OP-40 Octylphenol Polyoxyethylene Ether should be stored in a cool, dry, well-ventilated warehouse (5°C to 30°C), keeping the container tightly closed; the specific shelf life shall be subject to the product label. Under recommended conditions, unopened original packaging can typically be stored stably for 1-2 years.

Detailed Description

OP-40 Octylphenol Polyoxyethylene Ether is a nonionic surfactant with relatively stable chemical properties, but storage conditions directly affect its quality and performance. According to the product safety data sheet provided by Guoli Chemical, this product should be stored in a dedicated warehouse that is cool, dry, and well-ventilated, away from heat sources, sparks, and open flames. The container must be kept tightly closed to avoid contact with moisture or impurities in the air.

The storage temperature is recommended to be strictly controlled between 5°C and 30°C, avoiding extreme temperature fluctuations. Temperatures that are too low may cause the product's viscosity to increase or even lead to cloudiness or solidification, while excessive temperatures may accelerate product oxidation or degradation, affecting emulsifying performance and detergency. Additionally, the product should be protected from direct sunlight and moisture, as UV exposure and water ingress can cause product deterioration.

Shelf Life Explanation

According to data from Guoli Chemical, under recommended storage conditions, unopened original packaging products can maintain stable quality within the shelf life indicated on the label. The specific shelf life shall be based on the product label. Generally, nonionic surfactant products, when stored correctly in unopened original packaging, have a typical shelf life of 1-2 years from the date of manufacture. It is recommended to follow the principle of "best used within the shelf life if the original container remains unopened." Once opened, the product should be used as soon as possible, and the container should be immediately resealed after each use to minimize exposure to air.

Precautions

  • Do not discharge the product or its container directly into soil, waterways, or drainage systems to prevent toxic hazards to aquatic organisms (H410).
  • Emergency shower equipment and eyewash stations should be installed in the storage area and kept in working condition.
  • If the product exceeds the shelf life stated on the label, performance testing should be conducted before use to confirm that key indicators such as emulsification and dispersion still meet requirements.
  • If a product that has been opened and stored for a long time shows abnormal phenomena such as stratification, cloudiness, or off-odors, it should be discontinued and disposed of by a professional agency.
  • Waste products and packaging must be handled in accordance with hazardous waste management regulations and sent to qualified professional agencies for recycling or disposal.
