Description

Mascara composition having low specific gravity}

The present invention relates to a mascara composition used for eyelash makeup.

Mascara, which is generally applied to eyelashes, is intended to curl eyelashes longer and add volume, making the eyes look larger and clearer. Since this type of mascara is applied to the eyelashes, it can be easily erased by blinking or tears, and does not last long even if curled when applied.

Accordingly, the demand for curling and color retention was very high, and the demand for oil-dispersed type mascara, in which wax, powder, and film formers were dispersed in oil with excellent curl retention, increased.

However, the existing oil-dispersed type mascara uses a high-content plate-shaped powder packing system to achieve fast drying speed and initial curling power, but as this formulation contains a high content of powder, the body increases, so the contents clump together on the eyelashes and cleanse. There was this difficult problem.

Below, the present invention will be described in detail with reference to the attached technology so that those skilled in the art can easily practice it. However, it will be apparent to those skilled in the art that the present invention can be implemented in various different forms and is not limited to the embodiments described below.

The present invention relates to a low-specific gravity mascara composition that has good volume but low body, so it has good curling durability, less clumping, and allows for clean cleansing. By lowering the specific gravity of the composition, there is no sagging compared to the eyelash volume, thereby improving the curling durability of eyelashes. The biggest characteristic is that it is ordered. The mascara composition of the present invention includes an oil phase, powder, a film former, and fiber, and the oil phase includes oil, wax, and an oil thickener, and the oil phase thickener is Dextrin Palmitate. , Dextrin Palmitate/Ethylhexanoate, and Hydrogenated Styrene/Isoprene Copolymer.

The oil phase thickener of the present invention is a raw material contained in the oil phase to increase the viscosity of the formulation. The cosmetic composition of the present invention contains dextrin palmitate, dextrin palmitate/ethylhexanoate, and hydrogenated styrene/isoprene in the oil phase. It is characterized in that copolymers are mixed and used. Specifically, the present invention can produce a composition with low specific gravity and achieve the above-mentioned effects by mixing and using the three thickeners above in the oil phase.

As an embodiment of the present invention, based on the total weight of the composition, the dextrin palmitate is 0.01 to 10% by weight, the dextrin palmitate/ethylhexanoate is 0.01 to 10% by weight, and the hydrogenated styrene/a. Isoprene copolymer may be included in an amount of 0.01 to 10% by weight. Preferably, the dextrin palmitate may be included in an amount of 0.01 to 1% by weight, the dextrin palmitate/ethylhexanoate may be included in an amount of 0.01 to 5% by weight, and the hydrogenated styrene/isoprene copolymer may be included in an amount of 0.01 to 5% by weight. there is. If each thickener exceeds the above range or the total sum exceeds 30% by weight, the viscosity of the oil phase is high, which may lead to difficulties in manufacturing and problems in forming and maintaining formulation stability.

As an embodiment of the present invention, a separate oil thickener may be additionally included in addition to the dextrin palmitate, dextrin palmitate/ethylhexanoate, and hydrogenated styrene/isoprene copolymer. For example, Dibutyl Lauroyl Glutamide, Dibutyl Ethylhexanoyl Glutamide, Polyamide-8, Polyamide-3 , Hydroxystearic Acid, Disteardimonium Hectorite, Bentonite, Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer, Glycein One or more types selected from the group consisting of Glyceryl Tribehenate/Isostearate/Eicosandioate, Dextrin Myristate, and Stearoyl Inulin may be used. There is no limitation to the above-mentioned raw materials as long as they are used to thicken the oil phase.

In the composition of the present invention, the total thickener, that is, the total thickener including the oil thickener additionally included in addition to the dextrin palmitate, dextrin palmitate/ethylhexanoate, and hydrogenated styrene/isoprene copolymer , It may contain 7 to 37% by weight based on the total weight of the composition, and preferably 12% to 15% by weight. If it exceeds the above range, the viscosity of the oil phase is high, making manufacturing difficult and the feeling of use is poor, and if it is below the above range, there may be problems maintaining formulation stability.

The cosmetic composition of the present invention includes an oil phase, a film former, fiber, and powder. In the present invention, the powder is preferably included in an amount of 1 to 15% by weight based on the total weight of the composition. If it is less than 1% by weight, the blackness is too low or there is a problem in maintaining formulation stability, and if it is more than 15%, the viscosity increases, causing problems in formulation stability and poor feeling of use, which can cause problems such as smearing and powdering.

