Polyaminopropyl Biguanide

Polyaminopropyl biguanide is a water-soluble preserving agent. This ingredient is a broad spectrum bactericide that protects skincare products against gram-positive and gram-negative bacteria. It is a natural alternative to parabens – a trend that is gaining popularity.

Polyaminopropyl biguanide is often paired with phenoxyethanol or other preservatives that are effective against fungal growth, like yeast and mold, in order to create a fully effective preservation system.

This ingredient is also very gentle on skin, and it can be used in a wide range of water-based products, including lotions, creams, wipes and cleansers.
