  • Chemical Analysis
  • Microbiology
  • Cyto-toxicity Testing
The ability of microorganisms to grow in cosmetics has been well established. Their presence cannot only bring about the deterioration of the product, but may also be deleterious to the user. This is also true if the chemical composition if not as labeled as it may prove the product to be ineffective or injurious to the user.

Northeast Laboratories with its staff of trained analytical Chemists and Microbiologists can provide the needed assurance that these products are not only safe for the user but contain the necessary ingredients for affective use.
