Though polymeric nanoparticles are often used in medical applications, they have the capability to be highly beneficial when used in other fields. One such field is the cosmetics industry. Many of the features of polymeric nanoparticles that make them useful for drug delivery also make them useful in formulations of makeup, perfumes, and creams.
In topical formulations, such as sunscreen or other creams, polymeric nanoparticles can be used to encapsulate active ingredients. This encapsulation allows for better penetration of the top layer of skin due to the small size of the particles. By penetrating the skin more effectively, the efficacy of the active ingredient is increased – whether it’s a UV protective agent, an anti-aging formula, or any other active ingredient. Encapsulation also creates the potential for extended release of active ingredients. This is advantageous for long-wear cosmetics. In sunscreen, it allows for maintained potency with fewer applications. Similarly, in makeup or perfume, as the nanoparticles degrade throughout the day, pigment or fragrance can be released. This eliminates the need for reapplication.
