Our Departments

We take every possible measure to assist our clients, supporting their efforts during this critical phase. The product being tested will determine what department ultimately assists in your evolving needs. Based on the complexity of cosmetic safety testing, our clients often take advantage of numerous departments, such as:

  • Clinical — If testing a lotion, for instance, dermal irritation and sensitization testing will be an essential component of the pre-market testing and validation process.
  • In-Vitro Toxicology — Over the past 10 years, we have maintained focus on our in-vitro program for dermal and ocular irritation screening.
  • Microbiology — As expected, microbiology and formulation go hand-in-hand for cosmetic safety testing. From stability testing programs to sterility validation, we offer programs for all areas of cosmetic testing.
  • Photobiology — We are industry leaders in terms of our photobiology capabilities, offering SPF protecting efficacy, water resistant testing and more.
  • Analytical — Offering both development and testing support, CPT℠ has partnered with client firms to submit properly executed NDA, IND and ANDA documents.
