What safety precautions should be taken when using Peregal O-20?

Peregal O-20 is a low-toxicity nonionic surfactant, but it can cause skin, eye, and respiratory tract irritation. Protective equipment should be worn and good ventilation maintained during operation.

Detailed Description

Peregal O-20 (fatty alcohol polyoxyethylene (20) ether, CAS number: 68439-49-6), classified according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), is an irritant substance (Xi). The main hazards include: skin irritation (Category 2, H315), serious eye irritation (Category 2A, H319), and respiratory tract irritation (Category 3, H335). Risk phrases are R36/37/38, meaning irritating to eyes, respiratory system, and skin.

From a toxicological perspective, the acute oral LD50 (rat) of Peregal O-20 is greater than 2000 mg/kg, placing it in the low toxicity category, and it is relatively safe under normal industrial use conditions. However, it should be noted that this product is non-flammable and non-explosive, and under normal storage and use conditions, thermal decomposition does not produce harmful gases. Ecotoxicological data indicate that it has low toxicity to aquatic organisms, is readily biodegradable, and does not possess persistent, bioaccumulative, and toxic (PBT) or very persistent and very bioaccumulative (vPvB) properties.

Safe Handling Precautions

When handling Peregal O-20, the following precautions should be strictly observed to minimize exposure risks:

• Ventilation requirements: Avoid inhaling dust or mist (P261). Use only outdoors or in a well-ventilated area (P271) to prevent the formation and accumulation of combustible dust clouds.
• Personal protective equipment: Wear appropriate protective equipment during operation, including protective gloves, goggles, or face shield (P280).
• Hygiene practices: Thoroughly wash exposed skin immediately and thoroughly after handling (P264). Avoid contact with broken skin and mucous membranes.
• Area management: Maintain good industrial hygiene practices in the workplace. Non-operating personnel should stay away from operating areas.
