FORMULATION OF ANTI ACNE CREAM CONTAINING NATURAL ANTIMICROBIALS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2013, Vol 4, Issue 11
Abstract
This study investigates about the production of nano-emulsion from coconut oil, lauric acid, and liposome containing lauric acid, xanthone, and nano gold using advanced technology. In addition, the antimicrobial effect of produced nano emulsion and nano gold was investigated. Using ultrasound it was possible to produce nano emulsion from lauric acid with oil droplet size of about 100 nm within 30 minutes at 45C and 100 % amplitude. High pressure jet technique (at 3000 bars) was a suitable and fast method for production of nano emulsion using coconut oil. The droplet size of nano-emulsion was nearly independent of nozzle size (OD = 80 to 100 m) and ranged from 185 to 240 nm. Production of gold nano-particles using Turkevich’s method results in gold nano-particles of about 115 nm to 1385 nm dependent on concentration of gold solution. Atom Force Microscopy (AFM) confirmed the nano size of produced gold nano particles. In addition, the ultrasonic method was suitable to produce liposome from a mixture of lauric acid, xanthone and lecithin. The major parameter for droplet size of liposome was the concentration of lecithin in the sample. The optimum condition for liposome production using ultrasound was at 0.5 %, lecithin, 26 minutes and amplitude 90 % with average particle size of 116 nm. Xanthone concentration higher than 100 ppm was effective for the growth inhibition of Propionibacterium acnes (Propionibacterium acne). This showed that lauric acid has inhibition effect on Propionibacterium acne as well.
