01The question
Is Benzyl Alcohol safe in serum?
CautionSerum
Naturally occurring (in some botanicals) and also synthetically produced preservative and solvent. Safe at cosmetic concentrations for most adults, but not for newborns.
02What the research flags
- Linked to gasping syndrome in neonates at high IV doses (benzyl alcohol-preserved saline)
- Skin sensitizer in some individuals
- Contact allergy more common in people with pre-existing eczema
- EU fragrance allergen — must be disclosed above 0.001% in leave-on products
