Description

Mask Pack which has short adhesion time and improved skin elasticity and moisturizing}

The present invention relates to a mask pack cosmetic, and more particularly, to a mask pack cosmetic with improved skin elasticity and moisturizing power by reducing the skin adhesion time of the nonwoven sheet.

These days, the desire to pursue beauty has become more intense, and awareness of skin care has become common with the expectation of a moist and elastic skin regardless of gender, but it takes a lot of time and money due to the busy life of modern people. The demand for mask pack products that can be used conveniently at home rather than in a skin care room is continuously increasing.

This is because environmental pollution has become serious due to the rapid improvement of living standards, and the frequency of use of mask packs by urban women who are concerned about skin damage has started to increase, and consumers who want convenient and quick effects have increased.

In the cosmetic field, there are three types of sheet-type masks.

The first is a mask pack in which a non-woven fabric made of cotton or pulp-type vegetable cellulose fibers or synthetic fibers such as nylon or DuPont is used as a mask-shaped support and immersed in liquid cosmetics.

The second is a hydrogel-type mask pack made of natural polysaccharides such as natural agar, carrageenan, and logger beast gum.

Third, it is a mask pack that is immersed in liquid cosmetics using biocellulose made through microbial culture as a mask-shaped support.

The most universally used is a form in which a nonwoven sheet is solubilized in a liquid (purified water, etc.) of 85.0% by weight or more based on the total weight of the composition, and then immersed in a liquid cosmetic to which a thickener is added.

Liquid cosmetics deposited on the sheet are limited in activity for 20 to 30 minutes required for absorption or evaporation in the skin.

Liquid cosmetics are deposited on a nonwoven sheet, and if the viscosity is low, the adhesion is weakened, and if the viscosity of the liquid is increased by increasing the amount of thickener, the degree of deposition on the nonwoven fabric worsens, and to increase the moisturizing power by increasing the amount of oil, the mask pack function. Is lost.

In addition, since it adheres to the skin in a form deposited in a liquid phase, it is difficult to impart elasticity due to poor adhesion.

In order to improve adhesion, Korean Patent Laid-Open No. 10-2018-0018904 consists of a nonwoven sheet impregnated with (a) a first agent containing alcohol and (b) a second agent containing tamarind seed gum, and the first agent ( A) and a non-woven sheet (b) impregnated with the second agent are posted on a cosmetic mask pack with improved adhesion and moisturizing power. However, since the invention of this document also adheres to the skin in a form deposited in a liquid phase, it is difficult to impart elasticity due to poor adhesion.

In addition, in rare cases, a dry mask pack is used. In this case, as published in Korean Patent Registration No. 10-1858451, the active ingredient is immersed in a sheet and solidified to provide it in a solid state, and then soaked in water. This is the form to be used next.

This also has disadvantages such as having to wet the water and use it, and if the concentration is not properly adjusted, the active ingredients flow down with water.

Alginic acid is obtained from brown algae such as seaweed and kelp, which are the most distributed among marine plants. D-mannuronic acid and L-gluronic acid are a kind of polysaccharide consisting of α-1,4 or β-1,4 bonds. It is found in seaweed as a broad component of the cell wall in some mixed form, especially in the form of sodium salts. Alginic acid is most commonly used as a sodium salt. It has no side chains structurally and is composed of hydrogen and hydroxyl groups with strong hydrophilicity, so it has strong hydration properties. It works.

Alginic acid is widely applied as a raw material for medical and food applications due to its affinity and safety for the body. It has a high moisture-absorbing ability, biodegradability, lubricity, and moldability that absorbs more than 200-300 times its own weight, and is non-toxic. Have. In cosmetics, seaweed extract is generally known to be used to protect and hydrate the skin to soften it. Seaweed extract, a natural ingredient, is non-toxic, so it does not irritate the skin and eyes, does not have microbiological contamination, and is used as a stable raw material that is unfavorable for microbial growth.

In cosmetics, as a thickener that increases mucus, it is used in lotions, creams, ointments, etc. In addition, it has the effect of film formation, protective colloidality (emulsification), foam stability, and shape retention, so it forms a film with moisture. It is an excellent raw material. Moisturizing power can be improved by making the oils and alginic acid dispersed and hydrated in the liquid phase at high temperature form a skin protective film.

If these effects are properly controlled, it is possible to provide a mask pack with improved skin elasticity and moisturizing power while the use time is as short as 20 to 30 seconds.

As a result of intensive research efforts to overcome the problems of the prior art, the present inventors produced a mask pack cosmetic consisting of a first agent (a) and a nonwoven sheet (b) containing oils and alginic acid, and the contents (agent 1, essence, etc.) The nonwoven fabric sheet is applied to the skin, and then the nonwoven fabric sheet is attached to the skin, pressed with the palm of the hand, and the contents are brought into close contact between the skin and the nonwoven fabric sheet to increase skin adhesion, and then the nonwoven fabric sheet adhered to the skin is immediately removed. The skin attachment time of the sheet could be drastically shortened to 20 to 30 seconds compared to the previous 20 to 30 minutes.

In addition, when removing the non-woven sheet, it was possible to improve skin elasticity by pulling up the skin adhered to the non-woven sheet, and it was confirmed that the moisturizing power was improved by allowing the oils and algingan contained in the contents (agent 1) to form a film. Was completed.

In a conventional mask pack, a non-woven sheet is solubilized in a liquid (purified water, etc.) of 85.0 wt% or more based on the total weight of the composition, and then immersed in a liquid cosmetic with a thickening agent. There is a restriction on activity for 20 to 30 minutes to be absorbed or evaporated into the skin, and increasing the viscosity of the liquid by increasing the amount of thickener deteriorates the degree of deposition on the nonwoven fabric, and emulsification is required to increase the moisturizing power by increasing the amount of oil. The mask pack function will be lost.

