Impact on Human Health: According to the safety information in the Guoli Chemical Product Database, Polyether L-35 is a non-hazardous chemical, non-flammable and non-explosive, making it very safe to use under routine industrial operating conditions. Its acute oral toxicity is extremely low (LD50 (rat) > 5 g/kg), it is non-irritating to the skin, and only very slightly irritating to the eyes. This means that under normal handling operations, as long as basic chemical handling protocols are followed, the risk to human health is very low. Nevertheless, it is still recommended to avoid direct eye contact, wash hands after handling, and use in a well-ventilated area.
Impact on the Environment: Polyether L-35 is a nonionic surfactant formed by block copolymerization of ethylene oxide and propylene oxide. Due to their good biodegradability, such surfactants are generally considered relatively environmentally friendly. However, specific ecotoxicity data (e.g., toxicity to aquatic organisms), bioaccumulation potential, and the time required for complete degradation are not currently recorded in detail in the Guoli Chemical product database. Users should strictly comply with local environmental regulations when conducting large-scale discharges or waste disposal and must not discharge directly into water bodies or soil.
Leak and Waste Disposal: In the event of a spill, use inert absorbent materials (such as sand, vermiculite) to contain and collect the spill, place it in a sealed container, and dispose of it in accordance with local regulations, then flush the spill area with plenty of water. Empty containers or residues should be treated as industrial waste and must not be discarded arbitrarily or used for holding food or drinking water.
The following are key safety and physicochemical parameters for Polyether L-35 (data source: Guoli Chemical Product Database), which help to fully understand its chemical properties and potential risks.
| Parameter Item | Value / Description |
|---|---|
| Hazard Classification | Non-hazardous Chemical |
| Acute Oral Toxicity (LD50, Rat) | > 5 g/kg (Extremely Low Toxicity) |
| Skin Irritation | Non-irritating |
| Eye Irritation | Very Slight Irritation |
| Appearance | Colorless to Light Yellow Transparent Liquid |
| Flash Point | > 100℃ (Non-flammable) |
| Chemical Stability | Stable; Avoid Contact with Strong Oxidizers |
| Heavy Metals (as Pb) | ≤ 10 mg/kg (Very Low Content) |
| Arsenic (As) | ≤ 2 mg/kg (Very Low Content) |
Due to its high safety, low-foaming wetting, and excellent emulsifying properties, Polyether L-35 is widely used in fields with high requirements for personnel contact and environmental residues. For example, in household cleaning agents, its low toxicity ensures safe use; in textile printing and dyeing and agrochemical formulations, its good spreadability and dispersibility can improve the utilization rate of active ingredients and reduce chemical consumption. When using, it is recommended to maximize its overall performance through formulation optimization while controlling emissions at the source.
