Description

Manufacturing method of soap using persimmon extract {Manufacturing method of soap using a persimmon extract}

The present invention relates to a method for preparing soap using persimmon extract, and more particularly, by preparing soap using immature persimmon extract, a deodorant and microbial proliferation inhibitory effect as well as an excellent whitening effect can be obtained. It relates to a method for producing a soap using.

In general, cosmetic soaps are dissolved by heating and dissolving fatty acids such as Uji and palm oil at 60-70 ℃, followed by saponification reaction by adding alkali salts at 80-90 ℃, and then taking only the upper layer and glycerin and sodium hydroxide. This was removed with concentrated brine, and vacuum dried to obtain a normal soap base having a moisture content of about 13%. The soap base is completed by combining an antioxidant, a color supplement, a perfume, and the like with the soap base.

However, the soap prepared as described above shows alkalinity in aqueous solution as it is prepared by saponification reaction of fatty acid and sodium hydroxide. When frequent washing with such alkaline makeup soap removes sebum components of the skin, water evaporation is excessive. The skin epithelial cells are keratinized so that the skin becomes rough and dry.

In particular, keratinization causes pores to become clogged, so that sebum remains in the pores instead of being discharged to the skin surface. At this time, anaerobic bacteria (for example, propinoibacterium acne , also known as acne bacteria) penetrate and cause inflammation and skin. Make red.

Even if sebum is well discharged from the surface of the skin, it is common that a certain time after washing, the microorganisms in the air multiply on the surface of the epidermal cells, causing the sebum to dissipate and smelling from the skin.

Accordingly, various techniques have been disclosed to suppress odors invented in the skin, and US Pat. No. 4,322,308 discloses 2,4 ', 4-trichloro-2-hydroxydiphenyl ether and 3,4', 4'- A technique of increasing the deodorizing effect by using a mixture of trichloro carbanite and 3-trifluoromethyl-4, 4'-dichlorocarbanilide is disclosed.

However, all of the raw materials used in the technique of US Patent No. 4,322,308 are excellent in deodorizing effect by using chemicals but have the disadvantage of irritating the skin.

Accordingly, the present invention provides a method for preparing a soap using a sensitizer extract which can obtain excellent whitening effect as well as a deodorizing effect and microbial growth inhibitory effect by preparing a soap using a persimmon extract of immature persimmon without using chemicals. The purpose is.

The present invention to achieve the above object

In the method for producing soap by compression molding a soap composition comprising a main ingredient of soap base having a moisture content of 12 to 15% and at least one additive selected from fragrances, colorants, fungicides, anti-inflammatory agents, antioxidants and preservatives,

The soap composition provides 0.2 to 5 parts by weight of the persimmon extract obtained from persimmon per 100 parts by weight of the soap base.

In another aspect, the present invention provides a soap having a deodorizing function characterized in that it is produced by the above production method.

Hereinafter, the present invention will be described in more detail.

In the present invention, in the process of producing a soap using a conventional soap composition containing a soap base as a main component to further include a persimmon extract obtained from persimmon in the soap composition and then to prepare a soap by the conventional method There is a characteristic.

In general, it is known that persimmon extracts obtained from immature (unripe) persimmons not only have an excellent deodorizing function of absorbing and decomposing odors, but also have an antibacterial function of inhibiting the growth of aerobic bacteria by blocking oxygen supply.

Therefore, in view of the action of the persimmon extract of persimmon in the present invention by adding the persimmon extract in the soap manufacturing process it was possible to produce a soap with excellent antibacterial and deodorant effect.

As the persimmon extract, a liquid persimmon extract obtained by pulverizing immature persimmon and then juiced may be used, or a powdery persimmon extract obtained by freeze-drying the liquid persimmon extract may be used.

In addition, the liquid or powdery persimmon extract obtained from the immature persimmon can be added directly in the process of manufacturing soap, but the raw material containing the persimmon extract prepared by a conventional method in the manufacturing process of the soap to prepare a soap You may. As a raw material containing the persimmon extract, a deodorant composition using a deodorant as an active ingredient of the persimmon extract disclosed in Japanese Patent Publication No. Hei 3-61457 or a persimmon extract disclosed in US Pat. No. 6,139,842 is used. Can be used. In addition, FERMON BM-519 (manufactured by Japan SMC) may be used as a raw material containing persimmon extract.

When the raw material containing the persimmon extract is added as described above, the amount of only the persimmon extract is added to 0.2 to 5 parts by weight based on 100 parts by weight of the soap base, as in the case where the liquid or powdery persimmon extract is directly added in the soap manufacturing process. When added, sufficient antibacterial deodorizing effect can be obtained.

At this time, when the amount of the persimmon extract is less than 0.2 part by weight based on 100 parts by weight of the soap base, sufficient deodorization and antimicrobial functions cannot be obtained. Since there is a problem in that discoloration of the skin may inhibit the whitening effect, it is preferable to add 0.2 to 5 parts by weight with respect to 100 parts by weight of the soap base.

In the present invention, a normal soap base is used as a main component together with the extract as an active ingredient. The soap base is dissolved by heating the fatty acid at 60 to 70 ℃, and then subjected to a saponification reaction by adding an alkali salt at 80 to 90 ℃, Take only the upper part and wash it with concentrated brine several times, and then vacuum-dry it to easily obtain the moisture content of about 13%.

In this case, the soap base may be a fatty acid soap base, a synthetic surfactant soap base or a mixture of the fatty acid soap base and the synthetic surfactant soap base.

Fatty acid soap base can be easily obtained through alkali salts and saponification reactions by mixing or mixing animal oils selected from palm oil, palm oil, soybean oil, castor oil, olive oil, palm kernel oil and animal fats selected from tallow, pork and fish oil. have. As the synthetic surfactant soap base, a conventional one selected from sodium lauryl sulfonate, sodium salt of alkylbenzesulfonate, sodium cocoyl isethionate, and alkali metal salt of acyl glutamate can be used. In addition, the fatty acid soap base and the synthetic surfactant soap base may be used in combination.

In addition to the soap base and persimmon extract, the soap composition according to the present invention may be added at least one selected from fragrances, pigments, fungicides, anti-inflammatory agents, antioxidants, preservatives.

In addition, in order to maximize the whitening effect, soap may be prepared by adding herbal ingredients selected from mung bean, licorice, cheonggung, bamboo salt, peppermint, yugeunpi, mancheongcheong, ginkgo, ginseng, leaf, almond.

The soap composition having such a composition can be easily prepared by compression molding in a conventional manner, and in particular, the soap prepared according to the present invention can have a deodorizing and antibacterial effect as well as a whitening effect. have.
