Chemical Assays

Florida Skincare Testing provides a broad array of analytical services for product development and production quality assurance. Promptly confirming the content of OTC compounds in dermatological formulas facilitates efficient manufacturing processes and confirms long term efficacy. 

The list of active ingredients FST analyzes is long and diverse – from OTCs like Lidocaine and Salicylic Acid to most sunscreens. A simple inquiry can confirm that the instruments are prepared to evaluate any active ingredient of interest.


Microbiology 

Florida Skincare Testing offers microbiological services for pharmaceutical, OTC and cosmetic formulations, as well as the raw materials used to build these products. Microbial Enumeration Tests, under strict GMP protocol, are conducted by technical professionals and the results are provided to sponsors promptly.

In Vitro Sunscreen Testing 

FST performs a variety of analytical tests associated with sunscreen products. Substantiation of broad spectrum protection claims is the primary focus – the FDA "critical wavelength test", the COLIPA 2011, and the ISO 24443. Also, custom tests are often performed to evaluate photostability and estimate the SPF of a sunscreen formulation. 

Raw Materials Evaluations 

Raw Materials Evaluations

The raw materials are the foundation for quality formulation. FST analyzes in-bound raw materials to assure purity, potency and safety necessary for finished goods manufacturing. Importantly, trace impurities and microbiological elements are part of the evaluations. 

 


 

 

Fabric Testing / UPF Determination 

Fabric Testing / UPF Determination

Sun protective clothing is rated by a UPF system, analogous to SPF for sunscreen formulation. For example, a rating of 50+ UPF signifies that the fabric has been shown to protect the skin from erythema 50 or more times than the ability of fair skinned people’s natural protection. 

Florida Skincare Testing uses the accepted AATCC method, an in vitro process, to test submitted fabric. In addition, FST offers hangtags displaying the determined UPF which can be attached to the protective garment.
