Description

Composition of wash-off pack with natural substance, and its manufacturing method

The present invention relates to a wash-off pack that is applied to the face, etc., and washed and removed after a certain period of time. In particular, the wash-off pack replaces microplastics, which are environmental pollutants, by adding pear cells as a natural component to the wash-off pack. The present invention relates to a wash-off pack composition containing natural ingredients and a method for manufacturing the same, by adding chitosan to improve a cleansing function having antibacterial and moisturizing properties.

In general, the wash-off pack is one of the packs that is applied to the face and nourishes tired skin by removing it through face wash after a certain period of time has passed, and this wash-off pack has very little irritation to the skin and is easy to use. It has been popularized because it is known to have excellent functions of removing impurities from pores and exfoliating skin.

In particular, the wash-off pack provides moderate tension on the skin surface as the pack agent hardens, thereby promoting blood circulation due to an increase in skin temperature, blocking external air, facilitating absorption of nutrients, and helping to supply moisture. It adsorbs contaminants or keratinocytes on its surface and keeps the skin moist.

However, microbeads, called microbeads, are contained in cosmetics, toothpaste, detergents, scrubs, etc., which are easily accessible in everyday life, and because the particles are small, they are not filtered by sewage purification facilities and microplastics introduced into the sea You can return to a person through the food chain.

In particular, according to a report by the European Commission on Environment and Enforcement, the fine plastics contained in cosmetics are introduced into the sea around Europe up to 8627 tons per year, and thus microplastics can be transferred to and accumulated in various individuals. Fine plastics are still being added during the manufacture of off-packs.

Moreover, there are regulations on micro plastics around the world, and in Korea, some amendments to the "Cosmetics Safety Standards" have been prepared, and since 2017, the use of micro plastics in cosmetics has been banned. Research on the wash-off pack is urgent.

In addition, the cosmetics and household goods industry, which recognized the problem of the fine plastic, recognizes the necessity of converting the substitute, but still has not found a complete substitute, and even if there are eco-friendly materials that can replace the fine plastic, the cost of the plastic is a natural material. It is cheaper, so it is difficult to replace.

Therefore, research to maximize the efficiency of nutrient supply as well as to minimize the occurrence of environmental pollutants by manufacturing wash-off packs that do not contain microplastics in order to relieve the anxiety of the general public as well as the chemicals.

Hereinafter, an embodiment according to the present invention will be described.

1 to 3,

Wash-off pack composition according to the present invention, at least selected from the group consisting of cosmetic ingredients to provide various nutrients, including water necessary for moisturizing the skin, and surfactants, exfoliants and antibacterial agents mixed with the cosmetic ingredients to provide functionality As a wash-off pack composition containing a natural component comprising at least one,

The cosmetic ingredient is at least one selected from oil stabilizers, moisturizers, preservatives, clays, and thickeners, the surfactant is at least one selected from water-soluble surfactants, oil-based surfactants, and the exfoliant is a stone cell of the stomach. And, the antibacterial agent is characterized in that the chitosan of crustaceans.

First, in constructing the wash-off pack composition according to the present invention, in order to increase the wash-off power or cleansing power to the cosmetic ingredient, as well as to reduce the occurrence of environmental pollutants, it is used in the formulation of the cosmetic ingredient. In addition to the surfactant, it is characterized by adding an exfoliating agent of natural ingredients and an antibacterial agent of natural ingredients.

In particular, the wash-off pack composition according to the present invention can be used for the whole body including the face, neck, shoulders, arms, and legs of a consumer. It has a feature that exfoliation and antibacterial properties are increased by chitosan of the pear stone cells and the crustaceans.

In addition, the cosmetic ingredients provide various nutrients to the body of the consumer, and solid or liquid ingredients can be used alone or in combination, and the cosmetic ingredients include oil stabilizers, moisturizers, preservatives, clays, and thickeners. Either one or a mixture thereof is preferred.

