General description

The thermal decomposition of zinc stearate was studied.

Application

Zinc stearate was used as a reference compound to study the infrared spectra of a colloidal stearate-capped ZnO catalyst substrate for analysing gas adsorption on a colloidal stearate-capped zinc oxide (ZnO) surface. It was also used to prepare the sample suspension injection required for improving the therapeutic treatment for periodontitis.

The purpose of this research is improvement of therapeutic treatment for periodontitis by using lipophilic and/or hydrophilic zinc materials. The sample suspension injections were prepared from zinc octanate (C8Zn), zinc stearate (C18Zn), zinc sulfate hepta-hydrate (ZnSO4) and tricalcium phosphate (ZnTCP)
