TOTAL MICROBIAL COUNT + Pathogen research (absence)
Cosmetic product shall be characterized by a limited presence of micro-organisms, therefore we perform research of bacteria, yeasts and molds and assess the absence of microbial growth after enrichment (absence of non-specific and specific (pathogenic) microorganisms).
TOTAL MICROBIAL COUNT + Pathogen research
The cosmetic product must be characterized by the limited presence of micro-organisms, to this end the research of bacteria, yeasts and molds is carried out and, in case contamination is found, the research (presence / absence) of the pathogenic microorganisms is carried out.
EVALUATION OF THE ANTIMICROBIAL POWER
Aim of the test is to evaluate the antimicrobial efficacy of a cosmetic product against specific microorganisms (S. aureus, P. aeruginosa, E.coli, C. albicans, A. brasiliensis, S. epidermidis, M. furfur ...).
EVALUATION OF THE ANTIBACTERIAL ACTION ON PLASTICS AND OTHER NON-POROUS MATERIALS
The test allows evaluating the antibacterial action on plastics and other non-porous materials, by using microorganisms (Escherichia coli, Staphylococcus aureus).
STERILITY TEST
The test allows checking the sterility of medical devices.
CHALLENGE TEST UNI EN ISO 11930
Challenge Test allows verifying over time the microbiological stability of the tested sample (storage and use). The test involves contamination of the sample with standardized strains of microorganisms (Bacteria, yeasts and molds) and the subsequent evaluation of the variation of microbial load by plate count (UFC / ml) of the number of live microorganisms at defined time intervals. The microbiological stability of the sample is then verified based on the observation of the microbial load reduction of the individual microorganisms within a certain time interval, according to specific acceptability criteria.
CHALLENGE TEST European Pharmacopoeia Ed 9.0
Challenge Test allows verifying over time the microbiological stability of the tested sample (storage and use). The test involves contamination of the sample with standardized strains of microorganisms (Bacteria, yeasts and molds) and the subsequent evaluation of the variation of microbial load by plate count (UFC / ml) of the number of live microorganisms at defined time intervals. The microbiological stability of the sample is then verified based on the observation of the microbial load reduction of the individual microorganisms within a certain time interval, according to specific acceptability criteria.
CHALLENGE USP (United States Pharmacopoeia) Chapter 51
Challenge Test allows verifying over time the microbiological stability of the tested sample (storage and use). The test involves the contamination of the sample with standardized strains of microorganisms (Bacteria: E.coli, P. aeruginosa, S. aureus, Yeasts and Molds: C. albicans, A. brasiliensis) and the subsequent evaluation of the variation of microbial load by means of the plate count (UFC / ml) of the number of live microorganisms at defined time intervals. The microbiological stability of the sample is then verified based on the observation of the microbial load reduction of the individual microorganisms within a certain time interval, according to specific acceptability criteria.
CHALLENGE TEST CTFA
Challenge Test enables the assessment of the microbiological stability of a tested sample over time (storage and use). This test concerns the contamination of the tested sample with standardized strains of microorganisms (bacteria, yeast and mould) and the subsequent measurement of the microbial load variation by plate count (UFC/ml) of the number of living microorganisms at defined time intervals. Based on the observation of each microorganism’s microbial load decrease within a certain time interval, the microbiological stability of the sample is verified according to specific acceptability criteria.
