Polyethylene Oxide 300000 CAS 25322-68-3 Thickener for Liquid Detergent Formulation
Polyethylene Oxide 300000 (PEO 300k, CAS 25322-68-3) is linear nonionic polyether polymer powder. Its long molecular chains form hydrated network in aqueous solution to provide stable thickening effect. When applied in liquid detergents, it optimizes rheological property, prevents active ingredients and abrasive particles from settling, and brings smooth texture. With excellent compatibility with anionic, nonionic surfactants, it is a multifunctional thickening additive for water-based cleaning
Product Overview
Polyethylene Oxide MW 300,000 (CAS 25322-68-3) is tailor-made medium molecular weight PEO developed for liquid detergent and household cleaning industry. Low molecular weight PEO cannot achieve satisfying thickening performance, while ultra-high molecular weight PEO tends to produce stringy, undesirable texture. This 300k grade supplies balanced thickening power without excessive stringiness. It maintains stable viscosity under wide temperature range, improves suspension performance of detergent formulations and avoids phase separation during long-term storage.
Key Features
- Molecular Weight: 300,000, CAS 25322-68-3, white free-flowing powder
- Excellent water solubility, easy to prepare transparent aqueous thickening solution
- Efficient thickening and rheology adjusting performance in cleaning formulas
- Improve suspension stability of particles, prevent sedimentation and stratification
- Good compatibility with anionic, nonionic and amphoteric surfactants
- Stable viscosity within common storage temperature range
- Less impact on detergency performance of surfactant systems
Main Applications
- Thickener for liquid laundry detergent, concentrated detergent
- Rheology modifier for dishwashing liquid and hand soap
- Suspending and thickening additive for abrasive cleaning agents
- Texture improver for various household and industrial water-based cleaners
Usage Guidance
Slowly disperse PEO powder into continuously stirred deionized water to avoid agglomeration, stir until fully dissolved, then mix with other detergent raw materials. Usual dosage: 0.1% ~0.6% of total formula weight. Adjust dosage according to target viscosity requirement. Complete stability aging test to verify thickening persistence before mass production.
Storage & Package
Seal packages tightly. Store in cool, dry and ventilated warehouse, prevent moisture absorption and direct sunlight. Standard package: 25kg kraft paper bag with inner PE liner. Shelf life: 12 months under proper storage.
Service Support
Test samples available for formula research. Stable bulk supply. We provide technical support for liquid detergent formulation. Welcome to inquire TDS, COA and factory quotation.
