Formulations refer to the specific combinations of ingredients or components used to create a product, particularly in industries like pharmaceuticals, cosmetics, and food. These mixtures are carefully designed to achieve desired properties, such as stability, effectiveness, and safety. For example, a pharmaceutical formulation may include active ingredients, excipients, and preservatives to ensure the medicine works properly and remains safe for consumption. In the context of cosmetic formulations, various substances are blended to create lotions, creams, and makeup products. The formulation process involves selecting the right ingredients to provide benefits like hydration, sun protection, or color. Each formulation is tested for quality and performance to meet regulatory standards and consumer expectations.
