The Claim

Based on an oral LD50 greater than 2000 mg/kg body weight, EJUPAX is classified under the Globally Harmonized System as acute oral toxicity Category 5 with hazard statement H303 ("May be harmful if swallowed").

Verified by Lenz ·

The Short Version

The evidence does not support this classification as stated. GHS Category 5 oral toxicity is tied to H303, but it requires an LD50 greater than 2000 mg/kg and no more than 5000 mg/kg. Saying only “greater than 2000 mg/kg” is insufficient, because a substance above 5000 mg/kg would typically not fall in Category 5 at all.

Caveats

  • The claim omits the required upper bound of ≤5000 mg/kg for GHS acute oral toxicity Category 5.
  • A correct Category 5/H303 mapping does not prove EJUPAX belongs in that category unless its actual LD50 falls within the full 2000–5000 mg/kg band.
  • This wording can mislead users into treating “LD50 > 2000 mg/kg” as a complete GHS classification rule when it is only part of the criterion.
