Description

Technical Field [0001] The present invention relates to a sponge for cleaning natural sponge,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a natural sponge for cleaning and a sponge thereof, and more particularly, to a method for producing a natural sponge for cleansing using a dietary fiber, glucomannan and D-glucosamine as main materials, .

In general, cleansing and bathing is the most important basic step in skin care by cleansing the skin by removing waste products, sweat, sebum, dust, cosmetics, etc. to clean the skin including the face.

However, if you apply makeup or UV cream and work hard during the day and do not deep cleanse the skin to the inside of your pores, cosmetics will be mixed with dust, air pollution, sweat, keratin, Or is slowly degraded or oxidized by itself, causing skin irritation, oxidizing skin and forming lipid peroxides, and promoting skin aging. In addition, the aged and clogged pores do not absorb efficiently even if they supply proper nutrition, and even if they provide good and expensive cosmetics and nutrients, they can not deliver the efficacy properly. In some cases, bacteria, bacteria, and fungus can provide a breeding environment, which can cause another skin trouble.

Therefore, in order to enhance the cleaning effect, a cleaning sponge capable of bubbling a rich amount of water without causing skin irritation was developed.

Examples of such a cleaning sponge include synthetic sponge, natural pulp, natural sponge, konjac sponge, and konjac sponge containing a charcoal manufactured through chemical synthesis.

Among these, the synthetic sponge has a bubble but has a stimulus to the skin and is not weakly acidic. In order to prevent bacteria and fungi, a chemical sterilizing component such as tricalcium acid is usually injected, which leads to induction of skin irritation.

Natural pulp is rich in bubbles and is excellent in feeling, but it is not in a weak acid state and induces skin irritation in long-term use. Natural sponges are good in bubbles and feel good, and there is no fear of skin irritation. However, There is a disadvantage that the destruction of the sea ecosystem is concerned.

In addition, the konjac sponge has a bubble soft and soft and has little physical irritation to the skin, but it has a weak alkaline characteristic that stimulates the skin, which has a disadvantage of deteriorating the skin condition. In addition, the konjac sponge containing charcoal also has a disadvantage in that the foam is well and smooth, the physical stimulus to the skin is small, and it is effective in removing wastes, but deteriorates the skin condition due to the weak alkaline characteristic.

These sponges are all products that do not have skin irritation only by using a separate cleaning agent. Skin irritation is induced when only sponge is used without cleansing liquid in finish cleansing. Also, since the removal of waste matter also wipes away wastes through a sponge, There is a disadvantage that it can not be adsorbed.

Therefore, in order to solve these drawbacks, Korean Patent No. 10-1426471 has proposed a natural fiber jelly sponge having a weak acidity. Such a natural dietary fiber jelly sponge is produced through an eco-friendly process, and in order to solve the problem that the sponge becomes alkaline in the conventional manufacturing process, in order to restore the weak acidity characteristic of the dietary fiber, It also has a transparent, moist and soft three-dimensional net structure like jelly that can minimize skin irritation and replenish moisture.

However, the natural dietary fiber jelly sponge also has a disadvantage in that it can not sufficiently remove remaining waste by only using a sponge when the cleaning is finished because the absorbing power of the waste is not strong.

Hereinafter, the present invention will be described in detail.

First, the conventional cleansing sponge was intended to simply expel the foam of the cleansing liquid, and to easily remove the waste matter of the skin through the foam. In other words, during the facial washing using the washing liquid, skin irritation was induced and the sponge could not be used.

Therefore, the present invention uses natural dietary fiber as a raw material so as not to induce skin irritation, adjusts the pH of the sponge to be slightly acidic, and also uses glucosamine having a high waste material adsorption power as its raw material, Of course, by adjusting the pH of the skin to help maintain a healthy skin condition.

The method of manufacturing a sponge according to the present invention comprises the steps of (a) forming an aqueous sol by mixing and stirring glucomannan, purified water, emulsifier and foaming agent, adding a gelling agent and stirring, and (b) (c) adding the solution of the step (b) to the mold, and (d) adding the solution of the step (c) Aging the mold at 20 to 30 ° C for 1 to 24 hours; (e) spongeing the aged material of step (d) by sputtering, cooling, freezing, thawing and washing the same; (D) immersing the sponge of step (e) in organic acid to restore its weakly acidic property; and (g) washing, disinfecting, dehydrating and drying the sponge of step (f).

Hereinafter, the present invention will be described in detail with reference to FIG.

(a) mixing and stirring glucomannan, purified water, emulsifier and foaming agent to form an aqueous sol, and adding a gelling agent and stirring.

First, an aqueous sol is formed using glucomannan, which is a dietary fiber, a gelling agent is added, and the mixture is stirred with a stirrer. The above glucomannan is a natural dietary fiber derived from konjac, which is a substance having a weakly acidic property, and is well known in the field to which this technology belongs, so that a description thereof will be omitted.

At this time, an aqueous sol is formed by mixing purified water, a foaming agent, an emulsifier, a dietary fiber, and a gelling agent together with glucan, which is a dietary fiber. The purified water serves as a medium for solubilizing glucomannan, And the emulsifier is added for smooth mixing of purified water, glucomannan, foaming agent and gelling agent.

