It’s time for another chance for you to get your formulation questions answered.

This month we have forum member and microbiology expert Dr. Phil Geis! (@PhilGeis) He is an expert in the topic of cosmetic preservation.

There is a lot of misinformation on the Internet about preservatives, including effectiveness, safety, and what you should use when. This is your chance to get answers from a real expert with decades of experience.
He literally wrote the book on cosmetic preservation - Cosmetic Microbiology: A Practical Approach

So, register for this free webinar today.

@crillz - sorry! We have a worldwide audience so it’s hard to get a time that works for everyone. But be sure to sign up and catch the recording.

Completely understand and appreciate the learning possibilities Perry.
A question I wouldn’t mind asking is. If you are trying to make a moisturiser type product for commercial sale with a shelf life of 2 years are you better off leaving ingredients out such as soy lecithin, aloe vera and the likes or will a good preservative system make it not a worry.
I kind of think I may be answering my own question here but I wouldn’t mind the opinion of a pro.

Links for methods.
Many compendial methods folks use (e.g. ISO, PCPC, ASTM) require purchase. If the price is tough to meet - to understand how such testing can be performed, you might look at methods that have been published on line.

For preservative testing, see US Pharmacopeia 51
http://www.pharmacopeia.cn/v29240/usp29nf24s0_c51.html
or Europen Pharmacopoeia 5.1.3
https://www.drugfuture.com/Pharmacopoeia/EP7/DATA/50103E.PDF

For testing product quality (for microbes), see USP 61 (count) and 62 (specific microbes)
