CAS numbers (comment): The scope of this Standard includes, but is not limited to the CAS number(s) indicated above; any other CAS number(s) used to identify these fragrance ingredients should be considered in scope as well.
Contributions from other sources: None to consider
Flavor use consideration: Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.
IFRA Standard type: RESTRICTION_SPECIFICATION
Intrinsic property driving the risk management measure: DERMAL SENSITIZATION
Restricted ingredients: notes: The above limits apply to Methyl ionone isomers used individually or in combination.
Specified ingredients: notes: Pseudo methyl ionones (CAS numbers 26651-96-7, 72968-25-3, 1117-41-5) should not be used as fragrance ingredient as such. A level of up to 2% of Pseudo methyl ionones as an impurity in Methyl ionones is accepted.

Creative ideas to explore
Creative directions, not tested formulas.
Petals and peel
With bergamot and a light citrus ideaExplore a brighter version of the floral character using a simple citrus counterpoint. Compare it with the unchanged flower accord and note whether the citrus frames the bloom or becomes the main subject of the sketch.
Stem and blossom
With geranium and leafy notesSketch the flower with a greener setting, keeping leaf and blossom as distinct ideas. Compare a clean floral reference with the greener version to decide how much of the imagined stem and garden belongs in the composition.
Petals over wood
With a transparent wood directionPlace the floral material against a spare wood backdrop and follow the balance through the evaluation. Try a softer wood variation separately, then choose whether your flower needs an open, airy setting or a smoother, more enveloping frame.

Dilution Information
MaterialFragrance ingredient
Carrier / solventAs specified for the product
Supplied dilutionCheck the ratio and carrier
Concept illustration only; no dilution ratio or carrier is implied for this material. Refer to the product specification and label.
The suffix D forms part of the product name and indicates that the material is supplied as a dilution rather than at full strength.
POD = Precious Oil Dilution, typically intended for aromatherapy applications.
AOD = Absolute Oil Dilution, indicating that the product is supplied as a diluted absolute.
The dilution ratio and carrier/solvent are stated within the product specification and will also be shown on the product label.
IMPORTANT: Customers should always rely on the product specification when confirming the concentration and carrier/solvent supplied.
While we endeavour to ensure that product names and suffixes accurately reflect the material supplied, the product specification (including the stated dilution ratio and carrier/solvent) shall take precedence in the event of any omission, abbreviation, naming variation, or delayed update to a product title.
Please ensure you have selected the correct material, concentration, dilution ratio and carrier/solvent before completing your purchase.
Handling precautions
For professional perfumery use only. Not for direct application to skin or ingestion. Keep out of reach of children.
Handle using the precautions specified for the material. Wear suitable protective gloves and eye protection where required.
Keep away from sources of ignition where applicable and avoid release to the environment.
Keep containers securely closed and store under the conditions specified on the product label and SDS. Keep liquid containers upright.
If swallowed or otherwise exposed, follow the SDS first-aid instructions and seek medical advice as appropriate. Do not induce vomiting unless directed by a medical professional.
Product-specific warnings, handling precautions and storage requirements take precedence over this general information.
Read the applicable SDS
A Safety Data Sheet (SDS) is available to logged in users who have purchased this item, where applicable.
Documents are not supplied before purchase.
Read the applicable SDS before handling or using the material. Follow its instructions for hazards, protective equipment, first aid, handling, storage and disposal.
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.
By proceeding with a purchase without prior written confirmation, you acknowledge and accept that documentation beyond the legally required SDS may not be supplied, and you agree that Perfume Extract shall not be held liable for the absence of such documentation or for any inability to complete regulatory requirements, including CPSR or product compliance obligations.

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.
