Polyaminopropyl Biguanide

Description

This is an effective preservative and antiseptic that is added to cosmetics to prevent the growth of bacteria, fungi, and yeast. It is often used in skin care products, eye care (even in contact lenses), or intimate areas, as it has a gentle action and does not irritate the skin when used in permissible concentrations. Additionally, it can have a soothing effect on irritated or acne-prone skin. In small doses, it is safe, but it is subject to restrictions in the EU due to potential risks at high concentrations.
