Overview
Ingredient Profile
Role of Natamycin
Active Cosmetic Mechanisms
ANTIMICROBIAL
Germ FighterInhibits the growth of bacteria, fungi, and other microorganisms
SCIENTIFIC ANALYSIS
// Evidence: Antimicrobial agents possess bactericidal, bacteriostatic, fungicidal, or fungistatic properties through disrupting cell membrane integrity, inhibiting protein synthesis, interfering with metabolic pathways, or damaging DNA/RNA. Common antimicrobials include quaternary ammonium compounds, alcohols, chlorhexidine, triclosan, and essential oils. Efficacy depends on concentration, pH, contact time, and microbial load.
PRESERVATIVE
Product ProtectorPrevents microbial contamination and extends shelf life
SCIENTIFIC ANALYSIS
// Evidence: Preservatives inhibit microbial growth through various mechanisms: disrupting cell membranes (phenoxyethanol, parabens), releasing formaldehyde (DMDM hydantoin), chelating essential nutrients, or creating unfavorable pH. Broad-spectrum preservatives target bacteria, yeast, and mold. Efficacy depends on concentration, pH, formulation type, and microbial challenge. Must pass preservative efficacy testing (PET/challenge testing) meeting USP, EP, or JP standards.
