Long lash mascara composition with excellent durability}

The present invention relates to a long-lasting mascara composition excellent in persistence, and more specifically, a high molecular weight polyethylene glycol polymer having a stretching effect and a polyacrylate polymer having excellent fixing strength are mixed and used at an optimum ratio, and citric acid By further containing an ester plasticizer, the present invention relates to a long lash mascara composition having excellent long lashing power and excellent durability without falling off phenomenon.

In general, mascara's functions are divided into volume, curling, long lash and waterproof. Among them, Asian women have a tendency to prefer long-lashing function because they have less thinning and shorter eyelashes than Western women. In mascara, "long lash" means that the eyelashes are made longer than the original state, and many methods have been developed to give such a long lash.

As such, the technology for increasing the long lashing power has been developed to attach the fiber to the eyelashes using a large amount of materials such as synthetic nylon, rayon or polyvinyl fiber, and to improve the volume and make it look long using adhesive powder. Mascara is continuously being developed to further enhance the effects of long-lashing power by applying these two technologies individually or in combination.

Another consideration for women using mascara is makeup sustainability. Most women use mascara on busy mornings and cannot make corrections afterwards, so make sure to keep their original makeup until they are removed. However, mascara using fiber is widely used because it can stick to eyelashes for a long time due to its morphological characteristics, which can give an immediate long lash improvement effect.However, when a large amount of fiber or powder is used, the contact area with the eyelashes is small. As a result, disadvantages such as powder falling off and clumping from the eyelashes appear again, and the powder falling may cause eye irritation when foreign substances enter the eyes.

Therefore, conventional long lash mascara manufacturing techniques using components such as fiber and powder have a limit in satisfying excellent long lashing power and durability at the same time.

In general, plasticizers have strong pulling forces between molecules, so that they are interposed between hard polymers and weaken the direct pulling force between molecules to make the polymers bend well. compatibility). Plasticizers include DOP (dioctyl phthalate), DOA (dioctyl adipate) and TCP (tricresyl postate), but DOP is a hazardous substance and is not suitable for use in cosmetics. Therefore, cosmetics use a small amount of silicone oil or polyol as a material that acts as a safe plasticizer for the human body, but mascara or eye makeup causes eye smears when such silicone oil is used. Therefore, in the manufacture of mascara and eye makeup, there is a need for a plasticizer that is safe for the human body and prevents eye bleeding.

Accordingly, the present inventors have studied to prevent problems such as sagging or falling of the stretched polymer over time while being fast fixed while improving the long lashing power of mascara. By mixing the polymer and the polyacrylate polymer with excellent fixing force at the optimum ratio, and using the oil-soluble plasticizer in addition, the long-lasting mascara with excellent persistence is improved by improving the long lashing power of mascara and solving the problem of eyebrow sagging and powder falling out. It has been found that the present invention has been completed.

Accordingly, an object of the present invention is to provide a long lash mascara composition excellent in durability.

In order to achieve the above object, in the present invention, a high molecular weight polyethylene glycol polymer and a polyacrylate polymer having an average molecular weight of 600,000 to 4,000,000 are contained in a weight ratio of 1: 3 to 3: 1, and citric acid ester-based It provides a long lash mascara composition further containing a plasticizer.

The mascara composition of the present invention has excellent long lashing power and no powder fall off, and has good applicability, so it meets the needs of various people, such as those who have short eyebrow length, those who prefer long lash mascara, and those who prefer smooth and smooth mascara. I could make it.

Hereinafter, the present invention will be described more specifically.

The present invention relates to a long lash mascara composition containing a high molecular weight polyethylene glycol polymer having a stretching effect and a polyacrylate polymer having excellent fixing ability.

Generally, polyethylene glycol polymers are hardly used in mascara compositions for the purpose of improving the sustainability and curling ability because of low fixation force and film-forming ability. However, in the present invention, the polyethylene glycol polymer has a smooth and naturally sagging property. In order to make use of the advantages of the polymer and to compensate for the disadvantage, it was used by mixing it with a specific ratio with a polyacrylate polymer having excellent fixing ability.

In addition, in the present invention, in order to find a polyethylene glycol-based polymer having excellent stretching effect, polymers generally used in cosmetics are contained in the same base in the same amount and applied to the eyelashes, and only polymers having a length change of 20% or more before and after application are selected. . Specific examples of such polyethyleneglycol polymer include polyethyleneglycol-14M, polyethyleneglycol-90M or sodium polyacrylate, and it is preferable to use a high molecular weight polyethyleneglycol polymer having an average molecular weight of 600,000 to 4,000,000. Commercially available high molecular weight polyethylene glycol polymers include, for example, Amerchol's Polyox WSR series (205,301), LCW's covacryl AC, covacryl J22, Cognis's cosmedia SP, BASF's Hysorb 8200, and the like. Polyethylene glycol or sodium polyacrylate used in the present invention has a strong polarity between polymer molecules because of the strong oxygen between the repeating unit (repeating unit) has a property that stretches as the molecular weight increases, in particular polyethylene glycol is generally However, even if the molecular weight increases, it does not harden and has a soft property, and when applied to mascara, the applicability is excellent. In addition, when the high molecular weight polyethylene glycol polymer having an average molecular weight of 600,000 ~ 4,000,000 is used, the long lashing force is improved because the stretching effect is better when dissolved in water than the low molecular weight polyethylene glycol polymer. The long lash effect according to the molecular weight of polyethylene glycol can be confirmed through the following Examples and Comparative Examples.

