Additives are chemicals or substances added to products to improve their properties, performance, or appearance. They are widely used in various industries, including food, cosmetics, pharmaceuticals, and materials science. In this article, we will explore seven common types of additives, their functions, and applications, presented in a structured format with a table and subheadings.

Introduction

Additives play a crucial role in enhancing the quality and functionality of products. They can improve taste, texture, color, shelf life, and other desirable characteristics. Understanding the types and functions of additives is essential for manufacturers, consumers, and regulators alike.

The Seven Common Additives

• 1. Preservatives

Function: Prevent spoilage and microbial growth, extending shelf life.

Examples: Sodium Benzoate, Potassium Sorbate, Benzalkonium Chloride.

Applications: Food, cosmetics, pharmaceuticals.

• 2. Antioxidants

Function: Prevent oxidation, maintaining freshness and nutritional value.

Examples: Ascorbic Acid (Vitamin C), Tocopherols (Vitamin E), Butylated Hydroxyanisole (BHA).

Applications: Food, cosmetics, pharmaceuticals, coatings.

• 3. Emulsifiers

Function: Allow oil and water to mix, improving texture and consistency.

Examples: Lecithin, Mono- and Diglycerides, Polysorbate 80.

Applications: Food, cosmetics, pharmaceuticals.

• 4. Colorants

Function: Add or restore color to products.

Examples: Tartrazine (Yellow 5), Carmine (Red 4), FD&C Dyes.

Applications: Food, cosmetics, textiles.

• 5. Flavorings

Function: Enhance or modify the taste and aroma of products.

Examples: Vanilla Extract, Monosodium Glutamate (MSG), Artificial Sweeteners.

Applications: Food, beverages, pharmaceuticals.

• 6. Texturizers

Function: Improve the texture and mouthfeel of products.

Examples: Xanthan Gum, Carrageenan, Modified Starches.

Applications: Food, cosmetics, personal care products.

• 7. UV Absorbers

Function: Protect products from UV degradation, extending lifespan.

Examples: Benzotriazoles, Benzophenones, TEGO® Rad.

Applications: Coatings, plastics, cosmetics.
