  4. 04It also acts as a mild penetration enhancer by helping active ingredients absorb slightly better.
  5. 05The common safety discussion around this ingredient involves a manufacturing byproduct called 1,4-dioxane.
  6. 06Trace amounts can form during production but the EU's Scientific Committee on Consumer Safety has concluded that levels at/below 10 ppm in finished products are safe (commercial products consistently fall within acceptable margins).
  7. 07True allergic reactions are uncommon and the CIR Expert Panel has confirmed this ingredient to be safe as used in cosmetics.
  8. 08Because it is derived from lauric acid, it may not be fungal acne safe.
