SCC Webinar: 1,4 Dioxane in Cleansing (or Rinse-Off) Products: A Survival Guide

Wednesday, November 11th, 2020 (1:00pm-2:00pm ET)

[Please Note: This webinar will be free for all SCC Members to attend. Members will receive an email on or around November 5th with a direct link to the registration page for the webinar. If you are a member and have not received an email, please contact us at]


Over the years, the cosmetics industry has failed to respond to misinformation spread by various organizations concerning the use of 1,4 Dioxane (1,4 D). This lack of a response, coupled with an ambiguous position from the FDA on the topic, has created the perception of a lack of safety in cleansers formulated with ether sulfates.

1,4 D is a potential carcinogen. The key issue and danger of its presence in cleansers has always been that it ends up in the water we drink. However, as a recent NCSU “Current Opinion Paper” indicates, industrial waste appears to be the key contributor to the presence of 1,4 D in drinking water. Despite this, new regulations such as NY State’s recent law limiting the presence of 1,4 D in rinse-off products to very low levels, are increasingly becoming a factor in the formulation of cosmetic products. But these restrictions need not limit our formulations adversely, and can instead serve as catalysts for creating cleansers using ether sulfates manufactured with reduced 1,4 D.

This webinar will review the unique chemistry of ether sulfates, which has made them such valuable, utilitarian, and difficult-to-replace materials. It will also include a discussion of rinse-off formulations that comply with the new NY State  limit of a 1 ppm 1,4 D max.


This webinar is intended for a broad audience. It will contain information relevant to various aspects of the cosmetics industry, including technical, processing, marketing and safety. It will also be of interest to those developing skin care products, given the similarities of the impact of 1,4 D regulations on that product category.

This webinar is available to all SCC members free of charge.
