Description

Water-in-oil type moisturizing cosmetic composition {Cosmetic composition for moisturizing W / O emulsion}

The present invention relates to a water-in-oil type moisturizing cosmetic composition.

Skin is an important organ that plays a variety of physiological functions, such as barrier function, temperature control and excretion, which protect the human body from the external environment and prevent internal moisture and useful components from leaking out. However, as the skin ages due to the following reasons, the physiological function of the skin decreases and the skin condition worsens.

First, the collagen present in the dermal layer of the skin plays an important role in the components of the skin such as mechanical firmness of the skin, resistance of connective tissue, support of tissue adhesion and cell adhesion. Such collagen is reduced by photoaging due to stress, aging or ultraviolet irradiation, resulting in loosening of skin tissue and loss of elasticity.

Second, the cell function of the epidermis is reduced, the metabolic action is not smooth, the exfoliation does not occur well, and when the UV light is excessively accumulated, the elasticity is reduced, causing wrinkles.

Third, when the sebaceous film is not formed on the epidermis, moisture and sebum secretion are reduced and the skin is dried, and wrinkles are formed.

Fourth, oxygen radicals generated in subcutaneous fat destroy cell membranes and cell nuclei, thereby lowering blood circulation, resulting in insufficient nutrition and moisture in the skin, thereby promoting aging.

In order to retard skin aging as described above, excellent cosmetic compositions have been developed. However, most cosmetic compositions are excellent in moisturizing power immediately after application because of the external appearance of water in water type, but the skin moisture film is dried over time and the moisturizing power is lowered.

On the other hand, the water-in-oil type is an oil that has excellent external moisturizing ability immediately after application and maintains excellent moisturizing power by acting as a skin barrier so that the skin oil film does not dry the skin even after a lapse of time. However, the water-in-oil-type cosmetic composition has a monotonous appearance in most opaque forms, compared to the water-in-water type in which various appearances of opacity are different from transparent, and the viscosity or hardness drop over time, resulting in unstable emulsions and oil phases and water phases. Due to the problem of separation, research and commercialization are not progressing much. In addition, the water-in-oil cosmetic composition has a disadvantage in that the feeling of use is poor because the external wound is oil.

Korean Patent Publication No. 10-2007-0071500

In the present invention, 15 to 50 parts by weight of the polyol based on the total weight of the composition; 5 to 30 parts by weight of oil containing silicone oil; And

An oil-in-water cosmetic composition containing 1.0 to 5.0 parts by weight of an emulsifier and having an OD value of 1.0 or less in the visible region may be provided.

The present invention is 15 to 50 parts by weight of polyol based on the total weight of the composition;

5 to 30 parts by weight of oil containing silicone oil; And

An oil-in-water cosmetic composition containing 1.0 to 5.0 parts by weight of an emulsifier and having an OD value of 1.0 or less in the visible light region.

The cosmetic composition of the present invention has an OD value of 1.0 or less in the visible region. In the present invention, the OD value indicates an absorbance value in the visible light region (380 to 780 nm), and the lower the OD value, the higher the transparency. In the present invention, the OD value is 1.0 or less, thereby providing a clear water-in-oil cosmetic composition. The lower limit of the OD value is not particularly limited and may be 0.01 or more.

Hereinafter, the water-in-oil cosmetic composition according to the present invention will be described in more detail.

In the present invention, the polyol is generally used as a moisturizer and is included in the water-in-oil-based cosmetic composition.

As the content ratio increases, the polyol decreases the difference in refractive index with the oil, thereby making the opaque appearance transparent during emulsification.

The polyol is included in an amount of 18 to 60 parts by weight based on the total weight of the aqueous phase.

In addition, the polyol is included in an amount of 15 to 50 parts by weight based on the total weight of the cosmetic composition. If the content of the polyol is less than 15 parts by weight, the water-in-oil type cosmetics are opaque, there is no difference in appearance with the existing products, the viscosity down time is faster in stability over time, there is a fear of low moisturizing persistence When it exceeds 50 parts by weight, the differentiation to the transparent appearance and the moisturizing sustainability are excellent, but there is a possibility that the usability of the product is extremely bad.

