Cinnamaldehyde: Warm Cinnamon Aroma For Candles And Personal Care

The cozy fragrance of cinnamon — known as Dalchini in India — instantly reminds us of warmth, comfort, and festive feelings.It is a naturally occurring organic compound widely used in candles, perfumes, flavours, and personal care formulations.

Cinnamaldehyde belongs to the aldehyde family of aroma chemicals. Its molecular formula is C₉H₈O. It delivers a rich, spicy scent and also provides valuable functional properties in industrial and cosmetic applications.

At Chemicalbull Pvt. Ltd., we supply high-purity Cinnamaldehyde to manufacturers across fragrance, flavour, and personal-care sectors, ensuring reliable quality and global-standard compliance.

What Is Cinnamaldehyde? — The Aroma Chemical Behind Cinnamon’s Signature Scent

Cinnamaldehyde, also known as Cinnamic Aldehyde, occurs naturally in the bark oil of Ceylon and Cassia cinnamon. It gives cinnamon its characteristic spicy flavour and sweet warmth.

Beyond its sensory role, it acts as an intermediate for chemical synthesis and a preservative in certain formulations. Because of these dual functions, it’s a core ingredient in candles, perfumes, and wellness products.

Cinnamaldehyde includes both cis and trans forms, while Trans-Cinnamaldehyde is the pure, natural E-form found in cinnamon oil. The trans form is more stable, smells stronger and lasts longer, and is mainly used in perfumes and high-quality fragrances. It is the main aroma compound in Ceylon and Cassia cinnamon.

Cinnamaldehyde in Candle Manufacturing

Cinnamaldehyde is one of the most popular aroma chemicals for candle fragrance creation. It provides a strong scent throw and stable diffusion even in small concentrations.

Candle Performance Highlights

•          Produces a warm, spicy-sweet aroma ideal for festive or winter themes.
•          Performs consistently in soy, paraffin, and blended waxes.
•          Retains its intensity over time due to chemical stability.
  
  

Suggested Fragrance Blends

Combine Cinnamaldehyde with complementary notes to design unique profiles:

•          Vanilla for a sweet, creamy finish.
•          Clove or Nutmeg for a deep spicy accent.
•          Sandalwood for a smooth woody background.
  
  

Cinnamaldehyde should always be used at controlled temperatures to keep its fragrance strong and safe. At moderate heat, like when used in candles or perfumes, it releases its warm cinnamon aroma — that’s how it gives fragrance to products.

Applications in Personal Care and Cosmetics

In personal-care formulations, Cinnamaldehyde delivers both fragrance and mild antimicrobial activity. Its spicy note enhances body washes, soaps, lotions, and perfumes, giving them a premium sensory appeal.

Formulators generally use it at concentrations of 0.1–0.3% to maintain fragrance balance and minimize skin irritation risks. Proper dilution ensures a pleasant aroma while maintaining compliance with international cosmetic standards. Honey and cinnamaldehyde are often used together for their natural, health-supportive, and aromatic properties.

Typical uses:

·         Perfumed soap bases and shower gels

·         Deodorants for natural freshness

·         Perfume blends with oriental or gourmand themes

Fragrance Profile of Cinnamaldehyde

A Warm and Spicy Scent with Depth

The scent of Cinnamaldehyde is smoky, warm, and a little sweet. Like fresh crushed cinnamon sticks. In perfumery, it is placed between the middle and base notes, bringing complexity and depth to blends.

Blending Potential in Perfumery

When paired with musk, amber, and patchouli, Cinnamaldehyde enhances woody and oriental scents. Smaller dosages can enhance gourmand or floral perfumes with the spicy, tasty brightness.

Longevity and Performance

Its long-lasting scent and strong diffusion make Cinnamaldehyde a staple for premium fragrance formulations. The molecule’s stability also supports fragrance supply chain consistency—a key advantage for manufacturers seeking reliable performance in high-end perfumes.

Cinnamaldehyde in Ceylon and Cassia Cinnamon

Both Ceylon and Cassia cinnamon are primary sources, yet they vary in aroma and composition:

·         Ceylon Cinnamon (Cinnamomum verum): Delicate and sweet fragrance with soft woody undertones.

·         Cassia Cinnamon (Cinnamomum cassia): Higher Cinnamaldehyde concentration, resulting in stronger and more pungent aroma ideal for candles and soaps.

This difference allows manufacturers to choose according to the strength and tone desired in their end products. Now, what is the difference between natural and synthetic Cinnamaldehyde? Let's understand how the two types differ in origin, aroma, and use in fragrance formulations.

Difference Between Natural and Synthetic Cinnamaldehyde

Chemicalbull Pvt. Ltd. offers both types to meet varying technical and commercial needs.

Extraction from Cinnamon Bark

The extraction process involves three main steps to ensure high purity:

1.      Steam Distillation: Cinnamon bark or leaves are distilled to release essential oil.

2.      Solvent Extraction: Concentrates the Cinnamaldehyde fraction from the oil.

3.      Fractional Distillation: Separates impurities and yields a refined aromatic compound.

Both natural and synthetic routes are adopted depending on end-use demands for fragrance or industrial applications.

Cinnamaldehyde as a Natural Insect Repellent

Due to its strong aromatic properties, Cinnamaldehyde works effectively as a natural repellent against mosquitoes and ants. It’s used in DIY insect repellent formulations or blended into household cleaners for a pleasant scent combined with protective functionality.

This makes it a sustainable alternative to harsh synthetic repellents commonly used in consumer products. Citronella oil candle scent also keeps mosquitoes away.
