Description

Mascara composition with improved smudging {Macara composition that solves the smudge problem}

The present invention relates to a mascara composition with improved smearing, and more specifically, a mascara composition containing an alkyl phosphate neutralized with an alkali agent stably maintains a multilayer structure similar to that of a phospholipid, so that the mascara is resistant to sweat, tears and oil. It relates to a mascara composition that reduces the phenomenon of smearing.

Mascara is applied to the eyelashes and is used to emphasize the contours of the eyes and to give beauty to the eyes. In mascara, voluminous means that the eyelashes are thicker than their original state, making them thicker and richer.

However, in general, volume mascara has a problem that it spreads easily through sweat, tears and oil due to the large amount of application, and when the relatively soft wax (microcrystalline wax, paraffin wax, etc.) used for volume mascara causes the phenomenon of smearing under the eyes there are many

In order to improve such under-eye smearing, a solution method of replacing a hard wax with a high melting point or applying an excessive amount of a film forming agent is used, but this causes disadvantages in that the spreadability and volume effect may be reduced.

Accordingly, it is necessary to develop a volume mascara formulation that can improve smearing under the eyes without bad application.

One object of the present invention is to provide a mascara composition comprising an alkylphosphate neutralized with an alkali agent.

This will be described in detail as follows. Meanwhile, each description and embodiment disclosed in the present invention may be applied to each other description and embodiment. That is, all combinations of the various elements disclosed herein fall within the scope of the present invention. In addition, it cannot be considered that the scope of the present invention is limited by the specific descriptions described below.

One aspect of the present invention for achieving the above object, it provides a mascara composition comprising an alkyl phosphate neutralized with an alkali agent.

Specifically, in the mascara composition, the alkyl phosphate neutralized with an alkali agent provides a multi-layered structure and contains an oil-in-water emulsifier in the multi-layered structure to prevent the oil component from being desorbed, so that the formulation of the mascara composition has stability, spreadability, hardness, and eyesight. It can provide the effect of improving the smearing underneath.

As used herein, the term "alkaline agent" helps the reducing agent to function, and specifically, the alkali agent swells the hair so that the mascara composition can penetrate into the hair. For the purpose of the present invention, it serves to neutralize the alkyl phosphate, and serves to use it as an emulsifier.

The molecular weight of the alkali agent may be 125 g/mol to 250 g/mol.

Specifically, when the molecular weight is less than 125 g/mol, the interfacial structure is not relatively hard, and thus a smearing phenomenon may occur. When the molecular weight exceeds 250 g/mol, hardness may be improved and the feeling of use may deteriorate.

Specifically, the alkali agent may be ammonia, alkanol amines, organic amines, basic amino acids, or salts thereof, but is not limited thereto.

More specifically, the alkaline agent may include arginine or triethanolamine, but is not limited thereto.

As used herein, the term "alkylphosphate" is an ester of phosphoric acid and an aliphatic alcohol, trialkylester PO(OR) ₃ , dialkylester PO(OR) ₂ OH, monoalkyl ester PO(OR)(OH) ₂ Three types are known. Higher means that it can be used as an anionic activator and can be used for stabilization in a mascara composition.

Specifically, the alkyl of the alkyl phosphate may be in a saturated or unsaturated state, and the alkyl may be linear or branched, but is not limited thereto.

Specifically, alkyl may be unsaturated and saturated, for example, methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl, octyl, nonyl, decyl, lauryl, myristyl, cetyl, stearyl, behenyl, etc. alkyl groups and may include, but are not limited to, ethenyl, propenyl, butenyl, pentenyl, hexenyl, octenyl, nonenyl, decinyl, oleyl, eicosinyl.

More specifically, the alkyl phosphate may include, but is not limited to, cetyl phosphate.

The alkyl phosphate neutralized with the alkali agent may be used as an emulsifier.

As used herein, the term "emulsifier" refers to a so-called surface active substance that contains both hydrophilic and lipophilic groups in the molecule and thus is easy to form an adsorption layer at the interface between water and oil, and is used to increase the viscosity or thicken the composition. , means that it can be used for a purpose to solve the problem of forming a heavy and thick wax coating film on the eyelashes due to the use of wax, etc. and the problem with the change of composition over time.

The alkyl phosphate neutralized with the alkali agent may form a multi-layered structure, and may include an oil-in-water emulsifier (O/W emulsion) between the multi-layered phases.

Specifically, the alkyl phosphate is neutralized with an alkali agent having a relatively bulky structure and used as the main emulsifier, and the neutralized alkyl phosphate forms a multi-layered structure in a form similar to phospholipids, thereby strengthening the interface of the emulsified particles. In addition, according to the multi-layered structure, it is possible to prevent the increase in hardness and gelation and to maintain the hardness, which improves the stability of the formulation, and prevents the inner wax from melting by sweat, tears and oil, thereby improving the smearing phenomenon under the eyes. It can provide the effect of improving the application properties and the spreadability of the formulation.

In a specific embodiment, the composition of the present invention contains an oil-in-water emulsifier in the multi-layered structure to solve the problem of causing the mascara to spread under the eyes as the oil component is detached to the outside by including the oil-in-water emulsifier in the conventional single-layer structure. Thus, the effect of preventing the oil component from being desorbed and improving the smearing under the eyes was confirmed.

More specifically, in forming a multi-layered structure, structural differences may occur depending on the type of alkali agent. As shown in (b) of Figure 2, when an organic alkali agent having a higher molecular weight than in Figure 2 (a) is used, the multilayer thickness is generally increased as the chain length is increased, so that the relative interfacial structure is thickened, and the oil-in-water emulsifier is can play a role in preventing it from escaping, and as shown in FIG. 2(c), even when an organic alkali agent having a bulky structure with branches is used compared to FIG. 2(a), the interfacial structure is thickened and strengthened, and the oil-in-water type It serves to prevent the emulsifier from escaping to the outside, thereby preventing the wax and oil components from melting, thereby improving adhesion.

The mascara composition may be for eyebrows or eyelashes, but is not limited thereto.

The mascara composition may have improved spreading and spreadability.

In a specific embodiment, the composition of the present invention includes an oil-in-water emulsifier in a multi-layered structure, including an alkyl phosphate neutralized with an alkali agent, to prevent the emulsifier from being desorbed in sweat, tears, and oil, thereby improving smearing and spreadability. confirmed that.
