Product Description: PEG 400 (Polyethylene Glycol 400)
PEG 400, or Polyethylene Glycol 400, is a versatile, water-soluble polymer that is widely used in various industries due to its unique properties. It is a clear, colorless, and odorless liquid that is non-toxic and non-irritating, making it suitable for a wide range of applications. PEG 400 is known for its ability to dissolve both hydrophilic and lipophilic substances, which makes it an excellent solvent and carrier for active ingredients in pharmaceuticals, cosmetics, and food products. Its low viscosity and hygroscopic nature allow it to retain moisture, making it an ideal ingredient in formulations that require hydration and lubrication.
Uses of PEG 400
- Pharmaceuticals: Used as a solvent, plasticizer, and excipient in drug formulations, including oral, topical, and injectable medications.
- Cosmetics and Personal Care: Commonly found in creams, lotions, and ointments as a moisturizer and emulsifier.
- Food Industry: Acts as a food additive and humectant, helping to retain moisture in food products.
- Industrial Applications: Utilized in the manufacturing of lubricants, surfactants, and as a carrier for pesticides and herbicides.
- Research and Laboratory: Employed in various laboratory applications, including as a medium for biochemical reactions and in the preparation of samples.
