Herbal preservative composition for wet tissue < RTI ID = 0.0 >

The present invention relates to a vegetable preservative composition for a wet tissue, and more particularly, to a vegetable preservative composition for a wet tissue, which comprises a soap nut distiller extract, a whitetoc distiller extract, a noni distiller extract, levulinic acid and hyaluronic acid, And is excellent in safety and further has no risk of discoloring nonwoven fabric or causing stains during the storage period, and a vegetable preservative composition for a wet tissue.

As is well known, a wet tissue refers to a product in which wet tissues impregnated with a liquid preservative are impregnated with a nonwoven fabric made of recycled pulp or blended fibers, and stored in a compact pack. Currently, the commercially available wet tissue products are widely used for infants, ladies, hygiene, medicine, and foodservice industries depending on their use, and their demand is increasing rapidly because they are convenient to carry and easy to use.

The liquid preservative used in the production of wet tissues inhibits the propagation of microorganisms in the nonwoven fabric, prevents the evaporation of water, and helps the cleaning effect. However, since the wet tissue is often used directly in the human body, the preservative should have little skin irritation, have excellent safety, and should have antibacterial activity against pathogenic microorganisms. For this purpose, quaternary ammonium-based cetylpyridinium chloride (CPC) has been widely used as a preservative in the conventional wetting agents for wet tissues. However, the CPC has bubbles, smudged and unpleasant touch over time, And it is reported that there is a problem that diffusion is not performed well.

In addition to the above CPC, chloromethyl isothiazolinone (CMIT), 3-iodo-2-propynyl butylcarbamate (IPBC), polyhexamethylene guanidine (PHMG), benzalkonium chloride, (Edwin et al., Toxicology and Applied Pharmacology, 1998, 153; 12-19), and the possibility of causing skin allergies (Andrea Counti et al., Contact Dermatitis, 1997, 37; 35-36) .

In order to solve these problems, researches on natural preservatives that can satisfy the safety and economical efficiency of wet tissue products have been continued. As a result, there have been developed various kinds of preservatives such as alkaloids, flavonoids, phytoalexins, Herbal medicine extracts containing various natural antimicrobial substances have been proposed.

For example, in Patent No. 10-0770140 (Oct. 18, 2007), inflammation suppression, convergence, irritation inhibition, wound healing, antibacterial and moisturizing effects including a mixed extract of birch sap and rhubarb and swallow swimming And Patent No. 10-1637167 (Jul. 01, 2016) discloses an antimicrobial raw material for a wet tissue including an island giraffe extract, vitamin B1 lauryl sulfate, sorbic acid and yucca extract, , And Patent No. 10-1533195 (Jun. 25, 2015), a wet tissue composition using a natural preservative, which includes a roots extract, citrus extract and pine leaf extract, is introduced.

The above vegetable preservatives have the advantages of less side effects on human skin and superior safety than conventional chemical preservatives. However, due to the nature of herbal medicine extracts, even if they are filtered, suspended and fine suspended particles remain, There is a problem that the color of the nonwoven fabric is changed or unevenness occurs.

Hereinafter, the present invention will be described in detail. However, even if it is indispensable to carry out the present invention, detailed description of the matters which belong to the known technology or can be easily carried out from the prior art will be omitted.

In the present invention, the term 'distillation extract' refers to a method in which a substance to be extracted containing an active ingredient is put into purified water and heated, and the volatile active ingredients are evaporated and evaporated. When the volatile active ingredients are collected and cooled again, Is obtained, which is referred to as distillation extract. Also, the term 'concentrated extract' means a viscous liquid substance obtained by putting a plant material containing an active ingredient into purified water and heating and concentrating it continuously.

The vegetable preservative composition for a wet tissue according to the present invention comprises a soap nut distillate extract, a whitecross distiller extract, a noni distiller extract, levulinic acid and hyaluronic acid.

First, the sofnut distillate was pulverized soapnut, that is, soapberry shells and purified water were put into an extractor at a weight ratio of 1: 1, heated at 60 ° C for 15 hours, Is a clear and transparent liquid which is evaporated again for 8 ~ 10 hours and collected vaporized volatile active substances again and liquefied.

As a reference, an unaffected tree is a broad-leaved arboreous tree distributed in Korea, Japan, and China. It forms a round-shaped nucleus and fruit with a brown color in September-October. Therefore, the sofunut extract is also referred to as a patient-free extract, and contains a large amount of saponin as a main component of ginseng, and has excellent antibacterial activity and cleansing power, so that the soap-concentrated extract has been conventionally diluted and used as a soap, a cleanser and a cosmetic raw material.

In the vegetable preservative composition for wet tissues according to the present invention, the content of the above-mentioned soybean distillate distillate is 100 parts by weight as a standard content.

Meanwhile, according to one embodiment of the present invention, the softened distillation extract may contain 5 to 10 parts by weight of a concentrated softened extract, relative to 100 parts by weight of the softened distilled extract. The concentrated softened extract has a function of raising the viscosity of the softened distilled extract as a liquid concentrate having a high viscosity, which is obtained by preparing the softened distilled extract.

In the present invention, when the content of the concentrated softened extract is less than 5 parts by weight, there is a problem that the viscosity of the softened distilled extract is low and the softened distilled extract tends to be sprung during handling. On the other hand, The viscosity is too high and the color may be deteriorated.

Next, the Houttuynia cordata distillation extract was prepared by pulverizing Houttuynia cordata crusher and pulverizing it with purified water in an extractor at a weight ratio of 1: 1, heating it at 60 DEG C for 15 hours, distilling it at 80 DEG C for 8 to 10 hours It is a clear and transparent liquid which collects vaporized volatile active substances and liquefies again.

