Description

Composition of resident type facial mask

Technical Field

The present invention relates to a composition for a facial mask, and more particularly, to a composition for a leave-on facial mask which is transparent, easily removable, does not tighten, and effectively isolates color cosmetics and resists the attachment of contaminants.

Background

Recently, people pay attention to health and beauty of the face, wherein the facial mask has the effects of moisturizing, whitening, cleaning and the like, and is a popular and commonly used facial product. Currently, the commercial masks include cleansing masks, patch masks, and peel masks, wherein the peel mask generally comprises polyvinyl alcohol (polyvinyl alcohol, PVA)/polyvinylpyrrolidone (PVP).

Although the various masks described above have many advantages, they have disadvantages. For example, cleansing masks do not form a thin and uniform elastic film on the skin, but do not isolate make-up and resist adhering contaminants. Furthermore, the patch type mask does not have a transparent appearance, and can not be used for making up on the mask, and can not be used for isolating make-up and resisting attachment of pollutants. In addition, the PVA/PVP peel-off mask has a transparent appearance, but the mask is not breathable and taut, is not suitable for long-term use, is susceptible to damage to the keratinous tissue upon peeling, and is not resistant to the attachment of contaminants.

In view of the foregoing, there is a need to develop a composition for a resident facial mask to improve the above-mentioned disadvantages of the conventional facial mask.

Detailed Description

The application of embodiments of the present invention is discussed in detail below. However, it is to be understood that the embodiments provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The particular embodiments discussed are merely illustrative and are not meant to limit the scope of the invention.

The invention provides a composition of a resident type facial mask, which is characterized in that the usage amount of a film forming agent (A) and the weight ratio of the film forming agent (A) to a moisturizing penetrating agent (B) of the composition are controlled, so that the formed facial mask provides a transparent appearance, and after a preset period of use, good comfort, skin adhesion, stripping easiness and moisturizing effect are maintained, and color cosmetics and anti-adhesion pollutants can be effectively isolated. Furthermore, the peeling mask does not cause skin cutin damage due to good peeling easiness, and the mask can be peeled off after a small amount of normal-temperature water is used for wetting the mask, and meanwhile, the color makeup on the mask is removed. In addition, the transdermal permeability of the active additive (G) is enhanced by the moisturizing osmotic agent (B) to enhance the efficacy of the active additive (G).

In other words, the composition of the resident facial mask comprises a film forming agent (A), a moisturizing penetrating agent (B), a rheology modifier (C), a wetting agent (D) and water (E). The film former (A) referred to herein is an aqueous polymer. In some embodiments, film former (A) includes, but is not limited to, polyurethane-35 (Polyurethane-35) (A-1). Polyurethane-35 (A-1) may be commercially available, for example, aqueous polyurethane manufactured by Covesro corporation (Covesro), which is a copolymer synthesized from monomers such as adipic acid (adipic acid), dicyclohexylmethane diisocyanate (dicyclohexylmethane diisocyanate), ethylenediamine (ethylene), hexanediol (hexandiol), neopentyl glycol (neonyl glycol), sodium N- (2-aminoethyl) -3-aminoethane sulfonate (sodium N- (2-aminoethyl) -3-aminoethane sulfonate), and the like.

According to an embodiment of the present invention, the film former (a) is used in an amount of more than 8 to less than 22 weight percent based on 100 weight percent of the total composition. When the film former (a) is used in an amount of 8 weight percent or less, the thus-formed mask is not easy to peel off. When the film former (a) is used in an amount of 22 wt% or more, the resulting mask may be too thick, easily resulting in tight skin and poor comfort. Preferably, the film former (a) is used in an amount of 10 to 20 weight percent. More preferably, the film forming agent (A) is used in an amount of 12 to 15 weight percent, and the facial mask formed thereby provides better comfort, skin adhesion, stripping easiness and moisturizing effect.

