BUTYL BENZOATE

Butyl Benzoate is an aromatic ester formed from benzoic acid and butyl alcohol and is used as a solvent, fragrance ingredient, and formulation aid in multiple industries.
Butyl Benzoate is widely used to improve solvency for resins, polymers, and aromatic materials, and it is also used to modify odor profiles in fragrance and flavor-related applications where permitted.
Butyl Benzoate is valued for good solvency power, pleasant mild odor character, relatively low volatility compared with lighter solvents, and usefulness as an intermediate and carrier in specialty formulations.

DESCRIPTION

Butyl Benzoate is typically a clear, colorless to pale yellow liquid with a mild, sweet, balsamic-like odor.
Butyl Benzoate is an aromatic ester that provides good solvency for many resins, fragrances, and lipophilic materials.
Butyl Benzoate has relatively low water solubility and is more compatible with oils, esters, and many organic solvents.

Butyl Benzoate can be used as a diluent to reduce viscosity in fragrance oils and resin solutions.
Butyl Benzoate evaporation rate is slower than many light solvents, which can help reduce fast-dry defects and improve leveling.
Butyl Benzoate can contribute to odor profile in perfumery, often providing a soft, slightly fruity-balsamic background note.

Butyl Benzoate is generally stable under normal storage conditions but should be kept away from strong oxidizers.
Butyl Benzoate should be handled with good industrial hygiene practices to avoid unnecessary skin and eye contact.
Butyl Benzoate should be stored in tightly closed containers to minimize contamination and maintain consistent quality.

Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Do not induce vomiting unless directed by medical personnel.
Seek medical attention if a large amount is swallowed or discomfort occurs.

Note to Physicians:
Treat symptomatically.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses.
Avoid generating aerosols or mists during transfer and mixing.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use local exhaust or general ventilation where vapors or mists may be generated.
Provide adequate ventilation during heating, spraying, or high-shear mixing operations.
Avoid prolonged exposure to concentrated vapors in enclosed areas.

Storage:
Store in a cool, dry, well-ventilated area in tightly closed containers.
Keep away from heat, sparks, open flames, and strong oxidizers.
Keep containers properly labeled and prevent contamination during repeated opening.

Spill and Leak Procedures:
Contain the spill and absorb with inert material such as sand or universal absorbent.
Clean residue with detergent and water while preventing slip hazards.
Dispose of waste according to local regulations and facility procedures.

Handling Precautions:
Use closed transfer systems when feasible to reduce vapor and odor exposure.
Avoid unnecessary heating and minimize ignition sources due to combustible liquid nature.
Rotate stock using FIFO practices to maintain consistent quality and performance.
