ISO 22718:2015/Amd 1:2022

Overview

ISO 22718:2015/Amd 1:2022 is an important amendment to the international standard for cosmetics microbiology, specifically focused on the detection of Staphylococcus aureus in cosmetic products. Published by ISO and developed by Technical Committee ISO/TC 217 in collaboration with the European Committee for Standardization (CEN), this amendment updates the original 2015 second edition to include refined methodologies and alternative medium compositions.

Maintaining microbiological safety in cosmetics is critical to prevent contamination that can cause consumer health issues and product recalls. This amendment provides cosmetic manufacturers and testing laboratories with enhanced procedures for accurate detection and control of Staphylococcus aureus, a common pathogen that poses risks in cosmetic formulations.

Key Topics

• Detection Methods Update: The amendment introduces the option to use Modified Eugon LT broth as an alternative to the traditional Eugon LT 100 liquid broth for enrichment during microbiological analysis.

• Modified Eugon LT Broth Composition:

  • Pancreatic digest of casein 15 g
  • Papain digest of soybean meal 5 g
  • Sodium chloride 4 g
  • L-cystine 0.7 g
  • Sodium sulphite 0.2 g
  • Glucose 5.5 g
  • Egg lecithin 1 g
  • Polysorbate 80 15 g
  • Sodium lauryl ether sulfate 1.56 g
  • Water 1000 ml

• Preparation Guidelines: The amendment details the precise preparation process of the modified broth-including component dissolution order, sterilization at 121 °C for 15 minutes, and pH adjustment to 7.0 ± 0.2-ensuring optimal conditions for the selective growth of Staphylococcus aureus.

• Standardization and Compliance: The amendment aligns with ISO/IEC editorial rules and respects intellectual property aspects, aiming to promote harmonization in cosmetic microbiology testing internationally.

Practical Applications

• Cosmetic Microbiological Safety Testing: Laboratories testing cosmetic raw materials, intermediates, and finished products can adopt the modified Eugon LT broth to improve reliability and sensitivity of Staphylococcus aureus detection.

• Product Quality Control: Cosmetic manufacturers can implement updated detection protocols to identify and mitigate contamination risks early in production, reducing recall incidents and safeguarding consumer health.

• Regulatory Compliance: Adhering to ISO 22718:2015/Amd 1:2022 demonstrates commitment to globally recognized microbiological standards, facilitating market access and regulatory approvals in multiple regions.

• Research and Development: R&D teams formulating new cosmetic products can apply these methodologies to assess microbial stability and safety during product development phases.

Related Standards

• ISO 22718:2015 – The original second edition standard specifying microbiological detection techniques for Staphylococcus aureus in cosmetics.

• ISO/TC 217 – The ISO technical committee responsible for cosmetics standards, including microbiological safety and testing.

• ISO/IEC Directives, Part 1 and Part 2 – Provide the framework and editorial guidelines for the development and maintenance of ISO standards.

• European Committee for Standardization CEN/TC 392 – Collaborates with ISO on cosmetic standardization, ensuring coherence across European and international regulations.

• Other Cosmetics Microbiology Standards – Including ISO 17516 (microbiological limits for cosmetics) and ISO 21149 (detection of Candida albicans and other yeasts).