In the composition of the resident type mask of the present invention, the moisturizing penetrant (B) referred to herein means a moisturizing agent that helps the active additive (G) penetrate into the skin and enhances the efficacy of the active additive (G) by increasing the solubility of the active additive (G) to the skin. In some embodiments, the moisturizing osmotic agent (B) includes, but is not limited to, polyoxyethylene polyoxypropylene polyoxybutylglycerol. Polyoxyethyl polyoxypropyl polyoxybutyl glycerol is a compound obtained by adding polyoxyethyl, polyoxypropyl, and polyoxybutyl groups to three hydroxyl groups of glycerol. In one embodiment, the polyoxyethylene polyoxypropylene polyoxybutylglycerol may be PEG/PPG/polybutyleneglycol-8/5/3 glycerol (PEG/PPG/polybutylene glycol-8/5/3 glycon) (B).

According to an embodiment of the present invention, the weight ratio of the film former (a) to the moisturizing penetrant (B) may be 2.4 to 12, based on 100 weight percent of the total composition. When the weight ratio of the film forming agent (A) to the moisturizing penetrating agent (B) is less than 2.4, the formed mask cannot be peeled off in a whole piece after being wetted by water, or has a sticky feel. When the weight ratio of the film forming agent (a) to the moisturizing penetrating agent (B) is more than 12, the resulting mask may cause skin to be stretched, causing discomfort to the user. Preferably, the weight ratio of the film former (a) to the moisturizing penetrating agent (B) is 2.4 to 5.

According to an embodiment of the present invention, the film forming agent (a) is used in an amount of more than 8 wt% to less than 22 wt% based on 100 wt% of the total composition, and the weight ratio of the film forming agent to the film forming agent is 2.4 to 12, so that the composition can form a transparent facial mask on the skin, has high elasticity, and can provide high skin adhesion and good air permeability. In addition, after the mask is used for a period of preset time, the formed mask still keeps good comfort, skin adhesion, stripping easiness and moisturizing effect, and can effectively isolate color cosmetics and pollutants.

According to an embodiment of the present invention, the moisture-preserving penetrant (B) may be used in an amount of 0.5 to 5.5 wt%, based on 100 wt% of the total composition. When the moisture-retaining penetrant (B) is used in an amount of 0.5 to 5.5 weight percent, the thus-formed mask has excellent moisture-retaining effect. Preferably, the moisture-retaining penetrant (B) is used in an amount of 1 to 5 wt%, and more preferably 3 wt%.

In the composition of the resident type mask, the rheology modifier (C) is used for adjusting the viscosity of the composition so that the composition can be uniformly coated on the face to form a mask with thin and uniform thickness, thereby providing breathable comfort and good skin attachment degree in use. In some embodiments, the rheology modifier (C) comprises at least one of a polymer of acrylic acid and/or derivatives thereof. The aforementioned acrylic acid derivatives include, but are not limited to, acrylic esters, salts of acrylic esters, alkyl acrylic acids having 10 to 30 carbon atoms, or acrylamides. In some embodiments, the aforementioned polymers may also comprise monomers of vinyl isodecanoate in addition to acrylic acid and/or derivatives thereof. Further, the aforementioned polymer may be a homopolymer or a copolymer, or the aforementioned polymer may be a crosslinked polymer.

In some embodiments, rheology modifier (C) includes, but is not limited to, acrylate copolymer (acrylate copolymer), sodium polyacrylate (sodium polyacrylate), acrylic acid/alkyl acrylic acid crosslinked polymer having 10 to 30 carbon atoms (acrylic acid/C10-30 alkyl acrylate crosspolymer), methyl methacrylate crosslinked polymer (methyl methacrylate crosspolymer), hydroxyethyl acrylate/sodium acryloyldimethyltaurate copolymer (hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer), acrylate/vinyl isodecanoate crosslinked polymer (acrylate/vinyl isodecanoate crosspolymer), acrylic acid/vinyl isodecanoate crosslinked polymer (acrylic acid/vinyl isodecanoate crosspolymer), or acrylamide dimethyltaurate/VP copolymer (ammonium acryloyldimethyl taurate/VP copolymer). In other embodiments, the rheology modifier (C) comprises a combination of at least two of the foregoing polymers.

