Calone (10% in DPG)

• 10% dilution in DPG for easy integration in oil or alcohol-based formulas
• Adds diffusive marine freshness and watery coolness to top notes
• Ideal for beachy, sporty, unisex, and watery floral compositions
• Blends well with fruits, herbs, aldehydes, and clean musks
• 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

Professional formulation workflow

Calone (10% in DPG) should be evaluated in a controlled small batch before production. Confirm the supplied grade, active concentration and recommended application range from the current supplier documentation. Weigh accurately instead of measuring by drops, record every adjustment, and compare the modified trial against an unchanged control.

Compatibility and quality checks

Test the ingredient in the actual alcohol, oil, surfactant, emulsion or wax base intended for sale. Observe clarity, separation, color, odor and performance immediately after mixing and again after a suitable resting period. A material that looks stable in a concentrate can behave differently in the finished formulation.

Scale-up and safety

Convert percentages into exact batch weights and verify the final consumer-product concentration before scaling. Follow the latest applicable IFRA, cosmetic, chemical and supplier safety documentation for the intended category. Use appropriate protective equipment, ventilation and clearly labeled containers, and retain a sample from every approved batch for quality comparison.
