The U.S. EPA has eliminated testing requirements for some high-volume (HPV) chemicals.
HPV chemicals refer to substances produced or used in the United States in quantities exceeding 1 million pounds annually, encompassing approximately 2,800 substances. The HPV Challenge Program, initially proposed by the EPA, is a voluntary initiative by companies. The product range includes personal care products, home cleaning products, home repair products, and automotive products. This program encourages companies to disclose information regarding the health and environmental impacts of HPV chemicals. Since the program's inception, U.S. companies have provided information on over 2,200 HPV chemicals. On March 16th, the U.S. Environmental Protection Agency (EPA) announced the elimination of certain testing requirements for six substances and all testing requirements for four other substances. This announcement is based on information from the first batch of testing rule announcements for certain high-production-volume (HPV) substances. The four substances whose testing requirements were eliminated are: Ø acetyl chloride (CAS No. 75–36–5); Ø imidodicarbonic diamide
