About Us


SLParkhurstCorporation  creates and deploys technologies that enhance daily life experiences.



SLP was co-founded in early 2000 by Stephen Parkhurst, Dr. Morey Osborn, Timothy Sullivan, Bill McLellan and Mark Smith to develop a more effective solution for odor management in bathrooms.  The result of this effort was the development of the NOVEXIUM® technology platform and the airNOVUS®  Biofilter device.  The company shifted its strategy and R&D focus in 2002 when it discovered that its technological innovations in using "Solution Phase Kinetics"  for odor elimination had broad capability and significant market potential beyond the bathroom environment. This shift resulted in the development of an array of NOVEXIUM® composites for use in consumer product applications such as disposable diapers, adult incontinence, feminine hygiene personal care, air spray deodorizers, fabric deodorizers, pet deodorizers, as well as product applications in commercial and industrial markets. 

SLP is now focused on  licensing  its patented and patent pending technology and providing bulk supply of  NOVEXIUM® products to a targeted group of large manufacturers for use in multi-billion dollar global product applications that span consumer, commercial and industrial markets.   SL Parkhurst Corporation is based in Austin, Texas.
