Cosmetic Microbiology Services
No of Samples
Testing your cosmetics in this way is one step in assuring you that you have a safe product to sell and knowing that it is not adulterated. Please send 1-2 ounces of your product, preferably in the same container that you sell it in. Do not send it in a plastic zip lock bag. Be sure your product is labeled with your name/company name and a product identification name.
Send product along with the contact sheet you download below and a check for $31 (or other appropriate amount) or send Paypal.
The procedure will follow the guidelines of the US Food & Drug Administration (FDA) for microbiological methods for cosmetics. Testing takes 10 days to 2 weeks.
The FDA does not require any microbiology testing but it is a responsible thing to do to protect your formula and your customer. The FDA does say that a cosmetic should not be adulterated which is interpreted as meaning it should not contain harmful bacteria or fungus.
Stability testing is separate and tests whether your emulsion will stay together. Stability is ‘accelerated’ with increased heat to simulate time.

Although it is ideal to test every batch, this is impossible for many small crafters. My suggestion is to have initial testing done to make sure your product is well preserved and then do periodic testing (random) to make sure your GMP is good.
Additional services are available on a consultation basis. These might include gram stain, challenge testing, Mean Inhibitory Concentration (MIC). Pricing for these will vary depending upon details.
