About this material

Diethyl Phthalate is a low-odour solvent used as a practical formulation material.

Its role is to support a composition by providing a carrier for compatible fragrance ingredients, allowing evaluation and handling at a chosen working concentration.

For a perfumer, the value of a carrier lies in how it supports practical work with the chosen ingredients.

A low-odour carrier should still be assessed in context.

Changes to solvent balance can influence clarity, handling and the way a composition is evaluated; compatibility cannot be assumed to be identical for every fragrance ingredient or application.

Check the intended mixture after standing, rather than treating initial clarity as a complete stability assessment.

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.

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.

A clear starting point

With Diethyl Phthalate (DEP) and a known concentrate

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.

A dilution library

Labelled samples and repeatable records

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 the carrier

One concentrate, controlled variables

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.

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.
