Dihydro Coumarin – Tonka Bean, Creamy Coconut & Sweet Tobacco Fragrance Enhancer | Perfume Grade Aroma Chemica

Short Description

Dihydro Coumarin is a sophisticated and versatile aroma chemical celebrated for its beautifully smooth tonka bean character, creamy coconut nuances and distinctive sweet, warm fragrance profile.

Combining the comforting aroma of sweet hay, soft vanilla, creamy coconut, delicate almond and subtle tobacco undertones, Dihydro Coumarin introduces warmth, richness and elegance to fragrance compositions.

Particularly valuable in fougère perfumes, gourmand fragrances, tobacco accords, coconut compositions, vanilla perfumes and sophisticated woody ambers, Dihydro Coumarin is an excellent ingredient for perfumers looking to create smooth, warm and beautifully rounded fragrance structures.

Unlike traditional Coumarin, Dihydro Coumarin contributes a softer, more lactonic and creamy impression, making it especially useful in modern gourmand and sophisticated unisex fragrances.

Supplied as a 10% ready-to-use solution in Di propylene Glycol (DPG) for convenient and controlled fragrance formulation.

What Is Dihydro Coumarin?

Dihydro Coumarin (CAS: 119-84-6), also known as 3,4-Dihydrocoumarin, Chroman-2-one or Melilotic Lactone, is a long-lasting aroma chemical used in professional fragrance development.

It belongs to the lactone family and is chemically related to Coumarin, one of the classic materials responsible for the sweet hay and tonka bean character found in traditional perfumery.

Its distinctive fragrance profile combines warm tonka bean, soft vanilla, creamy coconut, fresh hay, subtle almond and delicate tobacco-like nuances.

While Coumarin is especially recognized for its sweet hay, tonka and powdery almond character, Dihydro Coumarin provides a creamier interpretation with a more noticeable coconut and lactonic quality.

This makes it particularly valuable in compositions where a perfumer wishes to combine traditional coumarinic warmth with modern creamy gourmand effects.

Dihydro Coumarin is useful in classic fougère perfumes, where it supports lavender, aromatic herbs and woody materials.

It also performs beautifully in warm tobacco, creamy sandalwood, coconut, vanilla, caramel and sophisticated amber compositions.

Its excellent substantivity allows it to contribute a persistent sweet, creamy and coumarinic character to the fragrance dry-down.

Because it possesses a distinctive warm sweetness, careful balancing is recommended to avoid overpowering delicate floral or fresh compositions.

Typical Uses

Tonka Bean Accords

Dihydro Coumarin is particularly valuable for building sophisticated tonka bean fragrance effects.

Its sweet, warm and coumarinic character contributes the characteristic comforting impression associated with tonka-inspired perfumes.

When combined with Coumarin, Vanillin, Heliotropin and suitable woody materials, it creates a fuller, smoother and more complex tonka accord.

The creamy coconut undertone adds an attractive softness to compositions that might otherwise smell excessively dry or powdery.

Coconut & Creamy Fragrances

One of Dihydro Coumarin's most useful characteristics is its subtle creamy coconut effect.

Unlike strongly fruity coconut lactones, Dihydro Coumarin contributes a softer coconut impression combined with vanilla and tonka warmth.

When blended with Gamma Octalactone, Aldehyde C-18, Vanillin and creamy musk materials, it can help create luxurious coconut milk, coconut cream and tropical gourmand accords.

This makes it particularly valuable when a coconut fragrance requires a smooth, elegant character rather than an excessively sweet tropical effect.

Classic Fougère Fragrances

Coumarinic materials are fundamental to the traditional fougère fragrance family.

Dihydro Coumarin introduces smooth hay-like sweetness and aromatic warmth that complements lavender, bergamot, oakmoss and woody materials.

Its creamy character can soften the transition between fresh aromatic opening notes and deeper woody base materials.

It is particularly useful for developing sophisticated masculine fragrances with a modern, rounded fougère character.

Tobacco-Inspired Fragrances

Dihydro Coumarin is an excellent supporting ingredient in sweet tobacco-inspired fragrance compositions.

Its warm hay, vanilla, tonka and subtle tobacco nuances complement woody, amber and balsamic materials.

When combined with Coumarin, Vanillin, Benzoin, Iso E Super and suitable woody ingredients, it contributes to the impression of sweet aromatic tobacco.

Small amounts of Cyclotene can introduce additional roasted and caramelized warmth where desired.

Vanilla & Gourmand Fragrances

Dihydro Coumarin adds creamy warmth and sophistication to vanilla compositions.

While Vanillin provides the primary vanilla aroma, Dihydro Coumarin contributes a complementary tonka, coconut and soft almond dimension.

This combination is particularly effective in creamy vanilla, almond milk, warm dessert and sophisticated gourmand fragrances.

It can also soften highly sweet accords by introducing a more rounded, aromatic character.

