Citral

Citral (CAS 5392-40-5) is a naturally derived aldehyde available under trade names including Citral 95, Citral 82, Lemsyn GB, Lemarome N, and Citral PQ Extra. It carries no assigned E-code and is classified under HS code 29121900. The compound occurs as a mixture of two geometric isomers, geranial and neral.

In fragrance formulation, citral delivers a sharp lemon character and serves as a direct precursor to ionones and other aroma chemicals synthesised through condensation reactions. In hair conditioner systems, it functions as an antimicrobial agent and fragrance contributor, acting against specific yeast and bacterial strains at low use concentrations.

Citral is sourced in multiple grades, including 82% and 95% purity variants, to suit food-grade and cosmetic applications respectively. It complies with REACH registration requirements and is evaluated under FCC standards for flavour use. Suppliers typically offer drum and IBC packaging for B2B procurement.
