acid soda and EDT 8 as its base material, and has fragrance added to it.

Medicinal plant bath additives After plants are treated as herbal medicines, they are cut up and packaged in bags, and used as they are or added to bath water along with the decoction, and have various effects.

Bubble baths In bathing methods in which the body is washed with soap in a bathtub and then rinsed off in the shower, high hardness of the water causes problems such as poor lathering and lime sorb which may be harmful to the body and the bathtub. It is used to prevent this, and is a bath additive containing a surfactant.

Bath oil was developed for skin protection and cosmetic purposes, such as replenishing fat lost during bathing and softening and smoothing the skin. Mineral oil is often used as the oil.

Bath Capsule A formulation containing bath oil and bath fume in a soft gelatin capsule, with a diameter of about 3 to 20 mm.
When placed in bath water, the capsule swells and dissolves, and the ingredients inside are dispersed or dissolved in the bath water.

Milk baths are available in emulsion, oil and powder forms and are used for the same purpose as bath oils.

bath liquid It is often seen in Europe and America, and promotes metabolism.

It contains ingredients such as oils, fats, and esters for the purpose of protecting the skin and making it smooth.

passba fume Essential oils are intended for the enjoyment of fragrance.

It is made mainly from fragrance.

Enzyme bath agents are bath agents that use proteolytic enzymes such as papain and vancreatine, and are intended to dissolve and remove unnecessary stratum corneum on the surface of the human body.

Bath sherry formulations are sherry-like and tubes are often used, but the purpose of use, efficacy range, and raw materials are all the same as forming baths and bubble baths.

Among the various bath additives mentioned above, bath oils are of the type that float on the surface of the bath water like a thin film of oil.
There is a type that is dispersed and emulsified in bath water. As a raw material, mineral oil is often used as described above, but other vegetable oils such as castor oil and olive oil, animal oils such as mink oil and squalane, higher alcohols, fatty acid esters, and the like are also used.

Since these bath oils have oil as their main component, they have the fateful problem of being limited to liquid bath additives.

[Means for Solving the Problems] The present inventors found that among the oils used as components of bath additives, squalane is tasteless and odorless, has excellent fragrance retention, and has excellent spreadability, permeability, and texture on the skin. Noting that it has good properties, we investigated how to use this property as a bath additive and used it in combination with cyclodextrin (hereinafter abbreviated as CD). We have found that this is effective and have arrived at the present invention.

That is, the present invention is a bath agent containing as an active ingredient a clathrate compound in which squalane is clathrated with CD.

Squalane is a saturated chain obtained by hydrogenating squalene, which is present in deep-sea shark liver oil, under high temperature and pressure. Squalane is a low-volatility, low-freezing-point oily liquid that has a lighter oily texture than liquid paraffin, and has the property of maintaining a long-lasting scent when fragrances are added to it. Also, it is insoluble in water and almost insoluble in ethanol, acetone, etc., but is miscible with animal and vegetable oils, mineral oils, etc. Furthermore, squalane has better skin permeability and lubricity than lanolin or lard, and is extremely spreadable and emulsifiable, making it extremely useful as an oil phase raw material for cosmetics and the like.

Next, CD is a cyclic oligosaccharide in which multiple glucose molecules are bonded with α-1,4, and various types are known so far.
, 7 of them are β-CD.

The eight pieces are called γ-CD. In addition, these C
DLf) So-called branched CDs in which glucose is bound to IJl are also known. In the present invention, these CDs may be used alone, and 2 f! The above may be used in combination.

Furthermore, these CDs and other ingredients, Tako IJ xB Tun M

Since D exhibits lipophilicity on the inside of its annular structure and hydrophilicity on the outside, it has the effect of incorporating various oily substances into the cavity and stabilizing it.

A method for producing an clathrate compound in which squalane is clathrated with CD will be described below.

Generally, squalane is added to an aqueous solution of CD, and a solution of the clathrate compound is obtained by uniformly stirring and mixing.

Then, if necessary, it is pulverized using an appropriate drying means. Here, the CD concentration in the aqueous solution varies depending on the characteristics of the CD used, especially the solubility, but for example, α-CD, β-CD
When using a CD mixture in which the component ratio of γ-CD is 6:3:1, an appropriate amount is 5 to 50%, preferably 20 to 40%.

Next, the amount of squalane added to CD can be changed as appropriate depending on the desired degree of emulsification when used as a bath additive, but is generally 30 to 60%, preferably 40 to 50%.

As the drying means, volcanic drying, freeze drying, vacuum drying, etc. can be employed, and volcanic drying is particularly preferred. In addition, at the stage of manufacturing the clathrate compound, other ingredients used as bath additives,
For example, fragrances and the like can be added at the same time as the squalane or at an appropriate time.

[Example] Next, the present invention will be explained in detail by giving examples.

Example 1 The component ratio of α-CD, β-CD and γ-CD is about 6:
A 30% strength aqueous solution was prepared using a 3:1 CD mixture. This aqueous solution contains 67% (f) of the solid content of CD.

11. The clathrate solution was prepared by homogenizing for 5 minutes. Next, this clathrate solution was subjected to spray drying (conditions: population temperature 180°C, outlet temperature 95°C) to obtain a squalane clathrate powder product.

Parts by weight of this squalane clathrate powder, 40 parts by weight of sodium sulfate, 50 parts by weight of sodium bicarbonate, and an appropriate amount of fragrance were uniformly mixed to prepare a powdered bath agent.

Example 2 Using the same CD used in Example 1, an aqueous solution with a concentration of 40% was prepared, squalane in an amount of 70% by weight based on the CD solid content and an appropriate amount of lemon flavor were added, and the mixture was heated at 10,000 r.
p, m,, The inclusion solution was prepared by homogenizing for 10 minutes.

Using this clathrate solution, a liquid type bath agent having the following component ratio was obtained.
