Important changes to EN 13697

The latest update, EN 13697:2015+A1:2019, has now been published. Amongst the changes are some important ones, which may require you to have further testing done on your products.

  1. The interfering substance for testing against Pseudomonas aeruginosa, under clean conditions, has now been reverted to 0.3 g/l bovine albumin.
    In line with ECHA guidance, prior to this revision, we had already made this change and included a note in test reports as justification. However,
  2. The 2019 amendment has also changed the way in which both Pseudomonas aeruginosa and Candida albicans test suspensions are prepared. Both must now be prepared 10x stronger than in previous versions.

Tests done to EN 13697:2015 are still valid, with the exception of any tests done against Pseudomonas aeruginosa or Candida albicans under clean conditions.
This applies if even if the clean conditions (for Pseudomonas aeruginosa) had been amended to 0.3 g/l bovine albumin, in accordance with ECHA guidance.

If you believe you are affected by these changes, please contact us for more details.


Is Beeswax Antimicrobial?

Over recent years beeswax has gained popularity within the cosmetics industry. It is commonly found in lip balms, moisturisers, shaving creams  and other cosmetic products. Beeswax is what bees construct honeycomb from and is composed of mainly hydrocarbons and long chain fatty acids, but is it antimicrobial?

It is often believed that beeswax is antimicrobial, however due to its composition, microbial susceptibility can vary between hives and seasons. There has been limited research into the antimicrobial properties of beeswax alone and many have been inconclusive due to differing extraction methods. However, there has been some evidence that beeswax has antibacterial properties when combined with other ingredients such as honey or alcohol.

An overview of some of this research can be read in the scientific paper below:
