Applications
Cosmetics and Personal Care
- Preservative in Creams and Lotions: Added at 0.3-1.0% to inhibit microbial contamination, ensuring stability in oil-in-water emulsions for up to 24 months.
- Solvent in Perfumes and Deodorants: Dissolves essential oils and fragrances at 5-20%, providing clear, stable formulations without separation.
Pharmaceuticals and Healthcare
- Injection Solvent: Used as a co-solvent in parenteral drugs at 1-2% to enhance solubility of poorly water-soluble APIs like diazepam.
- Ointment Base: 5-10% in topical preparations for anti-itch and anesthetic effects, with rapid absorption and low sensitization risk.
Industrial Uses
- Paint and Coating Thinner: 2-5% in lacquers to adjust viscosity and improve flow without affecting dry time.
- Ink and Dye Carrier: Solvent for pigments in printing inks, ensuring even application and color vibrancy.

Frequently Asked Questions (FAQs)
What is Benzyl Alcohol?
Benzyl Alcohol is an aromatic alcohol with the formula C₆H₅CH₂OH and CAS 100-51-6, used as a preservative and solvent. It’s a colorless liquid with mild odor, effective for microbial control and solubility enhancement in cosmetics and pharma.
How is Benzyl Alcohol used as a preservative?
Incorporate at 0.5-1.0% during the aqueous phase of emulsions; it penetrates cell walls to disrupt metabolism, effective against Pseudomonas and Candida in pH 3-8 ranges.
Is Benzyl Alcohol safe for skin applications?
Yes, it’s CIR-approved up to 5% in leave-on products and 10% in rinse-off, with low irritation (0.1% in 48-hour patch tests), though rare allergies may occur—perform stability challenges.
What is the shelf life of Benzyl Alcohol?
In sealed, light-protected containers at <25°C, it retains >99% purity for 3-5 years, resistant to oxidation but monitor for peroxide formation in air-exposed samples.
Can Benzyl Alcohol be combined with other preservatives?
It synergizes with parabens or phenoxyethanol at 0.5:0.5 ratios for broader spectrum but avoid strong oxidants; it’s stable in blends with glycerin and propylene glycol.
Does Benzyl Alcohol affect product odor?
Its faint floral scent is negligible at <1%, blending seamlessly with fragrances; high-purity grades like ours are virtually odorless for neutral formulations.
What packaging options are available for Benzyl Alcohol?
We supply 190kg galvanized drums, 1000kg composite IBCs, and 20MT isotanks, all lined for chemical resistance and compliant with UN 1993 for global transport.
For preservation challenges, solubility data, or custom blends, our formulation team provides expert solutions.
