Microbiology

At Kosmoscience, we bring together microbiological expertise, technology, and scientific methods to investigate the microbiological quality of formulations and their interaction with the skin microbiome.

Our studies include microbiological analyses, assessments of antimicrobial activity, and investigations into microbiota balance, generating evidence that supports the development of safe, effective products suited to the needs of the skin.

With technical rigor and a scientific approach, we turn insights from the microscopic world into solutions that strengthen product innovation, safety, and credibility in the market.

Scientific solutions for microbiological quality assessment, antimicrobial activity evaluation, and microbial community characterization

Microbiology | Safety and antimicrobial activity

  • Microbiological Control — Assessment of product microbiological quality under applicable regulatory requirements, including Brazilian RDC 907 and, for disposable personal hygiene products, RDC 640.
  • Challenge Test — Assessment of preservative-system efficacy under microbiological challenge.
  • Time-Kill Test — Assessment of antimicrobial activity over time.
  • Zone of Inhibition — Assessment of antimicrobial activity using an agar diffusion method.

Microbiome | Clinical studies and microbial characterization

Analyses are performed on biological samples collected from research participants.

  • Microbiome Profiling — Characterization of the composition and diversity of bacterial and fungal communities through sequencing.
  • Quantification of Specific Microorganisms — Detection and quantification of target microorganisms by quantitative PCR (qPCR).
