JPH0482816A - Scrubbing face washing material - Google Patents

Abstract

PURPOSE:To obtain a scrubbing face washing material having antimicrobial action and beautifying action besides physically removing stain, blended with small pieces of dried bark of Magnolia obovata. CONSTITUTION:A scrubbing face washing material blended with small pieces (properly about 0.1-1mm) of dried bark of Magnolia obovata of the genus Magnolia of the family Magnoliaceae. Magnolia obovata has optimum hardness as a scrubbing material, naturally shows characteristic scrubbing effects and has mildly sterilizing action and beautifying action. When a cosmetic blended with magnolol, honokiol and an extract of Magnolia obovata with an organic solvent is used after face washing with the face washing material, the effects are enlarged and the cosmetic is applied not only for pimple but also for a wider use.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facial scrub that not only physically removes dirt but also has antibacterial and whitening effects.

[Conventional technology]

The raw materials commonly used as scrubbing agents are silica beads,
Cellulose beads, anse endocarp, almond fruit,
Polyethylene powder etc. are used. However, all of them only physically remove dirt and have almost no other effect.

Japanese Patent Publication No. 1-48488 describes a pH buffering effect using conchiolin powder, but that is all there is to it.

On the other hand, Atsuboku is the dried bark of the magnolia tree, which belongs to the Magnoliaceae family. This Koboku is a medicinal herbal medicine listed in the pharmacopoeia that has sedative, muscle relaxant, anticonvulsant, and spinal reflex suppressive effects, and in particular, the active ingredients contained in it, magnolol and hoonokiol, are reported to have central muscle relaxant effects. It is used for medical conditions such as back pain and colds.

However, there is no record of its use as a cosmetic.

[Problem to be solved by the invention]

In addition to physically removing dirt, scrubbing agents have the following effects:
Naturally, it is more desirable for cosmetics to have necessary effects.

The first objective of the present invention is to provide a facial scrub that not only physically removes dirt but also has antibacterial and whitening effects, and which is safe for long-term use on the skin.

[Means to solve the problem]

As a result of studying various plants that have been used since ancient times, the present inventors found that magnolol and honokiol contained in the bark of the magnolia tree have the effect of inhibiting acne-related bacteria.

Furthermore, it was found that magnolol and honokiol, which are contained in the bark of the magnolia tree, inhibit tyrosinase activity.

Therefore, there is a way to simply use this as a cosmetic.
It was discovered that it can be used as a scrubbing agent by taking advantage of its shape.

In other words, the present invention is a facial scrub that contains thin pieces of Japanese turmeric.

The dried bark of the Japanese magnolia tree is used as a scrubbing agent by cutting it into pieces of an appropriate size, for example, 0.1 to 1 mm, but it can also be used as a scrubbing agent by first grinding it into a fine powder and then cutting it to the required size with resin, etc. good.

Koboku has the optimum hardness for use as a scrub agent, and not only does it have the original scrubbing effect, but it also has mild bactericidal and whitening effects.

In addition, after washing your face with a facial scrub, apply one of the extracts of Magnolol, Hoonokiol, Koboku using at least one solvent such as methanol, ethanol, acetone, and ether.
By using cosmetics that contain at least one of these seeds, the effect will be greater and it can be used not only for acne but also for a wide range of other purposes.

For reference, the antibacterial properties of Magnolol and Hoonokiol are as follows;
．． 0% by weight, and 0.1 to 1.0% by weight of honokiol.

The structure of magnolol and honokiol is CH2= CH
CH2CH2CH= CH2 For magnolol and honokiol, the minimum inhibitory concentration (MIC) (
ppm) was measured.

A liquid culture method was used, and if the specimen was in a dispersed state, shaking was added during culture. The results are shown in Table 1.

Shows excellent antibacterial properties against hair follicular bacteria, Staphylococcus aureus, and Propylonibacterium acnes.

Table 1 Also, the inhibition of tyrosinase activity by magnolol and honokiol [Test method] Mc11valne buffer 09ml 1.1.86mM T
1.0 ml of the yrosine solution and 1.0 ml of the sample solution were placed in a screw vial and heated in a constant temperature water bath at 37° C. for 5 minutes or more. Tyrosinase solution (manufactured by Sigma, derived from pine mushroom, 914 units/rnl) 0.
1 ml was added, kept warm in a constant temperature water bath at 37°C, and absorbance was measured at 475 nm after 10 minutes. In addition, as a control, pure water was added instead of the above sample solution and measurements were made in the same manner.

[Trial calculation formula]

Tyros+nase activity inhibition rate (%) = fB-(A
