Span S-85 (Sorbitan trioleate) is not classified as a hazardous chemical according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). It has no hazard pictograms, signal words, or hazard statements (H-phrases). This means that under normal conditions of use, the product does not pose significant acute health hazards. However, prolonged or repeated contact may still cause mild skin dryness and slight eye irritation, so basic safety awareness is still required during handling.
This product is an amber to brownish-yellow viscous oily liquid with strong lipophilic properties. Due to its high viscosity, spill cleanup can be inconvenient, so care should be taken to avoid tipping containers. Additionally, as a nonionic surfactant, Span S-85 is chemically stable and resistant to acids, alkalis, and hard water, but it should still be kept away from strong oxidizing agents during storage and use to ensure product quality and safety.
According to GHS precautionary statement P280, the following protective measures should be implemented when handling Span S-85:
| Body Part | Required Protective Equipment |
|---|---|
| Hands | Wear chemical-resistant gloves to prevent repeated or prolonged skin contact |
| Eyes | Wear safety goggles to prevent splashes |
| Face/Respiratory | Operate in a well-ventilated area; wear face protection if necessary |
| Accident Type | Response Steps |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and footwear; rinse thoroughly with plenty of water and soap; seek medical attention if irritation persists. |
| Eye Contact | Immediately flush with plenty of water for at least 15 minutes, holding eyelids apart; remove contact lenses if present before continuing; seek medical help if irritation persists. |
| Inhalation | Move the person to fresh air and keep airway clear; seek medical attention immediately if respiratory discomfort occurs. |
| Ingestion | Rinse mouth with water immediately; do NOT induce vomiting; contact a poison control center or seek medical attention immediately. |
| Spill Handling | Small spills: Absorb with inert absorbent materials such as sand, vermiculite, etc., and collect in a sealed container; large spills: Contain by diking to prevent entry into drains or water sources. |
| Firefighting | Suitable extinguishing media: Carbon dioxide, dry powder, foam; firefighters should wear self-contained breathing apparatus and full protective equipment. |