The solid phase component means a component that maintains a solid state at room temperature but melts and liquefies at a temperature of about 30 ° C. or higher, from a group consisting of 1,2-pentanediol, trehalose, glycerin, methyl paraben, kaolin, bentonite, and polyacrylamide. It is preferable that at least one selected is selected, but is not limited thereto.

The liquid phase component is preferably at least one selected from the group consisting of cetyl alcohol and jojoba oil that maintains a liquid state at room temperature, but is not limited thereto.

The cosmetic ingredient is preferably contained in 38 to 42 parts by weight based on 100 parts by weight of the total composition, but is not limited thereto, and in particular, the cosmetic ingredient is included in the technical category of the present application without adding the thickener.

When the cosmetic ingredient is less than 38 parts by weight, it is difficult to smoothly supply nutrients to the skin. When the cosmetic ingredient exceeds 42 parts by weight, the formulation stability of the pal deteriorates and the usability decreases, thereby limiting its content.

In addition, the surfactant is a generic term for a surfactant having both cationic and anionic groups in the same molecule, and the surfactant is preferred to select a material having excellent cleaning power and less skin irritation, especially water-soluble surfactant and oil phase. Any one of surfactants or mixtures thereof is preferred.

The water-soluble surfactant is preferably cocamidopropyl betaine or potassium cocoyl glycinate, and the oil-based surfactant is preferably selected from the group consisting of sorbitan monostearate and polysorbate 60, but other known Even the use of surfactants is included in the technical category of the present application.

It is preferable that the surfactant contains 28 to 32 parts by weight based on 100 parts by weight of the total composition, and when the surfactant is less than 28 parts by weight, the cleansing effect is relatively reduced, and when the surfactant exceeds 32 parts by weight, the skin It caused irritation and the formulation stability was lowered, so its content was limited.

And, the stone cells are present in the rind and pulp of the embryo (fruit), called reinforcing cells or posterior wall cells, and the cell wall is hardened as a kind of lignification in which lignin is deposited on the cell wall in the tissue of the embryo. It strengthens the cells and serves as a frame for fixing the shape of the cell wall so that it does not change.

Table 1 is a composition of the components of the stone cells, and the stone cells had the most lignin, followed by the content of cellulose and hemicellulose. The main component of the stone cells is lignocellulose and contains about 18 to 35% of lignin that is not in the primary cell wall.

Cellulose 30.0 Lignin 32.3 Hemicellulose 22.7 Pectin 5.2 Others 9.8

The distribution of the stone cells can be easily confirmed by a phloroglucinol staining method, and the lignin is stained in red orange. The stone cells are surrounded by pulp cells, and the stone cells at this time cannot be used as an abrasive. Since the surrounding flesh cells must be removed, it can be used as an abrasive, so it is extracted and used by physical and chemical methods.

Further, the chitosan is a natural animal marine polymer, and can be obtained by deacetylation of chitin contained in shells of crustaceans such as crab and shrimp, and has a similar chemical structure to the cellulose.

The chitosan is a kind of cationic basic polysaccharide, which has properties of biodegradability, bioactivity, and biocompatibility to alleviate wound pain and facilitate adhesion to promote skin regeneration, and the causative agent of skin disease inhibits the growth of Trichophyton equinum, , It has antibacterial and moisturizing properties, and plays a role in helping cell proliferation and differentiation.

The chitosan is more effective against Gram-positive bacteria than Gram-negative bacteria and shows relatively weak antibacterial activity against fungi.

The chitosan is known as an alternative material capable of supplementing the functions of the biological components, glycoprotein, mucopolysaccharide, collagen, and elastin after being used as a moisturizer in the cosmetic field among natural polymers because of its excellent removal effect and physical properties in the body. It functions as a nutrient supply for skin and as an anti-aging substance.

[Stone cell extraction method]

First, in extracting the stone cells of the pear, after washing the pear to finely grind to a certain size to prepare a pulverized product, the water contained in the crushed product is decompressed with a vacuum filter and the thermostat is operated to remove the moisture. It was removed to the maximum. At this time, the total weight of the pulverized product was measured to be 66.2 g.

