Thymol Crystals Thymol

Thymol (also known as 2-isopropyl-5-methylphenol, IPMP) is a natural monoterpenoid phenol derivative of cymene, C10H14O, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris (common thyme) and various other kinds of plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol has been used in alcohol solutions and in dusting powders for the treatment of tinea or ringworm infections, and was used in the United States to treat hookworm infections. It is also used as a preservative in halothane, an anesthetic, and as an antiseptic in mouthwash. Thymol is also the active antiseptic ingredient in some toothpastes. Thymol can also be used as a medical disinfectant and general purpose disinfectant.

Thymol USP NF Grade Specifications
C10H14O 150.22
Phenol, 5-methyl-2-(1-methylethyl)-.
p-Cymen-3-ol [CAS 89-83-8].

Thymol contains not less than 99.0 percent and not more than 101.0 percent of C10H14O.

Packaging and storage: Preserve in tight, light-resistant containers.

A: Infrared Absorption 197K .
B: It meets the requirements under Melting range.
Melting range: between 48 and 51C; but when melted, Thymol remains liquid at a considerably lower temperature.
Limit of nonvolatile residue: Volatilize about 2 g, accurately weighed, on a steam bath, and dry at 105 to constant weight: not more than 0.05% of residue remains.
Assay: Transfer about 100 mg of Thymol, accurately weighed, to a 250-mL iodine flask, and dissolve in 25 mL of 1 N sodium hydroxide. Add 20 mL of hot dilute hydrochloric acid (1 in 2), and immediately titrate with 0.1 N bromine VS to within 1 to 2 mL of the calculated endpoint. Warm the solution to between 70 and 80 , add 2 drops of methyl orange, and continue the titration slowly, swirling vigorously after each addition. When the color of the methyl orange is bleached, add 2 drops of 0.1 N bromine, shake for 10 seconds, add 1 drop of methyl orange, and shake vigorously. If the solution is red, continue the titration, drop-wise and with shaking, until the color is discharged. Repeat the alternate addition of the titrant and the methyl orange until the red color is discharged. Each mL of 0.1 N bromine is equivalent to 3.755 mg of C10H14O.

5. Fire Fighting Measures

Flammability of the Product: Non-flammable. However, it may burn at high temperature.
Products of Combustion: Carbon oxides.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

6. Accidental Release Measures

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental  precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Avoid touching the spilled material. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Do not contaminate the environment.

7. Handling and Storage

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Do not ingest. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents. Moisture sensitive.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits: This product, as supplied, does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice.