According to an embodiment of the present invention, the rheology modifier (C) is used in an amount of 0.1 to 2 weight percent based on 100 weight percent of the total composition. When the rheology modifier (C) is used in an amount of 0.1 to 2 weight%, the thickness of the thus formed mask is thin and uniform, and it can provide breathable comfort and good skin-contact. Preferably, the rheology modifier (C) is used in an amount of 0.4 weight percent.

In the composition of the leave-on mask, the humectant (D), herein referred to as humectant (D), refers to a hydrophilic compound that helps to wet the mask when it is desired to strip the mask, so that the mask can be easily stripped in whole. Accordingly, the mask formed by the resident mask composition can be easily stripped without pulling the skin.

In some embodiments, the wetting agent (D) is selected from the group consisting of liquid polyols, water-soluble alkoxylated nonionic polymers, and any combination thereof. The liquid polyol may comprise a polyol having 2 to 8 carbon atoms. For example, the liquid polyol may be ethylene glycol, propylene glycol, butylene glycol, pentylene glycol (pentalene glycol), 1,2-hexanediol (1, 2-hexanediol), octylethylene glycol (capryl glycol), decylene glycol (decylenyl glycol), glycerin, ethylhexyl glycerin (ethylhexyl glycerin), sorbitol, methylbenzyl alcohol (methylbenzyl alcohol), maltitol, etc. The water-soluble alkoxylated nonionic polymer may include, but is not limited to, polyglycerol, dipropylene glycol (dipropylene glycol), ethoxydiglycol (ethoxydiglycol), ethylhexyloxyglycerol (ethylenexydiglycerin), and the like. In other embodiments, the humectant (D) may optionally include, but is not limited to, hyaluronic acid, chitosan, trehalose, and beta-glucan and sugar derivatives, and the like.

According to one embodiment of the present invention, the wetting agent (D) is used in an amount of 5 to 8 weight percent based on 100 weight percent of the total composition. When the amount of the humectant (D) is 5 to 8 weight%, the mask formed therefrom can be peeled off in whole after being wetted with water, to provide convenience in peeling after use. Preferably, the humectant (D) is used in an amount of 5 weight percent.

In the resident facial mask composition of the present invention, the resident facial mask composition may optionally contain a functional additive (F) and/or an active additive (G). The functional additive (F) referred to herein means an additive capable of providing functions such as pH adjustment, emulsification, dispersion, dissolution, skin moisturizing, or antibacterial. In some embodiments, the functional additive (F) is at least one selected from the group consisting of a pH adjuster (F1), a surfactant (F2), an emollient (F3), an antimicrobial agent (F4), and ethanol (F5). The active additive (G) is an additive capable of providing whitening, antioxidation or allergy relief functions. In some embodiments, the active additive (G) is at least one selected from the group consisting of whitening agent (G1), antioxidant (G2) and a sensitivity agent (G3).

The composition of the resident facial mask of the invention can enhance the percutaneous permeability of the active additive (G) through the moisturizing penetrating agent (B) so as to improve the efficacy of the active additive (G).

The composition of the resident facial mask is directly coated on facial skin, and the pH value of the composition can be adjusted by using a pH regulator (F1) to be close to the pH value of the skin so as to avoid skin irritation, wherein the pH value of the composition can be 5 to 8, preferably 6 to 7. The pH adjustor (F1) includes, but is not limited to, small-molecule organic amines, organic weak acids or inorganic alkali salts. Organic amines include, but are not limited to, basic amino acids or lower carbon amine alcohols. For example, the pH adjustor (F1) may be arginine (arginine), 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1, 3-propanediol, triethanolamine (triethanolamine), citric acid, or the like. Inorganic base salts include, but are not limited to, alkali metal salts. For example, alkali metal salts include, but are not limited to, sodium hydroxide or potassium hydroxide, and the like.

