Polyethylene-polypropylene glycol CAS#9003-11-6

Basic Information

Polyethylene-polypropylene glycol
Poloxamer
PPG-PEG

Polyethylene-polypropylene glycol, or poloxamer, is a block copolymer with a hydrophobic polypropylene-oxide core and hydrophilic polyethylene-oxide chains. Adjusting the block ratio tunes solubility, foaming, wetting and emulsification behavior. It is used as an emulsifier, dispersant, solubilizer, defoamer and wetting agent in pharmaceutical, cosmetic, papermaking and cleaning formulations. Additional applications include contact-lens solutions, oral or topical products, low-foam detergents, metalworking lubricants, rubber vulcanization and cell-culture media.

product description

Multifunctional Surfactant Performance:PPG-PEG (Poloxamer) acts as an emulsifier, dispersant, solubilizer, defoamer, and wetting agent, making it highly versatile for many formulations.


Highly Tunable Properties:By adjusting the ratio of polyethylene oxide (PEO) and polypropylene oxide (PPO), its solubility, foaming, and wetting behavior can be precisely customized for different applications.


Broad Industry Applicability:It is widely used in pharmaceuticals, cosmetics, papermaking, and cleaning products, demonstrating excellent cross-industry adaptability.

Excellent compatibility in formulations:Its block copolymer structure provides balanced hydrophilic and hydrophobic interactions, ensuring stable and effective performance in complex systems.



Product Description of Polyethylene-polypropylene glycol CAS#9003-11-6

Polyethylene-polypropylene glycol (PPG-PEG), also known as Poloxamer, is a versatile block copolymer surfactant. It consists of a hydrophobic PPO core with hydrophilic PEO chains on both sides. It is commonly used as an emulsifier, dispersant, solubilizer, defoamer and wetting agent in multiple industries. It is widely applied in pharmaceuticals, cosmetics, papermaking and cleaning supplies, including drug delivery systems, contact lens solutions and laxatives. Its solubility, foaming property and wetting performance can be adjusted by modifying the ratio of PEO to PPO.


Product Application of Polyethylene-polypropylene glycol CAS#9003-11-6

Pharmaceuticals: Used as an excipient in oral, topical and injectable medicines. It acts as a solubilizer for sparingly water-soluble drugs, and is also used in laxatives as a stool softener as well as in eye drop preparations. Personal Care: Applied in shampoos, toothpaste, moisturizers and contact lens care solutions as a cleansing and thickening agent. Industrial Uses: Applied as a low-foam detergent and defoamer in paper and fermentation industries, and used as a lubricant in metalworking and rubber vulcanization. Biotechnology: Used in cell culture media to protect cells from shear stress in bioreactors.
