Sorbic Acid
What is Sorbic Acid?
Sorbic acid is an organic compound, specifically trans,trans-2,4-hexadienoic acid, found naturally in rowan berries and some other plants. In skincare and cosmetics, it primarily functions as a preservative by disrupting fungal and yeast cell membranes, preventing microbial growth that could spoil products. This action is most effective in acidic conditions, common in many formulations like lotions, creams, and serums. It also serves as a fragrance ingredient, imparting a mild, fruity scent or helping balance odors in the formula. Derived from natural sources but often synthetically produced for purity and consistency, it supports the stability of water-containing products without altering texture or appearance significantly. Regulatory bodies recognize its role in maintaining hygienic standards across personal care items.
