Regarding the physicochemical technical parameters of Polyether F-68, the current database only provides basic physical descriptions, and there are no detailed numerical technical parameters available at this time.

Detailed Description

Polyether F-68 (Poloxamer 188) is a block polyether nonionic surfactant. Its unique polyoxyethylene-polyoxypropylene-polyoxyethylene triblock structure endows it with excellent emulsifying, wetting, and dispersing capabilities. According to existing data, its appearance is a white to slightly yellow waxy solid, belonging to the category of nonionic surfactants, with CAS number 9003-11-6.

In terms of application characteristics, this product exhibits extremely high stability in aqueous solutions, good tolerance to acidic and alkaline environments and hard water ions, and can maintain stable interfacial activity under harsh conditions. These characteristics make it an ideal choice for high-end fields such as pharmaceuticals, biotechnology, and personal care products. However, the product database provided this time does not include common numerical physicochemical parameters such as HLB value, cloud point, hydroxyl value, melting point, density, viscosity, or critical micelle concentration.

Application Suggestions

Although some numerical parameters are missing, the application processes of Polyether F-68 in various fields are already quite mature. In biotechnology cell culture, it is used as a shear protectant at a typical concentration of 0.5 to 3 g/L. In the pharmaceutical field, it can serve as an emulsifier for intravenous injection emulsions or a solubilizer for oral formulations. In personal care products, it is used as a mild emulsifier and dispersant, with the optimal dosage typically determined through compatibility tests.

Precautions

When handling, follow the personal protective requirements in the safety data sheet and avoid generating dust. Although there are no specific physicochemical values at present, the product is classified as GHS Category 2 skin/eye irritant and may cause respiratory irritation. Ensure operation in a well-ventilated area and wear appropriate protective gloves and goggles.
