SDA 39-C is a premium specially denatured ethanol developed for professional cosmetic and fragrance manufacturing. It combines the excellent solvency and rapid evaporation of high-purity ethanol with a denaturing system that complies with U.S. regulatory requirements, allowing its use in non-beverage products such as perfumes, colognes, deodorants, lotions, creams, soaps, and other personal care formulations.

Its outstanding clarity, low residue, and compatibility with fragrance oils make it an excellent choice for manufacturers seeking consistent product quality and reliable formulation performance. SDA 39-C continues to be widely used throughout the cosmetic industry, while SDA 40-B has become the preferred option for many premium perfume manufacturers due to its modern denaturing system and minimal influence on fragrance character.

Difference Between SDA 39-C and SDA 40-B
