Chemical Properties and Regulatory Recognition
Acetophenone (CAS 98-86-2) is a colorless to pale yellow liquid under ambient conditions. The substance’s boiling point is approximately 202 °C and its density is around 1.03 g/mL at 15 °C. The compound has a floral or orange-blossom like odor and a mildly bitter aromatic taste.
Regulatory frameworks in major jurisdictions allow acetophenone use in fragrances, flavorings, food, and personal-care products under specified limits and good-manufacturing-practice guidelines.
The United States Environmental Protection Agency (EPA) lists acetophenone as a fragrance ingredient in soaps, detergents, lotions, creams, and perfumes. The same regulatory classification recognizes acetophenone as a synthetic flavoring substance permitted for direct addition to food under the U.S. Food and Drug Administration (FDA) regulations (source: www.epa.gov).
Safety data indicates that exposure to acetophenone vapors at high concentrations can cause skin or eye irritation and transient corneal injury. The EPA classifies acetophenone as “Group D, not classifiable as to human carcinogenicity,” implying insufficient evidence for classification as a carcinogen. Consumers and manufacturers adhere to regulated concentration limits to ensure safe use in flavor and fragrance products.
Functional Role in Fragrance Formulation
Acetophenone’s olfactory profile contributes a sweet, slightly floral tone often described as jasmine- or orange-blossom-like, with subtle balsamic and almond-like nuances depending on concentration. Its stability under normal storage conditions and compatibility with many solvent and carrier systems make acetophenone a reliable building block for fine fragrances. (source: www.chemicalbook.com)
Perfume and fragrance formulators frequently deploy acetophenone in floral, oriental or soft-powdery accords to impart warmth, depth, and rosy floral character. The ketone acts sometimes as a fixative or enhancer, helping to stabilize scent profiles and extending the perceived longevity of lighter top-notes in complex blends.
Published ingredient-data sheets from recognized suppliers identify acetophenone under the standard industry nomenclature (e.g., INCI name, FEMA designation) for use in fragrances, cosmetics, and personal-care products.
The versatility of acetophenone allows its use across a wide variety of products including fine perfumes, body lotions, soaps, detergents, creams, and air-care products. Its floral scent profile complements other aroma chemicals such as ionones, heliotropin, benzyl acetate, and esters to craft nuanced fragrances that appeal across global markets.
Role in Flavor Formulations
Acetophenone functions as a flavoring agent in food and beverage products. The U.S. FDA permits its use as a synthetic flavoring substance under regulations for direct food additives.
Food-chemistry sources note its application in nonalcoholic beverages, baked goods, candies, gelatins, puddings, chewing gum, and similar consumables where a mild, aromatic, somewhat almond- or cherry-like note is desirable.
Such applications are effective at low concentrations, which balances sensory impact with regulatory compliance and safety. The relative chemical stability of acetophenone helps preserve desired flavor profiles through processing, storage and distribution.
Its aroma contribution can enhance sweet or floral-fruity flavor notes, contributing to a more refined organoleptic profile in confectioneries, beverages, and bakery goods.
Benefits of Acetophenone Use for Formulators
- Versatility across Media and Product Types
The chemical properties of acetophenone, solubility in organic solvents, moderate volatility, and stable odor profile allow it to be used in diverse media: alcohol-based perfumes, oil-based lotions, water-emulsion creams, detergents, food emulsions, and flavor bases.
