Phenoxyethanol
Phenoxyethanol is a widely used synthetic preservative with global approval for use in rinse-off or leave-on cosmetic products in concentrations up to 1%. It’s often used in even lower amounts, especially when combined with other preservatives.
Phenoxyethanol is incredibly versatile in that it works in a large range of formulas and pH ranges and offers broad-spectrum activity against many pathogens. It is both water and oil soluble and is compatible with many other preservatives used in cosmetics.
