About Methenamine
Methenamine is an organic amine.[1] In cosmetics, it is used to inhibit the growth of microorganisms in products and slow deterioration during storage.[4] In Europe, it is permitted as a preservative at up to 0.15%.[2] It is described as a colorless crystalline powder with no distinctive odor, so when it is in solid form, it is important to dissolve it first or disperse it evenly so that it does not clump in the formulation.[3]
