Quick T-70B (dioctyl sodium sulfosuccinate, CAS: 577-11-7) is a classic anionic surfactant. It has been commercially available under the trade names Aerosol OT or DOSS for decades internationally and is a well-studied and mature chemical product. According to Guoli Chemical's product database, this product has complete safety data (GHS classification, acute toxicity LD50 ≈ 1900 mg/kg, hazard statements H302/H315/H319/H335, etc.), but the database currently does not include specific environmental compliance documents for this product (such as biodegradability test reports, REACH registration certificates, RoHS test reports, VOC content reports, or third-party environmental certifications).
From a chemical structure perspective, dioctyl sodium sulfosuccinate is a sulfonate surfactant with branched alkyl chains (dioctyl/di(2-ethylhexyl)). Generally, the biodegradability of anionic surfactants with branched structures is usually lower than that of linear alkyl products , and the degradation rate may be relatively slow. However, specific biodegradability data (e.g., OECD 301 series test results) need to be confirmed by actual measurements provided by the manufacturer. In terms of wastewater treatment, the low-foaming properties of this product help reduce operational issues caused by foam in industrial wastewater. However, the database currently does not include ecological toxicity data for this product in environmental waters (e.g., fish acute toxicity LC50, algae inhibition EC50).
It is recommended that users who need to confirm environmental compliance directly contact Guoli Chemical's sales or technical department to request the following types of test documents: product certificate of analysis (COA), safety data sheet (SDS/MSDS, detailed safety information already available in the database), biodegradability test report, heavy metal and hazardous substance test report, and specific regulatory compliance statements (e.g., compliance with GB/T, EU REACH, US TSCA, etc.). For information on whether this product has passed specific textile industry environmental certifications such as ZHEL/OEKO-TEX, the official latest certification documents issued by Guoli Chemical shall prevail.

Quick T-70B, with its excellent rapid penetration and wetting properties, is widely used in ten major fields including textile printing and dyeing, pesticide formulations, coatings and inks, and industrial cleaning. If the end-use involves export trade, food contact materials, cosmetic formulations, or use in ecologically sensitive areas , it is strongly recommended to confirm with Guoli Chemical before purchase whether the product meets the environmental regulatory requirements of the target market (e.g., EU REACH regulations, US EPA standards, China's Environmental Management of New Chemical Substances Regulations), and to request corresponding compliance statements or third-party test reports.
