Description

Sheet-shaped water-soluble solid clarifying foam with maltitol applied and its manufacturing method { Sheet-shaped water-soluble solid clarifying foam with maltitol and its manufacturing method }

The present invention relates to a cleansing foam, in particular, by applying maltitol, a water-soluble polymer material having high water absorption and high stability at room temperature, to a liquid cleansing foam composed of a moisturizing agent and a surfactant to solidify it, process it into a film form, and cut it It relates to a sheet-shaped water-soluble solid cleansing foam to which maltitol is applied and manufactured in a sheet form and a method for manufacturing the same.

In general, in order to protect the skin, it is necessary to clean the face after using cosmetics (especially color cosmetics) so that residues of cosmetics do not remain on the face. The cleansing operation is performed by dissolving cosmetic ingredients with a cleansing cream or liquid cleansing foam contained in a tube.

However, since the container used for the cranling cream or cranzing foam is sold in a large capacity, it cannot be carried, and it is cumbersome to carry it in subdivisions.

A general creasing cream or cranzing foam is a liquid product by mixing a surfactant including fatty acid soap for foaming and detergency, oil and a moisturizer, and is sold in cream type lotion type, aerosol type, etc. Due to the characteristics of the easily evaporated cranzing cream or cranzing foam, if the cap is not tightly sealed after use, the risk of deterioration is very high. it was necessary

In order to solve this problem, Patent Laid-Open No. 10-00005335 (hereinafter referred to as 'prior art 1') has proposed a cosmetic cleansing foam processed in the form of a water-soluble film including xanthan gum or guar gum.

However, Xanthan Gum or Guar Gum used in Prior Art 1 above is a kind of food additive, and has the characteristics of increasing adhesion and viscosity and enhancing emulsion stability, but acidic or alkaline substances coexist. There is a problem in that the viscosity is lowered.

In addition, in Patent Registration No. 10-1964666 (hereinafter referred to as 'prior art 2'), a solid water-soluble foam cleansing was prepared using corn starch as a pad tissue former.

However, the water-soluble solid foam cleansing using corn starch of the above prior art 2 consumes a lot of water vapor and moisture in the air due to the characteristics of corn starch, and the solid foam cleansing becomes soggy, and after a period of time, it contains a lot of moisture, so it can be used as a product. value goes down As it contains a lot of moisture, the foaming power of the solid foam cleansing is also reduced, so the physical properties of the product cannot be maintained uniformly for a long time.

Moreover, the corn starch used in the prior art 2 contains a lot of moisture, so there is a problem in that the shape cannot be maintained during molding.

The present invention is to solve the above problems, by applying maltitol, a water-soluble polymer material having high moisture absorption and high stability at room temperature, to a liquid cleansing foam composed of a moisturizing agent and a surfactant, and solidifying it in a film form. An object of the present invention is to provide a water-soluble solid cleansing foam that is cut after processing and manufactured in a sheet form, which greatly improves storage and portability.

As the moisture of the solution evaporates, it is processed and cut into a sheet form with a moisture content of 10% or less, and the maltitol is 15 to 30% by weight based on the total weight of the solid cransing foam, and the polyvinyl alcohol is the solid cranzing foam. It is characterized in that it consists of 30 to 55% by weight based on the total weight.

In addition, the method for producing a sheet-shaped water-soluble solid cranling foam to which maltitol according to the present invention is applied includes a mixed solution preparation step (S10) of mixing a plurality of components, a sheet forming step of casting to solidify into a sheet shape (S20), certain In the manufacturing method of the cranzing foam in which the drying step (S30) of drying the sheet to the following moisture content is sequentially performed, in the mixed solution preparation step (S10), purified water as a solvent; A solidifying agent for maintaining the shape of the solid state; Moisturizers including dipropylene glycol and butylene glycol; And a surfactant as a detergent is mixed to form a mixed solution with a moisture content of 70% or more, and in the drying step (S30), the molded sheet is dried by hot air at a temperature within 120 to 150 ° C. The weight of water is adjusted to within 10% of the moisture content, water-soluble polyvinyl alcohol (PVA) is 30 to 55% by weight based on the total weight of the solid cleansing foam, and maltitol is 15 to 30% by weight based on the total weight of the mixed solution It is characterized by its technical characteristics.

