Environment, Safety, Health

Product Safety: Gaylord Chemical Company LLC produces chemicals that are often safer alternatives to other chemicals. Dimethyl Sulfoxide is recognized by the International Conference on Harmonization(ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use as a solvent with low toxic potential, Class 3. As such, DMSO is widely used in the pharmaceutical industry.

Another Gaylord Chemical Company LLC product, Dimethyl Sulfide (DMS) has much lower toxicity than other sulfiding agents in oil refineries. DMSO is also odorless in the same use.

The Superfund Amendment and Reauthorization Amendment (SARA) of 1986, often called “Community Right to Know”, has several requirements for industrial facilities to report information about toxic chemicals handled at their facility to the public; this is done through various means and some state and local requirements may be more stringent than the Federal requirements. One important Federal requirement is known as the Toxic Release Inventory (TRI) Report where facilities annually report emissions of certain particularly toxic chemicals.

NONE of the chemicals produced by Gaylord Chemical Company LLC require reporting as a “TRI” compound. It is often an advantage to substitute DMS or DMSO in place of TRI chemicals to make a safer workplace and community.

Product Information: Gaylord Chemical Company LLC provides extensive product information to assist customers in safely handling and using our chemicals. This includes product information bulletins and Safety Data Sheets (SDS). In addition, Gaylord Chemical Company LLC, along with other producers, is participating in the High Production Volume (HPV) Challenge Program. We are cooperating with the EPA to voluntarily gather data needed to understand and characterize the potential hazards of chemicals produced in the largest quantities.

This information includes physical-chemical properties data, information on the environmental fate of our products, and eco-toxicological and toxicological data. The data is being provided to the public after review by EPA and other interested parties. Gaylord and other cooperating producers have sponsored expensive testing to provide data needed to fill the gaps in the information.
