βpreservative freeβ is not a flex. π«£
i was vetting a peptide serum for ivy & fields. loved the philosophy, loved the ingredients. but it had rose water, water soluble peptides, and no preservative on the list. so i asked the brand for the full ingredient list and they said they don't use preservatives or emulsifiers. π¬π¬
except that's not a flex. water is where bacteria and mold grow. a product with water and nothing to stop microbes can look fine, smell fine, and pass testing the day itβs made. months later, sitting on your bathroom counter, itβs a different product. itβs like putting takeout in the fridge and planning to eat it three months from now.
π clean beauty isnβt about avoiding preservatives. itβs about choosing safer, less controversial ones.
what could be happening is that the formulator may not know that the rose water they've purchased already contains a preservative. but that dose does *not* hold once you add the other 12 ingredients to the final product.
quick rules:
π§ water/aloe/hydrosol/floral water in the formula means it needs a preservative
π«§ water plus oil means it needs an emulsifier too
πΏ water-free products can usually be made without one, but they do benefit from added antioxidants
π§Ό saponification or high ph products can sometimes get away without a preservative (soaps)
iβm a proud member of the clean living community. i also care about basic formulation science and product safety. natural-looking doesnβt mean safe if the science isnβt there. π«Ά
