Cleaning Products with Purpose: Helping you navigate New York's S.4380 Regulation

Stay ahead of 1,4-Dioxane product requirements. Let’s talk about your alternatives today.

Univar Solutions works closely with strategic suppliers to get you what you need, when you need it.

Whether you’d like to improve existing products or identify new, enhanced formulations, our chemist and technical experts are ready to assist you in meeting your product performance goals.

Why is the regulation important?

Frequently found in cleaning products such as dish soaps and laundry detergents, 1,4-Dioxane is a by-product created during the manufacturing of ethoxylated chemicals. 1,4-Dioxane is a concern to human and environmental health due to its status as a known or suspected carcinogen by a number of authoritative bodies, including California’s Proposition 65 list, the National Toxicology Program, the U.S. Environmental Protection Agency, and New York’s S.4380 Regulation. As a result, the sale of household cleaning and personal care products containing 1,4-Dioxane will be extremely limited and regulated.

Though most personal care and cleaning products contain less than 5 ppm, this is higher than the New York S.4380 mandated requirement of 1ppm.With this new found health risk, manufacturers are rushing to take ensure their product meet the new standards ahead of the regulation deadlines.*


What does this mean for my products?

The new regulation puts in place a phase-down schedule that will see permissible levels set at ten parts per million (10ppm) for cosmetics, all the way down to 1ppm for certain personal care and cleaning products, by the end of 2023

Household cleaning deadlines:

  • 2 ppm, by December 31, 2022
  • 1 ppm, by December 31, 2023

Please refer to S.4389 for full details and compliance information.
