Cosmetic formulation is the process of creating products designed for personal care and beauty, such as lotions, creams, and makeup. This involves selecting and combining various ingredients, including emollients, preservatives, and fragrances, to achieve desired properties like texture, stability, and effectiveness. Formulators must consider factors like skin type, product safety, and regulatory guidelines during development. They often conduct tests to ensure that the final product is safe for use and meets consumer expectations. The goal is to create effective and appealing products that enhance personal appearance and well-being.
