Izvirni znanstveni članek
Oznake:
The solubility of chlorhexidine is highly dependent on the salt present in solution. The aim of present research was evaluation of the effect of two polymers: polyacrylic acid and methylcellulose on the pH of resulting preparation, containing chlorhexidine. Also the solubility aspect was considered ...

Oznake: thermosensitive polymers;photoprotection;UV radiation;N-isopropylacrylamide;
In this study thermosensitive polymeric microspheres obtained in former research were evaluated in vitro for their photoprotective activity. The UVA/UVB ratio was assessed at so called shelf temperature i.e. at 25°C, and at elevated temperature of 45°C. The evaluated polymers absorb higher levels of ...
