  Polysorbate 20 HPLC Testing

  Posted by Yulin on October 3, 2021 at 3:01 pm

  Anyone know of a lab that can HPLC test Polysorbate 20 for a reasonable cost?  I just need a test to verify if it is present or not.

  @Yulin If you just want to identify the presence of Polysorbate-20 (and it’s the sole material, and not a final product -cream, conditioner,etc.-), then you could use a FTIR, UV or any other spectroscopic technique you have available to identify it.

  @ketchito thank you!  I will have the lab try those methods.
