PEG400DL (Polyethylene Glycol Dilaurate) is a non-hazardous substance with extremely low acute oral toxicity (rat LD50 > 5,000 mg/kg), non-irritating to skin, and only mildly irritating to eyes with reversible effects. Nevertheless, during actual use, standard industrial operating procedures should be followed, and basic personal protective equipment should be worn to ensure occupational health and safety.
During operation, maintain good industrial hygiene practices, and avoid forming aerosols or oil mists. Ensure local effective ventilation before opening containers, and thoroughly wash exposed skin after operation. Although the product has good chemical stability and can be used stably in acidic, alkaline, and hard water media, direct contact with strong oxidizers, strong bases, and strong acids should be avoided to prevent decomposition under extreme conditions.
For storage, it is recommended to store the product in a cool, dry, well-ventilated warehouse, with temperature controlled between 5°C and 40°C. Cloudiness or solidification may occur at low temperatures, which is a normal physical change and does not affect product quality. After returning to room temperature, stir slowly and evenly before normal use. Containers must be sealed immediately after use to prevent moisture absorption or contamination. It is recommended to use original packaging or containers made of compatible materials such as stainless steel or high-density polyethylene.

In cosmetic and personal care formulations, when PEG400DL is used as a solubilizer and auxiliary emulsifier, it is recommended to pre-dissolve it in the oil phase component, stir evenly, and then proceed with emulsification to improve the fineness and system transparency of the emulsion.
In industrial cleaning and metalworking fluid applications, due to its low foam characteristics, it can be directly added to the formulation without additional defoamers. When used as a lubricant component, the recommended dosage should be determined through gradient tests based on specific process requirements.
In pesticide formulations and water-based coating systems, this product can be used as an efficient dispersant. It is recommended to add it during the grinding or high-speed dispersion stage to fully utilize its wetting and dispersing effect on pigments or active substances, thereby improving the storage stability of the system.
