Checking a foundations ingredients. Are either of these guia blockers? ISOEICOSANE and C9-15 FLUOROALCOHOL PHOSPHATES When an ingredient is not on either the Salicylate FREE or Salicylate to AVOID list how can I find out if it is a guia blocker? If the above two ingredients are okay you can add L'Oreal Paris True Match Super-blendable makeup (foundation) to the safe to use product list. Thank you for your help, J.
