Phenethylalcohol nat. (INCI: Phenethyl Alcohol) is a 100% naturally derived aromatic alcohol produced through the fermentation of sugarcane. As a high-purity, renewable alternative to petrochemically sourced phenethyl alcohol, it offers identical functional performance with a superior ecological footprint. This clear liquid is a true multifunctional powerhouse, combining robust antimicrobial protection with a delicate, rose-like fragrance that naturally masks base odors in complex formulations.
Key Benefits and Performance
-
Universal pH Independence: One of its most significant technical advantages is that its efficacy is entirely independent of pH
-
Targeted Antimicrobial Profile: Especially strong against Gram-negative bacteria and moulds.
-
Synergy Potential: Shows good activity against Gram-positive bacteria and yeasts, which can be further amplified when paired with co-actives like Cosphaderm® Pentiol natural.
-
-
Natural Fragrance & Masking: It possesses a mild, pleasant rose-like scent. This allows formulators to use it as a functional “fragrance-masking” agent to cover the undesirable chemical odors of other raw materials while simultaneously preserving the product.
- Versatility: Effective in both aqueous (water-based) and powder systems, providing a rare preservation solution for anhydrous or dry formulations.
- The “Hurdle” Strategy: For full broad-spectrum protection in high-risk water-based formulas, it is often combined with a booster such as Propanediol or Caprylyl Glycol.
