Purity verification and solvent-free extraction standards.
Technical documentation governing our Chicago apothecary operations: gas chromatography/mass spectrometry (GC/MS) batch testing, Illinois safety compliance, and stable neutral carrier ester formulation.
Verifying chemical purity via gas chromatography batch records in Chicago
Many commercial room scents contain petroleum-derived petrochemical solvents—primarily dipropylene glycol (DPG), diethyl phthalate (DEP), and volatile organic extenders. These compounds are inexpensive, virtually odorless, and dilute active botanical extracts to inflate retail margins. When dispersed through ultrasonic mist misters or aerosol sprayers, they produce persistent airborne particulates that irritate mucous membranes and coat room surfaces.
At Aroma Oil Studio, lead formulator Irina Petrova compounds each lot under a strict solvent-free mandate. Every raw botanical distillation undergoes GC/MS analysis to quantify individual monoterpene, sesquiterpene, and ester percentages.
We decline any raw oil delivery showing chromatographic peaks for synthetic phthalates, synthetic musk fixatives, or residual extraction solvents like hexane. All production runs are logged in our physical register at 720 South Michigan Avenue.

- Lot Verification Hand-Numbered Physical Batch Logs
Balancing small-batch testing costs within fixed catalog reference brackets
Rigorous batch testing adds testing expense, but we maintain fixed unit price brackets based directly on bottle volume and distillation yield rather than charging boutique consulting markups:
- Aroma Oil 1/2 oz: 10–20 USD each. Compact amber bottle formulated for domestic misting and personal space evaluation.
- Aroma Oil 1 oz: 10–25 USD each. Daily ultrasonic formula balanced with neutral botanical carrier; price varies with terpene rarity.
- Aroma Composition 10 mL: 9–13 USD each. Pure concentrated synergistic blend with calibrated 0.05 mL glass dropper.
- Aroma Composition 50 mL: 13 USD each. Large studio flacon designed for continuous hospitality or design office misting.
- Diffuser Refill 9 oz: 20 USD each. Alcohol-free reed replenishment fluid providing ninety days of capillary vapor.
- Room Diffuser: 32 USD each. Assembled amber glass vessel with eight unbleached rattan reeds and pre-measured room liquid.
What the quote depends on: bottle volume; formulation rarity and isolate yield; fraction purity; and whether ready diffuser hardware is required.
- 10 mL Dropper Bracket 9–13 USD шт.
- 1 oz Bottle Bracket 10–25 USD шт.
- 9 oz Refill Bottle 20 USD шт.

Complying with Illinois commercial safety and VOC emission standards
- Corporate Filing Illinois Secretary of State
- Premises Address 720 S Michigan Ave, Chicago
- Flash Point Minimum > 165°F (Pensky-Martens Closed Cup)
- Consumer VOC Limits Compliant under 35 Ill. Adm. Code 223
- Packaging Standard Phenolic Polycone Tight Seal
Commercial fragrance products sold in Illinois are subject to atmospheric emission limits governing Volatile Organic Compounds (VOCs) under 35 Ill. Adm. Code Part 223. Many mass-market room aerosols use high-vapor hydrocarbon propellants (butane and propane) that exceed acceptable municipal VOC thresholds.
Aroma Oil Studio formulates strictly passive liquid systems and non-aerosol cold mist solutions. Because we avoid alcohol-accelerated bases, our diffusion formulas operate well below consumer VOC caps.
Safety Data Sheets (SDS) authored in accordance with OSHA HazCom 2012 / GHS standards are retained for every formulation in our catalog. These sheets document flashpoints, dermal sensitization thresholds, and aquatic profile metrics for commercial trade clients.
Engineering carrier ester stability against oxidation and terpene rancidity
Medium-Chain Triglyceride Solubilization
We select pharmaceutical-grade caprylic/capric triglycerides derived from cold-pressed neutral plant sources. These ester chains lack double bonds, completely eliminating oxidative rancidity over twenty-four months of storage.
Amber Photoprotective Packaging
Monoterpenes such as limonene and pinene degrade into irritating peroxides when exposed to ultraviolet radiation between 300 nm and 400 nm. We bottle exclusively in USP Type III amber glass that filters out over 99% of actinic daylight.
Nitrogen Flush Headspace Displacement
Flacons filled in our Chicago workshop have their neck air displaced with food-grade gaseous nitrogen prior to phenolic closure application. Displacing atmospheric oxygen stops terpene auto-oxidation in transit.
Tamper-Evident Phenolic Closures
Our caps incorporate conical polyethylene polycone liners that seat into the bottle bore. This creates a mechanical hermetic seal that prevents micro-leakage and aroma bleed even under airline baggage pressure differentials.
Addressing formulation boundaries and natural variation across harvests
Working with pure botanical fractions means accepting natural seasonal variation. Here is what industrial synthetic fragrance marketing conceals and what our studio states openly:
Color variations between batches: Because we do not add synthetic blue or purple dyes to standardize liquid color, our lavender distillates vary from clear water-white to pale straw gold depending on harvest rainfall. Bergamot fractions range from soft chartreuse to bright amber.
Viscosity adjustments: Heavy woody sesquiterpenes (like Australian sandalwood and Atlas cedarwood) move through pipettes at slower flow rates than citrus monoterpenes. We calibrate dropper apertures so that one drop consistently dispenses 0.05 mL (±0.005 mL).
To calculate exact drop dosages for your equipment and square footage, use our interactive diffuser dosage calculator. For trade or commercial hospitality supply inquiries, visit commercial & studio fragrance supply.
