Section 9: Physical and Chemical Properties

This section identifies physical and chemical properties associated with the substance or mixture. The minimum required information consists of:

• Appearance (physical state, color, etc.);
• Upper/lower flammability or explosive limits;
• Odor;
• Vapor pressure;
• Odor threshold;
• Vapor density;
• pH;
• Relative density;
• Melting point/freezing point;
• Solubility(ies);
• Initial boiling point and boiling range;
• Flash point;
• Evaporation rate;
• Flammability (solid, gas);
• Partition coefficient: n-octanol/water;
• Auto-ignition temperature;
• Decomposition temperature; and
• Viscosity.

The SDS may not contain every item on the above list because information may not be relevant or is not available. When this occurs, a notation to that effect must be made for that chemical property.
