L-62 Poloxamer is a low-toxicity, low-hazard non-dangerous substance, but during operation, special attention should be paid to protecting the eyes and skin. Avoid direct contact to ensure safe use.

Detailed Description

According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) assessment, L-62 Poloxamer (CAS No.: 9003-11-6) is classified as Skin irritation category 2 (H315) and Serious eye damage/eye irritation category 2 (H319). This means that the product does not have serious hazards such as acute toxicity, carcinogenicity, or reproductive toxicity, but it may still cause local skin discomfort and significant eye irritation during use, requiring protection.

From toxicological data, the acute oral toxicity LD₅₀ (rat) of this product is greater than 5,000 mg/kg, which is actually non-toxic. Available data also indicate no skin sensitization, no germ cell mutagenicity, and no evidence of carcinogenicity in long-term studies. Therefore, the overall safety of L-62 Poloxamer is relatively high, but good operating practices remain key to ensuring personnel safety.

In terms of environmental safety, L-62 Poloxamer is readily biodegradable, has low toxicity to aquatic organisms, is not persistent in the environment, and does not exhibit significant bioaccumulation potential. Under normal use and proper disposal conditions, the risk of environmental impact is low.

Core Safety Operation Requirements

Personal Protective Equipment (PPE)

  • Eye Protection: Wear safety goggles compliant with EN 166 standards to prevent splashes from entering the eyes.
  • Hand Protection: Wear appropriate protective gloves to avoid direct skin contact.
  • Respiratory Protection: Ensure good ventilation in the workplace; if dust or aerosols are generated, wear a particulate respirator meeting NIOSH N95/EN 149 FFP2 standards.
  • Hygiene Practices: After operation, thoroughly wash hands and exposed skin with mild soap and clean water. Do not use solvents. Eating, smoking, and drinking are prohibited in the workplace.

Storage Requirements

  • Store in a cool (recommended temperature 5~30°C), dry, and well-ventilated warehouse.
  • Keep containers tightly sealed, away from heat sources, sparks, and open flames (flash point above 200°C, not flammable).
  • Keep away from incompatible substances such as strong oxidizers, strong acids, and strong bases.
  • Use original containers or sealed containers made of compatible materials (stainless steel, glass, polyethylene) to avoid moisture and water vapor.

Emergency Procedures

  • Skin Contact: Immediately remove contaminated clothing and rinse skin with plenty of water and mild soap for at least 15 minutes. If irritation persists, seek medical attention.
  • Eye Contact: Immediately hold eyelids open and rinse slowly and thoroughly with room-temperature water for at least 15 minutes, periodically turning the eyeball. Remove contact lenses if worn and easy to do so. Seek immediate medical attention.
  • Inhalation: Move the affected person to fresh air quickly and keep breathing unobstructed. If symptoms such as coughing or discomfort occur, seek medical advice.
  • Ingestion: Rinse the mouth with water, do not induce vomiting. Seek medical attention immediately and present this product description or container label.
  • Spill Cleanup: Sweep or shovel up the spilled material and collect it in a dry, covered, and clearly labeled container. Use inert absorbent materials to treat residues and dispose of in accordance with local regulations. Prevent entry into drainage systems or waterways.

Application Recommendations

L-62 Poloxamer performs excellently in applications such as industrial and institutional cleaning, metalworking fluids, agrochemicals, and emulsion polymerization. However, safety management focuses vary slightly in different scenarios:

  • Industrial batching operations: Splashes are prone to occur during feeding and transfer processes, making eye and hand protection the top priority. It is recommended to operate in well-ventilated batching areas.
  • Automatic dishwasher rinse aid formulations: The dosage of L-62 in the finished product is usually low (0.5%~5%), posing very low risk for end consumers during normal use. However, the above protection requirements must still be followed during formulation production.
  • Metalworking fluids: The working fluid concentration generally does not exceed 5%. When used in open systems, attention should be paid to ventilation in the work area to avoid prolonged skin contact with the diluted working fluid.
  • Pesticide formulation processing: Processing may involve other highly toxic active ingredients, and the overall safety risk of the entire formulation should be comprehensively assessed. The low toxicity of L-62 alone should not be used to reduce the overall protection level.

Precautions

  • Users are responsible for conducting a risk assessment for the application of this product in their specific workplace and establishing corresponding safe operating procedures. The above safety instructions do not constitute a product performance guarantee.
  • For detailed disposal measures, please refer to the complete Safety Data Sheet (SDS/MSDS) of the product separately.
  • Waste disposal must be carried out in accordance with local, regional, and national environmental regulations. Do not discharge into waterways, sewers, or soil. Residual materials should be sent to qualified waste treatment service providers for incineration or sanitary landfill.
