Sodium BenzoateCosmetics


Before listing sodium benzoate’s benefits, it must be noted that certain interactions with other chemicals may be harmful to a person’s overall health:

particular attention should be drawn towards the combination of sodium benzoate with ascorbic acid as one of the products that they yield is benzene, which is a known carcinogen, but according to the Food and Drug Administration’s (FDA’s) number of tests the vast majority of products that are sold in supermarkets, convenience stores or gas stations do not surpass the upper limit safety of containing 5 parts per billion (ppb) of benzene as determined by the World Health Organization (WHO)*;
another grey area is that of sodium benzoate’s link to hyperactivity when combined with artificial colouring as conducted by a 2007 Lancet study in the United Kingdom (results were inconclusive, however, as it was hypothesized that there was a greater likelihood in the hyperactivity behaviour being present due to the artificial colouring rather than sodium benzoate)

Moving along to the benefits that sodium benzoate provides:

counteracting autoimmune diseases by decreasing inflammation through inhibition, for example, of T cell proliferation or adhesion molecules;
decreasing cholesterol in the same way that statins do – through inhibition of the enzyme, HMG-CoA reductase;
effectively inhibiting the enzyme, D-amino acid oxidase (DAAO), which ultimately decreases activation of NMDA receptors that in turn contributes to an increased predisposition for certain cognitive disorders like Alzheimer’s or schizophrenia;
as a result of lower amounts of DAAO, one’s cognitive long-term potentiation or LTP is increased, which directly improves memory;
additional cognitive enhancements include increasing synaptic plasticity as achieved through increased activation of NMDA receptors and increasing certain growth factors present in the brain, such as Neurotrophin-3 and BDNF


Food and Beverage:

while most bacteria or fungi thrive under acidic conditions, that is not the case when sodium benzoate is among the ingredient list for either food or beverage, as the microorganisms are unable to continue growing in number;
in regards to human consumption, sodium benzoate’s most general application is used on acidic foods such as fruit juices, jams, condiments, pickles, salad dressings and carbonated drinks


as shown through a 2012 Orphanet Journal of Rare Diseases study, urea cycle disorders are alleviated through the use of sodium benzoate as it is able to lower ammonia levels as a result of binding to amino acids and making way for their excretion;
the signs and symptoms of schizophrenia, in conjunction with other therapies, benefit from a daily single-gram-dose of sodium benzoate as determined by a 2013 JAMA Psychiatry study;
the Journal of Neuroimmune Pharmacology provided a 2014 study showing the progression of encephalopathies such as Parkinson’s for mice subjects being inhibited as a result of sodium benzoate, which suggests the possibility of its future application being used for people suffering from the same diseases


with the modern omnipresent use of plastics, it has recently been shown that improved clarity and strength of polypropylene – used in packaging and labelling as well as textiles and laboratory equipment – is seen after the addition of sodium benzoate within its molecular structure


Sodium benzoate, a metabolite or derivative of cinnamon, is a food additive and preservative that is well-known for inhibiting the oxidation or decomposition of fats as well as disallowing the growth of certain micro-organisms, which include bacteria and fungi. There are minute amounts of sodium benzoate naturally found in apples, cranberries and prunes.


When the compounds, sodium hydroxide and benzoic acid, were neutralized the product that they yielded was the sodium salt, sodium benzoate. The polyunsaturated fat was first used for food preservation at the beginning of the 20th century and has since become a staple in that regard.
