The Influence of Various Silicones on the Rheological Parameters of AZG Containing Silicone-Based Gels
Aluminium zirconium tetrachlorohydrex glycine (AZG) is a popular antiperspirant/deodorant agent, formulated in various forms including the clear gels. Silicones are used for the preparation of these gels, giving them desirable characteristics. The aim of this study was to investigate the influence of various silicones, when used in combination, on the rheological properties of the resulting AZG...

متن کاملEfficient synthesis of norbuprenorphines coupled with enkephalins and investigation of their permeability
An efficient approach for the synthesis of norbuprenorphin derivatives through coupling of enkephalins and norbuprenorphine intermediate is described. Norbuprenorphine derivative was synthesized from thebaine and then, its reaction with succinic acid and phthalic acid was also studied. Meanwhile, the synthesis of enkephalins was done using solid phase peptide synthesis approach. Furthermore, af...
