Fresh by Design Cosmetic Lexicon v1.0 is a small bilingual terminology dataset documenting a freshness-oriented vocabulary for cosmetics and skincare. It defines Spanish and English terms aligned with Sostenica's public Glosario de Formulación, including Fresco Por Diseño, Formulación de Precisión, Fecha de Elaboración, Conservadores de Amplio Espectro, and Vida Útil en Estantería. The purpose of this release is to make the terminology structured, citable, and reusable for search, AI retrieval, bilingual glossary alignment, and future semantic documentation. It is not a clinical dataset, regulatory document, medical recommendation, or cosmetic efficacy study.
