Question 6

How to store PEG400DL (Polyethylene Glycol Dilaurate)? What is its shelf life?

Accepted Answer

PEG400DL should be stored sealed in a cool, dry environment at 5°C to 40°C. The official nominal shelf life data is not yet included in the database, but the product exhibits excellent stability under compliant storage conditions; it is recommended to use it preferentially within 12 months of receipt. Detailed Description The storage management of PEG400DL (Polyethylene Glycol Dilaurate) directly affects its performance and product life. According to the safety instructions of Guoli Chemical, this product should be stored in a cool, dry, and well-ventilated warehouse, with the recommended storage temperature strictly controlled between 5°C and 40°C. Special attention is required: under low-temperature conditions, the product may appear cloudy or solidified, which is a normal physical state change and does not affect product quality or chemical performance at all—simply bring the product to room temperature and stir slowly until uniform, then it can be used normally. Container management is a key point in the storage process. PEG400DL should be stored in original sealed packaging or confirmed compatible material containers (such as stainless steel, high-density polyethylene). After each use, the container must be immediately tightened to prevent moisture absorption or contamination. The warehouse should be kept away from strong oxidizers, strong bases, strong acids, and other incompatible substances, and avoid contact with open flames and high-temperature surces (the flash point of this product is >250°C; although it is a high-flash-point material, the risk of decomposition at high temperatures still needs to be guarded against). Regarding the shelf life issue: The product database you consulted does not yet include the specific official nominal shelf life value for PEG400DL. However, from the chemical nature of the product, PEG400DL is a saturated tty acid ester nonionic surctant with a stable molecular structure. Under sealed and light-protected conditions at 5~40°C, it is not prone to hydrolysis or oxidative deterioration, and its actual shelf life is relatively long. As a general industry recommendation, it is advised to use it preferentially within 12 months of receipt; if storage exceeds this period, it is recommended to re-test the appearance, pH value (1% aqueous solution should be 5.0~7.0), and acid value (≤1.0 mgKOH/g) before use, and the product can still be used after confirming no abnormalities. Technical Parameters ParameterValue Recommended Storage Temperature5°C ~ 40°C Low-temperature PhenomenonCloudiness or solidification (normal, reversible) Recommended Container MaterialStainless steel, High-density polyethylene (HDPE) Flash Point (Closed Cup)>250°C HygroscopicityHygroscopic, must be stored sealed Chemical StabilityStable under normal conditions, avoid strong acids and bases Incompatible MaterialsStrong oxidizers, strong bases, strong acids Application Recommendations Whether you use PEG400DL in cosmetic formulations, industrial cleaners, or pesticide formulations, check the product appearance before use: the normal product should be a light yellow transparent to slightly cloudy liquid. If the product solidifies after low-temperature transportation or winter storage, do not directly heat it or use an open flame. The correct method is to place the sealed container in an environment at 20~30°C to naturally warm up for 12~24 hours; after it regains fluidity, stir slowly until uniform and then use. Precautions Sealing is the core principle: PEG400DL is hygroscopic. If left exposed to the air for a long time after opening, it may absorb moisture from the environment, diluting the active ingredient, and in severe cases, may induce microbial growth. It is recommended to divide into smaller containers for use to reduce frequent opening of large drums. Keep away from incompatible materials: Contact with strong oxidizers (such as peroxides, concentrated nitric acid) may cause violent reactions; the storage area should be segregated. Packaging specifications reference: Guoli Chemical provides two standard packaging options: 50 kg plastic drum and 200 kg plastic drum. For bulk storage, it is recommended to keep the original packaging to avoid repeated drum transfers. Disposal: Products that have exceeded their shelf life or are confirmed to be deteriorated should be disposed of as chemical waste by qualified units in accordance with local regulations; do not discharge into sewers or surce waters.

In personal care formulations, it is often paired with tty acid esters and tty alcohol ethers. Process Temperature: Suitable for both cold and hot processing. If the material appears turbid or solidified during low-temperature operations, allow the product to return to room temperature (15~30°C) and stir slowly until uniform. This does not affect performance. pH Applicability Range: It remains stable in acidic, alkaline, and hard water media, with a wide applicable range. Precautions It is recommended to wear protective goggles and chemical-resistant gloves (such as nitrile gloves) during operation to avoid prolonged skin contact and eye splashes. Storage temperature is recommended to be 5°C to 40°C, away from strong oxidizers, strong acids, strong bases, open flames, and high-temperature sources. After use, seal the container promptly to prevent moisture absorption or contamination. It is recommended to use containers made of stainless steel or high-density polyethylene (HDPE). Although the product is readily biodegradable, uncontrolled large-scale environmental release should be avoided. Waste should be disposed of by a qualified organization.

Question 10

What are the physicochemical technical parameters of PEG400DL (Polyethylene Glycol 400 Dilaurate)?

Accepted Answer

PEG400DL (Polyethylene Glycol 400 Dilaurate) is a nonionic surctant, whose core physicochemical parameters cover multiple dimensions such as appearance, HLB value, acid value, hydroxyl value, viscosity, and density. The parameters are comprehensive and suitable for various industrial formulation systems. Detailed Description PEG400DL is produced by the esterification reaction of polyethylene glycol 400 and lauric acid. It appears as a colorless to slightly yellow transparent viscous liquid (cloudiness or solidification may occur at low temperatures, which is a normal physical phenomenon; after returning to room temperature and stirring evenly, it can be used). The product has a molecular weight of approximately 400, CAS number 9005-02-1, belongs to nonionic surctants, with an HLB value of about 20, strong hydrophilicity, excellent solubility in water, and also soluble in organic solvents such as ethanol and acetone. The active content and solid content of this product are both ≥99%, moisture content ≤0.5%, exhibiting high purity characteristics. Its acid value and saponification value are both controlled at ≤1.0 mgKOH/g, hydroxyl value range is 264~290 mgKOH/g, reflecting extremely low free tty acid content and sufficient esterification reaction. Iodine value ≤1.0, unsaturation ≤0.1, indicating almost no unsaturated double bonds in the molecular structure, with excellent chemical stability and antioxidant capacity. In terms of physical properties, the density of PEG400DL is 1.11~1.13 g/cm³, kinematic viscosity is 90~110 mm²/s (low shear viscosity at 25°C is 100~200 mPa·s), refractive index is 1.466~1.468. Flash point is higher than 200°C (closed cup method >250°C), melting point is lower than 5°C, making it a high flash point, low freezing point safe liquid. The pH value of a 1% aqueous solution is 5.0~7.0, and that of a 5% aqueous solution is 4.5~7.5, close to neutral, gentle on skin and metal contact. The foam performance of the product is low foaming, surce tension is about 60 mN/m, suitable for industrial formulations requiring low foam characteristics.
