Octadecylamine Polyoxyethylene Ether AC-1830 should be stored sealed in a cool, dry, and well-ventilated warehouse. The storage temperature is recommended to be ≤40°C, avoiding moisture and high temperature. Under proper storage conditions, it is recommended to use within 1 year from the date of manufacture to ensure optimal product performance.

Detailed Storage Methods

Octadecylamine Polyoxyethylene Ether AC-1830 should be stored in a cool, dry, and well-ventilated dedicated warehouse. The packaging container must be kept tightly sealed to prevent the product from absorbing moisture and being contaminated. The storage temperature is recommended to be controlled within ≤40°C, while avoiding freezing of the product, as the product form (paste or solid) will change with temperature. The freezing point is about 20-30°C, which is a normal physical phenomenon and does not affect performance.

The storage area should be away from fire and heat sources, and smoking is strictly prohibited. This product should be kept away from incompatible substances such as strong oxidizers and strong acids. The warehouse should be equipped with appropriate spill containment facilities to prevent accidental leakage. The product packaging adopts 50kg plastic drums, 200kg plastic drums, or IBC totes. During loading and unloading, handle with care to avoid container damage.

Since this product has certain hygroscopicity, the container should be resealed in time after opening. Operators should wear protective gloves and goggles, maintain workplace hygiene, and thoroughly wash hands after operation.

Shelf Life Description

This product has no mandatory legal shelf life and is a nonionic surfactant with good chemical stability. There is no nominal shelf life data for AC-1830 in the Guoli Chemical product database. According to industry practice, under the above storage conditions, it is generally recommended to use within 12 months from the date of manufacture to ensure optimal performance in emulsification, wetting, dispersion, etc. For expired products, it is recommended to verify performance before use.

For each specific batch, it is recommended that users check the production batch number and manufacturing date on the product packaging, or contact the Guoli Chemical sales/technical department for the recommended usage period for that batch.

Application Recommendations

To ensure product performance, it is recommended to follow the "first in, first out" inventory management principle to avoid long-term accumulation. If slight delamination or appearance changes occur after long-term storage, the product can be restored by appropriate heating and stirring before use (e.g., water bath heating at 50-60°C). However, if severe discoloration, odor, or signs of deterioration appear, discontinue use.

Precautions

  • This product is hygroscopic. After opening, be sure to seal the container promptly to prevent moisture ingress and increase in water content.
  • Avoid prolonged exposure to high temperatures (>40°C) and direct sunlight to prevent oxidative degradation of the product.
  • The storage and handling area should be equipped with spill emergency response materials (such as inert absorbent materials, protective equipment).
  • This product is a general chemical and should be loaded, unloaded, and transported according to conventional chemical transportation requirements.