Almond & Powdery Fragrances

Its subtle almond-like character makes Dihydro Coumarin useful in soft powdery fragrance compositions.

When combined with Heliotropin, Benzaldehyde, Vanillin and clean musks, it can help create smooth almond-powder accords.

Its creamy character makes it especially valuable in comforting, cosmetic-inspired fragrances.

Woody Amber Fragrances

Dihydro Coumarin combines beautifully with woody and amber materials.

When blended with Iso E Super, Ambroxan, Cedryl Acetate and Benzoin, it introduces a warm, sweet and creamy contrast to dry woody base notes.

This is particularly useful in sophisticated masculine and unisex perfumes requiring a balance between woody dryness and comforting warmth.

Sandalwood Fragrances

Creamy sandalwood materials combine particularly well with Dihydro Coumarin.

When paired with Sandenol, Javanique™, Iso E Super and clean musks, it can enhance the creamy impression of a sandalwood accord.

Its subtle tonka and coconut nuances add warmth and complexity without requiring a strongly sweet gourmand structure.

Chypre & Aromatic Fragrances

At carefully controlled levels, Dihydro Coumarin can introduce soft aromatic sweetness to patchouli, oakmoss, citrus and woody compositions.

Its smooth character helps balance dry, mossy and herbal fragrance effects.

Dihydro Coumarin vs Regular Coumarin

Although chemically related, these materials create different effects in fragrance compositions.

Dihydro Coumarin

Smooth, creamy tonka character

Noticeable coconut and lactonic nuances

Soft vanilla sweetness

Gentle almond and tobacco undertones

Warm hay-like character

Particularly useful for creamy gourmands, tobacco and sandalwood accords

Coumarin

• More recognizable sweet-hay character

• Distinctive tonka bean impression

• Powdery almond and vanilla-like facets

• Traditional aromatic fougère character

• Useful in lavender, oakmoss, tobacco and oriental-inspired fragrances

Dihydro Coumarin can complement Coumarin in a fragrance formula, but the two are not direct one-for-one substitutes.

Both materials must be assessed against their respective safety requirements when used in finished fragrance products.

Working With Dihydro Coumarin 10%

Dihydro Coumarin has a relatively low melting point and may partially solidify or crystallize when ambient temperatures fall.

A prepared working solution makes it easier to handle and incorporate into small fragrance batches.

Elysian Perfumes supplies Dihydro Coumarin as a 10% solution in DPG for convenient and controlled formulation.

Example formulation by weight:

• Dihydro Coumarin (100% neat): 10 g

• Di propylene Glycol (100% neat): 90 g

• Total: 100 g of 10% w/w working solution

Gentle controlled warming and thorough mixing may be used where necessary during preparation.

Allow the solution to return to ambient temperature and verify clarity and stability before bottling.

The 10% working solution contains one-tenth the active Dihydro Coumarin of an equal weight of undiluted material.

When incorporating it into fragrance formulas, evaluate its effect gradually to achieve the desired balance between creamy sweetness, coumarinic warmth and other fragrance elements.

Important Formulation & Safety Considerations

Dihydro Coumarin is subject to an IFRA Standard restricting its concentration in finished fragrance products.

Under IFRA Amendment 51, the maximum concentration for Category 4 fine fragrances is 0.21% Dihydro Coumarin in the finished product.

This limit applies to the active aroma chemical, not simply the weight of the prepared DPG solution.

For example, a fragrance containing 1 g of a 10% Dihydro Coumarin solution contains 0.1 g of active Dihydro Coumarin.

Other finished-product categories have different limits.

Always consult the applicable current IFRA Standard, the product Safety Data Sheet and relevant regulatory requirements when formulating commercial products.

The 10% working solution is intended for fragrance formulation and must not be applied directly to the skin.

Storage Information

Store tightly sealed in a cool, dry and well-ventilated location, protected from direct sunlight and excessive heat.

Keep the container securely closed to prevent contamination and unnecessary exposure to air.

Because the undiluted material has a melting point near normal room temperature, changes in appearance may occur with temperature fluctuations.

Monitor the prepared solution for clarity, separation or crystallization during storage.

Use clean measuring equipment and avoid introducing moisture or contaminants.

Perfume Grade Quality

Elysian Perfumes supplies Dihydro Coumarin as a prepared 10% working solution designed for convenient and controlled fragrance development.

Its beautiful combination of tonka bean, creamy coconut, soft vanilla, warm hay and subtle tobacco nuances makes it a valuable ingredient for sophisticated gourmand, fougère, woody amber and modern fragrance compositions.

Particularly suitable for professional perfumers, independent fragrance creators and fragrance developers seeking smooth, warm and long-lasting coumarinic effects.

For fragrance formulation use only. This material is not a food flavouring, finished perfume or product intended for direct skin application. Finished formulations must comply with applicable safety and IFRA requirements.