Examples of the polyol include glycerin, dipropylene glycol, butylene glycol, pentylene glycol, methylpropanediol, sorbitol, diglycerin, erythritol, pentaerythritol, polybutylene glycol-10, and poly Glycerin-3, Polyglycerin-4, Polyglycerin-6, Polyglycerin-10, Polyglycerin-20, Polyglycerin-40, Sorves-5, Sorves-6, Sorves-20, Sorves-30, Sorbet S-40, inositol, maltitol, maltose, met, mannitol, mannose, lactitol, lactose, dihydroxypropyl PG-glucoside, dithiaoctanediol, fructose, glucamine, methylglucamine, glucose, 1, At least one selected from the group consisting of 2,6-hexanechiol, methylgluses-10, methylgluses-20, ozonized glycerin, phytantriol, thioglycerin, pentitol, trimethylolpropane and ziitol Can be preferably written At least one selected from serine, dipropylene glycol and Butylene Lai colo group consisting may be used.

In the cosmetic composition of the present invention, the oil phase is mainly composed of oil, and the oil has a great influence on the transparency of the water-in-oil cosmetic composition according to the type. In particular, silicone-based oils help improve transparency, and non-silicone-based oils such as esters, hydrocarbons, vegetable oils or fats and oils sharply decrease the transparency and make it opaque.

The oil is included in an amount of 5 to 30 parts by weight based on the total weight of the cosmetic composition.

In the present invention, silicone oil is preferably used as the oil.

As the silicone oil, a conventional silicone oil used in a cosmetic composition may be used, and specifically, a silicone flow fluid or a silicone crosspolymer dispersed in oil may be used.

As the silicone fluid oil, for example, cyclopentasiloxane, cyclohexasiloxane, cycloheptasiloxane, cyclomethicone, cyclophenylmethicone, cyclotetrasiloxane, cyclotrisiloxane, dimethicone, capryldimethicone, caprylyl Trimethicone, caprylylmethicone, cetearylmethicone, hexadecylmethicone, hexylmethicone, laurylmethicone, myrimethylmethicone, phenylmethicone, stearylmethicone, sketchylicmethicone, trifluoro Propylmethicone, cetyldimethicone, dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, methylktrimethicone, phenyltrimethicone and the like can be used. Examples of the crosslinked silicone polymers include cetearyl. Dimethicone Crosspolymer, Cetearyl Dimethicone / Vinyl Dimethicone Crosspolymer, Dimethicone Crosspolymer, Dimethicone Crosspolymer-3, Dimethicone / Py -10 Crosspolymer, Dimethicone / Pig-10-10 / 15 Crosporylmer, Dimethicone / Pig-15 Crosspolymer, Dimethicone / Phenylvinyldimethicone Crosspolymer, Dimethicone / Polyglyceryl-3 Crosspolymer, Dimethicone Chicon / Silsesquioxane Copolymer, Dimethicone / Vinyl Dimethicone Crosspolymer, Dimethicone / Silica Crosspolymer, Diphenyl Dimethicone Crosspolymer, Lauryl Dimethicone Fiji-15 Crosspolymer, Lauryl Dimethicone / Polyglycerin -3 cross polymer and vinyl dimethicone / lauryl dimethicone cross polymer can be used. The silicone oil components may be used alone or in combination of two or more oils.

In the present invention, cyclopentasiloxane or the like can be preferably used.

In the present invention, a mixture of silicone oil and non-silicone oil may be used as the oil.

In order to maintain the transparency that is differentiation of the cosmetic composition to be prepared, the content of the non-silicone oil is preferably 0.5 parts by weight or less with respect to 1 part by weight of the silicone oil. When the non-silicone-based oil is added in excess, the water-in-oil type cosmetics may become opaque or emulsification may not be performed depending on the type of oil, thereby making it difficult to prepare a cosmetic composition.

As the non-silicone oil in the present invention, conventional oils used in cosmetic compositions can be used, and specifically, esters, hydrocarbons, vegetable oils or fats and oils can be used.

Examples of the esters include ascorbyl palmitate, ascorbyl oleate, ascorbyl stearate, distearyl maleate, benzyl benzoate, benzyl laurate, butylene glycol dicaprylate / dicaprate, butylene glycol diisononanoate , Butylene glycol laurate, butylene glycol stearate, butyl isostearate, cetearyl isonanoate, cetearyl nonanoate, cetyl caprylate, cetylethylhexanoate, cetyl isononanoate, Ethylhexyl caprylate / caprate, ethylhexyl isononanoate, ethylhexyl isostearate, ethyl hexyl laurate, hexyl laurate, octyldodecyl isostearate, isopropyl isostearate, isostearyl Isononanoate, isostearyl isostearate, isocetylethylhexanoate, neopentylglycol dicaprate, neo Tyl glycol diethyl hexanoate, neopentyl glycol diisononanoate, neopentyl glycol diisostearate, pentaerythritol stearate, pentaerythritol tetraethylhexanoate, triethylhexanoin and the like can be used. Examples of the oil include liquid paraffin (liquid paraffin, mineral oil), paraffin, petrolatum, microcrystalline wax and squalane, and vegetable oils include avocado oil, wheat germ oil, rosehip oil, shea butter and almond oil. , Olive oil, castor oil, camellia oil, corn oil, safflower oil, soybean oil, rapeseed oil, macadamia nut oil, jojoba oil, cacao butter, palm oil, palm kernel oil and coconut oil can be used.

