Amino acid-based face wash composition with bead-type cosmetic phase

The amino acid-based face wash composition according to an embodiment of the present invention includes purified water as a solvent phase, a glutamate-based compound, an acrylate-based polymer, and an amino acid-based compound as a cosmetic phase, wherein the cosmetic phase has an independent bead shape in the solvent phase will have

The amino acid-based face wash composition of the present invention includes a plurality of independent bead-shaped cosmetic phases, so that even a small amount of surfactant can form a large amount of bead-shaped cosmetic phase in a water-soluble solvent, and the face wash composition When used on the skin, cleansing can be performed gently without irritation. In addition, unlike a conventional face wash composition containing a scrub, there is no skin irritation and the bead-type cosmetic phase itself has excellent cleaning power, so that skin wastes and makeup residues can be easily removed.

As a result of intensive research, the present inventors have found that, as a result of intensive research, the use of an amino acid face wash is minimized, and a number of bead-shaped cosmetic phases are stabilized inside the composition and placed inside the composition. found to be able to represent

As the solvent phase, purified water may preferably be ultrapure purified water. General purified water is water generally used in pharmaceuticals and cosmetics, and has a dissolved solid content of 1.0 to 0.5 ppm indicating purity, a size of 0.2 to 0.45 μm of a filter used to remove particulates and microorganisms in the manufacture of purified water, and a pH of It varies from weak acid to weak alkali. The ultrapure purified water has a very high purity with a dissolved solids content of 0.03 ppm, and the size of the filter used in preparing ultrapure purified water is 0.001 μm. In particular, ultrapure purified water can prevent the auto-oxidation reaction of the composition by removing metal ions as well as prevent protein aggregation by metal ions, so that the formulation can be evenly applied while being hypoallergenic to the skin.

The cosmetic phase has an independent bead shape in purified water as a solvent, and a plurality of phases may be included. This bead shape can ensure stable storage stability in the layer separation phenomenon during long-term storage of the oil-in-water face wash composition. In addition, it is possible to secure more stable storage stability by suppressing phenomena such as sedimentation or floating during long-term storage of a face wash composition containing a scrub or beads of plant seeds, cellulose, agar, and the like.

In addition, the face wash composition of the present invention may have a high foaming ability due to rapid inversion when foam is generated before application to the skin.

The cosmetic phase specifically includes a glutamate-based compound, an acrylate-based polymer, and an amino acid-based compound.

Specifically, the glutamate-based compound may include at least one selected from the group consisting of sodium stearoyl glutamate, sodium lauroyl glutamate, sodium myristoyl glutamate, and sodium cocoyl glutamate.

The acrylate-based polymer can be evenly dispersed and distributed in a solvent without problems such as sedimentation or floating on the bead-type cosmetic while maintaining the bead shape on the cosmetic, and is included for the purpose of having compatibility with the glutamate-based compound.

Specifically, the acrylate-based polymer may include at least one selected from the group consisting of an acrylate copolymer, a carbomer, and an acrylate/C10-30 alkyl acrylate crosspolymer.

The amino acid-based compound is used as a neutralizing agent, and reacts with the glutamate-based compound to form a bead-type cosmetic phase. The amino acid-based compound may specifically include at least one selected from the group consisting of lysine, arginine, and histidine.

In the face wash composition of the present invention, for stable maintenance of the bead-type cosmetic phase, the weight ratio of the solvent phase and the cosmetic phase may be set to 1: 0.05 to 0.3 by weight based on the solvent phase. If the weight ratio of the cosmetic phase exceeds the above range, the composition of the cosmetic phase is excessive and may affect the stability of the oil-in-water face wash composition. If the weight ratio of the cosmetic phase is less than the above range, the bead shape may not be formed correctly due to insufficient raw materials.

According to an embodiment of the present invention, the face wash composition contains 3 to 10 parts by weight of a glutamate-based compound, 1 to 5 parts by weight of an acrylate-based polymer, and 0.5 to 4 parts by weight of an amino acid-based compound, based on 55 to 105 parts by weight of purified water. it may be

If the weight ratio of the glutamate-based compound is out of the above range, the bead-type cosmetic phase may not be easily formed.

