Description

Cosmetic composition for make-up and stick-type providing refreshing feeling and pearliness and providing method thereof

The present invention relates to a stick type makeup composition that provides a refreshing feeling and a pearly feeling, and more particularly, to a stick type makeup composition containing a large amount of pearl pigment, dispersing the pigment in an aqueous phase rather than an oil phase and forming hardness. In order to use a hydrophilic coating agent such as gellan gum instead of waxes of high melting point, the present invention relates to a cosmetic composition that provides a feeling of cushioning and soft feeling like jelly with cool refreshing feeling in use.

In general, the stick-type cosmetics refers to lipstick in the cosmetic industry, which mainly aims to express the visual beauty of the lips, and also acts to protect the lips and maintain moisture (Korean Patent Publication No. 1990-4085). .

In addition to the lipstick, cosmetics manufactured in the form of sticks include foundation or eye shadow sticks, cosmetic removal or moisturizing sticks in skin care, and foaming sticks for skin cleaning. In addition, mention may be made of deodorant sticks used for the purpose of odor and deodorization (US Pat. No. 4,617,185) or aroma.

A common advantage of these stick cosmetics is that they are very convenient to use, so the potential product value is very high. However, in the case of sticks formulated on a wax base, they have a greasy property which is not preferred by users, and in addition to lack of freshness in application, it is difficult to incorporate an active hydrophilic material into the composition.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a makeup cosmetic composition of the stick properties containing the aqueous phase as high as possible.

Another object of the present invention is to provide a cosmetic composition that provides a refreshing cool feeling with a soft cushion feeling when used while containing the aqueous phase in a high concentration, and gives a bright pearl (pearl) through a large amount of included pigment.

In order to achieve the above object, the present invention is a makeup composition comprising 50 to 95% by weight of an aqueous composition comprising a hydrophilic coating agent and a moisturizing agent, and 5 to 50% by weight of a pigment comprising a extender pigment and a gloss pigment,

The hydrophilic coating agent is contained in an amount of 0.1 to 3% by weight based on the total composition, and the polysaccharide material by microbial fermentation wherein the hydrophilic coating agent comprises gellan gum or xanthan gum; Natural seaweed extracts including agar, carrageenan, or algin; Synthetic polymeric materials including polyesters, polyacrylates or polymethacrylates; And at least one selected from the group consisting of derivatives thereof,

The moisturizing agent is included in an amount of 1 to 30% by weight based on the total composition, the moisturizing agent is selected from one or more selected from the group consisting of 1,3-butylene glycol, glycerin, propylene glycol, dipropylene glycol, sorbitol and betaine ,

The aqueous phase composition provides a makeup cosmetic composition comprising a hydrophilic surfactant as a dispersant for the pigment at 0.1 to 5% by weight based on the total makeup composition.

In addition, the present invention is prepared by dispersing the coating agent while the coating agent is added to the moisturizer while heating, and then mixed with purified water and dispersant in a heated state to produce an aqueous phase composition, and after adding a pigment to the aqueous phase composition and heating the mixture And it provides a method for producing a stick-type makeup cosmetic composition having the above-described configuration comprising the step of quenching after pouring the mixture into a closed container at a high temperature of 70 to 90 ℃.

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

The present invention provides a stick makeup composition containing a large amount of pearl pigment, wherein the pigment is dispersed in an aqueous phase rather than an oil phase. In particular, the present invention by using a hydrophilic coating agent such as gellan gum (gellan gum) instead of waxes of high melting point to form hardness, gives a soft and cool refreshing feeling compared to the makeup cosmetics in the form of oil dispersion, hypoallergenic to the human body In addition to being safe, it provides a cosmetic composition excellent in dispersion stability and long-term storage stability.

The makeup cosmetic composition of the present invention comprises an aqueous phase composition and a pigment.

The amount of the aqueous phase composition in the makeup cosmetic composition of the present invention is preferably included in 50 to 95% by weight relative to the total weight of the cosmetic composition.

In the water-based composition, in order to impart a moisturizing feeling, 1.0 to 30% by weight of the moisturizing agent with respect to the total makeup cosmetic composition, 0.1 to 3% by weight with respect to the total makeup cosmetic composition, and a hydrophilic surfactant as a dispersant for the pigment as a whole make-up 0.1 to 5% by weight relative to the composition.