The aforementioned non-silicone oil components may be used alone or in combination of two or more oils.

In the cosmetic composition of the present invention, the emulsifier has a great influence on the size of the emulsified particles, the stability of the emulsion, the feeling of use and the transparency of the appearance depending on the type and content thereof.

The emulsifier is included in an amount of 1.0 to 5.0 parts by weight based on the total weight of the cosmetic composition. If the content is less than 1.0 parts by weight, the transparency of the appearance becomes more and more, but there is a concern that separation of the aqueous phase and the oil phase occurs in the stability over time, and if it exceeds 5.0 parts by weight, the transparency of the appearance is degraded and there is a possibility that the feeling of use is greatly worsened.

In the present invention, one or more synthetic surfactants or natural surfactants such as anionic surfactants, cationic surfactants, amphoteric surfactants and nonionic surfactants may be used as emulsifiers. In the present invention, it is preferable to use nonionic surfactants, in particular silicone surfactants.

Such materials are polydimethyl siloxanes modified to include polyether side chains such as polyethylene oxide chains, polypropylene oxide chains, mixtures of such chains, and polyether chains comprising moieties derived from both ethylene oxide and propylene oxide. . In addition, as another example of the silicone-based surfactant, it is possible to use an alkyl-modified dimethicone copolyol, i.e. a compound comprising a C2-C30 pendant side chain.

Non-limiting examples of dimethicone copolyols useful as surfactants in the present invention include lauryl dimethicone copolyol, lauryl polydimethylsiloxyethyl dimethicone copolyol, dimethicone copolyol acetate, dimethicone copolyol adipate, Dimethicone copolyolamine, dimethicone copolyol behenate, dimethicone copolyol butylether, dimethicone copolyol hydroxy stearate, dimethicone copolyol isostearate, dimethicone copolyol laurate, dimethicone copolyol methyl ether , Dimethicone copolyol phosphate and dimethicone copolyol stearate can be used.

Hereinafter, embodiments of the present invention will be described in detail to facilitate understanding of the present invention. However, the embodiments according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following embodiments. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art.

Examples 1-2 and Comparative Examples 1-3

The cosmetic compositions of Examples 1 to 2 and Comparative Examples 1 to 3 were prepared by the following methods using the compositional components and contents (parts by weight) shown in Table 1 below.

First, the oil phase part measured the raw materials 1 to 3 and warmed up to 75 ° C., uniformly mixed in a homo mixer, and slowly added small amounts of raw materials 4 to uniformly disperse them in the homo mixer.

The water phase portion was weighed from 5 to 10 of the raw material, warmed up to 75 ° C, uniformly mixed with a disper, and then emulsified while slowly introducing the water phase portion into the oil phase portion. The emulsification was performed at 5000 rpm, 75 ° C. and 10 minutes with a homomixer, and after the emulsification was completed, the mixture was gradually cooled and infused at 50 ° C. to completely disperse with a homomixer, followed by defoaming to obtain a cosmetic composition for improving skin condition. Prepared.

Although the cosmetic composition was manufactured with the above-mentioned ingredients and contents, in Comparative Example 3, the emulsion was not properly formed during emulsification, and separation of the oil phase and the water phase occurred, and thus a sample (cosmetic composition) could not be obtained. This is because when the non-silicone oil is more than 0.5 parts by weight relative to 1 part by weight of the silicone oil during production, it is not possible to form a stable emulsion.

Experimental Example 1. Evaluation of transparency

In order to evaluate and evaluate the transparency of the cosmetic compositions of Examples 1 to 2, Comparative Examples 1 to 2 and Comparative Example 4, the optical density in the visible region (380 nm-780 nm) was measured. The measurement device used a SpectraMax 190 instrument from Molecular Devices, Inc., and the results are shown in FIG. 1.

The transparency of the cosmetic composition becomes opaque as the OD value is 1 or less, the lower the value, the higher the transparency, and the higher the value of 1 or more, the lower the transparency.

