What is Antioxidant 1010? What are its uses?

I. What is Antioxidant 1010?

Antioxidant 1010, also known as pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid] ester (trade name such as Irganox 1010), is a multi-component hindered phenolic antioxidant formed by the esterification of pentaerythritol with four hindered phenolic units. It is one of the most widely used hindered phenolic antioxidants in the plastics industry. Its chemical formula is usually written as:

C73H108O12 (pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid], CAS No.: 6683-19-8, molecular weight approximately 1177.63)

It is a white crystalline powder at room temperature with a melting point of approximately 110-125℃. It is readily soluble in organic solvents such as chloroform, benzene, and acetone, but insoluble in water. Antioxidant 1010 contains four hindered phenolic (3,5-di-tert-butyl-4-hydroxyphenyl) active groups, which inhibit the thermal oxidative degradation of polymer materials during processing and use by capturing free radicals (ROO·, RO·, HO·, etc.) in the polymer oxidation chain reaction, thus breaking the oxidation chain reaction.

Structurally, antioxidant 1010 has a pentaerythritol core and four hindered phenolic arms symmetrically distributed. This high molecular weight multifunctional structure endows it with low volatility, extraction resistance, excellent thermal stability and good compatibility with most polymers. It can protect materials for a long time and prevent discoloration caused by light and heat. It is a representative product of "free radical scavenging" main antioxidant.

Chemically, antioxidant 1010 is stable, odorless, non-toxic, and does not contaminate products. When combined with phosphite-based auxiliary antioxidants (such as antioxidant 168), it can exert a synergistic effect, significantly improving long-term thermal stability. It should be stored in a sealed, moisture-proof, and light-protected environment.

This product is graded according to its application area, commonly including: industrial grade (for general industrial applications such as plastics, rubber, fibers, and coatings) and food contact grade (for food packaging materials, approved by regulations such as the US FDA, with strict controls on migration and hygiene indicators). Different grades of products have different purity and hygiene control requirements, with particular emphasis on the following indicators:

1. Melting point

Melting point is a standard factory inspection indicator that reflects the purity and quality of the product and must be controlled within the indicated range (approximately 110-125℃).

2. Volatile matter (loss upon heating)

Volatile matter reflects low-boiling-point impurities and moisture, which affect processing stability and product performance, and must be controlled within an extremely low range.

3. Ash

Ash content reflects the total amount of inorganic impurities, which affects product purity and product quality, and must be controlled within a reasonable range.

4. Light transmittance

Light transmittance (425nm/500nm) reflects the color and impurity content of a product and affects the quality of transparent products; therefore, high light transmittance must be maintained.

5. Solubility and Color

The product must dissolve well in organic solvents such as chloroform and benzene, with no obvious insoluble matter; color affects the initial coloring of the product, so a low color must be maintained.

6. Migration and health indicators

Food contact grade products must meet specific migration limits and hygiene and safety standards (such as FDA approval requirements) to ensure the safety of food contact.