The moisturizing agent may be used by selecting one or more of 1,3-butylene glycol, glycerin, propylene glycol, dipropylene glycol, sorbitol and betaine. When preparing the makeup cosmetic composition in the present invention by selecting one of the moisturizing agent to be used as a pre-dispersing agent for the hydrophilic coating agent allows the coating agent to create an effective gelling phenomenon without agglomeration with each other. Here, the 'gelling phenomenon' means that the coating agent forms a strong macromolecular bond in the presence of a solvent to form a three-dimensional network capable of trapping all components including the aqueous phase therein. The humectant may be used in an amount of 1.0 to 30% by weight based on the total weight of the composition (relative to the total composition), and preferably 5 to 20% by weight. If the content of the moisturizing agent is less than 1% by weight, there is a problem in that the soft applicability is inferior in use, and when the content of the moisturizing agent exceeds 30% by weight, a sticky or unnatural coating feeling is felt.

Hydrophilic coatings include polysaccharide materials by microbial fermentation such as gellan gum and xanthan gum; Natural seaweed extracts such as agar, carrageenan and algin; Synthetic polymeric materials such as polyesters, polyacrylates or polymethacrylates; And one or more may be selected from the group consisting of derivatives thereof. Preferably, the hydrophilic coating agent is more advantageous to provide a unique feeling and refreshing feeling of the stick formulation to be achieved in the present invention when using a polysaccharide derivative material such as gellan gum or xanthan gum.

The content of the hydrophilic coating agent is 0.1 to 3% by weight based on the total composition. If the content is less than 0.1 part by weight, sufficient hardness is not formed and it is too soft to be used in the form of a stick. It is too hard to use and there is no refreshing or soft feeling when applied to the skin. It also hardens too easily during manufacturing or molding, making it difficult to work with.

As the dispersant for the pigment, for example, one or more of hydrophilic surfactants may be selected and used from triethanolamine (TEA) -stearate, polysorbate 20, polysorbate 60, and polysorbate 80. . The amount of the dispersant is 0.1 to 5% by weight based on the total composition, if the content is less than 0.1% by weight there is a problem that the dispersion is not uniformly dispersed, if the content exceeds 5% by weight, the feeling of application during the skin is less affected and hardness is also affected. There is a problem affecting.

In addition, the pigments used in the stick makeup composition according to the present invention include extender pigments and gloss pigments, and pearl pigments, also called pearlescent, as main pigment components. The mixing ratio of the extender pigment and the gloss pigment in the pigment component is preferably used by mixing in a ratio of 0.5 to 5% by weight: 1.0 to 30% by weight. The pearl pigment may be used by selecting one or more from mica titanium, iron oxide-treated mica titanium, bismuthoxychloride, young foil, natural pearl and the like. According to the present invention, in addition to the above-mentioned pearl pigments, as necessary, extender pigments such as talc, mica, kaolin, sericite, barium sulfate; Pigmented pigments such as iron sulfate, red iron oxide, black iron oxide, ultramarine, chromium oxide or mixtures thereof; White pigments such as titanium oxide and zinc oxide; And polymer powders such as nylon powder, polyethylene powder, polymethyl methacrylate powder, silicone rubber powder, silicone resin coated silicone rubber powder, and the like. Pigments may be used at 5 to 50% by weight relative to the total weight of the composition. At this time, when the content of the pigment used is less than 5% by weight can not expect the cosmetic effect as a makeup cosmetic, when the content of the pigment exceeds 50% by weight the pigment dispersing effect is reduced and the long-term storage stability of the emulsion is inferior .

In addition, the makeup cosmetic composition of the present invention may further include additives such as all kinds of ingredients usable in conventional cosmetics, such as sunscreen, perfume, preservatives, antioxidants, animal extracts, vegetable extracts and the like. At this time, the content of the additives is not particularly limited. In addition, the aqueous phase composition in the makeup cosmetic composition of the present invention contains a residual amount of water in addition to the above components.

In the method for producing a makeup cosmetic composition in the present invention, the coating agent is dispersed while the coating agent is added to the moisturizer and heated, and then purified water and dispersant are mixed therein to prepare an aqueous phase composition. Thereafter, a pigment is added to the composition including the aqueous phase component and then heated to prepare a mixture. The mixture is poured into a closed container at a high temperature and then quenched to prepare a makeup cosmetic composition having stick-like properties. When the mixture is poured into the hermetic container above, the temperature is preferably in the range of 70 to 90 ° C.
