Synthesis and Analysis of Selected Physicochemical Properties of Clay/Hydroxyapatite/Clitoria Ternatea Composites with Doped SiO2, TiO2, ZnO2 as an Additive to Cosmetics

Natural admixtures are sought that can enrich the composite with the components we desire and enhance some of its properties. According to the principles of “green chemistry”, they represent a great potential not only for material engineering, but can also be used as heavy metal adsorbents. Due to low toxicity of clay and hydroxyapatite, attempts were made to use the composite for the production of cosmetics and to establish closer cooperation with their producers. The composite was obtained by mechanochemical synthesis of yellow clay, hydroxyapatite, silica, TiO

with the addition of Clitoria Ternatea. Initially, the toxicity and carcinogenicity, the concentration of anthocyanins and chlorophyll was determined, the parameters of the porous surface structure of the samples were determined, and the effect of ionic strength and pH was examined. Theoretical calculations of the enthalpy of intermolecular complex formation were also made, thanks to which a potential model of the complex molecule was obtained.
