About this material

Ambercore is a soft woody amber with a natural richness.

Used on its own or in combination with more expensive amber materials such as Ambroxan and Cedramber; it harmonises beautifully.

Perfect for blending with delicate Muguet and Citrus compositions, it can be used in large amounts, with a recommended use level of up to 40%, that is able to bring to life a natural spirit in all fragrance compositions.

Beautiful, velvety and delicate, similar to Cedramber, yet more cost effective.

Substantive and widely used for boosting the fragrance in detergent formulations.

Commonly used in Amber, Chypre, Citrus, Fern, Fougere, Muguet, Lily of the Valley and Oriental compositions.

For the untrained nose, Ambercore may be difficult to detect in isolation.

Fragrance allergen reference

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.

European Union / Northern Ireland

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.

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 this fragrance ingredient 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.

Creative ideas to explore

Creative directions, not tested formulas.

Woods in daylight

With bergamot and a crisp citrus opening

Explore a spare wood structure with citrus providing the opening contrast. Compare a brighter version with the wood reference and follow how the outline changes, keeping the later impression as important as the first moment.

A softer grain

With sandalwood and a musk direction

Set the woody material beside a softer wood reference, then compare a restrained musk variation. Decide whether your concept needs creamy texture, dry definition or more space between its parts before expanding the accord.

Petals on timber

With rose and a clear floral accord

Try a flower-and-wood study in which both subjects remain recognisable. Compare the floral reference with the woody variation through the evaluation, noting whether the wood forms a useful backdrop or becomes the centre of the idea.

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.

Products are supplied in accordance with our Documentation Supply Policy

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.
