  • Sorbitan tristearate is a non-ionic surfactant, with a synergistic effect on skin permeability. Sorbitan tristearate can be used as an excipient, such as emulsifier. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1][2].

Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical attention if irritation occurs.
Skin ContactWash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation
develops.
Serious Skin ContactNot available.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention.
Serious InhalationNot available.
IngestionDo NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an
unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen
tight clothing such as a collar, tie, belt or waistband.

Section 6. Accidental Release Measures
Small SpillAbsorb with an inert material and put the spilled material in an appropriate waste disposal.
Large SpillAbsorb with an inert material and put the spilled material in an appropriate waste disposal. Finish cleaning by
spreading water on the contaminated surface and allow to evacuate through the sanitary system.

Section 7. Handling and Storage
PrecautionsKeep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not
breathe gas/fumes/ vapor/spray.
Keep container tightly closed. Keep container in a cool, well-ventilated area.
Storage

Section 8. Exposure Controls/Personal Protection
Engineering ControlsProvide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below
their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the
work-station location.
Personal ProtectionSafety glasses. Synthetic apron. Gloves (impervious). Respiratory protection is not necessary for normal
handling. Good room ventilation or use of local exhaust (fume hood) is sufficient. Use a vapor respirator
under conditions where exposure to the substance is apparent (e.g. generation of high concentrations of mist
or vapor, inadequate ventilation, development of respiratory tract irritation), and engineering controls are not
feasible. Be sure to use an approved/certified respirator or equivalent.
Personal Protection in Case of Splash goggles. Full suit. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a
a Large Spillspecialist BEFORE handling this product.
