• 10% dilution in DPG for easy integration in oil or alcohol-based formulas
• Adds diffusive marine freshness and watery coolness to top notes

• Perfect for oil mists, sprays, incense pastes, and roll-ons

Calone (10% in DPG) is a pre-diluted version of the iconic marine-aquatic aroma chemical, known for its ozonic, watery, sea-breeze scent with hints of melon, cucumber, and salty air. This fresh and diffusive material revolutionized perfumery in the 90s and continues to define aqua-inspired, beachy, sporty, and clean unisex compositions.

This 10% dilution in DPG (Dipropylene Glycol) makes Calone easier to use in attars, roll-ons, oil-based perfumes, sprays, and incense blends, where it adds crystal-clear freshness and airy lift.

SCENT DESCRIPTION : Calone opens with a startling blast of ocean spray and melon rind, instantly transporting the senses to a breezy coastal waterfront on a clear summer afternoon. It carries an almost synesthetic quality — simultaneously wet, cool, and faintly sweet — like biting into a chilled slice of watermelon at the edge of the sea. Beneath the marine burst lies a subtle green-ozonic tension that keeps the impression expansive and clean rather than overtly fruity or synthetic. At trace concentrations it reads as a soft aquatic shimmer; at higher doses it becomes an overwhelming marine wave.

Recommended Usage Rates — Calone as Raw Material in Finished Product

EDP (20% fragrance load) : 0.002 to 0.05%
EDT (10% fragrance load) : 0.001 to 0.03%
Body Lotion : 0.001 to 0.02%
Shampoo / Body Wash : 0.001 to 0.02%
Candle : 0.01 to 0.1% of fragrance compound weight
Reed Diffuser : 0.05 to 0.3% of diffuser compound weight
Soap (Tablet) : 0.01 to 0.05% (stability testing recommended)

Note: When using Calone inside a fragrance compound (the perfume oil blend before dilution), typical usage is 0.1 to 1.0% of total compound weight. The finished product rates above are based on Calone as a direct raw material addition.

IFRA 51st Amendment Status

Calone (CAS 28940-11-6) does not appear on the IFRA restricted or prohibited ingredients list under the 51st Amendment at normal recommended usage levels.

⚠️ Always verify against the current IFRA guidelines at ifrafragrance.org before any commercial formulation.
⚠️ Due to extreme potency, always begin at the lowest recommended rate and assess on a smelling strip at 24 hours before scaling.
⚠️ Do not apply undiluted Calone directly to skin. Always handle in dilution of 10% or less for safe working.

Usage Method 1 — Pre-dilution in DPG or Ethanol
Calone in raw crystalline form is too concentrated for direct blend addition in small batches. Prepare a 10% working solution by dissolving Calone in dipropylene glycol or ethanol. This makes dosing precise and controllable, particularly important for small formulations under 100g where even 1 extra drop can result in severe overdosing.

Usage Method 2 — Classic Marine Accord Construction
Use Calone as the nucleus of a complete marine accord at 0.2 to 0.5% within your fragrance compound. Pair with dihydromyrcenol (5 to 8%) and hedione or methyl dihydrojasmonate (3 to 5%) to build the classic 1990s-era aquatic chord. This three-material structure forms the skeleton of countless successful fresh marine fragrances and remains highly relevant for commercial work.

Usage Method 3 — Invisible Transparency Modifier
In contemporary perfumery, Calone at micro-dose (0.03 to 0.1% in compound) functions as an invisible freshener rather than a dominant marine note. Add it to floral, citrus, or woody structures to introduce unexplained coolness and aerial transparency. The composition does not read as marine at this level but gains a dimensionality and lift that is difficult to achieve by other means.

BEST PAIRINGS

Dihydromyrcenol → Amplifies the marine accord and adds laundry-fresh brightness to the ozonic chord
Hedione (MHJ) → Contributes watery jasmine softness that bridges the gap between marine and floral
Ambroxan → Anchors the cool marine opening with skin-warm depth and lasting radiance
Iso E Super → Adds woody diffusion and transparent radiance that complements oceanic shimmer
Violet Leaf Absolute → Deepens the green-watery facet, creating a convincing underwater or riverside accord
Bergamot EO → Citrus brightness that naturalizes the synthetic marine character and lifts the opening
Galaxolide / Habanolide → Clean musks that anchor and extend the Calone-based accord into the dry-down

AVOID
Avoid pairing Calone with heavy phenolic materials such as eugenol-dominant spices or animalic bases — the opposition between clean marine freshness and warm barnyard notes rarely produces coherent results. Also avoid camphoraceous materials including eucalyptus and camphor, which push the accord into a harsh medicinal-aquatic register that is difficult to correct.

💡 To craft a breezy oceanic top note 🌊🍈, use 0.5–2.5% Calone (10% in DPG) in your fresh or aquatic fragrance formulas.

🍉 Blend with fruity notes like watermelon or cucumber for a summer cologne feel.

🌿 Pair with mint, basil, or clean aldehydes to create crisp beachy compositions.

🌸 Add white florals or soft musks for marine-floral perfume styles.

🔄 Shake well before blending into your oil or alcohol base to ensure even diffusion.

⚠️ A little goes a long way—overuse can dominate delicate blends.

Physical State : Crystalline solid, white to off-white powder at room temperature
Skin Safety : Use only in appropriate dilution; avoid prolonged or repeated skin contact at high concentrations; may cause sensitization in susceptible individuals
Eye Contact : Avoid contact; if exposure occurs, flush immediately with clean water for at least 15 minutes and seek medical attention
Ingestion : Not for consumption under any circumstances; keep out of reach of children and pets at all times
Ventilation : Work in a well-ventilated area; the extremely low odor threshold means trace airborne quantities create significant olfactory exposure even without direct contact
Storage : Store in a cool, dry location away from direct sunlight, heat, and humidity; keep container tightly sealed at all times
Shelf Life : 2 to 3 years under correct storage conditions; assess odor quality before use in older stock
Container : Store in original airtight container; glass or HDPE preferred; avoid reactive metals and open containers
Flammability : Flash point ≥ 100°C; not classified as highly flammable under standard handling conditions; keep away from open flames as standard practice
