Penreco® has been producing the highest quality products including USP/NF grade white oils and USP petrolatum’s for more than 120 years.

Over 20 of those years have been spent perfecting the manufacturing of our gelled hydrocarbon Versagel® product line. These three product lines can be and have all been used in cosmetic, personal care, and pharmaceutical applications. 

With a newly constructed multi-million-dollar manufacturing addition to our Karns City, PA plant we can now offer our customers even more highquality products. 

Not only do we have the manufacturing and processing experience, but we also have the technical experience and a technical team who is ready to answer any of your technical questions.
