  RIPT

  Posted by Anonymous on March 2, 2016 at 6:19 pm

  I have a range of eye shadows (24) that are declined into various shades. The base formula is the same with only the percentage of colorants differing. My question is, for RIPT and In-Vitro EpiOcular testing can the group of eye colors be equally composited into one sample for testing? Or is it recommended to only test one eye shadow out of the group, perhaps the eye color with the most concentrated pigment? Or should each individual eye shadow be tested, which is rather expensive.

  Thank you for your help

  In the past, I have made a composite formula, using the maximum amount of every pigment in a group of shades, and used it for RIPT testing. This was for the US - I don’t know if it would be OK in the EU.
