Is XPO-4 (glycerol polyoxyethylene ether oleate), a high-temperature leveling agent, environmentally friendly? Can a test report be provided?

XPO-4 has good overall environmental performance and is an easily biodegradable nonionic surfactant. However, attention should be paid to its potential hazards to aquatic organisms. Specific test reports can be obtained directly from Guoli Chemical.

Detailed Description

XPO-4 (glycerol polyoxyethylene ether oleate) performs relatively prominently in terms of environmental compliance. According to the ecotoxicological data in Guoli Chemical's product database, the biodegradation rate of this product is greater than 70% (OECD 301B method) , meeting the standard for "easily biodegradable substances". This means that in the natural environment, XPO-4 can be rapidly decomposed by microorganisms and will not accumulate persistently in the environment, meeting the basic requirements for environmentally friendly surfactants internationally.

In terms of toxicity indicators, the acute oral toxicity LD₅₀ of XPO-4 is greater than 5000 mg/kg (rat) , indicating low acute toxicity and low risk to human health. Its fish acute toxicity EC₅₀ is greater than 100 mg/L, indicating relatively mild acute toxicity to aquatic organisms. However, according to GHS classification, this product is classified as acute aquatic toxicity category 3 (H402) , meaning it still poses certain hazards to aquatic organisms. Therefore, during use, discharge should be strictly controlled, and untreated waste liquid must not be discharged into natural water bodies.

In addition, the heavy metal content (≤10 mg/kg) and arsenic content (≤2 mg/kg) of XPO-4 are at low levels, and it does not contain harmful free phosphoric acid. Its flash point is greater than 150°C, and it is neither explosive nor oxidizing. Overall, it is controllable in terms of safety and environmental protection, making it suitable for modern textile dyeing and finishing enterprises with high environmental requirements.

Technical Parameters (Environmental Indicators)

Application Suggestions

The environmental performance of XPO-4 makes it particularly suitable for the following scenarios:

• Export order processing: For dyeing and printing enterprises that need to meet international environmental textile standards such as EU REACH regulations and OEKO-TEX® Standard 100, the high biodegradability and low toxicity of XPO-4 help improve product environmental compliance.
• Green factory construction: This product contains no heavy metals, no free phosphoric acid, and is easily biodegradable, making it a preferred auxiliary for dyeing and printing enterprises to build a green supply chain and promote cleaner production.
• Wastewater treatment coordination: Although XPO-4 itself is easily degradable, it is still recommended that enterprises conduct centralized treatment of dyeing wastewater before discharge, further degrading residual surfactants through biochemical treatment processes such as the activated sludge method to ensure effluent water quality meets standards.

Precautions

• No direct discharge into water bodies: Although XPO-4 is biodegradable, it is still classified as a substance harmful to aquatic organisms (H402). Wastewater containing this product must not be directly discharged into rivers, lakes, or public drainage systems without treatment.
• Obtaining test reports: There is no complete test report file in the database. To obtain formal SGS test reports, biodegradation test reports, RoHS/REACH compliance statements, or MSDS documents, please contact the sales or technical department of Hai'an Guoli Chemical Co., Ltd. directly . They can provide corresponding batch third-party test reports and relevant certification documents based on customer needs.
• Information timeliness: The above data are from Guoli Chemical's product database. Test values for specific batches may vary within reasonable ranges; please refer to the batch test report provided with the product.
