Low Toxicity and Safety
Mainstream P-series (propylene glycol ether ester) products completely avoid the significant reproductive toxicity associated with traditional E-series (ethylene glycol ether ester) solvents; classified as low-toxicity solvents, they drastically reduce health risks to humans and the environment.
High Biodegradability
Products such as ethylene glycol butyl ether acetate exhibit a BOD₅/COD ratio of approximately 0.5, making them readily biodegradable; they decompose rapidly in the natural environment without causing long-term residual accumulation or pollution.
Strong Environmental Compatibility
With low vapor pressure, these solvents do not easily migrate over long distances in the atmosphere and do not deplete the ozone layer; furthermore, they exhibit low toxicity to aquatic life-with a 96-hour fish LC₅₀ exceeding 100 mg/L-resulting in minimal impact on aquatic ecosystems.
Emission and Carbon Reduction
Certain alcohol ether ester varieties contain oxygen that aids combustion, ensuring complete burning; the primary byproducts are H₂O and CO₂, and nitrogen oxide emissions are far lower than those of traditional petrochemical solvents, aligning with green production requirements under "dual carbon" goals.
