Bulk lemongrass oil buyers rarely reject a shipment over price. They reject it because the citral content on the certificate of analysis does not match the specification they ordered against, or because the GC-MS fingerprint does not resemble the plant it claims to come from. This guide sets out what citral content measures, how the two commercial lemongrass species differ, and which documents a buyer should request before committing to a bulk order.<\/p>\n
India supplies most of the world’s Cymbopogon flexuosus, the East Indian lemongrass species that flavor, fragrance, and personal care manufacturers specify most often today. A shipment that reads high in total citral but shows an inconsistent chromatography profile can still fail a formulator’s incoming inspection, delay a production run, or get held up at customs. Understanding the compound behind the number, and the standards bodies that define it, turns a generic purchase order into a specification a supplier can be held to.<\/p>\n
\t\t\t\t\t\t\t\t Buyers ready to move from specification to purchase order should have the target citral range, the intended finished product category, and the destination market on hand when they contact our export team about lemongrass essential oil<\/a>.<\/p>\n Citral is the combined measure of two isomers, geranial and neral, and it is the compound responsible for lemongrass oil’s sharp, lemon-forward aroma. Citral percentage is the single figure most buyers use to grade a shipment, because it correlates directly with aroma strength, flavor intensity, and how much oil a formulator needs to hit a target scent or flavor profile.<\/p>\n A higher citral reading generally means a stronger, cleaner lemon note and a lower use rate in the finished formulation. Buyers grading a shipment should look beyond the headline percentage and confirm:<\/p>\n The same logic applies across other marker-compound-graded oils in our catalog. Bulk carrot seed oil<\/a>, for example, is graded largely on its carotol content, following a similar quality framework.<\/p>\n Two species supply nearly all commercial lemongrass oil, and buyers who do not specify which one they need risk receiving an oil that smells and performs differently than expected. Cymbopogon flexuosus, known as East Indian lemongrass, is the species most Indian exporters supply and typically carries the higher citral content.<\/p>\n \u306b\u4f7f\u7528\u3055\u308c\u3066\u304d\u307e\u3057\u305f\u3002 ISO 4718 standard<\/a> covers oil of lemongrass from Cymbopogon flexuosus, while a separate standard covers Cymbopogon citratus, the West Indian species grown mainly in Central America and parts of Africa. East Indian lemongrass oil commonly tests in the 80 to 85 percent citral range, giving it a sharper, more concentrated lemon character that flavor and fragrance houses often prefer for cost-in-use reasons. West Indian lemongrass tends to run slightly lower in citral with a softer, greener background note. A purchase order that names the species and cites the relevant ISO standard removes most of the ambiguity that leads to a rejected lot.<\/p>\n Distillers produce nearly all commercial lemongrass oil by steam distillation of fresh or partially wilted leaves, and the interval between harvest and distillation has a measurable effect on citral yield. Grass that sits too long before processing loses volatile aldehydes to oxidation, lowering the final citral reading even when the plant material itself was high quality.<\/p>\n Distillers who process grass within a day or two of cutting, and who avoid excessive heat or prolonged distillation times, typically deliver more consistent lot-to-lot citral levels. Buyers sourcing on a recurring basis benefit from asking a supplier about harvest-to-still turnaround time and whether the same growing region supplies successive lots, since grass genetics also shift the profile a chromatography report will show.<\/p>\n The same genus produces palmarosa oil, another grass distillate graded on its own marker compound. Buyers already sourcing bulk palmarosa oil<\/a> from India can generally expect a similar level of process discipline from a lemongrass supplier.<\/p>\n A certificate of analysis lists physical properties such as specific gravity, refractive index, and optical rotation alongside the citral percentage, but the GC-MS report confirms the oil matches its claimed species and has not been diluted or adulterated. Buyers should request both documents for every lot, not just a standing product data sheet.<\/p>\n \t\t\t\t\t\t\t\t\t\t\t\t\t A useful GC-MS report shows the full chromatography peak profile, not only the summary percentage, so a buyer’s quality team can compare the fingerprint against a known-authentic reference. Consistency across shipments matters as much as the individual percentage: a supplier whose GC-MS fingerprint shifts noticeably between lots is either sourcing from different growing regions or blending, and either fact belongs on the paperwork. Peer-reviewed chemical composition studies<\/a> on Cymbopogon citratus and Cymbopogon flexuosus back up why total citral alone is an incomplete quality signal without the supporting fingerprint.<\/p>\n Citral carries a known potential for skin sensitization, so IFRA’s citral standard<\/a> sets maximum allowable concentrations for citral-containing materials such as lemongrass oil across its full set of product exposure categories, with tighter limits for leave-on skin products than for rinse-off or non-skin-contact items.<\/p>\n A cosmetic brand formulating a leave-on lotion or a fine fragrance needs to calculate the citral contribution from every raw material in the formula, including lemongrass oil, and stay under the applicable category limit. Buyers should ask suppliers for a current IFRA conformity certificate alongside the standard COA and GC-MS report, since IFRA amends its standards periodically and an older certificate may not reflect the latest limits. This is a formulation and compliance requirement, not a statement about the safety of lemongrass oil in its raw form, and buyers should always confirm current limits directly against IFRA’s published standard before finalizing a formula.<\/p>\n Bulk lemongrass oil moves into three main buyer categories: flavor manufacturers using it in beverages and confectionery, fragrance and personal care brands using it in soap, cosmetics, and household products, and manufacturers of insect-repellent formulations that value its natural profile.<\/p>\n Readers comparing sourcing options across the wider catalog can browse our essential oils category<\/a> for related buyer guides.<\/p>\n Bulk lemongrass oil ships in food-grade or UN-approved drums for full container loads, or in smaller lined pails and jerricans for trial and sample orders, with export documentation including a certificate of origin, COA, GC-MS report, SDS, and TDS accompanying every shipment.<\/p>\n
