Inactivents

Inactivents are substances that are added to a formulation but do not contribute to the intended therapeutic or active effect of the product. They are commonly found in pharmaceuticals, food products, and cosmetics. In pharmaceuticals, inactivents, often referred to as excipients, serve various purposes such as acting as fillers, binders, disintegrants, lubricants, or coatings in tablets and capsules. They can also be used to improve the stability, solubility, or bioavailability of the active ingredient. In food, inactivents might include preservatives, emulsifiers, colorants, or sweeteners that enhance the product's appeal, texture, or shelf life without being the primary nutritional or active component. Similarly, in cosmetics, inactivents can be emollients, humectants, or preservatives that contribute to the product's feel, performance, and longevity. The selection of inactivents is crucial and depends on the specific application and desired properties of the final product. They must be inert and safe for their intended use, meaning they do not react with the active ingredient or cause adverse effects in consumers. Regulatory bodies often oversee the use of inactivents to ensure product safety and quality.
