What is citronellol and where to find it

Citronellol is a natural substance with a delicate, fresh scent reminiscent of citronella. 🌿It occurs naturally in plants such as lemongrass, rose, geranium, eucalyptus and lavender.

It is obtained through gentle steam distillation from essential oils and is among the popular ingredients in natural cosmetics and aromatherapy.

Its pleasant scent contributes to refreshing spaces and is part of products used for a feeling of cleanliness and freshness. Thanks to its plant origin, citronellol is often perceived as a gentle alternative to synthetic fragrances and repellent ingredients.

Citronellol as natural protection against insects

Citronellol belongs among natural substances that are traditionally used in products designed for outdoor activities.
Its fresh citrus scent helps create an environment that insects typically don't favor, and thanks to this, it can contribute to greater comfort during summer activities.

🌿 Benefits of citronellol – natural ingredient known for its fresh scent, often used in products for outdoor activities.

How citronellol differs from chemical repellents

On the market, you'll commonly find products containing chemical substances such as DEET, icaridin, or permethrin. While these work effectively, they can:

• burden the skin
• have a strong chemical odour
• or be unsuitable for children and pregnant women

Citronellol, on the other hand, represents a natural alternative with a gentler and fresher scent. Thanks to its plant origin, it tends to be gentler on the skin and the environment and is suitable for everyday use – especially for people with sensitive skin.

It's most commonly used for:

• air freshening and creating a clean atmosphere
• feeling of relaxation during stress or tension
• concentration support during work or study
• interior scenting and elimination of unwanted odors

Aroma diffusers, lamps or natural air fresheners containing citronellol help create a harmonious home environment with a light citrus scent.

Citronellol has found its place not only in cosmetics, but also in everyday household use. You can use it in making scented candles, in air fresheners or diffusers or even natural cleaning products.

💡 Household inspiration: Add a few drops of essential oil with citronellol to a homemade candle or aroma lamp and create a pleasantly scented environment for evening relaxation.

What to Watch Out For: Safety and Sensitivity

Even though citronellol is a natural ingredient, there are a few rules for safe use:

• Sensitivity test – Before first use on skin, perform a tolerance test – apply a small amount of diluted oil to the inner forearm and wait 24 hours.
• Avoid sun exposure after application – Citronellol may increase skin sensitivity to UV radiation. Therefore, avoid direct sunlight for at least a few hours after use.
• Caution with children and pregnant women – Essential oils (including those containing citronellol) should be consulted with a doctor before use – especially for pregnant women, nursing mothers and small children.
• Allergic reactions – More sensitive individuals may experience irritation. If redness or itching occurs, immediately rinse the area with water and discontinue use.
