4First-aid measures

First Aid Measures

Inhalation: Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor.
Skin: Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice.
Eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell.
Injection: For an accidental needle-stick: wash the site with soap and water, do not squeeze, cover with a dressing and seek medical advice; report the incident according to your laboratory's sharps procedure.

Most Important Symptoms And Effects

No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption.

Likely Routes Of Exposure

Eye and skin contact from splashes; accidental injection.

5Fire-fighting measures

Fire Fighting Information: Aqueous solution containing 0.9% benzyl alcohol; not flammable.

6Accidental release measures

Spill And Clean Up Procedures: Mop up and rinse the area with water.

7Handling and storage

Safe Handling: Use aseptic technique. Avoid splashes to eyes. Not for use in neonates (benzyl alcohol). Wash hands after handling.
Safe Storage: Store at 20–25 °C (controlled room temperature). Protect from freezing. Discard 28 days after first puncture of the stopper.
Storage Temperature: 20–25 °C; protect from freezing
Incompatible Materials: Strong oxidizing agents (MilliporeSigma 2019; Aldrich 2014); Sigma 305197 lists conditions to avoid: strong heating; sulfuric acid; hydrogen bromide with iron salts.

8Exposure controls / personal protection

Occupational Exposure Limits: Benzyl alcohol: no OSHA PEL, ACGIH TLV or NIOSH REL; AIHA WEEL 10 ppm (44 mg/m³) 8-h TWA. Present at 0.9%.

No occupational exposure limits have been established for the active ingredient(s).
Exposure Controls And PPE: No data available.

9Physical and chemical properties

Physical State

Liquid

Appearance

Clear, colourless to faintly yellow aqueous solution

Properties

Odor: Odourless to faint aromatic odour (benzyl alcohol)
Ph: Approximately 4.5–7.0 (bacteriostatic water, USP) unless adjusted
Melting: About 0 °C (aqueous solution)
Boiling: About 100 °C (aqueous solution)
Flash: Not flammable; aqueous solution (benzyl alcohol flash point 93–101 °C, present at 0.9%)
Vapour: As water (about 2.3 kPa at 20 °C)
Density: About 1.00–1.02 g/mL at 20 °C
Solubility: Aqueous solution; miscible with water
Logp: No data available (hydrophilic peptide)
Decomp: Not applicable (aqueous solution); dissolved peptide degrades on heating

10Stability and reactivity

Stability And Reactivity

Reactivity: Stable under recommended storage conditions; slowly oxidises in air to benzaldehyde/benzoic acid.
Incompatible: Strong oxidizing agents (MilliporeSigma 2019; Aldrich 2014); Sigma 305197 lists conditions to avoid: strong heating; sulfuric acid; hydrogen bromide with iron salts.
Decomposition: Carbon oxides (CO, CO2) in the event of fire (Sigma).
Conditions To Avoid: Strong heating, open flames, contact with strong oxidisers; protect from light and air (Sigma).

Conditions To Avoid

No data available.

Incompatible Materials

No data available.