Hwasungcho is a year-old seedling of Saururus chinensis, also known as an eggplant, which grows well in the shaded forests. The stem is straight and grows about 20 ~ 50cm in height and has several vertical lines. Leaves are alternate phyllotaxis, 3 ~ 8cm long, pointed end, plain edge, stipule attached to bottom of petiole.

In the private sector, it is used as a diuretic or insecticide before flowers are bloomed. It is used when it is applied to boils or insect pests, or used for boils, pesticides, and hemorrhoids. In one room, plants are treated for gonorrhea, enteritis, urinary tract infections, It is also used for bronchitis. It is named after the name of the sea urchin because it is fishy on the leaf.

Also, it is known that Hwasungcho extract is effective in blood circulation by bathing in bath water, has effect to improve atopy, clears blood to clear blood, and has excellent sterilization effect. So, conventionally, we have been using watercress products in bath products, detergents, hair products and so on.

In the preservative composition of the present invention, it is preferable that the content of the Holstein leaf extract is in the range of 45 to 60 parts by weight based on 100 parts by weight of the SOFTNUT distillation extract. If the content of the olive oil distillation extract is less than 45 parts by weight, the effect of the active ingredients contained in the olive oil extract is insignificant, and if the content is more than 60 parts by weight, it is not preferable.

Next, the noni distillate extract was pulverized and pulverized with purified water in an extractor at a weight ratio of 1: 1, heated at 60 ° C for 15 hours, distilled at 80 ° C for 8 to 10 hours, It is a clear and transparent liquid which collects volatile active substances and liquefies again.

Noni is a dicotyledonous plant that grows in volcanic soils, and is introduced as a sea bream or sea bream in Dongbokgam. It is a tropical plant that grows mainly in the South Pacific such as Guam, Hawaii, Fiji, New Zealand, etc. It grows about 3 ~ 12m in size and its fruit size is about 10cm and it is similar to uneven potato shape. Unlike other plants, noni is characterized by first blooming fruit and flowers.

Aboriginal peoples of the South Pacific have used the noni for a very long time in traditional ways in many areas of everyday life, especially in Hawaii and Tahiti, where they have considered this plant as a panacea. Recently, it has been known that noni fruit increases immunity, fatigue and restorative recovery, various adult diseases and skin health of women have been developed and used variously as health food raw materials.

In the present invention, it is preferable that the content of the noni distillate extract is 3 to 7 parts by weight based on 100 parts by weight of the extracted soft nanolin. If the content of the noni distillation extract is less than 3 parts by weight, the effect of the active ingredients contained in the noni extract may be insufficient, and if it is more than 7 parts by weight, skin troubles may occur I do not.

Next, levulic acid, also referred to as? -Acetyl propionic acid, is a colorless plate-like or leaf-like crystal that easily dissolves in water, ethanol and ether, and does not dissolve in aliphatic hydrocarbons and the like. The heat is fairly stable, but when heated for a long time, it is condensed in the molecule to become unsaturated lactone.

The levulinic acid has a function of controlling the acidity of the preservative composition according to the present invention together with the preservative function, and it preferably contains 20 to 30 parts by weight based on 100 parts by weight of the extracted soy nodule. If the content of levulinic acid is less than 20 parts by weight, the preservative effect is reduced. On the other hand, if the content exceeds 30 parts by weight, skin irritation increases.

Finally, the hyaluronic acid is one of complex polysaccharides composed of amino acid and uronic acid, and is a high molecular compound composed of N-acetylglucosamine and glucuronic acid. It is abundant in the vitreous body and umbilical cord of the eye in the human body and functions to prevent infiltration of bacteria and penetration of toxic substances. In addition, it has a high viscosity and has a property of binding with a large amount of water to form a gel, thereby improving the lubricating action of the joint and improving the flexibility to the skin.

In the present invention, the hyaluronic acid acts to prevent penetration of germs or toxic substances into the skin and to enhance the skin moisturizing function, and it is preferable that 10 to 15 parts by weight of the hyaluronic acid is included in 100 parts by weight of the extract Do.

If the content of the hyaluronic acid is less than 10 parts by weight, the effect of hyaluronic acid can not be expected. Conversely, if it exceeds 15 parts by weight, skin troubles such as itching, red spot, and urticaria may occur.

The method for producing a vegetable preservative composition for wet tissues according to the present invention is characterized in that 45 to 60 parts by weight of a perch syrup extract and 3 to 7 parts by weight of a noni distillate extract are mixed with 100 parts by weight of a softernut distillation extract, Allow to slowly cool naturally while stirring at a temperature for 5 hours. If the agitation temperature is less than 70 ° C, mixing may not be successful. On the other hand, if the agitation temperature is 85 ° C or higher, browning may occur. At this time, the softened distillation extract may contain 5 to 10 parts by weight of a concentrated softened extract, based on 100 parts by weight of the softened distilled extract.

Next, the mixture is cooled to 30 to 35 DEG C, and 20 to 30 parts by weight of levulinic acid and 10 to 15 parts by weight of hyaluronic acid are mixed with 100 parts by weight of the above-mentioned softened distillate extract, and then mixed well. Since levulinic acid and hyaluronic acid are weak to heat and volatile, they are mixed at a relatively lower temperature than the distillation column. The preservative composition for a wet tissue of the present invention thus produced preferably has a specific gravity of 0.95 to 0.97 and a pH of 2.5 to 5.5.

When preparing the wet tissue using the above-mentioned preservative composition, purified water is added to the above preservative composition to dilute the concentrate to a concentration of 0.05 to 0.4 Vol%, and then the weight ratio of the preservative composition: nonwoven fabric diluted to a conventional nonwoven fabric for wet tissue production is 1: 3 < / RTI >
