Description

TECHNICAL FIELD [0001] The present invention relates to a composition for enhancing lash elasticity,

More particularly, the present invention relates to a composition for enhancing the elasticity of eyelashes, and more particularly, to a composition for enhancing the elasticity of eyelashes, The present invention relates to a composition for sustaining eyelash elasticity which is imparted with water resistance, cosmetic sustainability and elasticity, and which exhibits strong curling due to said elasticity.

Mascara is applied on eyelashes, curling eyelashes long, and is used to give a sense of volume to give beauty to the eyes. In addition, eyeliner is used to express the outline of the eye more clearly and to make the eyes more clear.

There are two ways to make the eye clearer: one is to separate the lashes one by one, as if the lashes are spreading, and the other way around is to convey the contents to one side of the lashes.

In addition, it is applied from the roots of the eyelashes and curled to lengthen the length of the eyelashes to make the eyes visually look bigger, and there is a method of expressing the eyes by refreshing the eyelashes by using long fibers.

As mentioned above, mascara has three characteristics of volume, curling and long lashes, and it is demanded as a basic requirement to have other tears and water resistance not to be exposed to sweat.

In general, the eye cosmetic composition can be broadly classified into an emulsion type, a film type, an emulsion film type, a planetary type, and an oily film type.

As the film type, a polymer emulsion prepared by emulsion polymerization of a natural latex or a water-soluble polymer as an emulsifier has been used as a film-forming agent. However, since such a film type formulation has poor water resistance of the polymer itself, sufficient water resistance among the requirements required for a mascara composition I can not meet.

The oily type is composed of a solid, semi-solid, liquid oil, and volatile hydrocarbon system, which has a disadvantage in that water resistance is good but oil resistance and drying property are very poor.

Early mascaras began as a form of application of a mixture of sodium stearate and carbon black in a solid form using a water-soaked brush, but over time, more convenient mascaras have been required, and a brush A type of mascara is being released. In addition, a soft type emulsion type mascara has been developed in order to improve the feeling of use of the conventional solid mascara.

The emulsion type mascara is a mixture of a vegetable ester wax or a hydrocarbon wax with a polymer to emulsify the emulsion type mascara. The polymer has an appropriate potency and high safety.

The above types of emulsification can be divided into O / W type and W / O type or W / S type having a great sustainability with respect to moisture. In order to increase the pear feeling, currently developed mascara can be separated from the emulsion type It is also used as a dispersion or oil dispersion type. These formulations are also used as decorating mascara, which gives the lashes glitter by using a top coat or a colorful pearl to enhance the persistence of the eyelashes against oil or moisture. Thus, mascaras are becoming increasingly subdivided according to their formulations and functions.

However, in the above emulsion type, the emulsion type of the underwater type mainly composed of solid, semi-solid, liquid oil, and water is liable to be erased in moisture, sweat, tears and the like, and the mascara The contents of the eyes are spread, and there is a drawback that the eyes are dirty when the time is continued.

Particularly, since most of the women in Korea have thin and lacerated eyelashes, when using the underwater wash-off mascara that is generally used, the lower part of the eye becomes black after a certain period of time, And the time for exposure to sweat or moisture is increased due to frequent external activities and leisure leisure time. Therefore, a technique for preventing mascara from spreading even in such various situations is recently required.

In accordance with this demand, mascara having a water-proof function using a resin or the like in an underwater-type mascara or a water-proof function in a water-in-oil type and an oil-dispersed type is being released.

Korean Patent Laid-Open Publication No. 2011-88179 discloses a water-in-oil type eye makeup cosmetic composition, which discloses a water-in-oil type cosmetic composition for water-in-oil type in which an aqueous phase containing an aqueous solution of an acrylate type copolymer as a film former is dispersed in an oil phase containing ester gum have.

Korean Patent Laid-Open Publication No. 2011-36297 discloses a long-lash mascara composition having excellent durability. In more detail, a high molecular weight polyethylene glycol-based polymer having a stretching effect and a polyacrylate- And a citric acid ester plasticizer is further contained therein. Thus, a composition having excellent long-term visual acuity and excellent durability without flaking phenomenon has been reported.

However, conventionally, a composition using a water-soluble acrylic polymer or a thickening agent and generally using a single-component powder is widely used for mascara and eyeliner, but it is still insufficient to realize sufficient water resistance, curling power, and makeup duration.

Accordingly, the present inventors have made efforts to achieve the physical properties required for conventional cosmetic compositions for eye make-up. As a result, the present inventors have found that conventional cosmetic compositions for eye make-up use water-soluble acrylic polymers or thickeners, Alternatively, the present invention provides a composition for continuously strengthening eyelash elasticity using a polyurethane component by simultaneously containing a silica-polyurethane-bonded powder or the silica-polyurethane-bonded powder and a polyurethane-water-dispersed film- The present inventors have accomplished the present invention by confirming that after the dispersion, the hair is not easily detached or hardened by external stimulation and is maintained for a long time and the elasticity of the eyelashes is increased to give strong curling.

More preferably, the composition for sustaining eyelash elasticity using the polyurethane of the present invention further comprises a film-forming agent in which the silica-polyurethane-bonded powder and the polyurethane are dispersed in water.

That is, the composition for sustaining eyelash elasticity using the polyurethane of the present invention is characterized in that the silica-polyurethane-bonded powder is dispersed in water, and then the film forming agent in which the polyurethane is water- will be.

Accordingly, the composition for continuous lash elasticity using the polyurethane of the present invention is a composition in which the conventional mascara composition is composed of a water-soluble acrylic polymer or a thickener and is generally composed of a single-component powder, while a silica- Characterized in that the silica-polyurethane-bonded powder and the polyurethane-containing water-dispersed film-forming agent are contained at the same time.

