About Us

Our History
Our History

During the 1940’s, Zein was processed into yarn and used in the manufacture of stockings. This very high volume application ended with the discovery of nylon and rayon.  Eastman Kodak, which had used Zein as a coating in the manufacture of photographic film and paper, began to use synthetic, petroleum-based coatings instead. Zein producers, primarily corn milling companies, began to leave the market.  

Brothers Joel Freeman and Paul Freedman, both chemists and owners of Freeman Industries, understood the unique coating properties of Zein and started to purchase it from one of the remaining smaller producers. Working closely with customers, they identified multiple applications for Zein in the food, confectionery, and pharmaceutical industries.  They developed different formulations using Zein, which met specific specific customer requirements better than just using Zein alone.

When the last of the corn millers stopped producing Zein, Freeman hired a Zein and extraction expert, purchased land and a building in Ashburnham, MA, acquired the needed equipment and set up Flo Chemical Corporation as a manufacturing operation.  Flo has been producing Zein since 1976 and is the only North American manufacturer of Zein.

In 2012, Paul’s daughter, Rachel Freedman, joined the company to assist with marketing and sales. In 2014, Rachel became the principal owner and President of Flo Chemical Corporation, which now conducts business under the FloZein Products name, better reflecting the all-natural characteristics of our product line.  In 2018, Flo was recognized as a Woman-owned Business Enterprise (WBE).

Molecular Architect

Peter Mattei

Many otherwise useful ingredients cannot be easily administered to humans and animals.  For over a decade, Peter has focused on improving the biological uptake of these molecules while eliminating reliance upon synthetic ingredients for topical, internal and parenteral use.   


These novel chemical forms vastly increase bioavailability of active ingredients resulting in lower product usage and greater dosage control. This system also enhances the chemical stability of many compounds previously unsuitable for general consumer products.


As a molecular architect, Peter continues his research across a range of nano-scale media, driving new applications in food, pharma, lifestyle and personal care.
