Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.
Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.
No direct listed-entry CAS match in this jurisdiction’s held reference set. This does not mean the material is allergen-free. Constituents, grouped entries and natural-material composition may require further review.
Finished-cosmetic declaration thresholds: greater than 0.001% leave-on; greater than 0.01% rinse-off. Apply the current target-market rules to the actual complete formulation; no concentration is inferred here.

Supplier certificates and private documents are separate evidence. Their availability does not determine whether this generic guide is shown. This is a dated local reference, not a live regulatory feed.
Use the listed solubility and preparation information to plan a small bench comparison with a known fragrance concentrate. Record clarity immediately and after standing; a clear sample alone does not establish compatibility or finished-product suitability.
Where the product specification supports the intended use, organise labelled working preparations for materials you already understand. Record the actual starting strength, carrier and preparation date so later comparisons describe the same material rather than different unrecorded dilutions.
Compare this preparation with an established reference while holding the fragrance concentrate and evaluation method constant. Record clarity and any observed change in the scent impression; treat the comparison as evidence to investigate, not proof of universal compatibility.

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.
For professional perfumery use only. Not for direct application to skin or ingestion. Keep out of reach of children.

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.
Products are supplied in accordance with our Documentation Supply Policy
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.
