About this material

Discover the luminous elegance of Cassis Base 345 B, a signature creation from Firmenich that captures the vivid, multi-faceted character of blackcurrant in its most refined form.

This speciality base material recalls the green, fruity, floral nuance of blackcurrant buds, beautifully intertwined with the crisp freshness of the boxwood shrub—creating an aroma that is both vibrant and sophisticated.

Diffusive and effulgent, Cassis Base 345 B is an all-natural proprietary blend, designed to bring radiance and lift to fine fragrance compositions.

Its profile opens with a juicy, tangy brightness, evolving into leafy green undertones and a delicately floral heart, before settling into a soft, elegant warmth.

Reminiscent of Blackcurrant Buds Absolute, this base goes further—evoking not only the richness of blackcurrant but also subtle hints of blackberry, adding depth and intrigue to its fruity signature.

The result is a versatile and highly expressive material that lends authenticity and modernity to any creation.

Ideal for niche perfumery and luxury accords, Cassis Base 345 B enhances floral bouquets, energises fruity compositions, and adds a naturalistic green edge to woody or gourmand blends.

Its exceptional diffusion and lasting presence ensure a memorable olfactory impact.

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.

Documentation Supply Policy

IFRA formulation guide

Generic reference only — not an IFRA certificate, compliance decision or use recommendation. The Responsible Person and qualified safety assessor must assess the actual finished formula using current applicable IFRA Standards, supplementary documentation where available and the CPSR.

Source: 51st Amendment overview, held source checked 2026-10-21. Bundle 2026-10-27. Individual Standards prevail over the overview.

No direct IFRA overview entry matched the recorded CAS in this held dataset. This does not mean unrestricted use, absence of relevant Standards or compliance. Constituent restrictions may still apply.

IFRA source overview · Individual IFRA Standards and supplementary documentation

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.

Creative ideas to explore

Creative directions, not tested formulas.

Leaf and blossom

With rose and garden florals

Explore a green floral sketch around a clear flower reference. Compare the leafy accent with the flower alone and decide whether the scene suggests a cut stem, a growing garden or a greener abstraction you want to develop.

Peel and leaf

With bergamot and herbal directions

Use citrus as a bright setting for the green material, then try an herbal alternative as a separate variation. Keeping those contrasts apart makes it easier to choose between a peel-focused idea and a leafy cologne.

A shaded wood

With transparent woods and soft musk

Sketch a green wood direction with a restrained backdrop. Follow the leafy character as the study develops, comparing a wood-only reference to decide whether the scene suggests fresh branches, shaded timber or a softer woodland impression.

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.

Document scope and limitations

The supplementary documents currently available for this material are identified in this tab. Availability varies between materials.

Batch-specific certificates, analytical results and additional technical data are not guaranteed. They are supplied only where their availability is expressly confirmed in this tab or separately confirmed by us in writing.

Where provided, supplier IFRA documentation does not replace a comprehensive safety assessment or constitute approval of a finished formulation. Customers must consider their complete formulation and intended application.

Any linked IFRA standard is provided for reference and is not a batch-specific specification or analytical certificate for the material supplied.

Do not assume that documentation confirms a particular batch, residual constituent level, manufacturing process or analytical result unless it expressly states this.

The same limitations apply to allergen declarations, Certificates of Analysis (CoAs), technical data sheets, specifications, and other regulatory, analytical or compositional documents. These documents provide information only within their stated scope; they do not replace a comprehensive safety assessment or constitute approval of a finished formulation, nor do they guarantee suitability for a particular application. Customers must assess their complete formulation and intended use.

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.
