Neryl Acetate (FG & Technical Grades): The Soft Floral–Citrus Bridge for Flavors & Fragrances
Executive Summary
Neryl Acetate is a delicate ester valued for its soft, rosy–floral aroma combined with light citrusy freshness. It acts as a smooth transition between top and heart notes in fragrances and adds subtle elegance to citrus, floral, and fruit-forward flavor compositions. This whitepaper provides a technical overview, covering chemistry, sensory profile, stability, applications, and regulatory guidance—independent of any specific brand.
What Is Neryl Acetate? (Chemistry & Structure)
Neryl Acetate is the acetate ester of Nerol, chemically named cis-3,7-dimethyl-2,6-octadien-1-yl acetate. It is a monoterpenoid ester that naturally occurs in essential oils like neroli, citronella, and lemongrass. Compared with Nerol, Neryl Acetate is softer, sweeter, and less green, providing a smoother floral–citrus experience.
Key Identifiers & Compliance Snapshot
Parameter | Neryl Acetate |
Name (IUPAC / common) | Neryl Acetate (cis-3,7-dimethyl-2,6-octadien-1-yl acetate) |
CAS Number | 141-12-8 |
FEMA Number | 2773 |
EC / EINECS | 205-459-2 |
INCI / Flavor Use | Parfum; Flavouring Agent |
Grade Availability | Grade selection: Confirm the supplied grade and intended use |
Note: Verify the supplied grade and purity using its specification and COA. Confirm applicable REACH obligations, current IFRA restriction information for fragrance use, and food-use requirements for the intended application and market.
Sensory Profile & Odor Threshold
Signature: soft rose, light citrus, gentle fruity nuance.
Odor threshold: low to moderate; effective at small concentrations.
In flavors, adds subtle sweetness and smooth citrus lift.
In fragrances, enhances floral accords and acts as a bridging note between top and heart layers.
Physico-Chemical Properties (Formulator Notes)
Appearance: colorless to pale yellow liquid
Boiling Point: approximately ≈235–245 °C at 1 atm (or ≈134 °C at 25 mmHg under reduced pressure) — cite reduced-pressure value if vacuum distillation is referenced.
Density (ρ₂₀): ≈ 0.905–0.914 g/cm³ at 20 °C
Refractive Index (n₂₀/D): ≈ 1.458–1.465
Solubility: insoluble in water; soluble in alcohols, oils, esters, perfumery carriers
Stability: sensitive to oxidation and light; store airtight, preferably under inert gas
Grades, Quality & Documentation
Confirm grade availability and specifications with the supplier. For food use, request evidence of suitability for the intended application and market, including any claimed FCC conformance. Documents to request:
COA (Certificate of Analysis)
SDS (Safety Data Sheet)
TDS (Technical Data Sheet)
Information on applicable IFRA Standards and raw-material restrictions (for fragrance use)
Flavor/Food Compliance Statement
Current allergen declaration; GMO/Non-GMO, Vegan, Halal or Kosher documentation where relevant and available
Applications & Typical Use Levels
Flavors
Used in citrus, tropical, and floral–fruit flavorings.
Supports subtle rosy, lemon, and exotic fruit notes.
Typical use levels: 1–10 ppm in finished products; adjust per local regulations.
Fragrances & Consumer Products
Common in perfumes, personal care, air care, and household products.
Lifts floral hearts and adds soft citrus brightness.
Typical dosage: trace to 2% depending on formula.
Formulation Strategy & Pairings
Pairs well with: Nerol, geraniol, citronellol; citrus oils (lemon, orange, mandarin); floral notes (rose, orange blossom, jasmine); green and light musk notes.Role: Bridges top-to-heart floral notes, adds softness to citrus or fruity blends, enhances “dewy” effect.Tips: Start at low ppm (<1%), monitor oxidation in emulsions/high-pH systems, rebalance with green/woody notes if overly sweet.
Stability, Storage & Packaging
Store in sealed, light-protected containers (aluminum or lacquered glass).
Cool, dry, away from direct light and heat.
Recommended: nitrogen blanket for long-term stability.
Shelf life: 12–24 months depending on storage conditions.
Regulatory & Safety Overview
Flavor use: Confirm the supplied grade's permitted use, conditions and specifications for the intended food application and destination market.
Fragrance use: Check the current IFRA Standards and supplier restriction information for the exact material and intended finished-product category.
Allergen status: Request a current supplier allergen declaration and assess finished-product labelling under applicable requirements, including EU Regulation 2023/1545 for cosmetics.
Safety: Use the current SDS for the supplied grade to determine hazard classification, handling precautions and exposure controls.
Safety: Avoid concentrated inhalation; wear gloves; follow SDS.
Analytical & QC (GC-MS, Assay)
Identity: GC-MS confirmation (retention index & spectrum).
Assay: ≥97% GC area purity typical.
Monitoring: ester content, oxidation products, residual solvents.
Purchasing Checklist & FAQs
Checklist:☑ Grade (FG or Technical) verified on COA☑ CAS 141-12-8 / FEMA 2773 / EC 205-459-2 match internal specs☑ Regulatory declarations & SDS received☑ Shelf life & packaging suitable for application☑ Pilot tested in final product
Selected FAQs:
Q: Can Neryl Acetate replace Nerol?A: Not exactly — Neryl Acetate is softer and sweeter; use as a complement.
Q: Does it oxidize easily?A: Moderate sensitivity to air/light; store under inert gas when possible.
