According to the technical data from Guoli Chemical, the core advantage of PEG400DL (polyethylene glycol dilaurate) compared with similar products is that it integrates high emulsifying power, low-foaming characteristics, excellent chemical stability, and wide application compatibility, making it a nonionic surfactant with very balanced comprehensive performance.
In detail, the advantages of PEG400DL are reflected in the following aspects:
1. Excellent Comprehensive Performance
Unlike some emulsifiers with single function, PEG400DL not only provides high emulsifying ability but also possesses outstanding dispersion, solubilization, and low-foaming properties. This means it can simplify formulations, sometimes achieving ideal effects without adding multiple auxiliary agents. This advantage is particularly prominent in industrial cleaning and metalworking fluids that require low foaming.
2. Superior Formulation Stability and Compatibility
Its molecular structure gives it wide compatibility. According to Guoli Chemical's technical data, PEG400DL maintains stable performance in acidic, alkaline, and hard water media, and is not easily decomposed or inactivated. This makes it more reliable than many other ester emulsifiers in complex formulation environments (e.g., acidic cleaners or alkaline textile auxiliaries). Moreover, it can be well compounded with anionic, cationic, and other nonionic surfactants, providing great design flexibility for formulators.
3. Broad Application Fields
Its balanced performance makes it widely applicable, capable of meeting formulation needs across multiple industries.
- Cosmetics field: It can serve as an efficient solubilizer and auxiliary emulsifier, helping transparent products remain clear and providing a non-sticky skin feel.
- Industrial field: It acts as a low-foaming emulsifier in cleaners and as a lubricating component in metalworking fluids.
- Textile and agriculture: It can be used as an antistatic agent, softener, and pesticide emulsifying dispersant, exhibiting strong cross-industry adaptability.
4. Excellent Safety and Environmental Characteristics
The safety data of Guoli Chemical's PEG400DL is outstanding, which is one of its core advantages:
- Very low toxicity: Acute oral toxicity LD50 > 5,000 mg/kg, very safe.
- High mildness: Non-irritating to skin, only reversible mild irritation to eyes.
- Environmentally friendly: Readily biodegradable product (OECD 301F, 28-day degradation rate > 60%), meeting the high standards of modern industry for green and sustainable development, reducing post-treatment environmental pressure.
For a more intuitive comparison, here is a table comparing its key advantages with general industry requirements:
| Advantage Dimension | Specific Performance of PEG400DL (Guoli Chemical) | Application Advantage Description |
| :--- | :--- | :--- |
| Emulsifying Performance | Can effectively reduce oil-water interfacial tension, forming stable and fine emulsions | Suitable for various oil phase systems, strong formulation adaptability, high emulsion stability |
| Foaming Characteristics | Low foam | Especially suitable for industrial circulating cleaning and metalworking fluids, easy to rinse, saving water |
| Chemical Stability | Stable in acid, alkali, and hard water | Expands application scenarios, longer formulation life, less affected by water quality fluctuations |
| Safety/Mildness | Non-irritating to skin, mild and reversible eye irritation, very low toxicity | Suitable for personal care products, ensures occupational safety, reduces consumer risk |
| Environmental Friendliness | Readily biodegradable (28-day degradation rate > 60%) | Meets EU environmental standards, low wastewater treatment burden, conforms to sustainable development procurement requirements |
Application Recommendations
- Cosmetics: Recommended as a solubilizer for fragrances, essential oils, or active ingredients; typical dosage is 3-5 times the amount of active ingredient. In creams and lotions, it can be used as an auxiliary emulsifier to improve skin feel.
- Industrial Low-Foaming Cleaners: Can be used as one of the main surfactants; recommended usage concentration is 1%-5%, effectively emulsifying and removing oil stains, and easy to rinse.
- Metalworking Fluids: As a lubricating and emulsifying component, recommended addition is 2%-10% of the total formulation.
Precautions
- Although PEG400DL has good stability, it is still recommended to conduct thorough compatibility tests during formulation design to ensure long-term stable coexistence with all other components in the system.
- The product may become turbid or solidify at low temperatures (below 5°C). This is a normal physical phenomenon and does not affect product quality. When using, bring it to room temperature and stir slowly and evenly.
