para-tert-BUTYLPHENOL ICSC: 0637
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE, HYGROSCOPIC FLAKES

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 0.08 ppm, 0.5 mg/m; Peak limitation category: II(2); skin absorption (H); sensitization of skin (Sh); Pregnancy risk group: IIc; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes, the skin, and the respiratory tract. The substance may cause effects on the skin, resulting in depigmentation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver, spleen, thyroid and nervous system, resulting in impaired functions.
PHYSICAL PROPERTIES
Boiling point: 237C
Melting point: 98C

Solubility in water: none
Vapour pressure, Pa at 50C: 30
Flash point: 115C o.c.
Octanol/water partition coefficient as log Pow: 2.4-3.4
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
