Cosmetics Testing Services

Princeton Analytical offers a full breadth of cosmetics testing services and will collaborate to design and implement a QC protocol to suit your needs.

The customer is your most important asset.  Failure is not an option.



We conduct quality control testing in parallel to your production process -- from raw materials and in-process samples through finished products.

Cosmetics do not need to be sterile; however, microbial contamination of cosmetics may: 1) impact product shelf life, consistency and performance, 2) result in failure to meet federal and state regulations, and 3) present risks to the consumer.

For make-up, lipsticks, nail lacquers, mascara, among others, Princeton Analytical provides aerobic plate count, identification of yeast and mold, and identification of pathogenic microorganisms, including: Staphylococcus aureus, Pseudomonas aeruginosa and E. coli.
