Triethyl Citrate (TEC) is a colorless, nearly odorless, biodegradable organic ester derived from citric acid and ethanol. It is widely used in the fragrance, cosmetics, pharmaceutical, food, and industrial sectors as a solvent, plasticizer, and fixative. In the perfume and cosmetics industry, TEC is primarily used as a fragrance fixative and solvent. It helps dissolve fragrance ingredients, improves the stability of perfume formulations, and slows the evaporation of volatile fragrance components, resulting in a longer-lasting scent. Due to its low toxicity, mild odor, and phthalate-free composition, Triethyl Citrate is a preferred alternative to traditional phthalate-based fixatives in many modern fragrance formulations. In perfume formulations, Triethyl Citrate (TEC) serves several important functions:
Fragrance Fixative: Slows the evaporation of volatile fragrance components, helping the scent last longer on the skin.
Solvent: Dissolves fragrance ingredients and essential oils, creating a clear, homogeneous formulation.
Fragrance Stabilizer: Improves the stability of fragrance compositions and helps maintain the intended scent profile over time.
Diluent/Carrier: Acts as a carrier for fragrance oils, making them easier to blend and incorporate into perfume formulations.
Low-Odor Base: Has a very mild odor, so it does not interfere with the perfume's fragrance.
Phthalate-Free Alternative: Commonly used as a safer, biodegradable substitute for diethyl phthalate (DEP) in perfumes.
Benefits in Perfume:
Extends fragrance longevity.
Improves fragrance stability.
Enhances blending of fragrance ingredients.
Provides a non-flammable, low-toxicity alternative to traditional fragrance solvents and fixatives.
Supports clean-label and phthalate-free formulations.
