Description

Cosmetic composition {cosmetic composition}

The present invention relates to a cosmetic composition, and more particularly, to a cosmetic composition having improved stability and dispersibility by using any one or two or more cosolvents selected from isopropyl alcohol, polyol, and C6-C20 isoparaffin.

Recently, with the increase in women's social activities, the number of women who wear makeup is rapidly increasing, and accordingly, various demands for cosmetics are increasing.

In general, makeup cosmetics are composed of oily ingredients, powders, waxes, and water-based ingredients.

Powder, one of the ingredients constituting these makeup cosmetics, is an indispensable ingredient and is used to impart color and cover skin imperfections. Talc, mica, sericite, boron nitride, nylon, silica , extender pigments such as polymethyl methacrylate, titanium dioxide with excellent hiding power of skin imperfections, white pigments such as zinc oxide, vegetable powders such as ramicellulose or wood grain, iron oxides such as black iron oxide, and wire blue, Yellow No. 5 It can be classified into color pigments such as aluminum lake, chromium oxide, ultramarine, and legal tar pigments.

Depending on the type of powder contained in the makeup cosmetic, agglomeration due to re-agglomeration occurs, or the durability of the makeup is deteriorated due to poor adhesion, and the moldability of the powder is deteriorated.

In addition, various problems exist in the process of manufacturing makeup cosmetics.

The press process is a compression method using oil and wax as binders, and the binder content is generally limited. This has disadvantages in that, when an excessive amount of binder is contained, payoff and spreadability are reduced due to increase in hardness of the product, and the powder is not evenly dispersed. Products that use an excessive amount of pearl have a disadvantage in that the pearl effect is expressed low compared to the content of pearl used.

On the other hand, in the case of powder manufactured by a wet process, even if an excessive amount of binder is used, the powder can be evenly dispersed without caking. .

Korean Patent Application Laid-Open No. 2009-0126031 proposes a method of using a water-in-oil emulsion as a binder to simultaneously solve the hard texture and dusting of the existing press formulation, but there is still a need for research on a cosmetic composition suitable for various needs. .

Korean Patent Publication No. 2009-0126031

The present invention relates to a cosmetic composition, and more particularly, to a cosmetic composition comprising a powder mixture containing a powder component, isopropyl alcohol, and an auxiliary solvent.

The present invention provides a cosmetic composition, specifically, to provide a makeup cosmetic composition that improves dispersibility and stability while improving skin adhesion and glossiness.

The cosmetic composition of the present invention includes a powder mixture containing a powder component, isopropyl alcohol and an auxiliary solvent, wherein the auxiliary solvent is any one or two or more selected from polyol and C6-C20 isoparaffin.

1 is a photograph of the eye shadow (highlighter) cosmetic composition prepared in Example 1 of the present invention.
2 is a photograph of the eye shadow (highlighter) cosmetic composition prepared in Comparative Example 3 of the present invention.

The present invention provides a cosmetic composition that can be formulated in a variety of processes and has high skin adhesion, touch feeling and color development, and high molding stability at the same time.

The cosmetic composition of the present invention includes a powder mixture containing a powder component, isopropyl alcohol and an auxiliary solvent, wherein the auxiliary solvent is any one or two or more selected from polyol and C6-C20 isoparaffin.

The cosmetic composition of the present invention uses isopropyl alcohol as the main solvent and mixes any one or two or more auxiliary solvents selected from polyol and C6-C20 isoparaffin, resulting in low dispersibility and glossiness in the conventional press process. can overcome

Specifically, when an excessive amount of binder is contained in the general press process, payoff and spreadability are reduced due to increase in hardness of the product, and the content of the binder has been limited because there are disadvantages in that the powder is not evenly dispersed. Due to the limitation of the binder content, the pearl effect is lowered even when an excessive amount of pearl is used, and when an excess oil is used as a binder to secure moldability, stains or cracks occur on the surface of the molding.

Therefore, the wet process has been proposed as a process to compensate for the shortcomings of the press process, and in the case of products manufactured by the wet process, even if an excessive amount of binder is used, the powder is evenly dispersed without caking, the pearl feeling is increased, and a soft texture can be realized. However, formulation stability is low, and there are disadvantages in that cracking occurs during drying.

Therefore, the present invention uses isopropyl alcohol as the main solvent to overcome the disadvantages while maintaining the advantages of the wet process, and by using one or two or more solvents selected from polyol and C6-C20 isoparaffin together as an auxiliary solvent. We tried to overcome the same shortcomings.

By using isopropyl alcohol as the main solvent, it maintains the advantage of being easily evaporated without leaving any stains on the surface during formulation.

In addition, the present invention uses one or more solvents selected from polyol and C6-C20 isoparaffin as a co-solvent together with isopropyl alcohol, the main solvent, so that the stability and drying process of the formulation due to the high volatilization rate of the main solvent isopropyl alcohol. The cracking phenomenon was dramatically alleviated.

[Evaluation of skin adhesion, touch, appearance color and color development of manufactured makeup cosmetics]

In order to examine the skin adhesion, touch, external color and color development of the makeup cosmetics of Examples 1 to 3 and Comparative Examples 1 to 3, the same lotion was used on the same subject to match the skin condition as much as possible, and then prepared in the present invention. The makeup cosmetics of Examples 1 to 3 and Comparative Examples 1 to 3 were paid off three times with the same eye shadow tip, and the results of skin adhesion, appearance color, and color development were averaged by a 5-point measurement method, and the results are shown in Table 3 below. Five women in their 20s were applied and measured for each.

[Evaluation of molding stability and injection property of manufactured makeup cosmetics]

In order to examine the injection properties of the makeup cosmetics of Examples 1 to 3 and Comparative Examples 1 to 3, the shape coming out through the injection molding machine was observed. If the bonding strength is low, it is cracked and injection is made. If the binder content is too high or the compatibility is not suitable, the solvent is separated and injection is not possible.

In addition, for molding stability, the degree of cracking was confirmed by dropping the molding from a height of 30 cm.
