About the Webinar

Mention 1,4 Dioxane and you're likely to get a variety of opinions and comments. But what are these based on - facts or fiction? Dr. Ricardo Diez gives us his perspective and tries to clarify the misconceptions around 1,4 Dioxane.

All ethoxylated emulsifiers have an internal ‘magic structure’ that makes them very efficient and versatile for formulating a wide range of cosmetic emulsions. Along with soap, they remain the most widely used emulsifiers on a global basis.

In the past few years, however, concerns about the presence of 1,4 Dioxane, a by-product of the ethoxylation process, has generated in some sectors of the industry an overzealous ‘need to replace’ them with non-ethoxylated materials. Oftentimes, these alternative materials are not as nearly as efficient or as versatile.

The fact remains that these ethoxylated emulsifiers contain very little 1,4 Dioxane. In fact, when used at typical concentrations found in cosmetic emulsions, the result is a finished product containing 1,4 Dioxane in the ppb range.

​​​​​​​Why do these materials have so little 1,4 Dioxane in comparison to ether sulfates? What is the ‘magic structure’ that makes these materials so unique and difficult to replace?  Why are they so important in the Lamellar Gel Network model for emulsions?  You'll find out in this presentation.

Dr. Ricardo Diez, Rutgers University (formerly of Chanel USA).

Many of you have had the pleasure of attending one of Dr. Diez'  IFSCC educational seminars as he travelled throughout Latin America on behalf of the IFSCC. Or perhaps you've attended one of his many Society of Cosmetic Chemists' continuing education classes. However you've had the chance to listen to Dr. Diez, you know how passionate he is about sharing his knowledge with others.

Ricardo Diez, Ph.D, is currently an Adjunct Professor at Rutgers University, (New Jersey, USA) where he teaches two courses on Applied Cosmetic Science in the Masters of Business and Science program.

He has more than four decades of experience in the industry in both consumer product companies (Procter & Gamble, Dial Corp and Chanel), and raw material producers (Miranol, Stepan and Huntsman). He has obtained patents in the fields of raw materials synthesis and consumer product technologies.

Mary Lynn Halland, Moderator

As Secretary General of the IFSCC since 2016, Mary Lynn supports all activities of the IFSCC. IFSCC Education Chair Perry Romanowski has Moderated all but one of the IFSCC's 33 webinars to date, with Mary Lynn working on the technology in the background. On this 34th webinar the roles will be reversed, with Mary Lynn attempting to Moderate, and Perry running the technology behind the scenes.
