Introduction

Antioxidant 1010, also known as Irganox 1010, is a synthetic antioxidant used in various industries, including the food, plastics, and rubber industries. It belongs to a class of compounds known as phenolic antioxidants. Antioxidants are substances that can inhibit or delay the oxidation of other materials, which can help extend the shelf life of products and prevent degradation caused by exposure to oxygen and other environmental factors[1].

Application

Irganox 1010 is often used in the stabilization of materials like polymers (plastics and rubbers) and some food products to prevent the degradation and deterioration of their properties due to oxidation. It works by scavenging and neutralizing free radicals and other reactive species that can cause oxidative damage. In the food industry, it may be used as a food additive to prevent the spoilage of certain products and maintain their quality during storage and processing. In the plastics and rubber industry, it is used to improve the stability and longevity of materials that are exposed to environmental stressors, such as UV radiation and heat. It's important to note that the use of antioxidants in food products is regulated by food safety authorities in various countries, and their use must comply with established guidelines to ensure they are safe for consumption. Always follow the recommended guidelines and regulations when using antioxidants or any other food additives in food products or materials. Its primary function is to inhibit or delay the oxidation of materials, which can help prevent degradation and extend the shelf life of products. Here are some common applications of Antioxidant 1010[1]:

1.Plastics Industry: Antioxidant 1010 is widely used in the plastics industry to stabilize polymers and prevent them from undergoing oxidative degradation. Plastics can be susceptible to degradation when exposed to heat, oxygen, and UV radiation. This antioxidant helps protect plastic products, such as packaging materials, automotive parts, and more, from premature aging and deterioration.

2.Rubber Industry: In the rubber industry, Antioxidant 1010 is employed to enhance the stability and longevity of rubber products, including tires, hoses, seals, and various other rubber components. It helps mitigate the effects of heat and oxygen exposure, which can lead to cracking, hardening, and loss of elasticity in rubber materials.

3. Food Industry: Antioxidant 1010 is used as a food additive in the food industry to prevent the oxidation of fats and oils in food products. It helps extend the shelf life of items such as cooking oils, margarine, and processed foods, reducing rancidity and maintaining product quality.

4.Adhesives and Sealants: It is also utilized in adhesives and sealants to prevent degradation and ensure the long-term performance and reliability of these products.

5.Cosmetics and Personal Care Products: Some cosmetics and personal care products use Antioxidant 1010 to protect against oxidative changes, which can affect the color, scent, and overall quality of these items.

6.Polymers and Resins: It can be used in various polymer and resin applications, including coatings, paints, and other materials, to enhance their resistance to oxidative damage.

7.Lubricants: Antioxidant 1010 may be added to lubricants and oils to extend their service life and maintain their performance by reducing oxidation-related deterioration.

8.Textiles: In the textile industry, it can be used to protect synthetic fibers and fabrics from oxidative damage, helping to maintain their appearance and integrity.

It's important to follow recommended usage guidelines and regulations when using Antioxidant 1010 in these applications to ensure product safety and efficacy. The specific dosage and application methods can vary depending on the industry and product requirements. Manufacturers and users typically adhere to industry standards and regulations to achieve the desired results while maintaining safety and quality standards.

Synthesis

Pentaerythritol and β- (3,5-di-tert-butyl-4-hydroxyphenyl) propionate methyl ester, catalyzed by sodium methoxide, undergoes ester exchange reaction at 100-140 ℃ to obtain this product. Dimethylpentaerythritol and potassium tert butanol can also be used as catalysts, DMF as solvent, and prepared by reacting the above raw materials with a yield of 95.8%.

Safety

In the food industry, Irganox 1010 is often used as a food additive to prevent the spoilage and deterioration of certain products by inhibiting oxidation. The safety of its use as a food additive is regulated by food safety authorities in different countries, such as the U.S. Food and Drug Administration (FDA) in the United States and the European Food Safety Authority (EFSA) in the European Union. These regulatory bodies evaluate the safety of food additives, including antioxidants, through rigorous testing and assessment procedures. In the plastics and rubber industry, Irganox 1010 is used to stabilize materials against oxidation, heat, and other environmental stressors. Safety considerations may vary depending on the specific application and exposure to the substance. Manufacturers and users should follow guidelines and best practices to ensure safe handling and use of the antioxidant in these industrial applications. It's important to use antioxidant 1010 and other additives in accordance with recommended dosages and guidelines provided by regulatory agencies and industry standards. Additionally, if you have specific safety concerns or questions about the use of this antioxidant in a particular application, it is advisable to consult with relevant experts or regulatory authorities to ensure compliance with safety and quality standards.
