Polyether L-64 should be stored sealed in a cool, dry, well-ventilated warehouse, protected from light at room temperature, away from heat sources and incompatible substances.

Detailed Description

Polyether L-64 (Poloxamer 184) has certain hygroscopic properties, so keeping the container sealed during storage is crucial. After opening the product, it must be resealed tightly to avoid moisture absorption and external contamination affecting product quality. It is recommended to maintain storage temperature within the room temperature range, avoiding extreme low or high temperatures to prevent irreversible changes in product properties.

The storage area should be away from heat sources, sparks, open flames, and direct sunlight. Although this product is evaluated as a non-hazardous substance according to current hazardous chemical classification standards, it should still be stored separately from incompatible substances such as strong oxidizers, strong acids, and strong bases to ensure storage safety.

Application Advice

When using Polyether L-64 in formulation development, it is recommended to add it during the cooling or dilution stage, with moderate stirring to ensure uniform dispersion. The product is insensitive to hard water ions and can maintain activity over a wide pH range. Under sealed room temperature conditions, the shelf life is stable.

Precautions

  • The product has certain hygroscopic properties; ensure the container is promptly sealed after use.
  • Avoid long-term exposure to extreme temperature and humidity conditions.
  • No eating, drinking, or smoking in the storage area.
  • If the product exhibits abnormal appearance or properties, it is recommended to test and confirm before use.
  • Avoid direct discharge into water bodies, as the product has a low inherent biodegradation rate in the natural environment.
