What is Benzyl Alcohol 99.9%?
Benzyl Alcohol (C6H5CH2OH) is an aromatic alcohol that appears as a clear, colourless liquid with a mild pleasant aroma. It is naturally found in some fruits and teas and is often derived from benzyl chloride or toluene in industrial processes.
- Molecular formula: C7H8O
- Molar mass: 108.14 g/mol
- Boiling point: ~205.3°C
- Density: 1.045 g/cm3
- Solubility: Soluble in alcohol, ether, and slightly soluble in water
The designation "99.9%" refers to the high purity of the product, making it ideal for cosmetic and pharmaceutical applications where impurities can compromise stability, efficacy, and safety.
Benzyl Alcohol as a Cosmetic Solvent
Why Use Benzyl Alcohol in Lotions & Creams?
Solvents play a critical role in cosmetics by helping to dissolve active ingredients, reduce viscosity, and improve spreadability. Benzyl Alcohol is particularly effective because it is:
- Non-greasy and evaporates slowly
- Compatible with emulsifiers and oils
- Stable at a wide pH range
Practical Usage Example:
To create a moisturising body lotion:
- Phase A (Oil phase): 5g shea butter, 3g almond oil, 0.5g emulsifier
- Phase B (Water phase): 80ml distilled water
- Additive phase: 0.8g Benzyl Alcohol (0.8%) as a solvent and preservative
Mix the oil and water phases separately, heat to 70°C, combine and blend. Once cooled to below 40°C, add Benzyl Alcohol to the emulsion.
This allows active botanicals and essential oils to remain uniformly distributed in the formula.
Benzyl Alcohol as a Preservative in Skincare & Haircare
Antimicrobial Benefits
Benzyl Alcohol exhibits bacteriostatic and fungistatic properties. It is often used alongside other preservatives (like dehydroacetic acid) in broad-spectrum systems. It is particularly effective against:
- Gram-positive and Gram-negative bacteria
- Moulds and yeasts
Safe Usage Concentration
- In leave-on and rinse-off products: 0.5% to 1.0%
- Maximum allowed in cosmetics (EU regulations): 1.0%
Example Formulation (Leave-on Facial Cream):
- Water: 60%
- Oils and emollients: 30%
- Emulsifier: 5%
- Active ingredients (niacinamide, panthenol): 4%
- Benzyl Alcohol 99.9%: 1g per 100g batch

- Enhances solubility of essential oils in alcohol-based perfumes
Practical Example: DIY Eau de Toilette
- Ethanol (95%): 75ml
- Distilled water: 20ml
- Fragrance oil blend: 4ml
- Benzyl Alcohol 99.9%: 1ml (1%) as fragrance stabilizer
Mix all ingredients and allow to macerate for 1-2 weeks.
