About this ingredient
Potassium Thiocyanate is a salt that forms part of some enzymatic preservation systems, specifically those based on lactoperoxidase. In a formula it helps generate compounds that slow microbial growth and keep the product stable. On applied skin it has no direct cosmetic action. This is a functional ingredient tied to preservation, not a treatment active. Its job is to protect the formula, not to work on the skin. Do not ask it for hydration or anti-aging effect; its value lies in keeping the product safe during use. With topical use, at the usual cosmetic levels, its systemic relevance is minimal, so you can use it during pregnancy and breastfeeding. Tolerance is good: irritation and allergy are both low, and it suits sensitive skin. At the amounts used in cosmetics it tends not to cause skin trouble.
