Sodium Benzoate

Overview

Sodium Benzoate is widely used as a preservative in cosmetics and personal care products. It helps to prevent the growth of harmful bacteria and fungi.

Clinical Evidence

Sodium Benzoate has been identified as a potential allergen in various studies. For instance, a review highlighted its role in allergic contact dermatitis (ACD) associated with personal care products, emphasizing the need for careful labeling and allergen avoidance strategies (Allergic Contact Dermatitis to Personal Care Products).

Another study focused on the prevalence of fragrance and preservative allergens in cosmetic products, noting that Sodium Benzoate was among the most common preservatives found (Fragrance and Preservative Contact Allergens in Cosmetic and Household Cleaning Products in Turkey).

Additionally, research on toothpastes indicated that Sodium Benzoate is frequently used, with a notable percentage of products containing it (Mint condition? A survey of allergenic ingredients in UK toothpastes).

Conclusion

While Sodium Benzoate serves an important function in product preservation, its potential to cause allergic reactions necessitates awareness and caution among consumers and manufacturers.