Subsequently, 252 ml of 99.5% ethanol was quantified in order to mix the pulverized product and ethanol in a 1: 3 weight ratio. In order to homogenize the mixture of the pulverized product and the ethanol, the sugar component was removed by filtering under reduced pressure using a filter paper. At this time, the weight of the solid content remaining on the filter paper after the vacuum filtration was measured 54.45g.

Subsequently, the unfiltered solid content and strong acid remaining on the filter paper were mixed at a weight ratio of 1: 5, stirred for one hour, filtered under reduced pressure to remove remaining sugar components, and a 20% aqueous sulfuric acid solution was used as the strong acid.

At this time, 319 ml of the sulfuric acid aqueous solution was used, and this is to quantify the solid content and a 1: 5 mass ratio. The solid solution and the sulfuric acid aqueous solution were shaken with stirring for one hour, and the shaken water was filtered under reduced pressure to remove the remaining sugar component. The weight of solids remaining on the filter paper was 111.87 g.

Subsequently, the unfiltered solids and strong base remaining on the filter paper were mixed at a weight ratio of 1: 3, stirred for one hour, and filtered under reduced pressure to remove proteins. At this time, a 10% aqueous sodium hydroxide solution was used as the strong base.

Subsequently, 336 ml of the sodium hydroxide aqueous solution was used, and this is for quantifying a solid content and a 1: 3 mass ratio. The solid and aqueous sodium hydroxide solution were shaken with stirring for one hour, and the shaken water was filtered under reduced pressure to remove protein. At this time, the weight of solids remaining on the filter paper was measured to be 42.31g.

Subsequently, it was considered that purification of the obtained solid content was necessary, it was put into purified water and stirred for primary purification. Then, the purified solid content was stirred in ethanol, and filtered under reduced pressure for the stirred solution. At this time, the weight of the solid content remaining on the filter paper was measured 36.37g.

Subsequently, the solid content was dried in a thermostat at 60 ° C. After drying, the solid content was agglomerated and did not have a uniform size and was non-uniform.

The aggregated and non-uniform solid content was crushed into a uniform and small size using a pestle bowl so as to have a size suitable for the wash-off pack composition to prepare stony cells of the size required for the present invention.

[Method of manufacturing wash-off pack]

The method for preparing the wash-off pack composition according to the present invention is a first step of sequentially adding water, trehalose, glycerin, 1,2-pentanediol, methylparaben, and seok cells and warmly dissolving them at 65 to 75 ° C to mix them. Wow; A second step of sequentially adding chitosan, potassium cocoylglycinate, and cocamidopropyl betaine to the mixture of the first step and stirring and dispersing it at 65 to 75 ° C; A third step of sequentially adding kaolin and bentonite to the mixture of the second step and stirring and dispersing it at 38 to 42 ° C; A fourth step of sequentially adding cetyl alcohol, polysorbate 60, sorbitan monostearate, and jojoba oil and heating to 65-75 ° C. to dissolve; And a fifth step of adding the mixture prepared in the fourth step to the mixture prepared in the third step and stirring to prepare a pack composition.

As shown in Table 2, in the present invention, a wash-off pack having a composition ratio as in Samples 1 to 5 was prepared, and the method of manufacturing the Samples 1 to 5 can be summarized as follows.

(1) first step; Water, Trehalose, Glycerine, 1,2-pentanediol, methyl paraben, and stone cells in a temperature range of 65 to 75 ℃ Dissolved by heating and stirred uniformly.

The temperature range in the first step is preferably about 70 ° C, but since the materials for the first step are various types, the melting temperature is limited to 65 to 75 ° C.

(2) second step; Chitosan, Potassium Cocoyl Glycinate, and Cocamidopropyl Betaine were sequentially added to the first step and sufficiently dispersed using a stirrer.

The chitosan (Chitosan) was dissolved in 0.1% acetic acid aqueous solution and added.

(3) the third step; In the second step, kaolin and bentonite were sequentially added and stirred for a sufficient time. Subsequently, it was lowered to about 40 ° C, which is a temperature suitable for the fourth step described later.

