Production of cosmetic purpose collagen containing antimicrobial emulsion with certain essential oils

In this study, reproducibility of the cosmetic purpose antimicrobial emulsion formulations containing collagen hydrolysate by taking the advantage of the antimicrobial features of the industrial essential oil plants including Thymus vulgaris, Origanum onites, Eucalyptus globulus and Mentha piperita was investigated. The formulations produced for this purpose were subjected to the microbiologic testings with respect to the disc diffusion method. As the result of the studies, the formulations containing O. onites and T. vulgaris were found to demonstrate the highest antimicrobial activity. In addition to this, the emulsions were subjected to the viscosity and particle size analysis and examined in organoleptic terms as well.

► Antimicrobial emulsion formulations with collagen hydrolyzate and essential oils were prepared for cosmetic purposes.
► The formulations produced were subjected to microbial testing based on the disk diffusion method.
► The emulsions were also subjected to testing the viscosity and particle size, as well as examined in organoleptic terms.
