Good day everyone. I am new to the cosmetic industry and is required to acquire a Certificate of Analysis or Good Manufacturing Practices certificate to enable my product to be sold on several forums. Can someone provide in detail information on what specific testing is most recommended to obtain the latter mentioned. In addition, should I conduct testing that may be required in the future? I have contacted several labs and they have quoted outrageous numbers. Is there anything I can do to personally ensure that the cost remain moderate? All advise is appreciated. What labs are best? Etc.
