Potassium sorbate is a common ingredient found in skincare products, particularly in those that aim to preserve the formulation and extend its shelf life. It is a potassium salt of sorbic acid, which is a naturally occurring organic compound. Potassium sorbate is widely used as a food preservative, and its application in skincare products serves a similar purpose.
Preservatives play a crucial role in preventing the growth of microorganisms, such as bacteria, fungi, and yeast, in cosmetic formulations. Skincare products, especially those that contain water or water-based ingredients, are susceptible to microbial contamination. This can lead to product spoilage, unpleasant odors, and even potential health risks for users.
