# Analysis of organic additives: Irgafos 168 (CAS No. 31570-04-4)

## You would like to carry out an analysis of organic additives: Irgafos 168 (CAS No. 31570-04-4)

### In what context should an analysis of Irgafos 168 be carried out?

The analysis of **Irgafos 168** (processing stabilizer) and the quantification of its degradation products (particularly the corresponding phosphate) are crucial. This approach allows for monitoring its consumption and assessing the polymer's condition.

**The objective of this analytical strategy is threefold**:

- **Ensuring durability: **
    - Ensuring the **long-term stability** of the finished product.
    - Preventing premature polymer deterioration (color loss, loss of properties).

- **Controlling quality and performance: **
    - Maintaining the effectiveness of other additives and active ingredients (e.g., UV filters in cosmetics, or primary stabilizers in plastics).
    - Preventing their own decomposition by ensuring sufficient protection.
- **Regulatory compliance:**
    - ****Rigorously controlling degradation product levels.
    - Ensuring compliance with safety standards and migration limits specific to each sector (e.g., cosmetics, medical devices).

The analysis of Irgafos 168 is the tool used to **certify the performance and integrity of the material** in the face of aging and external stresses.

### What is Irgafos 168 (CAS n° 31570-04-4)?

Irgafos 168 is a **phosphate antioxidant** widely used in polymers and organic additives to prevent thermal degradation. It protects materials from oxidation during processing, extends their lifespan, and stabilizes their final properties.
