Compositions, kits and methods of preparing a biocompatible film for cosmetic or medical uses are disclosed. The compositions or kits contain polyvinyl acetal (PVA), siloxane and a solvent. The siloxane can have a hydrophilic group. Once the solvent content is reduced, for instance, by evaporation, the mixture of PVA and siloxane is solidified, forming a film. The compositions and kits, optionally, further include one or more of an antimicrobial agent, a pigment, an anti-inflammatory agent, an anesthetic agent or a hemostatic agent. Such a film can be used, for example, in the form of an antimicrobial sealant, a liquid bandage, body paints, scar camouflage, water-proof sun block, makeup sealer, or antimicrobial wipe or spray.
揭示了用于化妆品或医疗用途制备
生物相容性薄膜的组合物、套件和方法。这些组合物或套件包含聚
乙烯醇缩醛(PVA)、
硅氧烷和溶剂。
硅氧烷可以具有亲
水基团。一旦溶剂含量降低,例如通过蒸发,PVA和
硅氧烷的混合物会固化,形成薄膜。这些组合物和套件还可以选择性地包含一种或多种抗菌剂、
颜料、抗炎剂、
麻醉剂或止血剂。这样的薄膜可以用于制作抗菌密封剂、液体创口贴、身体彩绘、疤痕伪装、防
水防晒霜、妆前乳、或抗菌擦拭剂或喷雾剂等形式。
