TECHNICAL FIELD The present invention relates to a cosmetic comprising an impregnated member made of a PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer. More particularly, the impregnated member made of a PEIT copolymer has an amorphous fiber structure, A foamed urethane infiltrated member or a foamed NBR impregnated member having repeatedly formed polyester or polyether type impregnated with a cosmetic composition in a large amount and having a hardness value within a certain range, Gel or liquid type cosmetic composition is discharged in an appropriate amount and formed into a nonwoven fabric structure rather than being formed in a foamed form, so that the stretchability of the foamed urethane infiltrated member or the foamed NBR impregnated member of the conventional polyester or polyether type is improved And the impregnated member is pressed It is possible to use all of the cosmetic composition remaining on the lower portion of the impregnated member by being pressed sufficiently to the lower portion of the surface impregnated member and to form a polyester screen net on the impregnated member to adjust the discharge amount of the cosmetic composition discharged from the impregnated member, An impregnation member made of a PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer, which is impregnated with an impregnation member made of a PEIT copolymer and packed in a compact type container to improve the portability and usability of a user, And to cosmetics containing the same. The impregnating member comprises a cosmetic composition, and the impregnating member is made of an ASKER hardener type F (Type A) hardener, Wherein the impregnating member comprises a polyethylene glycol-isophthalate-terephthalate (PEIT) copolymer having a hardness in the range of 15 to 40, And the thickness of the fibers constituting the impregnating member is 20 to 60 占 퐉. The screen net is laminated on the upper end of the impregnating member, and the top of
