Additive substances, also known as additives, are compounds that are added to a product to improve its properties or to achieve a specific effect. They are commonly used in various industries, including food, pharmaceuticals, cosmetics, and materials science. Additives can serve multiple purposes, such as enhancing stability, improving texture, extending shelf life, or providing specific functional benefits.

In the food industry, additives are used to preserve food, improve taste, and extend shelf life. Common food additives include preservatives like sodium benzoate, antioxidants like butylated hydroxytoluene (BHT), and emulsifiers like lecithin. These substances help maintain the quality and safety of food products.

In the pharmaceutical industry, additives are used in the formulation of drugs to improve their stability, solubility, and bioavailability. Examples include excipients like starch, lactose, and magnesium stearate, which are used to fill tablets and capsules.

In the cosmetics industry, additives are used to enhance the texture, stability, and performance of products. Common cosmetic additives include emulsifiers, thickeners, and preservatives. These substances help create products that are effective, safe, and pleasant to use.

In materials science, additives are used to modify the properties of materials, such as plastics, ceramics, and metals. For example, plasticizers are added to plastics to make them more flexible, and fillers are added to ceramics to improve their strength and durability.

The use of additives is regulated to ensure their safety and effectiveness. Regulatory bodies, such as the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), establish guidelines and standards for the use of additives in various industries. These regulations help ensure that additives are safe for consumers and that they are used responsibly.
