Description

Volume mascara composition containing cationic polymer and powder coated with cationic polymer}

The present invention relates to a mascara composition containing a cationic polymer and a powder coated with a cationic polymer, and more particularly, a mascara composition containing at least one cationic polymer further contains a powder coated with a cationic polymer and thus has a volume And a mascara composition having improved sustainability.

In general, the purpose of using mascara is that women's desire to be beautiful is relatively short and poorly laid on the eyelashes, and small eyes are intended to express the eyes more vividly and vividly by wearing mascara and eyeliner makeup. In particular, since the eyelashes of oriental women are shorter and weaker than those of western women, there is a great desire to obtain a functional effect of volume and sustainability using mascara.

In mascara, the ideal volume means that the eyelashes are thicker than the original state, making the skin thin and rich, and the mascara liquid is applied to the eyelashes uniformly and tightly so that there is no powder bleeding or bleeding. Many methods have been developed to impart this volume, and the volume effect has been increased by using a large amount of a wax or film-forming polymer or powder.

However, when a large amount of spherical powder is used, powdering and deterioration of phenomena appear. When a large amount of polymer or wax is used, the volume is excellent, but the eyelashes are hard to maintain due to the weight applied to the eyelashes.

Looking at the conventional mascara composition patent or applied technology to solve such a problem, there is a patent application No. 2001-7002615 (L'Oreal) "mascara containing a film-forming polymer". The mascara may contain anionic polymers, cationic polymers and alkyl methacrylate nonionic film forming polymers to impart excellent persistence and curling power, but has a disadvantage in that the composition of this patent cannot impart excellent volumetric power.

In addition, the use of a cationic copolymer in the prior art is a patent application No. 2005-7013494 "eye care cosmetic composition comprising a low molecular weight cationic copolymer", the invention is a cationic copolymer and high The use of a mixture of molecular weight alcohols describes excellent durability against gloss and rub off.

Accordingly, the present inventors solved this problem in the mascara having a high volume of powder containing powder, when the volume of the eyelash is increased, the eyelashes may be generated and the eyelashes may appear as powder falling, eyelash, etc. over time. I studied how to do it. As a result, the coating of the surface of the powder with a cationic polymer increases the adhesion in the eyelashes, it has been found that the above problems can be solved and completed the present invention.

Accordingly, it is an object of the present invention to provide a mascara composition having excellent sustainability while improving application force by maximizing volume by using a cationic polymer and powder coated with a cationic polymer.

In order to achieve the above object, the present invention provides a mascara composition containing a cationic polymer and powder coated with a cationic polymer.

Since the mascara composition of the present invention has excellent adhesion to the eyelashes and has abundant volume and excellent persistence, it is necessary to meet the needs of various people, such as those who have thin eyelashes, those who prefer volulized mascara, and those who prefer excellent mascara. You will be satisfied.

The mascara composition of the present invention contains a cationic polymer and powder coated with the cationic polymer.

Hereinafter, the present invention will be described in more detail.

Since the eyelashes are charged with negative ions, using a mascara with a positive charge can increase the adhesion between the mascara and the eyelashes. Accordingly, the mascara composition of the present invention contains the cationic polymer and the powder coated with the cationic polymer, so that the mascara liquid can be applied to the eyelashes in close contact with each other, and no powdering or squinting occurs, and thus the durability is excellent. Can also be given.

Cationic polymer used in the present invention refers to any polymer comprising a cationic group and a group that can be ionized with a cationic group. The cationic polymer may be selected from those containing units comprising primary, secondary, tertiary and quaternary amine groups which may form part of the polymer backbone or may be side substituents bonded to the backbone. Specifically, copolymers of 1-vinyl-2-pyrrolidone and 1-vinyl-3 methylimidazolium salt which are quaternary vinylpyrrolidone and vinyl imidazole polymers (polyquaternium-16), dimethyl 1-di Aryl quaternary ammonium chloride homopolymers (polyquaternium-6) and copolymers of acrylamide and dimethyl diallylammonium chloride (polyquaternium-7). Commercially available products falling under this definition include BASF's trade names Luviquat FC 550, FC 370 and Ciba's trade names Salcare sc 10,11,30.

Other cationic polymers suitable for use in this patent include polysaccharide polymers including, for example, cationic cellulose derivatives and cationic starch derivatives. Cationic cellulose derivatives include salts of hydroxyethyl cellulose reacted with trimethyl ammonium substituted epoxide (polyquaternium-10) and polymeric quaternary ammonium salts of hydroxyethyl cellulose reacted with lauryl dimethyl ammonium substituted epoxide (Polyquaternium-24), commercially available products include Amerchol Corporation's Polymer JR series and Polymer LM-200. Other cationic guar rubber derivatives are also used, including, for example, guar hydroxypropyl trimonium chloride, a specific example being the Jaguar series from Rhone-Poulenc Incorporated. Cationic starch may be commercially available corn starch, potato starch (Farmal MS 5940, a corn product Korea). Cationic polymers may be used alone or in combination with other cationic polymers.

The amount of cationic polymer used in the composition of the present invention is 0.1 to 10% by weight based on the total weight of the composition, preferably 0.1 to 3% by weight relative to the total weight of the composition. If the amount is less than 0.1% by weight, it is difficult to expect the volume effect due to the small amount attached to the eyelashes, and when it is used more than 10% by weight, the viscosity of the water phase rises rapidly, so that the emulsification is not smooth when manufacturing mascara. Has its drawbacks.

The mascara composition of the present invention further contains a powder surface-coated with the cationic polymer in addition to the cationic polymer described above in order to provide a sense of volume and durability at the same time by resolving powder falling or under eyelid appearing with increasing volume.

Since the use of the same cationic polymer as the above cationic polymer is excellent in correlation, it is preferable to use the same.

The raw powder to be coated includes silica, nylon powder, cellulose powder, polymethyl methacrylate (PMMA) or a pigment, and specific examples of the pigment include iron oxide, chromium oxide green, chromium hydroxide green, ultramarine, titanium oxide, and mica. . The surface of the powder was coated with the above cationic polymer to adhere well to the eyelashes having anionic charge, thereby providing excellent volume and durability.

The coating material is contained in an amount of 1 to 30% by weight based on the total weight of the raw powder, and most preferably 5 to 20% by weight based on the total weight of the raw powder. This is too small when using less than 1% by weight can not expect the coating effect of the powder, when used in excess of 30% by weight the amount of cationic charge is increased, the agglomeration of the powder is generated and not easy to disperse This is because the emulsification is not made properly because it is difficult to formulate.

The powder coated with the cationic polymer used in the present invention contains 1 to 10% by weight based on the total weight of the composition. If the content is less than 1% by weight, it is difficult to expect the effect of increasing the durability due to the small amount of the powder itself. If the content is more than 10% by weight, application and adhesion are rather reduced, resulting in powder falling.

Hereinafter, the present invention will be described in detail with reference to Examples and Experimental Examples, but the present invention is not limited only to these examples.
