Bulk citronella oil quality starts with one number: citronellal content. A drum labeled citronella oil can carry anywhere from the low teens to the mid forties in citronellal percentage depending on the botanical variety, the harvest, and how the distillation was run. Buyers who order on the product name alone, without a GC-MS report stating that number, have no way to know which end of that range they received, or whether the lot will perform in a repellent candle, a soap base, or a fragrance compound the way the previous shipment did.<\/p>\n
The gap shows up fast once a lot reaches production. Candle and repellent manufacturers need a citronellal floor to support an active-ingredient claim on the label, cosmetic formulators need a stable terpene profile batch to batch, and perfumers building outdoor fragrance accords need to know whether they are working with Java type oil or Ceylon type oil before they set a dosage. This guide covers what citronellal content actually tells a buyer, how it gets verified, what the EU allergen rules mean for geraniol and citronellol in the same oil, and which documents to request before a first container order.<\/p>\n
\t\t\t\t\t\t\t\t Have your target citronellal range, order volume, and destination market ready when you request pricing on citronella essential oil<\/a>. Our export team can confirm current lot specifications and lead times against those details directly.<\/p>\n Citronellal is the aldehyde that gives citronella oil most of its repellent character and its sharp, lemony top note, and the percentage of it in a given lot is what separates a fragrance-grade oil from a filler-grade one. Most trade specifications set citronellal somewhere between 35 and 45 percent in Java type oil, alongside a combined geraniol, citronellol, and citronellal floor often referenced near 85 percent.<\/p>\n Two botanical sources sell under the same citronella oil name, and they do not share one citronellal number. Cymbopogon winterianus<\/em>, the Java type grown widely across India and Indonesia, runs higher in both geraniol and citronellal and is the type most bulk fragrance and candle buyers specify. \u30b7\u30f3\u30dc\u30dd\u30b4\u30f3\u30fb\u30ca\u30eb\u30c9\u30a5\u30b9<\/em>, the Ceylon type native to Sri Lanka, carries a lighter, greener profile with a different balance of the same constituents. A buyer who does not confirm which species is in the drum is comparing two different raw materials under one label, a distinction covered in more depth in our comparison of Java and Ceylon citronella oil<\/a>.<\/p>\n A GC-MS report is the only reliable way to confirm citronellal content, since appearance and aroma alone cannot distinguish a 35 percent lot from a 25 percent one. Reputable exporters run gas chromatography-mass spectrometry on every production batch and issue a certificate of analysis that states the citronellal, geraniol, and citronellol percentages for that specific lot, not a generic average for the product line.<\/p>\n \t\t\t\t\t\t\t\t\t\t\t\t\t The certificate of analysis should list the lot number, the test date, and the individual percentages for the major constituents alongside physical checks such as relative density, refractive index, and optical rotation. Buyers who want to understand how to read those figures, rather than take a suppliers word for a passing result, can work through our guide on reading a bulk essential oil COA and GC-MS report<\/a>. A supplier who cannot produce a batch-specific report, and offers only a generic specification sheet instead, is not in a position to support a repeat order at a consistent grade.<\/p>\n Geraniol and citronellol, two of the same constituents that define citronellal grade, both appear on the European Unions list of fragrance allergens that require label disclosure above a set threshold. Under Regulation (EC) No 1223\/2009<\/a>, Annex III, either substance must be named on the product label once it exceeds 0.001 percent (10 ppm) in a leave-on cosmetic or 0.01 percent (100 ppm) in a rinse-off product.<\/p>\n Because Java type citronella oil commonly carries a significant geraniol share alongside its citronellal, a cosmetic formulator working close to those thresholds needs the exact percentage from the batch certificate, not a published range, to calculate the finished-product disclosure correctly. Buyers shipping into the EU should request the allergen breakdown alongside the GC-MS report rather than assume the listed typical figures apply to their specific lot. A fuller look at how these thresholds apply across the catalog is available in our guide to EU fragrance allergen labeling rules<\/a>.<\/p>\n Not every buyer category needs the same citronellal floor, and knowing which one applies to a given order avoids paying for a specification the end use does not require. Insect-repellent and candle manufacturers generally need the highest, most consistent citronellal share, since it drives both the scent throw and the active-ingredient claim on the label.<\/p>\n Candle and wax melt producers, in particular, test incoming oil for flash point and cold-throw performance alongside citronellal content, since a low-grade lot can smell acceptable in the bottle and still underperform once poured into wax. Our notes for that segment are covered in what candle and wax melt manufacturers verify in bulk essential oils<\/a>.<\/p>\n Soap makers and personal care formulators tend to work with a wider acceptable range, since the oil is one note in a blended fragrance rather than the active ingredient, but they still check the allergen disclosure covered above before finalizing a cold process recipe. Buyers moving into that category can review how soap makers source bulk essential oils for cold process batches<\/a> for the related sourcing checklist. Perfumery houses sit between the two, usually requesting a higher geraniol-to-citronellal ratio for a rounder, rosier note rather than the sharper profile candle and repellent buyers prefer.<\/p>\n Bulk citronella oil ships in the same tiers as most essential oils we export: sample quantities, under 5KG tins, 5 to 25KG drums, 25 to 100KG drums, and 100KG-plus for container volume. Orders large enough to fill a significant share of a container often move more economically in a flexitank than in individual drums, a tradeoff covered in drums vs flexitanks for bulk essential oil packaging<\/a>.<\/p>\n
