Cosmetics

  • Examination of the microbiological purity of products and cosmetics raw materials, process water, packages
  • Performance assessment of preservatives
  • Total antioxidant capacity test
  • Extract obtaining in laboratory scale (method development)

  • Spray drying of water solution in laboratory scale (method development)
  • Development of cosmetics formulation
  • Comparison analysis of chosen cosmetics compounds
  • Species identification in cosmetics raw materials samples
  • Cyto- and genotoxity tests on cell lines, such as: primary skin fibroblasts and cells sampled from idividual person
