The FDA does not expect cosmetic products to be absolutely sterile, but they must be free from pathogens. If the total counts are non-detect, then you have reasonable assurance your products are acceptable.
Positive results must be investigated at commercial microbiology lab to ensure the absence of pathogens before products should be sold. If Chek-It tm results are non-detect, a good preservation system will prevent growth of any organisms introduced during use.
Each Chek-It Kit tm comes with 10 slides, 10 double-tipped sterile swabs, instructions and result interpretation guide.