For example, anionic surfactants include, but are not limited to, sodium stearyl glutamate (sodium stearoyl glutamate), potassium cetyl phosphate (potassium cetyl phosphate), phosphate salts, and the like. Specific examples of phosphate salts are lecithins (lecithins), hydroxylated lecithins (hydroxylated lecithin), hydrogenated lecithins (hydrogenated lecithin) and the like, wherein the hydrogenated lecithins are hydrogenated lecithins and have moderate skin adhesion and dispersibility to water, so that the hydrogenated lecithins can increase the ease of stripping by hand of the mask formed from the composition.

For example, nonionic surfactants include, but are not limited to, sorbitan fatty acid esters, sorbitol fatty acid esters, alkyl ethers, and the like. Specific examples of fatty acid esters include ethylhexyl hydrogenated olive oleate (hydrogenated ethylhexyl olivate) and hydrogenated olive oil unsaponifiable matter (hydrogenated olive oil unsaponifiables). Ethylhexyl hydrogenated olive oleate and hydrogenated olive oil unsaponifiables can be used as emulsifiers to aid in the emulsification of oily molecules added to the composition.

Among the functional additives (F), the emollient (F3) is capable of moisturizing the skin, and making the skin tender. Some emollients (F3) may act as moisture blocking agents. When the emollient (F3) forms a protective film outside the stratum corneum of the skin, the protective film can prevent water loss, thereby making the skin tender and transparent.

In the present invention, the emollient (F3) is not particularly limited, and any emollient such as a composition which can be added to a mask as generally known can be used. In some embodiments, the emollient (F3) includes, but is not limited to, fatty acids and esters thereof, cholesterol (cholesterol) and esters or amino acid derivatives thereof, hyaluronic acid and salts thereof, and the like.

In some embodiments, the antimicrobial agent (F4) includes, but is not limited to, propolis or Leuconostoc/radix Raphani fermentation filtrate (leuconostoc/radish root ferment filtrate), and the like. In other embodiments, a plurality of embodiments of the antibacterial agent (F4) may be mixed and used.

Among the active additives (G), the whitening agent (G1) is used for preventing, inhibiting and/or reducing the formation and/or precipitation of skin melanin and the like, and thereby achieving a whitening effect. The whitening effect referred to herein means that after skin is treated with 30% dihydroxyacetone (dihydroxyacetone) solution for 40 minutes, after waiting for the keratin to be sufficiently brown, the composition of the resident facial mask is coated, stripped after 8 hours, and continuously carried out for 5 days at a frequency of once per day, and then skin melanin content and L value of the skin are measured by using a skin black/red pigment probe and a skin tone probe to obtain individual type angles (individual typological angle, ITA), and the variation rates of melanin content, L value and ITA are calculated, and the evaluated whitening effect is carried out.

In the present invention, the whitening agent (G1) is not particularly limited, and as conventionally known whitening agents which can be added to a composition of a mask, can be used. In some embodiments, the whitening agent (G1) includes, but is not limited to, synthetic compounds and/or natural plant extracts.

Fig. 5A shows that the color cosmetics were applied to the mask formed of the mask composition of example 2 without halation, and the color cosmetics on the mask had the same make-up feel as the color cosmetics on the skin. In addition, the makeup on the mask can be removed while peeling off the mask after wetting the mask with a little water at normal temperature. As described above, since the mask of example 2 has good peeling easiness and can effectively isolate the makeup, the makeup can be easily and completely removed while peeling the mask. The skin without the mask is washed with water, but the makeup cannot be removed by a large amount of water. The foregoing results show that: the mask composition of example 2 formed a mask with good ease of make-up removal.