The sheet-shaped water-soluble solid cranling foam to which maltitol according to the present invention is applied can be molded in any shape in a solid state by applying maltitol, which has excellent shape retention, so it can be custom-made in various shapes according to the customer's request. The process is easy, so the production cost can be reduced, and the convenience of use is greatly improved because it is easy to carry by maintaining the solid shape.

In addition, since maltitol with excellent storability is applied, the consistency of quality is maintained even when stored for a long period of time, thereby increasing the shelf life.

1 is a configuration diagram schematically showing a method of manufacturing a sheet-shaped water-soluble solid cranling foam to which maltitol according to the present invention is applied.

A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The present invention includes purified water, a moisturizer, and a surfactant, which are components of a general cleansing foam, and has its technical features by adding a specific solid component to transform the cleansing foam into a solid state.

In one embodiment of the present invention, the sheet-shaped water-soluble solid cleansing foam to which maltitol is applied according to the present invention includes purified water as a solvent; A solidifying agent for maintaining the shape of the solid state; Moisturizers including dipropylene glycol and butylene glycol; And a surfactant as a detergent is mixed to form a mixed solution having a moisture content of 70% or more, and the mixed solution is cast and dried to be processed and cut into a film form to prepare a sheet form.

In particular, the solidifying agent is characterized in that it is composed of maltitol, a sugar alcohol, and polyvinyl alcohol (PVA), a water-soluble polymer.

In the present invention, the unique properties of maltitol are utilized to compensate for the problems of xanthan gum, guar gum, and corn starch used in the prior art.

은 글루코오스가 a-1, 4 결합한 환원성 이당류인 말티오스에 수소를 첨가하여 얻은 디사카라이드폴리올이고, 알데히드기를 포함하지 않기 때문에 아미노산, 단백질과 공존하더라도 아미노카르보닐반응(메이라드반응)을 일으키지 않는 성분이다. maltitol

Silver is a disaccharide polyol obtained by adding hydrogen to maltose, a reducing disaccharide in which glucose is bound to a-1, 4, and does not cause an aminocarbonyl reaction (Meirard reaction) even when coexisting with amino acids and proteins because it does not contain an aldehyde group. is an ingredient

In particular, the maltitol applied to the solid foam of the present invention does not change the physical properties of the solid foam cleansing even after a long period of time, and can maintain uniform physical properties for a long time without moisture. In addition, due to the characteristics of maltitol, a sugar alcohol, it forms a moisture barrier on the skin, which is superior to solid foam cleansing using corn starch, and gives more gloss and moisture to the skin after washing.

The solid cleansing foam containing maltitol, a sugar alcohol, has the advantage that it can be molded into any shape because its shape is well maintained.

Maltitol is a disaccharide alcohol composed of glucose and sorbitol. It is an artificial product obtained by hydrogenating maltose. It has properties such as heat resistance, acid resistance and alkali resistance, so it is very stable to changes in pH and temperature, and there is no browning reaction due to heating.

In particular, since it is difficult to metabolize by microorganisms, the use of maltitol in food processing and solid cleansing foam formation can improve preservation.

Furthermore, maltitol in the cosmetic industry is an ingredient that can be used as a moisturizer together with xylitol, and has the characteristics of a moisturizer that is less susceptible to changes in humidity in the air. to prevent dryness and keep the skin moist.

That is, a feature of the present invention that is differentiated from the prior art is that water-soluble maltitol is added to polyvinyl alcohol, which is a basic component, and used as a solidifying agent in order to prepare a water-soluble cleansing foam having a solid sheet shape.

Maltitol applied to the present invention is used as a moisturizer, and moisture does not evaporate well in a dry place, and hardly absorbs moisture in a humid place.

Therefore, compared to conventional corn starch, which has a high moisture content and is difficult to maintain a solid shape, maltitol of the present invention absorbs purified water in the aqueous phase to evaporate moisture and form a more firmly coated water-soluble solid sheet cleansing foam. Therefore, there is a significant increase in the effect in the manufacturing step.

