About this material
Citral is a naturally occurring organic compound classified as a terpenoid.
It’s best known for its strong lemon-like aroma and is a major component in the essential oils of several plants, especially lemongrass, lemon myrtle, and citrus fruits.
It is an unsaturated aldehyde that exists as a mixture of two geometric isomers:
- Geranial (citral A) has a strong lemon scent.
- Neral (citral B) has a slightly sweeter, less intense lemon odour.
Used extensively in perfume to impart citrus notes and as a starting material for synthesising other compounds like Ionones, and Methyl Ionones (important in fragrance chemistry).
It is also used as an antimicrobial agent in natural medicine.
A solid alternative that may be considered in place of this classic Lemon material is Citroasis Base by Firmenich.

Creative ideas to explore
Creative directions, not tested formulas.
A leafy cologne
With geranium and herbal notesSketch a citrus opening with a green or herbal counterpoint. Compare the leafy version with the citrus alone, noting whether the added direction suggests peel, garden freshness or an herbal character that changes the brief.
Citrus and grain
With a transparent wood directionExplore a spare citrus-and-wood structure, keeping the wood choice simple. Follow both the opening and later impression to see whether the composition keeps a clear outline as the bright citrus character changes through the evaluation.
Petal brightness
With rose and airy floral notesUse a familiar floral accord as the setting for a brighter citrus variation. Compare the flower with and without the citrus material, then decide whether to emphasise a fresh opening or a more continuous floral impression.

An SDS provides information about the material supplied; it does not replace an assessment of the safety or compliance of a finished formulation.
Please note that supplementary documentation—including, but not limited to, IFRA Certificates, Certificates of Analysis (CoA), Allergen Declarations, and other regulatory or compositional data—may not be available for all products. Refer to the "Supplementary Documentation" tab to check current availability. If the tab is not present, no supplementary documents are available for the material.
Customers intending to use materials in cosmetic applications, including for the preparation of a Cosmetic Product Safety Report (CPSR) under UK and EU Cosmetics Regulations, must contact us prior to purchase to confirm the availability and suitability of any required documentation where it is not explicitly stated. Orders must not be placed in reliance on the assumption that such documentation will be provided where it is not explicitly stated on the relevant product page at the time of purchase.

Customer responsibility
These limitations apply to reliance on all documentation supplied, including IFRA information, allergen declarations, Certificates of Analysis (CoAs), technical data sheets, specifications and other supporting documents.
Perfume Extract is solely a reseller of this product and is not an agent, official distributor, or affiliated in any way with the manufacturer.
Customers are responsible for determining whether the material and available documentation meet their requirements before purchase, and for assessing the safety and compliance of their finished products.
We do not provide formulation instructions, formulation consultancy or confirmation of suitability at a particular concentration or for a particular application.
Producer identity, detailed sourcing and processing information are not disclosed beyond the information published in the product listing.
Please read our Documentation Supply Policy alongside the product specification and available documentation.
Synonyms, alternative names, CAS/EC references, botanical names, manufacturer references and external links may describe a substance or material family generally. They should not, on their own, be taken as confirmation of the supplied material’s producer, geographical origin, manufacturing process, grade, purity, constituent levels or batch characteristics.
In particular, a synonym or reference must not be used to infer that a material is free from a particular constituent, meets a numerical specification, or is suitable for a particular application or concentration.
IFRA information, allergen declarations, Certificates of Analysis (CoAs), technical data sheets and other supporting documents apply only within their expressly stated scope. A general specification or reference document is not a batch-specific analytical result unless it expressly identifies the relevant batch.
If information appears inconsistent, or a particular characteristic is essential to your purchase, contact us for written clarification before ordering. Do not resolve discrepancies by assuming that a synonym, external reference or document for another grade applies to the material supplied.
We do not confirm characteristics beyond those expressly supported by the applicable product specification or our written confirmation. Customers remain responsible for assessing their complete formulation and intended application.
Nothing in this information excludes or restricts liability or statutory rights that cannot lawfully be excluded or restricted.
