Triethyl citrate is a wonderful natural (US & EU) diluent for perfumery. It is naturally extracted with pure food grade alcohol from citric acid from citrus fruit. Triethyl Citrate (TEC) has no odour and allows for dilutions of natural materials that maintain an ISO 9235 standard. TEC is particularly good as a diluent for rose materials and bases and it is widely used in the fragrance industry in both synthetic and natural versions. TEC has excellent solubility in alcohol as well as fractionated coconut oil. It also solubilises in jojoba oil but may cause slight cloudiness. Always perform a small test to ensure compatibility as solubility can vary from medium to medium and depends upon the overall blend of materials in play.
