Applications of 557-48-2
| Industry | Application | Processing |
|---|---|---|
| Fragrance & Flavor | Used in formulating fresh, green-leaf and fruity fragrances—such as citrus, cucumber, watermelon, and leafy green—to impart natural, crisp top notes | Applied as a key fragrance ingredient in fragrance formulations; typically added at 0.1–5 ppm concentration to household or food-grade fragrances (e.g., shower gels, shampoos) or food flavors, directly dissolved in solvents such as ethanol or diethyl phthalate prior to blending with other aroma chemicals |
| Food Industry | Used as a food flavoring agent to enhance fruit flavors—particularly watermelon and cucumber—and improve overall aromatic complexity | Used as a synthetic flavoring substance in beverages, confectionery, and ice cream in accordance with GB 2760–2024 “National Food Safety Standard – Usage Standard for Food Additives”; maximum permitted levels are controlled within 0.1–1.0 mg/kg based on FAO/WHO JECFA evaluations, and the compound is uniformly incorporated into the formulation after dilution in an appropriate solvent |
| Household & Personal Care Products | Imparts a natural green-leaf odor to detergents, fabric softeners, and air fresheners, enhancing product sensory performance | Blended with surfactants and solvents at ambient temperature; no heating or catalysis required. Due to thermal sensitivity, processing temperature must be maintained at ≤40 °C to prevent cis-trans isomerization and aldehyde oxidation |
