摘要： A composition is provided herein for preventing or retarding the formation of gas hydrates or for reducing the tendency of gas hydrates to agglomerate, during the transport of a fluid comprising water and a hydrocarbon, through a conduit. The composition is a homopolymer of vinyl caprolactam having the low molecular weight in the range of 500 to 2500, or copolymers thereof, in a defined solvent. Such homopolymers and copolymers preferably are made and applied in the defined solvent, which, most preferably, is a glycol ether such as 2-butoxyethanol.

摘要： A delivery system for delivering a tooth whitening substance to a surface of an oral cavity, comprising a film of flexible malleable polymer material having a tooth whitening substance as an integral component of said film, thus providing an active on said oral surface when said film is adhered to the oral surface, said film having a dissolution rate in the aqueous medium of the oral cavity such that the tooth whitening substance can release its active upon said oral surface to act effectively thereon within a predetermined period of time, said film being disintegrable thereafter after effecting its tooth whitening action.
