Citronellol (CAS 106-22-9): The Essential Monoterpene Alcohol in Fragrance & Personal Care Formulation

If you are formulating anything from a luxury fine fragrance to a soothing daily body lotion, you already know the power of a perfect floral note. At the very heart of that fresh, dewy rose profile is Citronellol CAS 106-22-9. Far more than just a simple scent, this versatile monoterpene alcohol is a foundational building block for modern cosmetics and perfumery.

At Mikemchem, we understand that R&D chemists and procurement managers don’t just need raw materials—you need supply chain security, batch-to-batch consistency, and ingredients that perform flawlessly under pressure. As a leading global supplier, we are here to help you navigate the complexities of sourcing and ensure your next formulation is a resounding success.

Here is everything you need to know about working with this indispensable aroma chemical.

Aroma Profile & Chemical Properties of Citronellol CAS 106-22-9

Before you can build a great product, you have to understand your materials. For a formulation chemist, Citronellol CAS 106-22-9 (chemically known as 3,7-Dimethyloct-6-en-1-ol) is a hardworking, highly functional molecule prized for its incredible stability.
The Aroma Profile:
It delivers a universally loved fresh, clean rose scent with very subtle green, waxy, and citrusy undertones. As a classic middle note (or heart note), it gives fragrances their core blooming character without evaporating too quickly.

Beyond its great scent, its chemical structure gives it moderate fixative properties, helping to anchor highly volatile top notes so your product smells great long after the first application.

Core Applications of Citronellol CAS 106-22-9 in Fragrance and Personal Care

Thanks to its versatility and stability, Citronellol CAS 106-22-9 is a heavy hitter across multiple product categories:

• Fine Fragrances: It is the secret weapon for creating the “magic rose blend.” When formulators combine it with Geraniol and Phenethyl Alcohol (PEA), it creates a deeply authentic, classic rose core used in high-end perfumes globally.
• Cosmetics & Skincare: Because it remains crystal clear and chemically stable in neutral and mildly acidic environments, it is widely used to gently perfume face creams, body lotions, and shampoos without causing discoloration.
• Heavy-Duty & Functional Products: This is where it really shows off. While many fragrance molecules degrade or mutate in high-pH (alkaline) environments, Citronellol CAS 106-22-9 holds its ground. This makes it a go-to choice for traditional bar soaps, heavy-duty laundry detergents, and household cleaners.
• Outdoor Products: Because its structure is similar to active compounds in citronella oil, it naturally offers mild insect-repellent properties, making it a brilliant addition to summer lotions and outdoor body sprays.

Natural vs. Synthetic Citronellol CAS 106-22-9: What Formulators Need to Know

With the industry shifting toward “Clean Beauty,” the debate between natural botanical extracts and synthetic aroma chemicals is louder than ever.

In nature, Citronellol is found abundantly in rose, geranium, and lemongrass essential oils. However, relying purely on botanical extraction for commercial production is a procurement nightmare—it brings extreme price volatility, crop-yield risks, and a massive ecological footprint.

This is why high-purity, nature-identical Citronellol CAS 106-22-9 is the industry standard. It gives you the exact same molecule and authentic scent profile as the natural extract, but with absolute consistency. For procurement teams and R&D, synthetic sourcing means cost-effective scalability, a reliable supply chain, and zero worries about a bad harvest ruining your fragrance brief.

Safety and Regulatory Compliance for Citronellol CAS 106-22-9

Great formulations require strict attention to safety. While Citronellol CAS 106-22-9 is incredibly safe for general cosmetic use, it does require careful handling regarding industry regulations.

• Allergen Declaration: It is listed as one of the standard fragrance allergens. Under EU Cosmetics Regulations and strict IFRA (International Fragrance Association) guidelines, its presence must be declared on product ingredient labels if it exceeds certain thresholds in leave-on or rinse-off products.
• Oxidation Control: The biggest safety risk with low-grade Citronellol is oxidation. If the raw material is poorly distilled or stored, it forms peroxides over time, which can cause skin sensitization. This is why sourcing ultra-high purity grades with low peroxide values is non-negotiable for skin-safe formulations.
