Low-foam penetrant SF is not classified as a dangerous chemical and has high safety under normal use conditions, but basic chemical protection regulations should still be followed to avoid direct contact and maintain good ventilation.
Detailed Explanation
Low-foam penetrant SF does not fall under the physical, health, or environmental hazard categories defined by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Toxicological data indicate low acute toxicity: acute oral toxicity (rat) LD50 > 2000 mg/kg bw, acute dermal toxicity (rat) LD50 > 2000 mg/kg bw. The skin irritation score in rabbits is less than 0.5, indicating no skin irritation. This product is a non-flammable liquid, making storage and transportation relatively safe.
Although this product has an ideal safety profile, as an industrial chemical, caution should still be exercised during handling. Operators should wear chemical safety goggles, protective gloves, and general work clothes to avoid prolonged direct contact with eyes, skin, and mucous membranes. After operation, hands and any exposed areas must be thoroughly washed with water and soap. The workplace should be well-ventilated to prevent the formation of continuous aerosols or vapor accumulation.
Keep away from heat sources and ignition sources during use. Do not eat, drink, or smoke at the operation site. Empty containers may contain product residues and must not be used to store other substances without professional cleaning. It is recommended that all operators receive basic chemical safety training and master necessary emergency response methods.

Application Recommendations
Low-foam penetrant SF is widely used in textile pretreatment, industrial cleaning, paper deinking, leather processing, and pesticide synergism. In various application scenarios, it is recommended to use under well-ventilated conditions and prepare working solutions at appropriate concentrations according to specific process requirements. Due to its excellent stability in acid, alkali, and hard water environments, it can be applied in processes with different pH requirements.
Storage Precautions
- Store in a cool, dry, well-ventilated dedicated warehouse, avoiding direct sunlight.
- Keep containers sealed to prevent moisture absorption or entry of foreign matter.
- Storage temperature should be controlled between 5°C and 35°C, away from heat sources, ignition sources, and incompatible materials such as strong oxidizers.
- Do not store together with food, feed, or drinking water. The warehouse should be equipped with spill containment facilities (such as leak-proof trays).
- Regularly check the integrity of packaging. If leakage is found, transfer immediately and handle properly.
First Aid and Emergency Measures
- Skin contact: Immediately remove contaminated clothing and rinse with plenty of water and soap for at least 15 minutes. If irritation occurs, seek medical attention.
- Eye contact: Immediately open eyelids and rinse continuously with water or saline for at least 15 minutes, and seek medical treatment.
- Inhalation: Move the affected person to fresh air, maintain an open airway. If discomfort persists, seek medical attention.
- Ingestion: Do not induce vomiting. Rinse the mouth thoroughly with water and drink an appropriate amount of water to dilute. Seek medical attention promptly.
- Spill handling: For small spills, cover and collect with inert absorbent materials (such as vermiculite, sand). For large spills, dike and contain to prevent entry into drains or waterways. Dispose of waste materials through qualified waste treatment agencies according to local regulations. Do not discharge into the environment.
- Firefighting measures: This product is a non-flammable liquid, but in a fire, it may decompose and produce harmful gases. Firefighters should wear self-contained breathing apparatus and full protective clothing. Suitable extinguishing media include water fog, carbon dioxide, dry powder, and foam.
