THE STORY OF BENZYL ALCOHOL
Benzyl Alcohol: The Dual-Function Preservative & Solvent
Benzyl Alcohol is a multi-functional cosmetic ingredient that acts as a preservative, solvent, and fragrance component. Naturally occurring in essential oils like jasmine and ylang-ylang, it is widely used in creams, serums, lotions, haircare, and pharmaceutical topical products
Naturally Present in Essential Oils, Refined for Industry Use
Although Benzyl Alcohol occurs naturally in plant oils, commercial supply is produced through controlled synthesis and purified to achieve pharma & cosmetic-grade quality. TRCkem supplies high-assay benzyl alcohol with low impurity levels, suitable for leave-on and rinse-off formulations.
Preserve. Dissolve. Stabilize.
Roles & advantages in cosmetic formulations:
✅ Acts as a broad-spectrum preservative (often paired with potassium sorbate or salicylic acid)
✅ Works as a solvent for fragrances, actives & essential oils
✅ Enhances spreadability and reduces viscosity in emulsions
✅ Approved for natural and organic formulations (ECOCERT, COSMOS accepted)
✅ Mild aroma makes it suitable for skincare, baby care & haircare
Used in lotions, serums, cleansers, shampoos, sunscreens, and topical pharma creams.
Globally Approved, But Concentration-Controlled
Typical usage level: 0.5–1.0% as preservative (up to 5% as solvent).
Maximum allowed in leave-on cosmetics: 1% (EU/US).
Readily biodegradable and accepted in natural & clean-label formulas.
May cause irritation at high concentration — must be used within global cosmetic limits.
Fully listed in INCI, EU Annex V, FDA, and Japanese standards as an approved cosmetic preservative.

7. Can Benzyl Alcohol be combined with other preservatives?
Yes, it is often used with:
Phenoxyethanol (for enhanced microbial protection)
Sodium Benzoate (to increase preservative efficacy)
Ethylhexylglycerin (as a preservative booster)
8. Does Benzyl Alcohol cause any side effects?
Benzyl Alcohol is safe at recommended levels, but potential side effects include:
Mild skin irritation in high concentrations.
Eye irritation if applied near the eyes.
Allergic reactions (rare, but possible for sensitive individuals).
9. What is the recommended concentration of Benzyl Alcohol in personal care formulations?
Up to 1% in leave-on products.
Up to 5% in rinse-off products.
Up to 10% in preservative systems.
10. Is Benzyl Alcohol natural or synthetic?
