Potassium Sorbate

8.2

Ingredient Info

Potassium sorbate is a preservative used in skincare products to prevent the growth of mold, yeast, and some bacteria, helping extend shelf life. It's a salt derived from sorbic acid and is commonly used as a gentler alternative to stronger chemical preservatives.



Benefits

  • Prevents microbial contamination and mold growth
  • Generally considered milder than some other preservatives like benzalkonium chloride
  • Allows products to remain effective longer without refrigeration

Potential concerns

  • May cause irritation or allergic contact dermatitis in sensitive individuals
  • Not suitable for preservative-free formulations
  • Limited effectiveness against some bacteria compared to stronger preservatives

Science: Clinical research suggests potassium sorbate is less damaging to delicate tissues than benzalkonium chloride, making it a preferred alternative preservative in sensitive applications like eye products. However, peer-reviewed safety data specific to topical skincare use in the general population is limited.
