# Laboratory analysis of antioxidant additives

The **oxidation of cosmetic active ingredients** impacts the stability, efficacy, and compliance of formulas.

FILAB supports you with **antioxidant analysis** to characterize the **antioxidant capacity** of your cosmetic products and optimize their performance against oxidative stress.

## Are you looking for a laboratory offering its expertise to ensure antioxidant analysis in your formulas and finished products?

### Analysis of antioxidants: cosmetics, pharmaceuticals and plastics

Antioxidant analysis are used in cosmetics (formula stability, anti-free radical protection), pharmaceuticals (extending the shelf life of active ingredients), and plastics (preventing material degradation).

In the cosmetics sector, they play a role in preserving the integrity of active ingredients (oils, plant extracts, vitamins) and ensuring the durability of formulas against environmental stress.

### Antioxidant analysis on cosmetic formulations

Antioxidant analysis measures a cosmetic formula's ability to neutralize free radicals and resist oxidation, ensuring its stability and effectiveness. FILAB conducts these tests to validate your active ingredients and optimize the durability of your products.

- **Chemical tests**, such as DPPH, ABTS, FRAP, and ORAC, measure the reduction of free radicals or specific oxidizing agents under controlled conditions, often using colorimetric or fluorometric measurements.
- **Degradation assessment**, such as the prevention of color loss or rancidity in products exposed to oxidation.

### Why carry out a laboratory antioxidant analysis on your cosmetic products?

Performing antioxidant analysis in cosmetics allows us to assess the effectiveness of antioxidant additives and ensure the stability of formulas against environmental stresses (UV, pollution, oxidation).

Free radicals, responsible for the degradation of active ingredients and oxidative skin aging, require precise measurement of antioxidant capacity in order to:

- Quality control of active antioxidant agent concentrations
  Analytical validation of antioxidant levels (vitamins, polyphenols, flavonoids, etc.) to ensure compliance with product specifications and guarantee the safety of cosmetic formulas.
- Assessment of the oxidative stability of cosmetic matrices
- Regulatory compliance assurance (EC No. 1223/2009) and claims validation
- Analytical support for the preparation of safety dossiers and efficacy claim dossiers (anti-aging, anti-pollution, natural), in compliance with European requirements.
- Formulation development support (R&D). Characterization of the antioxidant efficacy of new active ingredients or natural alternatives, optimization of dosages and ingredient synergies to formulate innovative and high-performance products.