After the formation of the aqueous sol, a gelling agent is added and agitated. The gelling agent is for gelling solubilized dietary fiber. The pH of the sol is adjusted to about 9.0 to 12.0 by adding the gelling agent. The gelling agent may be selected from the group consisting of alkali metal hydroxide or carbonate and alkali alkaline earth metal hydroxide or carbonate.

The mixing ratio in step (a) is 5 to 10 parts by weight of a foaming agent, 0.5 to 10 parts by weight of an emulsifier and 0.25 to 10 parts by weight of a gelling agent, based on 100 parts by weight of the glucomannan, Preferably 1,000 to 5,000 parts by weight.

In forming the aqueous sol, gel-forming substances selected from the group consisting of agar, agaroid, agarose, alginic acid, carrageenan, curdlan, gellan, pectin, gel-forming chemical derivatives thereof and mixtures thereof are further included The gel-forming material may be used in an amount of 10 to 200 parts by weight.

(b) adding glucosamine to the solution of the step (a) and stirring the mixture.

Next, glucosamine is added to the solution of the step (a) and stirred. Glucosamine is an acicular crystal obtained from chitin and mucus, and is one of amino sugars which is a combination of an amino acid and a sugar. It is a chitin which constitutes the shell of crustaceans such as shrimp and crab, It is widely distributed as polysaccharide component of sugar. The glucosamine is a component extracted from chitin or chitosan extracted from crustaceans such as crab, shrimp and the like, and when it is used together with natural sponge, it is excellent in removing waste products and heavy metals.

In addition, glucosamine has excellent anti-inflammatory and antioxidant activity, which helps improve skin troubles and maintain skin health.

Such glucosamine may be used in the form of N-acetyl-D-glucosamine in a stable form. The amount of the glucosamine to be used is in the range of 0.1 to 30 parts by weight based on 100 parts by weight of glucomannan, which is used in the step (a) desirable.

(c) injecting the solution of the step (b) into a mold.

Next, the extrusion liquid of the step (b) is injected into a mold to form a shape. At this time, the shape of the mold is not limited, and it is of course possible to form various shapes.

(d) aging the molding die into which the solution of the step (c) has been added at 20 to 30 ° C for 1 to 24 hours.

The molding die into which the above-mentioned solution is injected is aged at 20 to 30 ° C for 1 to 24 hours. This aging step is intended to allow stable gelation of the solubilized dietary fiber.

(e) steam-heating the aged material in step (d) to sponge it, and cooling, freezing, thawing and washing it again.

Then, the aged material is heated in a steam oven at 85-120 ° C for 1 to 5 hours to form a sponge having a three-dimensional net structure through an irreversible heating reaction. At this time, the gelled dietary fiber passes through the bubble generating step, and the bubbles are retained and spongeed after fixing, that is, the tissue is hardened. Here, the sponged dietary fiber is spongeed with glucosamine distributed, that is, the sponged dietary fiber is coupled with glucosamine.

By slowly cooling the sponged dietary fiber, that is, the natural sponge at room temperature for 1 to 5 hours and then freezing it at -30 to -20 ° C for 1 to 5 days, the shape of the sponge and the three- Glucosamine < / RTI > Here, the moisture remaining in the sponge is separated from the net structure by freezing. When the sponge is separated from the net structure and the frozen sponge is thawed in water at 25 to 35 ° C, the net structure is strengthened by discharging the separated water, Purified water, foaming agent, emulsifier, gelling agent and the like are removed.

Next, such a sponge is immersed in clean water, defrosted, and then taken out and dewatered repeatedly to completely remove the additives and various impurities that may remain in the sponge, thereby causing a problem of skin contact with the user's skin It can be prevented.

(f) immersing the sponge of step (e) in organic acid to restore weak acidity.

And the washed sponge is immersed in organic acid for 1 to 24 hours so that the weak acidity characteristic of glucomannan is recovered. That is, as described above, the glucomannan has a slightly acidic property, and the pH is increased by the use of the gelling agent. Therefore, if the gelling agent is thoroughly removed through the washing process and immersed in the organic acid, the characteristic of weak acidity is recovered.

At this time, it is preferable to use at least one organic acid selected from the group consisting of glycolic acid, lactic acid, malic acid, citric acid, mandelic acid, salicylic acid and acetic acid, and 10 to 100 parts by weight of organic acid is mixed with 100 parts by weight of purified water do.

In addition, the pH of the sponge is restored through the use of an organic acid, and the gelling agent remaining in the sponge is completely removed to eliminate the cause of skin troubles.

(g) washing, disinfecting, dehydrating and drying the sponge of step (f).

Next, the sponge having the weakly acidic property is washed, disinfected, dehydrated and dried.

At this time, washing, disinfection, and dehydration of the sponge are well known in the art, and a detailed description thereof will be omitted. The dryer is dried at 35 ~ 55 ℃ for 15 ~ 40 hours to dry the moisture content to 15% or less. Finally, the dried sponge is sealed so that moisture can not penetrate.

The natural sponge produced as described above has a weakly acidic property, which not only protects the skin but also produces a bubble and gives a feeling of soft feeling when using the cleaning liquid. Even when used in a facial cleansing process without using a cleaning liquid, , Keratin and so on by absorbing and eliminating the clear, transparent skin tone will help to maintain.

Hereinafter, the present invention will be described in more detail with reference to specific examples.