As the polyacrylate polymer having excellent fixation force used in the present invention, among the polymers used for fixing hair to hair gels, mousses, waxes, and sprays, short eyelashes can be fixed quickly and polymers without eye irritation and non-stickiness can be selected and used. have. Such polymers include, for example, aminomethylpropanol-acrylate and polyacrylates, for example polyurethane-14 and aminomethylpropanol-acrylate copolymers, aminomethylpropanol-acrylate / arylmethacrylate copolymers and polyacrylates. Late 2-cross polymers and polyacrylate-14 and the like, and among these, polyurethane-14 and aminomethylpropanol-acrylate copolymers are most preferably used. These polyacrylate-based polymers are manufactured and marketed in a variety of viscosities and molecular weights. Examples of commercially available products include, for example, Dynam X from National starch & chemical, G-100 Polymer, Super hold Polymer and Plus, a fixate series from Noveon. Polymer and the like.

The long lash mascara composition according to the present invention may contain a polymer mixture of the polyethyleneglycol polymer and the polyacrylate polymer in an amount of 0.1 to 20% by weight, and most preferably 3 to 10% by weight, based on the total weight of the composition. It is contained in%. If it is used less than 0.1% by weight, there is no long lash effect, when used in excess of 20% by weight the viscosity is increased, the uniform mixing is not achieved. In this case, the optimum mixing ratio of the polyethylene glycol polymer and the polyacrylate polymer is preferably 1: 3 to 3: 1 by weight. When the content of the polyethylene glycol polymer is less than the above ratio, there is no agglomeration phenomenon, but there is no good feeling in long lashing force, whereas when the content of the polyethylene glycol polymer is higher than the ratio, the long lashing force is excellent but the aggregation phenomenon may be severe. .

In addition, the long lash mascara composition according to the present invention may further contain an oil-soluble plasticizer in order to provide long lashing power and durability at the same time. In the present invention, acetyltributylcitrate or acetyltrihexylcitrate, which is a citric acid ester plasticizer, is used in order to be safe for the human body and to prevent eye bleeding. These plasticizers are commercially available from Morflex's Citroflex A-4 and Citroflex A-6. The long lash mascara composition according to the present invention contains the citric acid ester plasticizer in an amount of 0.1 to 10% by weight based on the total weight of the composition, thereby preventing flaking and powdering of the long lashing eyebrow surface. If the content of the plasticizer is less than 0.1% by weight, too small amount can not be expected to improve the sustainability, if the content exceeds 10% by weight lowering the physical properties of the polymer giving the fixing force rather weak durability due to sagging eyebrows.

Long lash mascara composition according to the present invention can be easily selected by those skilled in the art other additives commonly used in the manufacture of mascara in addition to the above components.

Hereinafter, the content of the present invention will be described in more detail through examples and test examples. These examples are provided only for understanding the contents of the present invention, and the scope of the present invention is not limited to these examples, and modifications, substitutions, and insertions commonly known in the art may be performed. This is also included in the scope of the present invention.

As can be seen from the results of Table 2, the mascaras prepared in Examples 1 to 3 and Comparative Examples 1 and 3 were all excellent in long lashing power, but in the case of Comparative Example 2 the molecular weight of the polyethylene glycol used I couldn't get the stretching effect, so I could see that the longlash function was falling. In addition, in evaluation of the spreadability, powder fall, agglomeration and persistence, Examples 1 to 3 and Comparative Example 2 were superior to Comparative Example 1, and Example 3 and Comparative Example 2 including the oil-soluble plasticizer showed almost no powder falling phenomenon. Did. In Comparative Example 3, although the powder contained a plasticizer, the powder falling phenomenon and the persistence resulted in a weak result, which is that the long-lashing mascara liquid dropped out over time because the stretching ratio was large compared to the polymer ratio fixed by the polymer ratio. Because.

Test Example 2 Long Lashing Force (Eyebrow Length Before and After Application) Measurement

In order to numerically compare the long lashing power of Examples 1 to 3 and Comparative Examples 1 to 3, the change of the eyebrow length after each mascara was measured according to the following method, and the results are shown in Table 3 below.

First, after measuring the length before the application of the false eyelashes, the mascara was applied 36 times and completely dried, and then the length of the false eyelashes was measured, and the length of the eyebrows before the application was removed from the eyebrow length after applying the mascara as described in Equation 1 below.

Eyebrow length change = (eyebrow length after mascara application)-(eyebrow length before mascara application)

Test Items Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Eyebrow length change amount (㎛)

As shown in the results of Table 3, when comparing only the long lashing force Comparative Example 1, 3 and Examples 1 to 3 except for Comparative Example 2 using a low molecular weight polyethylene glycol was confirmed that the long lashing force is excellent once again, This is consistent with the sensory evaluation results of Test Example 1.

Test Example 3 Powder Falling Measurement

In order to compare the powder falling phenomenon of Examples 1 to 3 and Comparative Examples 1 to 3, the degree of powder falling was measured according to the following method, and the results are shown in Table 4.

After applying a certain amount of mascara of 1 to 3 and Comparative Examples 1 to 3 on the false eyelashes, completely dried them, covering 10 × 10 paper on the false eyelashes, applying a constant weight force (repeated 3 times with a 5 kg roulette) ) Was observed on the paper. After that, the state of false eyelashes was observed. In mascara applied to false eyelashes, less than 5% of the total application area was good, good if less than 10% was attached to paper, normal if 10-20% was attached to paper, and bad if more than 20% was attached to paper. .
