摘要：
A package comprising a deformable material configured to form at least two sealed chambers, the package comprises: a first chamber； a second chamber； and optionally additional chambers, in which the chambers are separated by one or more fragile or tear barriers, in which the first chamber contains a low-speed liquid solution comprising an enzyme having perhydrolytic activity, in which the enzyme comprises SEQ ID NO: 1, and the second chamber comprises at least one acyl donor substrate, in which the acyl donor substrate is triacetin, and in which the second or additional optional chamber contains a source of peroxide and a gelling agent, of such that when one or more barriers between the chambers are broken after the first chamber is squeezed, the low-speed liquid solution is mixed with the peroxide source and the acyl donor substrate, the enzyme that has perhydrolytic activity catalyzes a reaction between the peroxide released by the peroxide source and the acyl donor substrate to form a peracid, in which after mixing and formation of the peracid, is formed to a gel extrudable by the liquid and the gelling agent, comprising the peracid, whose extrudable gel is suitable for extrusion and application to a dental surface, for sufficient time to whiten the teeth, in which the gelling agent, peroxide and ester compound of carboxylic acid are all in powder form, and in which the package has an opening means, optionally a marked region, cap or plug to allow the opening of the package, to provide an outlet through which the mixture can be supplied .Un paquete que comprende un material deformable configurado para formar por lo menos dos cámaras selladas, el paquete comprende: una primera cámara； una segunda cámara； y opcionalmente cámaras adicionales, en el que las cámaras se separan por una o más barreras frágiles o desgarrables, en el que la primera cámara contiene una solución líquida de baja velocidad que comprende una enzima que tiene actividad perhidrolítica, en la que
