HEXACHLOROPHENE ICSC: 0161
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE CRYSTALLINE POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes and irritating fumes including hydrogen chloride.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system, resulting in convulsions, respiratory failure.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the nervous system, resulting in tissue lesions, blindness. Animal tests show that this substance possibly causes malformations in human babies.
PHYSICAL PROPERTIES
Melting point: 164-165C
Solubility in water: none
Octanol/water partition coefficient as log Pow: 7.54 (calculated)
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in milk, aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Carrier solvents used in commercial formulations may change physical and toxicological properties. Acigena, Almederm, AT7, AT17, Bilevon, Exofene, Fostril, Gamophen, G-11, Germa-Medica, Hexosan, Septisol, Surofene are trade names.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
