Evicide® rose eco (INCI: Phenethyl Alcohol) is a 100% natural, aromatic alcohol. Known chemically as 2-phenylethanol, this clear, colorless liquid is a nature-identical multifunctional ingredient. It is a strategic choice for formulators who need to combine fragrance masking with a robust antimicrobial boost. Because its mechanism is physical rather than chemical, it offers a major advantage: it remains fully effective across the entire cosmetic pH range.
Key Benefits and Performance
-
pH-Independent Antimicrobial Activity: it remains active at neutral or even alkaline pH, providing critical flexibility for high-pH cleansers.
-
Targeted “Hurdle” Synergy: It is rated “very good” against Gram-negative bacteria and moulds. This makes it the perfect partner for other natural preservatives that may be strong against Gram-positive bacteria but weaker against these specific contaminants.
-
Membrane-Disrupting Mechanism: As an amphiphilic molecule, it works by disrupting microbial cell membranes and inhibiting intracellular enzymes. This physical mode of action makes it difficult for microorganisms to develop resistance.
-
Natural Masking Agent: It possesses a delicate, rose-like aroma. It is exceptionally useful for masking the undesirable “chemical” odors of certain raw materials, often allowing for “fragrance-free” labeling (subject to local regulations).
-
Heat Stable & Water Soluble: It is easy to handle in a manufacturing environment. It is fully water-soluble and can withstand the high temperatures required for hot-process emulsions.
Formulation Guidelines
-
Applications: Ideal for micellar waters, facial toners, high-pH liquid soaps, and natural emulsions.
