Description

Emulsion binder, cosmetic composition containing urethane powder, and preparation method thereof {EMULSION BINDER AND COSMETIC COMPOSITION CONTAINING UREATHANE POWDER, AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to an emulsion binder comprising a urethane powder, a cosmetic composition and a method for producing the same, and more particularly, in the preparation of a binder for bonding the powder component of the cosmetic composition, by forming into an emulsion formulation containing a urethane powder Emulsion binder and its manufacturing method, and the emulsion binder which can ensure the molding stability, the powdering phenomenon is reduced, the skin adhesion and persistence, but also have improved color development and use feeling, even if it contains a large amount of powder components It relates to a used cosmetic composition and a method for producing the same.

Cosmetic compositions, such as makeup, contain a powder component as a base component. Examples of such powder components include nylon, silica, and silicon-based powders. Recently, the trend of make-up products requires a strong pearl and bright color expression. Therefore, pearl is used a lot as a powder component in products, such as makeup. The cosmetic composition also includes a binder that binds the powder components for formulation.

As the binder, oils such as hydrocarbons, esters, triglycerides, and silicones are generally used, and about 5 to 10% by weight (based on the total weight of the composition) is used. As the binder, waxes or the like may be used in some cases.

Powder-like cosmetic composition, specifically, a cosmetic composition (such as makeup) including powder components such as pearl, nylon, and silica may be generally divided into a press formulation and a cream formulation.

However, the conventional powder-like cosmetic composition has the following problems depending on the formulation. In the case of press formulations, there are disadvantages such as dusting, color persistence, and molding stability. And, in the case of cream formulations, there is a merit of soft applicability, but there is a disadvantage that the skin adhesion is poor and oily feeling appears.

In addition, the conventional powder-like cosmetic composition is not able to maximize the content of the pearl which is being recently trended. For example, when maximizing the content of pearl in the press formulation, it is difficult to achieve the desired level of forming strength due to the repulsive force between the pearl particles and the large size of the pearl particles. In addition, even when using nylon, silica, silicon-based powder for the feeling of use as a powder component it is difficult to maximize the content due to the problem of formability as described above. For this reason, up to 50% by weight of powder components such as pearls have to be contained.

On the other hand, a method of using an excessive amount of oil or wax as a binder for the moldability may be considered, in this case there is a problem that a caking phenomenon occurs to greatly reduce the feeling of use of the cosmetic.

In addition, to overcome the above disadvantages, a method of mixing a thickener or a volatile solvent in addition to the oil as a binder has been attempted, but in this case it is difficult to formulate due to compatibility problems between the powder and the binder, for color development and feeling The problem of improvement still remains.

Therefore, the present invention is to solve the problems according to the prior art as described above, even if it contains a large amount of powder components to ensure the molding stability, reduced powdering phenomenon, improved skin adhesion and durability while high skin adhesion and persistence An object of the present invention is to provide an emulsion binder and a method for producing the same, and a cosmetic composition using the emulsion binder and a method for producing the same.