In addition, since the liquid cosmetics are deposited on a nonwoven sheet, the viscosity is low, so the adhesion is weakened, and thus the skin elasticity cannot be imparted and moisture persistence is poor.

In contrast, the present invention relates to a mask pack consisting of a non-woven sheet and a first agent containing oils and alginic acid, unlike the prior art, and was derived to improve the skin adhesion time, elasticity effect, and moisturizing power of the non-woven sheet. The problem of can be improved.

The oils included in the present invention may be any vegetable oil, such as grape seed oil (Vitis Vinifera (Grape) Seed Oil), macadamia seed oil (Macadamia Ternifolia Seed Oil), jojoba seed oil (Simmondsia Chinensis (Jojoba) Seed Oil). ), Argania Spinosa Kernel Oil, Sunflower Seed Oil (Helianthus Annuus (Sunflower) Seed Oil), Evening Primrose Oil (Oenothera Biennis (Evening Primrose) Oil), Olive Oil (Olea Europaea (Olive) Fruit Oil), Camellia Oil (Camellia Japonica Seed Oil), coconut oil (Cocos Nucifera (Coconut) Oil), chamomile oil (Chamomilla Recutita (Matricaria) Oil) may contain one or more selected from the group consisting of.

The content of oils in the first agent is characterized in that it is contained in 3 to 8% by weight based on the total weight of the composition. If the content of oils is less than 3.0% by weight, it cannot be emulsified, so the moisturizing power is lowered. In addition, when the content of oils is 8.0% by weight or more, it changes to a creamy form, so it becomes a cream form, not a mask pack, and the sheet adhesion is significantly lowered.

The content of alginic acid in the first agent is characterized in that it is contained in 0.5 to 1.5% by weight based on the total weight of the composition. If the content of alginic acid is less than 0.5% by weight, the viscosity of the nonwoven fabric is lowered and the nonwoven fabric does not adhere well, so it is difficult to achieve the object of the present invention.If the content of alginic acid is more than 1.5% by weight, the viscosity increases and the feeling of use is heavy and frustrating. When attached to the skin, it is difficult to increase the satisfaction of the skin, and the moisture of the residue remaining after the sheet is removed may evaporate and become lumped and pushed out.

Further, if necessary, an additional thickener may be further contained. As a thickener, Xanthan Gum, Algin, Carrageenan, Gelatin, Guar Gum (Cyamopsis Tetragonoloba (Guar) Gum), Dextrin, Cellulose (Cellulose, Methylcellulose, ethylcellulose, hydroxyethylcellulose (Hydroxyethylcellulose), hydroxypropylcellulose (Hydroxypropylcellulose), methylhydroxyethylcellulose (Methyl Hydroxyethylcellulose, etc.) I can.

In the present invention, the first agent is characterized in that it further comprises at least one selected from the group consisting of purified water, water-soluble or oil-soluble additives, surfactants, flavors, or preservatives in addition to thickeners such as oils and alginic acid.

In the present invention, the first agent and the nonwoven sheet are contained in separate containers. For example, the first agent is contained in a bottle, tube, blow, etc., and the non-woven sheet may be contained in a pouch, preferably, agent 1 and agent 2 are contained in a laminated pouch such as PET/AL/LLDPE. Can be used as

The nonwoven sheet may include at least one selected from cotton or pulp-type vegetable cellulose fibers or nonwoven fabrics made of synthetic fibers such as nylon or polyethylene, polypropylene, and polyester.

In addition to the shape of the face, the shape of the nonwoven sheet is made in various shapes such as round, oval, square, rectangular, and star shape, and can be applied to areas such as arms that need special care in addition to the face.

In the present invention, the first agent and the nonwoven sheet are sequentially applied to the skin.

Specifically, the separated first agent is first applied evenly to the skin, and the nonwoven sheet is pressed with the palm covered thereon to increase skin adhesion. Thereafter, by immediately removing the nonwoven fabric sheet in close contact with the skin, the skin attachment time of the nonwoven fabric sheet can be dramatically shortened to 20 to 30 seconds compared to the existing 20 to 30 minutes.

In addition, when removing the nonwoven fabric sheet, it is possible to improve skin elasticity by pulling up the skin adhered to the sheet. In addition, the oils and alginic acid contained in the contents form a film to help improve moisturizing power.

The present invention will be described in detail by the following examples and test examples.

Example 1: Preparation of mask pack

It was prepared as follows in the composition of Table 1 below.

In the first step (aqueous phase) of the first agent, the moisturizing agent and alginic acid were completely dissolved in purified water. A cellulose thickener separately dissolved in this solution was added, stirred sufficiently for 15 minutes, and heated to 75-80°C. In the second step (oil phase), surfactant, vegetable oil, emulsifying aid, and butter were mixed and heated to 75~80℃ to completely dissolve. In 3 steps, the oil phase (step 2) was completely emulsified in the heated water phase (step 1) using a homo blender for 5 to 10 minutes. After confirming that it was completely emulsified, it was cooled to 50° C. and then vegetable extracts, moisturizers, preservatives, and functional ingredients were added, followed by sufficiently stirring for 5 minutes.

After applying the first agent prepared in the composition of Table 1 to the face (Fig. 1 a), after attaching a dry cellulose nonwoven fabric sheet in the shape of a face to the face to which the first agent was applied (Fig. 1 b), 30 seconds with the palm of the hand Press for a while, after the first agent's contents bring the skin and the nonwoven sheet into close contact, it is immediately removed (Fig. 1 c). As shown in the photograph of FIG. 1C, after applying the mask pack of the present invention, the contents do not flow down even after the nonwoven sheet is removed, and the appropriate viscosity is maintained, so that make-up is possible immediately.
