"None of the eight dispersants tested displayed
biologically significant endocrine disrupting activity."

Do you have link to the publication and data?

Was there insignificant "endocrine distrupting activity"?

Strange way to phrase this.

[justsaynomore]

I thought that was strange too - and why did they only focus on “endocrine”, what about neurotoxicity and other things?

[EBH]

It is standard EPA wording.

There is no legalese wording such as “insignificant,” but only various definitions throughout the regulations stating things to the effect of “Biologically Significant” meaning

because of the higher potential or more lasting consequences of harm

So the findings of the EPA study and their wording indicate that there is not a higher potential or lasting consequences.

Which as difficult as it might sound for some folks here ...matches the company’s MSDS.
