Citrepel75 vs Citriodiol: What’s the Difference and Which Is Better?

When it comes to natural insect repellents, PMD-rich oils are widely recognised as the only effective plant based (Natural) solutions available. Two names often come up in this space: Citrepel75 and Citriodiol. While they are frequently grouped together, assuming they are the same would be a mistake.

Citrepel75 is derived from Java Citronella and Citriodiol is derived from Eucalyptus Citriodora.  Both contain PMD (para-menthane-3,8-diol) which is what repels insects, but this is where the similarities largely end. In this article, we break down the key differences between Citrepel75 and Citriodiol, and explain why Citrepel75 stands out as the more refined, effective, and skin-friendly option.

What Is Citriodiol?

Citriodiol is an oil containing PMD, traditionally used in insect repellent formulations. While effective, it is a less refined material, meaning it contains a wider range of  impurities from the production process.

Limitations of Citriodiol

• Lower PMD concentration compared to Citrepel75 = Less effective 

• Presence of residual compounds that may contribute to skin irritation in sensitive users

• A distinctive and often criticised odour, commonly described as a “dirty citrus” smell

• Oily and greasy skin feel, which can be unpleasant for consumers

• Often requires alcohol-based formulations to stabilise and disperse the oil

Alcohol, while functional in formulations, can be drying to the skin, particularly with repeated application or in warmer climates.

What Is Citrepel75?

Citrepel75 is a highly refined PMD-rich oil, developed to overcome the drawbacks associated with older PMD oils like Citriodiol. Through advanced purification processes, Citrepel75 delivers a significantly higher PMD content, typically around 75%, with far fewer impurities.

Key Benefits of Citrepel75

1. Higher PMD Content = Better Efficacy

With its elevated PMD concentration, Citrepel75 offers stronger and longer-lasting insect repellency. More active ingredient means improved performance against mosquitoes and other biting insects.

2. Greater Purity for Improved Skin Comfort

The refinement process removes many of the unwanted by-products found in Citriodiol. This results in:

• Reduced risk of skin irritation

• Better suitability for sensitive skin

• A cleaner, more consistent ingredient profile

3. Superior Odour Profile

Unlike Citriodiol’s characteristic “dirty citrus” smell, Citrepel75 has a much cleaner and more neutral fresh lemon scent which quickly dissipates after application, making it far more appealing for consumer facing products such as lotions, sprays, and aerosols.

4. Non-Greasy, Premium Skin Feel

Citrepel75 does not leave the heavy, oily residue commonly associated with Citriodiol. When formulated correctly, it delivers a light, smooth, and nourishing skin feel that enhances user experience.

5. Alcohol-Free Formulation Options

One of the standout advantages of Citrepel75 is its ability to be used in alcohol-free emulsions. This allows formulators to create products that:

• Are gentler on the skin

• Avoid dryness and irritation

• Feel moisturising rather than stripping

Why Choose Citrepel75 for Modern Insect Repellent Products?

Today’s consumers expect more than just effectiveness. They want comfort, safety, and a premium sensory experience. Citrepel75 meets these expectations by combining high performance insect repellency with excellent skin compatibility and formulation flexibility.

This is why THEYE® always uses Citrepel75 in all of its formulations. It is greatly more expensive but we feel it is worth it and what customers demand to ensure a high quality  finished product.

Final Thoughts

While Citriodiol and Citrepel75 may both be PMD-rich oils, they are not equal ingredients. Citrepel75’s higher purity, increased PMD content, and formulation advantages make it a next generation solution for insect repellent products. Citrepel75 is clearly the superior choice.
