ASTM E640 – Preservation Test – Cosmetics

ASTM E640 is a standard preservation test method for testing performance of preservatives found in water-containing cosmetics.

ASTM E640 Commonly used for personal care and cosmetic products where the use of an effective and long-lasting preservative is a key consideration in formulation development, storage, and continual use.

ASTM E640 is a multi-cycle challenge test that exposes a product to a series of common microbes.

Typically tested to separate bacteria and fungal challenges, ASTM E640 can be modified to include specific organisms as found in actual production and use conditions.

Testing is commonly requested for product development, performance testing, and quality control testing.

It is important to test a personal care product’s preservation performance to meet customer expectations and to assure quality products batch after batch.
