Polyethylene Glycol PEG-4000/6000 series (CAS No.: 25322-68-3) is a non-ionic high molecular polymer, appearing as a white to slightly yellow waxy solid or flakes. Its molecular structure combines both hydrophilicity and hydrophobicity, enabling it to exhibit excellent compatibility and functionality in various industrial formulations, making it an indispensable multifunctional additive in fields such as pharmaceuticals, daily chemicals, textiles, rubber, and papermaking.
The greatest highlight of this product lies in its "trinity" comprehensive performance: Firstly, it has outstanding compatibility, capable of playing multiple roles such as emulsification, wetting, dispersion, and solubilization, effectively enhancing the stability and uniformity of formulations; secondly, its chemical stability is extremely outstanding, remaining stable over a wide pH range and showing excellent tolerance to acids, alkalis, and hard water environments, making it reliable under complex working conditions; finally, it also possesses good functionality, providing ideal lubrication, moisturizing, and shaping effects, serving as a key component in fine product formulations, especially valuable in applications requiring precise control of product texture and user experience.
From a safety perspective, PEG-4000/6000 is a low-toxicity substance (acute oral LD50 greater than 5000 mg/kg) and is classified as a non-hazardous material, offering reliable safety assurance for its use in fields such as pharmaceuticals and daily chemicals that involve direct contact with the human body. However, it should be noted that its fine dust, when mixed with air to a certain concentration, may pose an explosion risk, so proper ventilation and dust control should be implemented during production operations.

With its multifunctional properties, PEG-4000/6000 has clear application positioning across various industries:
1. This product has strong hygroscopicity, so it must be promptly sealed after opening and stored in a cool, dry, and ventilated place away from strong oxidizers.
2. Pay attention to dust control during operation; keep the work area away from open flames and high-temperature surfaces, and it is recommended to wear dust masks and protective gloves.
3. Avoid generating dust during pouring and mixing of the powder product, use non-sparking tools for handling, and prevent the risk of dust explosion.
