본 발명은 콜린알포세레이트를 함유하는 필름코팅정 및 이의 제조방법에 관한 것이다. 더욱 상세하게는, 본 발명은 조해성을 갖는 콜린알포세레이트 정제를 성형한 후, 특정 필름형성제를 사용하여 필름코팅층을 형성시킨 필름코팅정; 및 이의 제조방법에 관한 것이다. 본 발명의 콜린알포세레이트를 함유하는 약학 제제는, 기존 연질캡슐제, 정제 및/또는 필름코팅정과 대비하여 별도의 제조공정이 없으며, 보관 안정성 및 복용 편의성이 뛰어난 효과가 있다.
摘要:
Provided herein is a water-based barrier coating composition suitable for use as a barrier coating, said composition comprising (A): (i) 40 to 95 % by weight of the total weight of (A) an aqueous polymer composition obtainable by free radical (co)polymerizing an ethylenically unsaturated monomer blend comprising (a) 0 to 70 % by weight of at least one optionally substituted styrene, (b) up to 100 % by weight of at least one C1-C4-alkyl (meth)acrylate, (c) 0 to 10% by weight of other ethylenically unsaturated copolymerizable monomers, in the presence of (d) 0 to 40% % by weight of degraded starch having a molecular weight M n of 500 to 10,000, wherein the sum (a)+(b)+(c)+(d) is 100%; (ii) 2 to 55 % by weight of the total weight of (A) of polyvinyl alcohol (PVA), optionally polymerized together with the components of (i); (iii) 2 to 30 % by weight of the total weight of (A) of a plasticizer; (iv) 5 to 30 % by weight of the total weight of (A) a composition comprising C16-C18 alkenyl ketene dimer, optionally as a mixture with rosin, whereby in the ratio of the C16-C18 alkenyl ketene dimer:rosin is from 100:0 to 25:75; (v) 5 to 20 % by weight of the total weight of (A) of a gelling agent; and (B): a filler.
摘要:
The present invention solves the problem of catalyst loss by encapsulating catalyst nanoparticles in an extremely thin, hydrophilic polymer film (thin film) rendering them more accessible to water and the incident light required for the photocatalytic reactions while retaining the photocatalytic nanoparticles in the thin film. Water dissolves into the film and diffuses to the catalyst surface where it is split into hydrogen and oxygen. Product gases then diffuse back out and are carried away by the water stream for collection and separation downstream.
