ISO 22717:2015/Amd 1:2022

Overview

ISO 22717:2015/Amd 1:2022 is an important amendment to the international standard focusing on microbiological detection of Pseudomonas aeruginosa in cosmetics. Developed by ISO Technical Committee ISO/TC 217 in collaboration with the European Committee for Standardization (CEN/TC 392), this update refines testing procedures to enhance the safety and quality control of cosmetic products. The amendment introduces a Modified Eugon LT broth as an alternative growth medium to improve the enrichment and detection of Pseudomonas aeruginosa, a key pathogen of concern in the cosmetics industry.

This amendment ensures that cosmetic manufacturers and testing laboratories follow standardized, scientifically validated microbiological methods, aligning with international best practices. It supports regulatory compliance and helps safeguard consumer health by preventing contamination of cosmetic products.

Key Topics

• Detection of Pseudomonas aeruginosa
  Pseudomonas aeruginosa is a critical microorganism monitored in cosmetics due to its potential to cause infections and compromise product safety. This standard outlines reliable microbiological methods for its detection.

• Modified Eugon LT Broth Composition and Preparation
  The amendment specifies the composition of the Modified Eugon LT broth, detailing components such as pancreatic digest of casein, papaic digest of soybean meal, glucose, egg lecithin, polysorbate 80, and others. Preparation instructions ensure consistent broth quality:

  • Polysorbate 80 and egg lecithin are dissolved in boiling water first.
  • Other components are added with heating and mixed thoroughly.
  • Sterilized at 121 °C for 15 minutes and pH adjusted to 7.0 ± 0.2.

• Alternative Enrichment Media
  Modified Eugon LT broth serves as an alternative to the traditional Eugon LT 100 liquid broth, expanding options for microbiological laboratories to achieve robust enrichment of Pseudomonas aeruginosa during testing.

• Standardization and Compliance
  The amendment supports harmonized testing procedures globally, facilitating regulatory adherence and ensuring product safety consistency across markets.

Applications

• Cosmetics Manufacturing
  ISO 22717:2015/Amd 1:2022 applies to quality control laboratories within cosmetics production to test raw materials, in-process materials, and finished products for microbial contamination.

• Microbiological Testing Laboratories
  Accredited labs conduct routine microbial quality testing of cosmetics, employing the modified broth medium to reliably detect Pseudomonas aeruginosa.

• Regulatory and Safety Assessments
  Regulatory bodies and safety assessors use this standard as a benchmark to evaluate cosmetic product safety, preventing distribution of contaminated products.

• Research and Development
  Cosmetic R&D teams utilize the updated methods to ensure microbiological safety during formulation development and stability testing.
