Product Overview & Core Technical Identity

SUNWAY supplies high-purity Methyl Ionone (methylionone, mixture of methyl-alpha-, methyl-beta- and methyl-gamma-ionone isomers), a classic cyclic ketone fragrance raw material identified by CAS 1335-46-2, EC 215-635-0 and FEMA No. 2711, supplied under IFRA-compliant and RIFM fragrance safety assessment scope and EU Regulation 1223/2009 cosmetic ingredient requirements. This pale yellow oily liquid carries a violet-like, woody and orris fragrance with a soft powdery undertone; it is a standard middle-note building block for violet, osmanthus, acacia, mimosa, lily, chypre, amber and oriental fragrance complexes. Controlled fractional distillation and isomer composition tuning guarantee stable GC assay and consistent violet-woody odor profile batch to batch. Every batch completes full GC assay (total ionones and alpha-methyl ionone), density, refractive-index and safety-indicator testing, with 12-month sealed sample retention for full quality traceability. Mixed consolidated shipment with other SUNWAY fragrance ingredients is supported to lower overall procurement and logistics costs.

Physiological Functions & Industry Application Logic

1.Violet & Orris Floral Accord Builder Methyl Ionone reproduces the soft violet and orris floral heart expected in floral perfumes; together with natural orris absolute, it forms the signature violet note in women's fragrances and fresh body-care aromas.

2.Woody-Powdery Modulator for Floral Bouquets Its woody, powdery and slightly fatty undertone rounds fresh rose, jasmine, peony and freesia accords, softening sharp floral top notes and building a smooth, well-balanced middle fragrance body.

3.Fine Perfume Middle-Note Foundation As a stable cyclic ketone it acts as the middle-note carrier of chypre, oriental, amber and woody complexes, blending harmoniously with citrus top notes, hedione, oakmoss, musk and vanilla base notes to extend fragrance persistence.

4.Soap & Household Fragrance Stabilizer Methyl Ionone withstands alkaline saponification conditions, retaining a stable violet-woody scent in toilet soap, laundry detergent and household cleaning products, and masking unpleasant base-material odors of soap noodles and surfactant systems.

5.Oriental, Chypre & Amber Blend Component It supplies a floral-woody bridge between fresh citrus top notes and warm vanilla-amber base notes, making it a standard accord component for oriental perfume, men's fougere and scented candle fragrance compounds.

Key Property Reminder: Methyl Ionone is an easily oxidized, light-sensitive oily liquid. Long exposure to air, light and heat causes color darkening, odor deterioration and impurity growth; it must be stored under nitrogen protection, sealed, dark and away from oxidizing substances, and its finished fragrance dosage shall comply with current IFRA concentration limits.

Sunway Packaging, Supply & Delivery Capacity

Standard Packaging Specifications

Trial Small Batch: 5kg sealed light-blocking aluminum bottle with nitrogen headspace, leak-proof and oxidation-resistant for fragrance-house formula R&D and small-batch trial compounding.

Industrial Bulk Shipment: 25kg sealed food-grade plastic drum with inner liner, stable for long-term warehouse storage and ocean transit of soap, detergent and cosmetic fragrance programs.

Custom Service: Custom filling weight, nitrogen-flushed sealing and private-label printing available for long-term cooperative fragrance manufacturers and perfume compounders.

Stable Spot Inventory & Supply Capacity

SUNWAY maintains year-round sealed spot stock of Methyl Ionone without seasonal out-of-stock risks. Long-term strategic cooperation with certified fractional distillation manufacturers, together with independent dark dry storage zones, ensures stable batch-to-batch GC assay, isomer ratio and violet-woody odor profile for mass procurement demand of fragrance houses, cosmetic factories and detergent manufacturers.

Mixed Consolidated Shipment Support

Methyl Ionone can be consolidated with other SUNWAY fragrance ingredients into one container on separated pallets to prevent cross-odor contamination, eliminating separate delivery fees and cutting overall procurement and warehouse management costs.

Storage, Handling & Shelf Life Guidance

Standard Storage Environment

Store unopened original packaging in a tightly closed, cool and dark warehouse at 10-25 C, under nitrogen protection, with relative humidity Max 60%. Keep strictly away from direct sunlight, heat sources, air exposure and strong oxidizing chemicals. Prevent oxidation that causes darkening, acid-value rise and odor deterioration.

Post-Opening Handling Tips

Reseal the bottle or drum tightly immediately after each sampling, top up with nitrogen when feasible, and finish consumption within 30 days to prevent oxidation, color darkening and odor weakening. Transfer residual liquid into small-volume sealed light-blocking containers for long-term preservation.

Special Operation Reminder

All sampling and batching operations shall be carried out in a dry, ventilated area away from open flame; avoid prolonged contact with air. Do not co-store with strong oxidizers, and avoid repeated drastic temperature fluctuations that promote condensation inside the package.

Valid Shelf Life

24 months under intact sealed nitrogen-protected dark storage; GC assay, physical indicators and odor are fully guaranteed within the expiry date.
