Potassium Sorbate + Sodium Benzoate
What is Potassium Sorbate + Sodium Benzoate?
Potassium sorbate and sodium benzoate are preservatives commonly used in foods and cosmetics to inhibit the growth of mold, yeast, and fungi. Potassium sorbate is a potassium salt of sorbic acid, while sodium benzoate is the sodium salt of benzoic acid.
These preservatives are popular in personal care products due to their effectiveness in extending shelf life and maintaining product integrity. The combined usage allows for lower concentrations of each, potentially reducing the risk of irritation, though sensitive individuals may experience skin reactions.
When seen on a label in cosmetic products, they ensure the product remains fresh and free from microbial contamination, which is particularly important for items like lotions and skincare products.
