According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), the main health hazard of this product is concentrated on direct contact irritation. It is not classified as a highly toxic or carcinogenic substance, and its long history of use in cosmetics and personal care products indicates that it is safe as a mild nonionic surfactant in formulations. However, strict protection is required when directly contacting the pure substance or high-concentration solutions.
Specific classification: Skin corrosion/irritation (Category 2, H315 Causes skin irritation); Serious eye damage/eye irritation (Category 2A, H319 Causes serious eye irritation). This means that if improperly handled, the stock solution splashed on the skin may cause erythema or discomfort, and splashed into the eyes may cause obvious stinging and conjunctival damage.
Inhalation risk is relatively low because the product is a viscous liquid at room temperature with low vapor pressure; however, when heated to decompose or forming aerosols/mists, inhalation may cause respiratory discomfort. Ingestion can cause gastrointestinal irritation, do not induce vomiting.
G-18 glycerol polyoxyethylene ether (polyoxyethyl glycerol ether) is mainly eliminated in the environment through biodegradation. Its molecular main chain is a carbon-oxygen structure and does not have obvious bioaccumulation. However, as a surfactant, if a large amount is discharged into water bodies in a short time, it will reduce the surface tension of water, affect the respiration and osmotic regulation of aquatic organisms, and exert pressure on the ecological balance of aquatic microbial communities.
The product database clearly requires: In case of leakage, use inert absorbent materials (such as sand and soil) to absorb and collect, dispose of as hazardous waste, and prohibit discharge into drainage systems, water bodies, or soil. This indicates that although the environmental toxicity of a single product is not high, it is still necessary to control its pathway into the environment to avoid cumulative effects and aquatic ecological risks caused by excessive local concentrations.
Subject to management regulations, enterprises using this product need to pretreat wastewater containing this component to ensure that the surfactant concentration limits required by local environmental protection departments are met before discharge.
