Katie’s Corner: SDS Authoring Tip – What are relevant ingredients?

Katie’s Corner is a new blog series we are introducing to our readers. Katie, a regulatory compliance associate and member of SiteHawk’s SDS authoring team, and one of only a handful of people in the U.S. to complete the AIHA Registry Program for SDS and label authoring is going to be providing tips and tricks for SDS authors and safety professionals. So please check back from time to time to get the latest news and best practices for authoring SDSs.

**What are relevant ingredients?** 

Q-Does relevant mean the ingredients that are active in our material?  A-Not necessarily

Q-Are they the ingredients that contribute to classification of your material? A- Yes,  IF they meet certain criteria

Q-How do you determine relevant ingredients?  A-They are ingredients that meet a specified percentage for the endpoint being considered.

*The concept of Relevant ingredients are only applicable to the following hazards: Acute toxicity, Skin Corrosion/Irritation, Eye Damage/Irritation and Aquatic toxicity.  EACH of these endpoints for each agency (OSHA and EU CLP) has its own statement of what is considered a relevant ingredient.  Coincidentally these are also the only hazards to which the additivity approach is applicable.  More on additivity approach later…

Regulatory citation: (an example of only the acute toxicity citation is provided below – for other endpoints please refer to the appropriate regulation)


Stay tuned, next time we’ll cover how relevant ingredients are essential to and apply to additivity.
