Cymbopogon flexuosus is a citral desk. Citral is neral plus geranial; the isomer ratio changes the blotter, and citral oxidises. Last season’s typical is literature, not this drum. C. citratus is a different botanical.
Cymbopogon winterianus (Java citronella) is a citronellal desk. The enquire typical sits around 30%. Ceylon type (C. nardus) is another oil. This site does not sell a backyard spray.
Cymbopogon martinii (palmarosa) is high geraniol. Using it to extend rose otto ruins both briefs. Geranyl acetate is why two lots with the same geraniol % smell different. Rose lives on the sourced-to-brief page, not here.
The three lines: lemongrass, citronella, palmarosa. Do not write “Cymbopogon oil” on a purchase order.
