Factors influencing the effect of carbomer - the effect of ionic strength in the release medium
Jan 17, 2019

When the ionic strength in the medium increases, the repulsive force of the negative charge in the carbomer molecule is offset by the increase in the concentration of the cation, and the formed colloid or emulsion structure is affected, and the thickening efficiency is lowered. In order to solve this problem, the presence of ions can be minimized; the concentration of y carbomer resin can be overcome to overcome the influence of electrolyte; the salt of encapsulated or encapsulated salt is selected to reduce the ionization of soluble impurities.
