Emulsifier MOA-3B should be stored in a cool, dry, and well-ventilated warehouse, with temperature maintained between 5°C and 40°C, and kept sealed; there is no specific shelf life data in the product database, it is recommended to use within 12 months under appropriate storage conditions.

Detailed Description

Emulsifier MOA-3B (fatty alcohol polyoxyethylene (3) ether) is a nonionic surfactant produced by Guoli Chemical, with stable chemical properties, active content ≥ 99%, and water content ≤ 1.0%, belonging to a high-purity product. Due to its nonionic nature, it has good tolerance to acids, alkalis, and hard water. Under proper storage conditions, it is not prone to chemical degradation or stratification, and can maintain its core properties such as emulsification, wetting, and dispersion for a long time.

Regarding shelf life, there is no specific shelf life marked data in the product database. According to industry practices for nonionic surfactants and the chemical stability characteristics of this product, under the premise of strictly following the recommended storage conditions, it is suggested to use within 12 months from the date of manufacture to ensure optimal application effects. For products exceeding the recommended usage period, key indicators such as appearance, pH value (1% aqueous solution should be 5.0~7.0), and moisture content (should be ≤ 1.0%) should be re-tested before use, and the product can only be used after confirming compliance.

Application Suggestions

Before use, it is recommended to check the product appearance; the normal product should be a colorless to light yellow transparent liquid. If abnormalities such as turbidity, stratification, precipitation, or significant darkening of color occur, it may indicate that the product has been dampened or deteriorated, and it is not recommended to continue use. Unused product after opening the drum should be resealed as soon as possible to avoid prolonged exposure to air and moisture absorption. In low-temperature winter environments, the product viscosity may increase; if slight turbidity occurs, it can be naturally restored at room temperature without special heating treatment.

Precautions

  • Although this product has good chemical stability, prolonged storage above 40°C may cause darkening of color and pH drift, affecting performance.
  • Product flash point > 150°C, not classified as flammable liquid, but still should be kept away from open flames and high-temperature sources.
  • Packaging containers should be used up as soon as possible after opening to avoid repeated opening leading to ingress of moisture and impurities.
  • Strictly follow the "first in, first out" inventory management principle to ensure product is used within the optimal period.
  • To obtain precise shelf life data or batch information, it is recommended to contact Guoli Chemical technical team and provide the specific batch number for inquiry.
