Microbiological Analysis

The Microbiology Division offers a wide range of test and assays in line with the standards of ISO, Cosmetics Europe, PCPC (Personal Care Products Council) European Pharmacopoeia and FDA.

Specifically, the microbiology laboratory provides quantification, research, and identification services for specific microorganisms, as well as efficacy testing of preservative systems (Challenge test), antibacterial and antifungal activity testing, and mutagenesis testing.

Microbiological analysis offered by Abich:

  • Microbiological analysis on ingredients and finished products (cosmetics, medical devices and similar items): total viable bacteria count, yeasts and moulds count according to methods ISO (21149 e 16212), European Pharmacopoeia / USP, Cosmetics Europe, PCPC; Research of specific microorganisms according to ISO (21150, 22717,22718, 18416) European Pharmacopoeia /USP, Cosmetics Europe, PCPC.