If the acrylate-based polymer exceeds the above range, the bead-type cosmetic phase may become a hard solid, and if it is less than the above range, the bead-type cosmetic phase may be formed in a fine size, or may not be easily formed.

By including the amino acid-based compound within the above range, it is possible to effectively form a bead-type cosmetic phase. In particular, according to an embodiment of the present invention, if the weight ratio of the amino acid-based compound is less than the above range, a large number of unreacted acrylate-based polymers are present in the face wash composition, and a very dense bead-type cosmetic phase may be formed. Also, the viscosity of the face wash composition may be lowered. If it exceeds the above range, the acrylate-based polymer remaining in the face wash composition may be insufficient, and for this reason, the acrylate-based polymer and the glutamate-based compound do not react, thereby making it difficult to form a bead-type cosmetic phase.

In addition, the weight ratio of the acrylate-based polymer and the amino acid-based compound as a neutralization ratio may affect the size and shape of the bead-type cosmetic phase to be formed. Specifically, the weight ratio of the acrylate-based polymer to the amino acid-based compound may be 1:0.4 to 1 for the amino acid-based compound based on the acrylate-based polymer. If it is less than the above range, the size of the bead-type cosmetic phase may be formed too small and may be changed to a bubble shape. A face wash composition in a transparent form may be formed without

The ingredients included in the face wash composition of the present invention include ingredients commonly used in face wash compositions as active ingredients, for example, conventional adjuvants such as antioxidants, stabilizers, solubilizers, vitamins, pigments and fragrances, and carriers. can do. In addition, as another component having a preservative function, it may include any one or more of ethylhexanediol and glyceryl caprylate.

Method for producing an amino acid-based face wash composition containing a bead-type cosmetic phase

The bead-type cosmetic phase of the face wash composition is difficult to produce in a one-component reaction, and may be subjected to the following process.

Specifically, mixing an acrylate-based polymer and purified water as one solution and heating to 60 to 90° C., mixing a glutamate-based compound and purified water as a second solution and heating to 60 to 90° C., the first and second solutions Heating while mixing, mixing and then dissolving the amino acid-based compound and purified water as three liquids, and mixing the three liquids with the first and second liquid mixtures to prepare a cosmetic phase having a bead shape will be.

As can be seen above, it is preferable that the face wash composition of the present invention proceed as a three-component reaction in a separate container.

The first liquid should contain a relatively high content of purified water compared to the second and third liquids. If the content of purified water is not sufficient during the production step of the first liquid, a thin crystalline cosmetic phase may be formed, not the bead-type cosmetic phase, when mixed with the second liquid. Therefore, it is preferable to include the acrylate-based polymer and purified water in a weight ratio of 1:9 to 20 based on the acrylate-based polymer at all times in one solution.

Specifically, in one solution, based on 40 to 60 parts by weight of purified water, 1 to 5 parts by weight of the acrylate-based polymer may be included and mixed.

In a separate container, as two liquids, based on 10 to 30 parts by weight of purified water, 3 to 10 parts by weight of a glutamate-based compound may be included and mixed.

The first and second solutions may be mixed simultaneously or individually regardless of a separate order. The first and second solutions may include a step of heating to 60 to 90° C. while mixing to complete dissolution.

The three liquids should be added after the first and second liquids are mixed, and only through these steps can a dense spherical bead-type cosmetic phase be formed.

The third solution may be mixed with 0.5 to 4 parts by weight of an amino acid-based compound based on 5 to 15 parts by weight of purified water in a separate container and then dissolved, and then added to the mixed solution of the first and second solutions.

By going through the manufacturing process as described above, while the cosmetic phase is stabilized and placed inside the composition, it can exhibit a superior effect than the existing cleansing products due to rapid inversion when applied to the skin, and a plurality of bead-type cosmetic phases are stably dispersed even when stored for a long time and can have a high bubble retention rate.
