Benzoate comeback

Manufacturers of cosmetics and other products are seeing the benefits of using an old preservative, sodium benzoate, first used in the 1960s, instead of modern biocides, which have raised safety concerns recently. Consumers often shun products containing parabens, methylisothiazolinone, and imidazolidinyl urea because of alleged toxicity and skin sensitization problems perceived with these biocides. However, sodium benzoate has a proven track record as a safe and readily available preservative.
