Polymeric emulgel carrying Cinnamomum tamala extract: promising delivery system...
Arshad, Wajeeha; Khan, Haji Muhammad Shoaib; Akhtar, Naveed; Mohammad, Imran ShairCurrently, the use of natural compounds obtained from plants tremendously increased due to their promising therapeutic properties. The aim of this study was to formulate a stable emulgel formulation loaded with Cinnamomum tamala (CT) extract. The antioxidant activity of plant extract was determined by DPPH inhibition assay. The extract was successfully loaded into an emulgels using different concentrations of c...

Mahmood, Tariq; Akhtar, Naveed; Khan, Barkat Ali; Rasul, Akhtar; Khan, Haji M. ShoaibEmulsões múltiplas complexas possuem excelente habilidade de agregar grandes quantidades de agentes cosméticos funcionais. Este estudo teve por objetivo encapsular grandes volumes de chá verde em uma emulsão múltipla clássica e comparar sua estabilidade com a emulsão múltipla sem o extrato do chá verde. Emulsões múltiplas são desenvolvidas usando cetil dimeticona copoliol como emulsificante lipofílico e o cláss...
Development, characterization and antioxidant activity of polysorbate based O/W...
Khan, Barkat Ali; Akhtar, Naveed; Khan, Haroon; Braga, Valdir de AndradeThe objective of this study was to develop a pharmaceutical O/W emulsion containing plant-derived polyphenol extracts and evaluate its stability and antioxidant activity. O/W emulsions were prepared using ionic surfactant polysorbate 80 (Tween 80®). The odorwas adjusted with few drops of blue sea fragrance. DPPH (1,1-diphenyl-2-picrylhydrazyl) assay was used to evaluate the antioxidant activity of the plant ext...
