Researchers at Belgorod State National Research University (NRU BelSU) have unveiled a process to produce multi colored anthocyanin dyes in dry encapsulated forms with pronounced antioxidant activity. This development targets cosmetic applications such as lipsticks and cream shadows, offering a natural alternative to conventional synthetic colorants. Initial demonstrations include natural lip products that combine strong antioxidant protection with impressive coverage and pigmentation.
Anthocyanins are water soluble flavonoids that give pink, red, purple, and blue hues to many fruits, vegetables, roots, and flowers. They are non toxic and serve as natural colorants that can be extracted from plant material for diverse uses. At present, natural anthocyanin dyes are not manufactured domestically in Russia and are typically sourced from international suppliers, often fetching high per‑kilogram costs. A domestic alternative would substantially reduce cost, with estimates suggesting prices could be at least one third of foreign equivalents if mass produced locally.
Industry experts highlight anthocyanins as promising ingredients across multiple sectors, including food, cosmetics, and health care. They function as potent antioxidants capable of neutralizing free radicals, a property that contributes to potential benefits in cardiovascular health, cognitive aging, and certain cancers according to research cited by industry specialists. The encapsulation approach enhances stability and shelf life, enabling reliable incorporation into formulations that require consistent color and performance. In this context, the production process emphasizes environmental responsibility by using dilute mineral and organic acids and ethyl alcohol for extraction, with opportunities to recycle solvents through distillation during dye recovery. This aligns with a broader push toward sustainable materials in cosmetic manufacturing, where natural pigments intersect with advanced delivery systems to improve product safety, efficacy, and consumer appeal. The knowledge base around anthocyanins continues to expand, with ongoing investigations into optimization of extraction methods, pigment stability under light and heat, and the health implications of long‑term consumption or topical use. Researchers note that while the primary application discussed here is cosmetic, the same basic chemistry underpins a wide range of edible and therapeutic contexts, reinforcing the material’s versatility and market potential.