Thus, the preferable content of the silica-polyurethane-bonded powder as the main characteristic composition of the composition is 1 to 5 wt%, and the content of the polyurethane-water-dispersed film-forming agent is 10 to 30 wt%. As the composition components of the upper part and the oil part constituting the other composition, those which are used in a normal mascara composition can be applied.

Best Mode for Carrying Out the Invention Hereinafter, the present invention will be described on the basis of a composition to be performed in the embodiment of the present invention.

The eyelash elastic sustaining composition of the present invention comprises

(I) 1 to 5% by weight of silica-polyurethane bonded powder,

(Ii) 10 to 30% by weight of a polyurethane-water-dispersed film forming agent,

(Iii) 0.5 to 50% by weight of an emulsifier;

(Iv) from 2 to 40% by weight of pigment and

(V) 1 to 60% by weight of a wax base.

The present invention includes an aqueous phase dispersed in a liquid fatty phase containing at least one volatile organic solvent, and the aqueous phase contains a powder in the form of dispersed solid particles and covered with a coating liquid .

More specifically, the lash elasticity sustaining composition of the present invention comprises (i) a silica-polyurethane bonded powder.

In the above, (i) the silica-polyurethane bonded powder is a structure in which polyurethane surrounds silica by physical bonding, not chemical bonding, and flexibility between the two powders is maintained so that each powder function is exerted, The oil absorbing power is excellent and the elasticity is excellent, so that the composition is coated on the eyelashes and is resistant to sebum and provides the advantage that the function can be maintained for a long time.

In addition, (i) the silica-polyurethane bonded powder has a flexible combination of the functions of the two powders, so that it is not easily fallen or hardened by external stimuli after dispersing, and the elasticity of the eyelashes is enhanced to have strong curling.

On the other hand, in the case of the conventional cosmetic composition for eye make-up, since the powder is dispersed and dispersed without flexibility among the powders, it easily falls or hardens due to external stimuli.

The (i) silica-polyurethane bonded powder may be prepared at a blending ratio of 95 wt% of silica and 5 wt% of urethane, or a commercial product may be used, and a preferable content of the silica-polyurethane is 1 to 10 wt% In the embodiment of the present invention, 5 wt% is used, but the present invention is not limited thereto.

(Ii) 10 to 30% by weight of a polyurethane-water-dispersed film-forming agent, wherein when (i) the powder is incorporated simultaneously with the silica-polyurethane bonded powder, the mascara Is applied to eyebrows, the problem that the elastic silica alone is easily separated by external stimulation is solved. That is, unlike conventional film formers, polyurethane water-dispersed film formers are more flexible in film formation, are not easily cured to external stimuli, and have high elasticity, so that curling force can be sustained for a long time.

It can be used on mascara as well as on eyeliner, and on skin surfaces that require more flexibility on the surface, providing greater durability and flexibility than ever before.

The (ii) polyurethane-water-dispersed film forming agent may be formulated so that 30 to 50% by weight of polyurethane is dispersed in water, or a commercial product may be purchased and used. At this time, if the content of the polyurethane-water-dispersed film-forming agent is less than 10% by weight, the film forming function is weak and the use of more than 30% by weight can be used. However, the time point at which the mascara hardens It is impossible to obtain a resilience effect.

The lash elasticity sustaining composition of the present invention is characterized in that (i) silica-polyurethane bonded powder or (ii) silica-polyurethane bonded powder and (ii) polyurethane- , It has excellent water resistance, cosmetic sustaining ability and curling effect compared with conventional cosmetic compositions for eye make-up.

(Iii) The emulsifier may be selected from the group consisting of Polysorbate 80, Glyceryl Stearate and Acacia Senegal, alone or in combination thereof in the eyelash elastic sustaining composition of the present invention .

At this time, the preferable content of the emulsifier is 0.5 to 50% by weight of the total composition.

In addition, the composition for sustaining an elastic lash elasticity of the present invention contains (iv) 2 to 40% by weight of a pigment.

The term " pigment " in this specification means a powdery coloring agent used in a conventional cosmetic composition. The types of pigments used in conventional cosmetic compositions can vary widely, but are preferably selected from talc, mica, sericite, boron nitride, nylon, silica, polymethylmethacrylate, titanium mica, bentonite, Titanium oxide, iron oxide, ultramarine, carbon black, zinc oxide, chromium oxide, chromium hydroxide, alumina, calcium silicate, calcium carbonate, and combinations thereof.

And more preferably selected from the group comprising sericite, boron nitride, nylon, silica, iron oxide, carbon black and alumina, and combinations thereof, and most preferably iron oxide and carbon black, , And pigments used in the art can be used without any particular limitation.

In an embodiment of the present invention, the iron oxide and the carbon black are each contained in an amount of 1 to 20% by weight based on the total weight of the composition, thereby improving the sustainability and function of the composition for sustaining eyelash elasticity.

At this time, if the content of the pigment is less than 2% by weight, the color of the mascara hardly maintains black color. If the content of the pigment exceeds 40% by weight, it is difficult to exhibit the effects such as elasticity and water resistance required for mascara.

In addition, the composition for sustaining an elastic lash elasticity of the present invention comprises (v) 1 to 60% by weight of a wax base.

The wax used in the present invention may be selected from plant waxes including Carnauba wax and Candelilla wax, animal waxes including beeswax, lanolin, ozokerite Mineral waxes including Ozokerite Wax, Ceresin Wax and Polyethylene Wax, and petroleum waxes including Paraffin Wax and Multi Wax.