As shown in FIG. 1, Examples 1 to 2 exhibit low OD values in the visible light region and high transparency, whereas Comparative Examples 1 and 4 exhibit high OD values in the visible light region and form an opaque water-in-oil emulsion. It can be seen. In the case of Comparative Example 2 using an excessive amount of polyol, the transparency has an excellent value, but the feeling is not good (see Experimental Example 4), it is difficult to commercialize.

Experimental Example 2. Evaluation of Water Retention Capacity

In order to evaluate the moisturizing power of the cosmetic compositions of Examples 1 to 2 and Comparative Example 4, a method of quantitatively applying the cosmetic composition to the skin and then evaluating moisture retention capacity was used. The equipment used at this time is a skin moisture content measuring device (Skicon 200 (IBS, high frequency: 3.5MHz)) to measure the electrical conductivity of the skin to measure the moisture content of thin skin (corresponding to the keratinocyte layer). The composition of Examples 1 and 2 and Comparative Example 4 was applied to the inside of the arm of 15 test subjects in a constant temperature and humidity room of 22 ° C. and a relative humidity of 50%, and then rubbed well. Short-term effects were evaluated by measuring the percentage of water growth (%) after 1 hour and 3 hours based on the moisture retention capacity, and the three-day moisturizing effect was measured to evaluate the cumulative applied moisture retention capacity. After applying the cosmetic composition twice a day, taking a shower and measuring the rate of water growth the next day, it was again carried out for three days in the process of applying the cosmetic composition again, the results obtained are shown in Table 2 below.

(Moisture retention unit:%) division 1 hour immediately 3 hours immediately After 1 day Two days later 3 days later Example 1 21.60 20.81 19.22 26.38 30.75 Example 2 24.36 24.18 22.67 28.25 33.46 Comparative Example 4 13.45 12.89 11.51 14.25 16.32

As shown in Table 2, when comparing the cosmetic composition of Examples 1 and 2 with the water holding capacity of the general oil-in-water cosmetic composition (Comparative Example 4), the increase rate of water retention of 1 hour immediately after and 3 hours after the very high, When the cumulative application to the skin for three days was confirmed that the increase in moisture retention is greater. This indicates that the skin moisturizing effect by accumulation is greater.

Experimental Example 3. Evaluation of Moisture Evaporation

Evaluation of the water evaporation amount of the cosmetic composition prepared according to Examples 1 to 2 and Comparative Example 4. The test method is to apply a predetermined amount (2mg / cm ² ) to the inside of the arm of 15 subjects in a constant temperature and humidity room of 22 ℃, 50% relative humidity, and then rub well, using a water evaporation meter at intervals of 2 minutes for 10 minutes The amount of water evaporation of the skin was measured. And cosmetics

 The amount of water evaporation over three days was measured to determine the cumulative effect of using the composition. After applying the cosmetic composition twice a day, taking a shower, the next day was carried out for three days by measuring the amount of water evaporation for 10 minutes before and after applying the cosmetic composition. The results obtained at this time are shown in Table 3 below.

In addition, at the end of the test separately, the test subjects were asked to fill out a questionnaire and subjected to mechanical evaluation and subjective efficacy evaluation, and the results are shown in Table 4 below.

(Moisture evaporation unit:%) division Water evaporation after 10 minutes Moisture evaporation after 1 day Water evaporation after 2 days Water evaporation after 3 days Example 1 15.32 16.24 14.85 13.43 Example 2 14.98 15.74 13.25 13.46 Comparative Example 4 38.26 39.72 38.16 37.28

division Respondents Very good Great Inadequate Very poor Example 1 3 10 2 0 Example 2 5 8 One 0 Comparative Example 4 0 3 8 4

As shown in Table 3, Examples 1 and 2 of the water-in-oil type according to the present invention can be seen that the amount of water increase is greatly lowered when comparing the water evaporation amount with Comparative Example 4 of the general water-in-water type. This is because the trauma acts to prevent the volatilization of water by forming an oil film on the skin. In addition, as shown in the skin drying improvement effect survey of Table 4, it can be confirmed that the cosmetic composition of the embodiment has a great effect in improving skin dryness by maintaining skin moisture by preventing volatilization of water.

Experimental Example 4. Evaluation of Customer Satisfaction

After dividing 40 women from 25 to 45 years into two groups, Examples 1 to 2 and Comparative Examples 1, 2, and 4 were appropriately adjusted to each group to be used on both sides of the face, and according to the following evaluation criteria, adhesion and moisturizing power And customer satisfaction such as overall feeling of use and skin condition improvement. The results are shown in Table 5 below.

<Evaluation Criteria>
