Tween T-85 (Polyoxyethylene (20) sorbitan trioleate) is not classified as a hazardous substance under GHS. According to EU Regulation EC 1272/2008, this product has no pictograms, no signal word, and no hazard statements, making it a non-ionic surfactant with high safety. Its flash point is > 149 °C (closed cup), and it is a non-flammable liquid, posing no risk of combustion or explosion under normal use conditions.
In terms of human health, the main potential impact of Tween T-85 is possible mild eye irritation. Prolonged or repeated skin contact may cause mild discomfort in some sensitive individuals. This product is not classified as a skin corrosive/irritant, respiratory sensitizer, carcinogen, or reproductive toxicant. Nevertheless, it is recommended to wear chemical safety goggles during handling, avoid direct contact with eyes and prolonged skin contact, and wash hands thoroughly after handling.
In terms of the environment, Tween T-85, as a polyoxyethylene non-ionic surfactant, has a certain degree of biodegradability and can be gradually decomposed by microorganisms in the natural environment. However, it should be noted that its degradation rate and extent are affected by environmental conditions, and large untreated discharges may still have short-term impacts on aquatic ecosystems (e.g., altering water surface tension, affecting dissolved oxygen, etc.). Therefore, the safety instructions explicitly require: Do not discharge directly into the environment. Waste should be disposed of by recycling or incineration through qualified institutions, and local and national environmental regulations should be followed.

Given the low toxicity of Tween T-85, it is widely used in food processing, cosmetics, and personal care products in direct contact with the human body, and is approved as a food additive (E436) both domestically and internationally. When used in pesticide formulations and industrial fields, there is also no need for excessive concern about health risks, but standard operating procedures should still be followed.
