PEG200MO (Polyethylene Glycol 200 Monooleate) is a non-ionic surfactant produced by esterifying polyethylene glycol with natural oleic acid. According to the UN GHS classification criteria, this product does not fall under hazardous chemical categories, and does not require hazard pictograms or signal words for labeling. Under normal conditions of use, it poses no significant harm to human health or the environment.
From a toxicological perspective, the acute oral toxicity LD₅₀ (rat) of PEG200MO is greater than 5000 mg\/kg, placing it in the low toxicity range; its acute dermal toxicity is also low. Based on its natural fatty acid origin, this product has low irritation to skin and mucous membranes, with no evidence of sensitization. Contact with skin or eyes may only cause mild, reversible irritation and does not represent a serious health hazard.
In terms of the environment, this product is based on natural renewable raw materials (natural oleic acid and polyethylene glycol) and exhibits good biodegradability. However, during handling and disposal, direct release into drainage systems, waterways, or confined spaces should be avoided. Spills should be collected using inert absorbent materials and disposed of as chemical waste in accordance with regulations, and must not be directly discharged into the environment.

PEG200MO is widely used in cosmetics and personal care products (creams, lotions, makeup removers, body washes, etc.), textile auxiliaries, metalworking fluids, and pesticide formulations. Due to its mild and low-irritation characteristics, it is particularly suitable for personal care formulations that come into direct contact with the human body. In industrial applications, its excellent chemical stability ensures reliable performance across a wide pH range and under different water quality conditions.
