Antioxidants & Preservatives

Antioxidants and preservatives are often added to cosmetics to extend the shelf life of the product. These substances protect products against damage and degradation in order to keep their unique aroma, color or consistency, but some preservatives are suspected to trigger allergic contact dermatitis.

Precise quality control requires individual analytical standards! We offer neat standards and paraben multi-standard solutions in acetone for fast and easy multi-analyte detection.
