Properties and Usage:
Poloxamer 188, also known as F-68, is a highly efficient nonionic surfactant and belongs to polyoxyethylene-polyoxypropylene block copolymer.
1. Application in the pharmaceutical field
In the pharmaceutical industry, poloxamer 188 is very important in biopharmaceuticals. It can effectively reduce the aggregation of biological preparations during freezing, drying, and mechanical stress, thereby protecting proteins and cells from damage.
2. Application in cosmetics and personal care products
Poloxamer 188 is widely used in cosmetics and personal care products due to its superior skin care and emollient properties. As an emulsifier, poloxamer 188 can help the water phase and oil phase components to effectively mix to produce stable emulsions or cream products. In addition, it is also widely used in shampoo, conditioner, cream and other products to enhance the silkiness of the product and improve the moisturizing of the skin.
3. Application in the food industry
In the food industry, poloxamer 188 improves the texture and stability of food. Its excellent emulsifying properties can improve the stability of oil-water mixtures and are suitable for a variety of food products such as ice cream, sauces and milkshakes.
4. Industrial applications
Poloxamer 188 is used as a lubricant and antistatic agent in the industrial field. It helps improve material handling performance during mechanical processing in the textile and plastic industries, reduces static electricity accumulation, and improves the overall quality of products. In addition, poloxamer 188 is also used to manufacture products such as polyurethane foams, adhesives and elastomers, showing excellent versatility.
Commonly used concentrations are 3%-5% aqueous solutions
