Hibiscus Posted January 23, 2007 Share Posted January 23, 2007 What lab does everyone use to have their products challenge tested?In B&B products how do you determine the shelf life based on the preservative. I have lotion that is a few months old and it hasn't grown anything that I can see, but I can't help but wonder just how long the shelf life is. Any suggestions on labs that do challenge testing would be nice.TIA Quote Link to comment Share on other sites More sharing options...
Bunny Posted January 23, 2007 Share Posted January 23, 2007 If you have a local college that has a microbiology department, give them a call. I do the poor man's challenge test. Get one tested right after use, then out of the same batch, use one for 6 months. Toss it in the car, toss it in the fridge, stick my fingers all in it. Let my kids use it..lol And get it tested again. Much easier on the pocketbook than a real challenge test. Just ask for an APC. There's a few labs you can send off to, but I can't find them in my bookmarks! Quote Link to comment Share on other sites More sharing options...

LOL!I like that it's local as well and i think a better chance it won't get lost in the mail or mixed up. I read about a kit somehwere not sure how affective it is:undecided Quote Link to comment Share on other sites More sharing options...
candlebean Posted January 23, 2007 Share Posted January 23, 2007 This may be a stupid question, but does the school charge you to test it or is it extra credit for some student? LOL - I assume they charge you, but I just wanted to double check..... Quote Link to comment Share on other sites More sharing options...

I read about a kit somehwere not sure how affective it is:undecided I used to do the at home test from Snowdrift farms first, that way I wouldn't be horribly embarrassed if my formula was totally off. If it passed the stick test, It then went to the school. The test from Snowdrift is NOT the be all end all, it doesn't give readings. You'll know if it's way off base or worth looking more into. I believe last time I did the test it was 25 bucks candlebean. Quote Link to comment Share on other sites More sharing options...