As an example, the powder of the composition of the present invention includes titanium dioxide, zinc oxide, polymethyl silsesquioxane, polymethyl methacrylate, talc, It may be one or more selected from the group consisting of Mica, Alumina, Barium Sulfate, Perlite, Kaolin, Magnesium Myristate, or Iron Oxie. Also, coated powder can be used. It is not limited to the types of powders described above, and of course, those skilled in the art can appropriately include them according to the properties of the contents such as curling power, fixation power, volume, and spreadability.

In addition, the composition of the present invention includes an oil phase and a powder, and in the present invention, the oil phase is preferably included in an amount of 60 to 93% by weight based on the total weight of the composition.

As described above, in the present invention, the oil phase may include oil, wax, and an oil phase thickener.

The oil that can be included in the composition of the present invention may be one or more of ester-based, triglyceride-based, and hydrocarbon-based oils, and is included in an amount of 40 to 80% by weight based on the total weight of the composition. It is desirable. If the oil is less than 40% by weight, the compatibility between compositions is lowered or the flowability is poor, so there is a problem with dispersibility. If the oil is more than 55% by weight, the thickening effect is low and hardness is not formed, making it difficult to make a solid product, and the content of the oil portion is low. If this is too high, there is a problem of sweating, which causes oil to exude from the cosmetic when the external temperature changes.

As an embodiment, the ester oil includes Neopentyl Glycol Diheptanoate, Butylene Glycol Dicaprylate/Dicaprate, Diisosteryl Malate, Isopropyl Myristate, Isopropyl Palmitate, Octyldodecyl Myristate, Cetyl Ethylhexanoate, Isopropyl Stearate, Triethyl Hexa Triethylhexanoin, Diethoxyethyl Succinate, Isostearyl Isostearate, Isostearyl Isononanoate, Alkyl Benzoate and Pentaerythrityl It may be one or more selected from the group consisting of tetraisostearate (Pentaerythrityl Tetraisostearate), but is not limited thereto. The triglyceride oil includes caprylic/capric triglyceride, caprylic/capric/stearic triglyceride, triethyloctanoin, and triglyceride. It may be one or more selected from the group consisting of caprylin (tricaprylin), but is not limited thereto. In addition, the hydrocarbon oil is selected from the group consisting of polybutene, isohexadecane, isododecane, hydrogenated polyisobutene, and vegetable squalane. There may be more than one, but is not limited thereto. The above oils can be mixed and used by adjusting the appropriate ratio depending on the product's spreadability (softness, moisture, adhesion, etc.). Additionally, for the purpose of usability, silicone oil, vegetable oil, etc. may be additionally used in addition to the types of oils described above.

The wax that may be included in the oily part of the present invention forms a film when the mascara composition dries and serves to thicken the contents. If an excessive amount of such wax is included, the body of the contents increases and the hardness increases excessively, causing the contents to dry out or become hard. This poses a problem in maintaining the stability or properties of the formulation. The present invention contains 5 to 20% by weight of the wax based on the total weight of the composition, and while including the wax in the composition, the dextrin palmitate, dextrin palmitate/ethylhexanoate, and hydrogenated styrene/isoprenco By using a thickener mixed with a polymer, the mascara composition can have sufficient viscosity and have a low body with low specific gravity, thereby improving curling durability.

The wax that can be included in the present invention is not particularly limited as long as it is a solid oil commonly used in cosmetics, and may be one or more selected from the group consisting of hydrocarbon-based, ester-based, higher alcohol-based, silicone-based, and vegetable-based solid oils. Specifically, hydrocarbons such as petrolatum, paraffin wax, microcrystalline wax, and polyethylene, plant-derived oils such as hydrogenated castor oil, hydrogenated jojoba oil, carnauba wax, and rice wax, glyceryl tribehenate, cholesterol fatty acid ester, etc. One or more of esters, higher fatty acids such as stearic acid and behenic acid, higher alcohols such as stearyl alcohol and behenyl alcohol, and silicones such as alkyl-modified silicone and acrylic-modified silicone may be used.

