You want a crisp guide you can act on today. Let’s keep it simple, practical, and backed by real specs. We’ll center this around I’Scent—our OEM/ODM workflow, our Fragrance Oils catalog, and what actually moves the needle for brand owners.
IFRA Category 4 and regulatory labeling (EU 2023/1545; US MoCRA)
If your perfume oil is leave-on for skin (roll-on, attar, oil perfume), you’re living in IFRA Category 4. That means you calculate the max safe level for restricted constituents inside your fragrance concentrate, not just the overall fragrance load. Don’t wing it—run the numbers, attach the IFRA certificate for the exact formula batch, and file it with your product dossier.
EU 2023/1545 allergens: expanded allergen list and tight labeling triggers for leave-on. Build labels early; don’t push it to pre-ship week.
US MoCRA: allergen labeling rulemaking is coming into force stages; prepare your disclosure map now.
Documents you actually need on hand: IFRA cert (Cat.4), SDS, COA, Allergen Statement, TDS, and a change-control log.
At I’Scent, every custom mod ships with an updated IFRA certificate and batch COA. Our ERP traceability ties each raw to lot, and lots to finished oil. No guess works.
Blends: add a hint of “character oil” only if it won’t color the accord.
Solvents and diluents: DPG, IPM, TEC selection
DPG (dipropylene glycol): classic diluent to ease blending, useful at modest percentages to reduce haze.
IPM (isopropyl myristate): boosts flow and diffusion, helps dissolve some crystals.
TEC (triethyl citrate): can assist with clarity and volatility control, handy in finicky accords.
Keep it simple first: one carrier, one diluent. If you see clouding or plate-out, run a solubility ladder and adjust IPM/TEC levels before touching the fragrance concentrate.
You can browse ready bases in fine fragrance oils and brief us to tune slip, pick-up, and perceived warmth.
Fixatives and diffusion: Ambroxan, Iso E Super, musks
Fixatives don’t equal “heavy.” They stabilize the trail.
Ambroxan: amber-woody shine, long tail, pairs well with citrus woods.
Iso E Super: radiance and space, clean woody lift; too much can veil florals.
Musks (macrocyclic/linear): body + cushion, but watch for waxy mouthfeel in oil systems.
Resinous notes (labdanum, benzoin): depth and warmth; may raise color—proof labels and bottles.
Start small (1–5% of the total oil formula, depending on the base and IFRA math) and A/B the trail after 4–8 hours on skin.
Stability testing and packaging compatibility (40 °C/75%RH, 5 °C, freeze–thaw)
Oil perfumes still fail if the system isn’t balanced. Run a lean but real program:
Cold: 5 °C (and a freeze–thaw cycle if shipping winter routes).
Light: UV exposure for color-sensitive builds.
Compatibility: test with actual 10 ml glass roll-on and stainless-steel ball; verify no weeping, no drag, no squeak.
Record results. If a mod develops haze at 40 °C, re-balance solvent system first; reformulate the fragrance only if solvation fixes don’t hold.
Recommended starting grids (use as test ladders, then lock with IFRA math)
Use case (用途)
Starting grid
Notes
Comfort skin oil
Fragrance 15–20% + Jojoba/MCT 80–85%
Smooth glide, low projection, everyday wear.
Projection-leaning
Fragrance 20–30% + IPM 50–70% + Carrier 0–20%
Bigger aura; check clarity at cold.
Nature-forward
Natural-heavy fragrance 10–20% + Jojoba 80–90%
Watch allergen labeling; color may deepen.
Need a quick starting point? Pull a close accord from our library and run a 3-mod ladder (low/mid/high load). We’ll cut samples in 1–3 days via custom fragrance oil, then you steer.
Hardware: stainless-steel ball > plastic for glide and wear.
Bottle: glass (clear or amber). Amber reduces perceived color shift complaints.
Label: reserve space for EU allergens and batch; barcode + lot needs to be scannable at warehouse light levels.
Small thing, big pain: cap torque. Over-tightening deforms seats; under-tightening leaks. Lock a torque spec in the SOP.
Quality, traceability, and ISO 22716 GMP
You should expect GMP discipline even for indie-scale volumes:
ISO 22716: documented procedures, training, controlled rooms, calibrated balances.
Batch-to-batch consistency: same olfactive curve within a tolerance window; we check against a retained panel and GC-fingerprint where needed.
Halal: raw screening + segregation prevents cross-contact.
Full traceability: from raw lot to finished case with ERP stamps.
At I’Scent, we run IFRA/ISO/GMP/Halal compliance, and every oil is traceable back to raw drums. If something drifts, we can fix it fast because we see the data fast.
Library pull or build: we pick from 40,000+ formulas or sketch fresh; our 20+ senior perfumers handle both mainstream and niche profiles.
Samples: 1–3 days typical for first mods.
Pilot: stability + compatibility checks.
Scale: 5 kg MOQ for stocked base; 25 kg MOQ for true custom.
Production: 3–7 days after approval; ERP generates batch docs automatically.
Ship: global documents packed (IFRA, SDS, COA, Allergen Statement).
We also run replication when you need a known scent profile. Our match accuracy up to 98% keeps line extensions tight. No over-claim; just consistent work.
