Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a make-up cosmetic composition comprising a shape memory polymer,

To a makeup cosmetic composition comprising a shape memory polymer.

Eye make-up includes shadow, liner, and mascara. Of these, eye shadow is the most versatile color that can be used to show the mood and personality of a person.

The eye shadow makeup composition can be broadly divided into powder type, cream type, liquid type and the like according to the formulation. Conventional powder eye shadows are the most commonly used eye shadow. It has good coloring power, it can make shade makeup by combining various colors, and has a merit that it can be used for a long time. However, there is a disadvantage that the adhesion is not good and the powder is broken and the durability is low.

Cream-type shadows are well-adhered to the skin and have less dusting, making it more natural to make eye makeup with a powdery finish compared to moist feelings. However, after a long period of time, a crease phenomenon appears and it has a disadvantage that it is easily erased in oil.

Liquid type eyeshadow is more convenient to use than powder type, and has advantages of less dusting and creasing phenomenon.

One aspect includes a shape memory polymer; Film forming agents; And a thickening agent.

The makeup cosmetic composition may be a liquid type. Generally, in the case of the powder type, there is a disadvantage that the adhesion is decreased, the powder is scattered, and the sustainability is poor. In the case of the cream type, the crease phenomenon appears after a long time, and the oil is easily erased. However, the makeup cosmetic composition of the liquid type according to one embodiment has the advantage of less dusting and crease phenomenon, and is not easily removed by sweat or oil. Among the above-mentioned liquid-type make-up cosmetic compositions, there is a product having excellent skin adhesion and frictional resistance including a shape memory polymer, but its stability at high temperature is inferior.

The makeup cosmetic composition according to one embodiment may be a composition which is stable even at high temperature stability, for example, at 25 ° C to 50 ° C. When the shape memory polymer is contained in a cosmetic composition, the shape memory polymer may be separated at a high temperature because the shape is recovered when the shape memorized at high temperature is deformed at room temperature and then heated again. However, the makeup cosmetic composition according to one embodiment has increased temperature stability in combination with the shape memory polymer, the film former, and the thickener.

The makeup cosmetic composition may be an eye shadow or a blusher.

The term "shape memory polymer " (SMP) means that, if a polymer is formed to have a uniform shape under certain conditions, even if the shape is changed by external impact thereafter, ≪ RTI ID = 0.0 > and / or < / RTI > The conditions may be, for example, temperature, light, pH, humidity, and the like.

The shape memory polymer may be a PEG-240 / HDI copolymer bis-decyltetradeceth-20 ether (PEG-240 / HDI copolymer). The PEG-240 / H-DIP copolymer bis-decyltetradeceth-20 ether was prepared by dissolving hexamethylene diisocyanate (PEG-240), decyltetradeceth-20 and hexamethylene diisocyanate monomer. < / RTI >