9. Whitening effect

The whitening effect test was to evaluate the whitening effect of the compositions of examples 8 to 10, comparative examples 6 to 7 with or without coating in 4 subjects. The skin of the arm of the subject was washed with a foam cleanser of 12% sodium laureth sulfate (sodium lauryl ether sulfate, SLES) and then was washed with a foam cleanser having an area of 2cm ² The skin was left to be rinsed with a 30% dihydroxyacetone solution for 40 minutes and left to stand for 24 hours to fully brown the skin keratin to simulate a tanned skin condition, the appearance of which is shown in fig. 6A. Then, the skin melanin content and L values of the subject's skin were measured with a skin black/red pigment probe (Mexameter MX18, courage-Khazaka electronic GmbH, germany) and a skin tone probe (Colorimeter CL400, courage-Khazaka electronic GmbH, germany), and individual type angles (individual typology angle, ITA) were calculated as skin "pre-treatment" data.

The skin black/red color probe is a probe that obtains the amount of light absorbed by the skin by measuring the amount of light reflected after the skin is irradiated with light of a known amount of light of a specific wavelength, and represents the melanin content in any colorimeter unit (arbitrary mexameter unit).

ITA is a skin color measurement index established based on CIE (international commission on illumination) L x a x b x color space, wherein the higher the ITA, the better the whitening effect, and the ITA can be calculated by the following formula (I): ITA (degree) = { Arc Tangent [ (L-50)/b ] } ×180/pi (I)

L represents darkness and has a value from 0 (black) to 100 (white)

The value b represents the yellow/blue luminosity

Then, the compositions of examples 8 to 10 and comparative examples 6 to 7 were applied to the skin of the subject to form a mask, wherein the application amount of the composition was 120mg, and the mask was peeled off after 8 hours. After continuous 5 days at once daily frequency, the skin melanin content and L value of the skin of the subjects with the coated and uncoated masks were measured, and ITA was calculated as data of "post-treatment" of the skin, and the melanin content, L value and the change rate of ITA were calculated to evaluate the whitening effect of the examples and comparative examples. The results are shown in Table 4, and the appearance of the treated skin is shown in FIG. 6B.

Regarding the melanin content, the L value and the change rate of ITA, the calculation mode is shown as a formula (II):

referring to tables 4, 6A and 6B, wherein table 4 is the result of the aforementioned whitening effect test, and fig. 6A is a photograph of the subject's arm skin after being treated with dihydroxyacetone solution, and fig. 6B is a photograph of the subject's arm skin according to fig. 6A after being coated or uncoated with the compositions of examples 8 to 10 and comparative examples 6 to 7.

TABLE 4 Table 4

From table 4, fig. 6A and fig. 6B, it is shown that: the compositions of examples 8, 9 and 10, to which PEG/PPG/polybutyleneglycol-8/5/3 glycerin (B) was added, had a better whitening effect on the skin of the subject's arm than the compositions of comparative examples 6 and 7, to which no PEG/PPG/polybutyleneglycol-8/5/3 glycerin (B) was added, wherein the whitening effect was more excellent at the 3 weight percent of the use amount of example 8. This shows that PEG/PPG/polybutyleneglycol-8/5/3 glycerin (B) enhances the whitening effect of tranexamic acid (G1-2) and retinol (G2-1) in the composition of the resident facial mask of the present invention.

In summary, by controlling the usage amount of the film forming agent (a) and the weight ratio of the film forming agent (a) to the moisturizing penetrating agent (B), the resident facial mask composition of the present invention can provide good comfort, skin adhesion, stripping easiness and moisturizing effect after being used for a predetermined period of time, and can effectively isolate color cosmetics and prevent adhering pollutants. Furthermore, the peeling mask does not cause skin cutin damage due to good peeling easiness, and the mask can be peeled and the color makeup on the mask can be removed at the same time after a small amount of normal-temperature water is used for wetting the mask. In addition, the composition of the resident facial mask of the invention can enhance the percutaneous permeability of the active additive (G) through the moisturizing penetrating agent (B), thereby helping to improve the efficacy of the active additive (G).

While the present invention has been described with reference to the embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended that the invention be limited only by the terms of the appended claims.
