Borate-polyol mixtures as a buffering system

摘要

A buffering system having a pKa which may be selected based on the environment in which the solution is designed to be used. Solutions containing the buffering system according to the present invention include borate-polyol complexes as the primary buffering agents, and may include one or more of the following: an aqueous liquid medium; an antimicrobial component; a surfactant component; a viscosity-inducing component; and/or a tonicity component. The borate-polyol buffering system may be formulated to have a lower pKa than traditional systems.