Moreover, US GMO corn, which is generally the main raw material for corn starch, is a genetically engineered plant material in which insecticidal toxin protein genes are injected. Even when converted to syrup, most remain. (Reference: Report on Modified Starch Industry)

Since these toxin proteins have a fatal problem that causes hives or atopy on the skin, the applicant of the present application tested various ingredients for a long time to replace corn starch, which is the main ingredient of solid cleansing foam that directly touches the skin. Maltitol is applied as a component of

As an embodiment of the present invention, the content of polyvinyl alcohol relative to the total weight of the solid cranzing foam is 30 to 55 wt%, and the content of maltitol is 15 to 30 wt%.

On the other hand, the polyvinyl alcohol (PolyVinyl Alcohol; PVA) is obtained by hydrolyzing polyvinyl acetate and is a water-soluble white solid that is a linear polymer of vinyl alcohol (CH2=CHOH). In the present invention, the number average degree of polymerization is 200 to 1500 and saponification Low molecular weight polyvinyl alcohol having a molecular parameter of 82 to 92% is used as a component of the solidifying agent together with maltitol.

In general, the average degree of polymerization refers to the average degree of polymerization of mixtures with different degrees of polymerization. Mainly, polymer materials are mixtures with different molecular weights, so the size of the molecule is determined by the number of repetitions (degree of polymerization) of a certain structure instead of the molecular weight. will show In addition, the degree of saponification refers to the amount of potassium hydroxide required to saponify 1 g of fat as the saponification value, and the degree of saponification varies depending on the purity of the component.

In addition, the surfactant applied to the present invention may contain anionic, nonionic, and amphoteric surfactants, and is a naturally derived surfactant instead of a sulfate-based surfactant that can irritate the skin. The surfactant is preferably included, and the content of the surfactant is 20 to 40% by weight based on the total weight of the mixed solution.

In addition, the moisturizer applied to the present invention includes any one or more of dipropylene glycol, butylene glycol, and propylene glycol, and the content of the moisturizer is 3 to 8% by weight based on the total weight of the mixed solution.

In addition, as other additives 1, one or more from the group consisting of a stabilizer, a pH adjuster, a chelating agent, a fragrance, a preservative, a pigment, a skin protectant, an emollient, a plant extract, etc. can be included within 2% by weight of the total weight of the mixed solution have.

In addition, as other additives 2, centella asiatica extract, propolis, tea tree, cypress oil, astaxanthin, resveratrol, ascorbic acid, etc. are used as skin conditioning agents, skin protectants, skin antibacterial agents, and antioxidants by 1 weight based on the total weight of the mixed solution. % can be included.

Hereinafter, as shown in FIG. 1, the manufacturing method of the sheet-shaped water-soluble solid cranling foam to which maltitol is applied according to the present invention includes a mixed solution preparation step (S10), a sheet forming step (S20), and a drying step (S30). proceeds

Second, in the sheet forming step (S20), the mixed solution is cast to form a sheet shape.

The casting refers to an operation of pouring a fluid substance such as a molten material and an abnormal substance into a mold, and a fluid mixed solution is put into the mold and solid by a separate curing agent. to harden the state.

As the formwork, hard materials such as metal, glass, gypsum, and wood, those made of soft elastic materials such as agar, gelatin, and soft vinyl chloride, and intermediate materials such as wax or thermoplastic plastic sheets can also be used.

Third, in the drying step (S30), the molded sheet is dried and the moisture content is adjusted to less than 10%.

It is dried in the drying step (S30) to adjust the moisture content to 10%, and the content of maltitol is very important in order to maintain the quality of the product. At this time, in the drying step (S30), it is preferable to perform the hot air drying at a temperature within 120 ~ 150 ℃.

That is, if the content of maltitol is too much or too little, sheet formation may not be possible. Therefore, it is preferable that maltitol in the present invention is comprised of 15 to 30% by weight based on the total weight of the solid cransing foam.

In particular, since the protein component contained in the corn starch of Prior Art 2 is denatured at 60 to 70° C., it is impossible to dry it with hot air in a short time.