Meanwhile, the present invention may additionally include a film former (film former). This film former is preferably contained in an amount of 5 to 25% by weight based on the total weight of the composition. If the content of the film former is less than 5%, the film forming effect is low and the effect of improving sustainability is minimal, and if it exceeds 25%, a sticky feeling occurs and spreadability is poor.

The film forming agent that may be included in the present invention may be one or more selected from the group consisting of trimethylsiloxysilicate, polypropylsilsesquioxane, and cyclopentasiloxane, but is not limited thereto. No.

The cosmetic composition of the present invention includes an oil phase, powder, a film former, and fiber, and the fiber of the present invention may be included in an amount of 0.5 to 1% by weight based on the total weight of the composition.

Meanwhile, the mascara composition according to the present invention may be manufactured in an oil dispersion type.

Additionally, from the standpoint of those skilled in the art, any additional ingredient and/or amount thereof may be selected and added within a range such that the advantageous properties of the composition of the present invention are not substantially affected. For example, moisturizing ingredients such as vegetable oil, additives such as adenosine or oil-soluble licorice extract, other colorants, fragrances, fillers, preservatives, preservatives, neutralizers, sunscreens, sweeteners, vitamins, free-radical scavengers, metal ion sequestrants, and mixtures thereof. In particular, the oil phase may additionally contain other auxiliary emulsifiers, preservatives, antibacterial agents, etc.

The mascara compositions of Examples 1 to 2 and Comparative Examples 1 to 4 prepared according to the above-described method were subjected to sensory evaluation. Twenty women aged 20 to 40 were asked to rate curling power, curl holding power, amount of application, spreadability, drying speed, and ease of cleansing on a scale of 1 to 10. Curling power is an evaluation of the degree of curling upon initial application, and curl holding power is a sensory evaluation of the sustainability of curling. In addition, the application amount evaluates the amount of content spread on the eyelashes when applied per application, the spreadability evaluates the extent to which it is applied neatly and lightly without clumping, and the cleansing refers to the amount of content applied to the eyelashes when applied per application. This was evaluated to see whether it can be easily erased and leaves no powder behind. The evaluation results are shown in Table 2 below. A score of 8 or more is indicated as very good, a score of 6 to 8 is indicated as good, a score of 3 to 6 is indicated as average, and a score of less than 3 points is indicated as poor.

(●; Very good, ○; Good, △; Average, X; Poor)

As can be seen in Table 2, the mascara composition containing hydrogenated styrene/isoprene copolymer (raw material 3) is the mascara composition not containing hydrogenated styrene/isoprene copolymer (Comparative Example 1) When compared with , it was found that it applied lightly without clumping and was easy to cleanse without powdering or hardening.

In particular, curling power, curl fixing power, spreadability, and cleansing were improved in compositions containing 0.01 to 5% by weight of hydrogenated styrene/isoprene copolymer. In addition, in the composition containing 4 to 6% by weight of hydrogenated styrene/isoprene copolymer (Example 2), the curling power and curl fixing power were less effective compared to Example 1, but it was confirmed that spreadability and cleansing were improved. I was able to. However, in compositions containing more than 6% by weight of hydrogenated styrene/isoprene copolymer, the formulation swelled too lightly and gelled, pushing the contents and slowing drying, resulting in a decrease in curling power and curl fixing power.

As can be seen in Table 4, when compared to the mascara composition containing dextrin palmitate/ethylhexanoate (raw material 5) with the mascara composition not containing dextrin palmitate/ethylhexanoate (Comparative Example 5), It was seen that the amount applied per time increased and that the curling power, curl holding power, and spreadability were good. In particular, when containing 2.5% by weight of hydrogenated styrene/isoprene copolymer, the curling power, curl fixing power, and spreadability were most improved in the composition containing 0.01 to 5% by weight of dextrin palmitate/ethylhexanoate. Even when compared to Example 1, the feeling of use (application amount and spreadability) of Example 3 was better. In addition, in the composition containing 5% by weight of dextrin palmitate/ethylhexanoate (Example 4), the drying speed was lower than that of Example 3, but it was confirmed that the curling and curl fixing power were more effective than the comparative examples. .

On the other hand, in compositions containing more than 7% by weight of dextrin palmitate/ethylhexanoate, the curling power and curl fixing power are reduced, and the stability of the formulation is unstable due to excessive thickening, the application amount is reduced, and the application becomes rough and lumpy. I was able to confirm.