The temperature range in the third step is preferably about 40 ° C., but is limited to 38 to 42 ° C. in consideration of the type of material added to the third step.

(4) Fourth step: Hot plated Cetyl alcohol, Polysorbate 60, Sorbitan monostearate, jojoba oil heated to 65 ~ 75 ℃ To prepare an oil part.

(5) 5th step: The oil part of the 4th step was added to the 3rd step (the state lowered to 38-42 ° C), and mixed using a mixer and a stirrer. However, in the case of Sample 3 and Sample 4, polyacrylamide was added, and then cooled to complete production.

[Sensory evaluation]

After preparing a wash-off pack having the same composition ratio as in Samples 1 to 5, 20 evaluators were subjected to "sensory evaluation" to evaluate the stability, usability, cleansing effect, and sebum removal effect of the wash-off pack. The sensory evaluation was conducted by the question-and-answer method and is summarized as in Table 3.

division Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Pack stability 4.8 4.8 3.1 2.7 4.2 Usability 4.9 4.7 1.4 1.5 3.3 Cleansing effect 4.8 4.8 2.6 2.7 4.1 Exfoliation 4.6 4.9 1.3 2.2 4.6 (1 point: Very bad, 2 points: Bad, 3 points: Normal, 4 points: Good, 5 points: Very good))

As shown in Table 3, the wash-off pack according to the present invention was judged to have excellent stability, good feeling of use, and good cleansing and exfoliation effect. However, in the case of samples 3 and 4 prepared by adding the polyacrylamide, the stability and usability of the pack were not good.

In the case of the sample 3, the stability of the clay was higher than that of the sample 4, and the stability was evaluated a little higher, but it was judged to be unsuitable for use as in the sample 4, and when the polyacrylamide was added, the stability of the pack decreased. Was confirmed.

In the case of Sample 5, the cleansing effect and the exfoliation effect were excellent, but the amount of stone cells was very large enough to be confirmed even with the naked eye. Before using the wash-off pack, the evaluators answered that the amount of stone cells was large, so that it was burdensome to apply, and evaluated that the feeling of use was poor when exfoliating.

In the case of Sample 1 and Sample 2, the amount of stone cells was reduced by more than half compared to Sample 5, and the stability, usability, cleansing, and exfoliation effects were positively evaluated. Based on the above evaluation, if it has the same composition ratio as Sample 1 and Sample 2, it is predicted to be suitable for the wash-off pack.

And, Figure 1 is a photograph taken by the SEM of the stone cells, the left and right pictures are not exactly the same form, but similar. The reason that the pictures show different appearances is due to agglomeration between particles in the drying process, and it is judged that there is a difference in magnification and a difference in the sample itself.

In other words, after drying the stone cells, it was predicted that stone cells having a non-uniform size were obtained by crushing the ones stuck to each other using a mortar, and although the particle size photographed through the SEM was not uniform, the stone cells were The fact that it was obtained was clearly confirmed.

Since the particle size of the stone cell scrub agent is non-uniform, it is expected that the exfoliation effect is excellent when the particle size of the stone cell scrub agent is uniform.

And, Figure 2 is a picture for explaining the cleaning power of the wash-off pack, in order to test the cleansing effect of the composition, a cosmetic product was applied to the wrist and a certain amount of pack was applied. As a result of applying the wash-off pack for a certain period of time and wiping it off with hot water, it was found that the cosmetic product was cleanly removed and the cleaning power was excellent.

That is, the composition according to the present invention is excellent in cleansing function for cosmetics, and in particular, it can not only exfoliate using the stone cells. It can also serve to provide sufficient moisture to the skin.

Especially. The composition according to the present invention adds septic cells having an exfoliation effect and chitosan having an antibacterial effect, as well as grafting surfactants having a cleansing effect, thus using the wash-off pack and separate cleansing after washing. It was found that it is possible to reduce the number of cosmetic steps because it is not necessary.

The above description is only an embodiment of the present invention, and a person having ordinary knowledge in the technical field to which the present invention pertains may be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be interpreted to include various embodiments within a range equivalent to that described in the claims.
