  • Sodium Benzoate + Vitamin C Compatibility

    Posted by Alexis on January 18, 2024 at 3:38 pm

    Hi all,

    Very new to cosmetic science, but wanting to add a simple serum/toner mist to my line in form of a technology known as cellular extract.

    I have done some research which suggests that Vitamin C - L-ascorbic acid in the presence of Sodium Benzoate can react and form benzene which is a known carcinogenic and DNA disruptor.

    The company I wish to purchase the extracts off use sodium benzoate as their preservative, and the extract I wish to purchase is a plant profile containing up to 2300-3100 mg/100g of natural vitamin C in a water soluble format. The plant extract is a technology which basically encapsulates the plant profile at a cellular level into an aqueous solution + its full entourage of phytocompounds, micronutrients and enzymes.

    As the vitamin C is not synthetic, but biological ascorbic acid, would this concept of the vitamin C reacting with the sodium benzoate still apply?

    From my understanding synthetic ascorbic acid has the exact same molecular structure as biological vitamin C.

    I would appreciate someone with experience chiming in and shedding some light on this topic.

    Thanks so much
