APPARATUS AND METHOD TO DISPENSE HPC-BASED VISCOUS LIQUIDS INTO POROUS SUBSTRATES, E.G., CONTINUOUS WEB-BASED PROCESS
摘要:
Systems and methods are provided for dispensing compositions comprising sols, sol-forming compounds, or highly viscous compositions into porous substrates. In some embodiments, the porous substrates are elements of transdermal delivery devices. In some embodiments, the highly viscous compositions comprise alkylcellulose ethers, or derivatives thereof, in particular, hydroxypropyl cellulose. Such may be useful in continuous web-based manufacturing processes.
