Polyether L-45 is a poloxamer-type nonionic surfactant, known for its low foam, excellent emulsifying and wetting ability, and wide pH stability. It is widely used in industrial cleaning, rinse aids, metalworking, textile auxiliaries, and other fields.
Detailed Description
Polyether L-45 (CAS: 9003-11-6) belongs to the polyether polyol class of nonionic surfactants, also known as Polyether Polyol L-45, Polyether Polyol L-45, Pluronic L-45, Poloxamer. It appears as a colorless to slightly yellow transparent liquid with excellent surface-active properties, capable of serving multiple roles in formulations such as emulsifier, wetting agent, dispersant, leveling agent, and softener.
The most prominent feature of this product is its low foam characteristic — in high-efficiency cleaning scenarios, low foam means less foam residue, faster rinsing speed, and lower water consumption. At the same time, it has excellent acid and alkali stability and hard water resistance. Even in water with high calcium and magnesium ion content or under wide pH conditions, it maintains its activity, demonstrating strong adaptability in complex industrial environments.
From a safety perspective, Polyether L-45 is a low-toxicity chemical, but it is important to note that it is irritating to skin and eyes (H315/H319). Protective gloves and goggles should be worn during operation, and it should be used in a well-ventilated environment.

Application Suggestions
Polyether L-45 has mature application solutions in multiple industrial fields:
- Industrial Cleaners: As an efficient low-foam wetting agent, it can quickly penetrate and emulsify heavy oil stains, especially suitable for spray cleaning systems of metal and hard surfaces.
- Rinse Aids: Significantly reduces the surface tension of rinse water, promoting uniform spreading and rapid detachment of water film, achieving dry dishes with no water spots or streaks.
- Metalworking Fluids: Possesses both lubrication and cooling auxiliary functions, excellent foam suppression prevents foam overflow during high-pressure spraying and high-speed cutting.
- Textile Scouring Agents and Bleaching Aids: In desizing, scouring, and bleaching processes, it efficiently removes cotton wax impurities through penetration and dispersion, and suspends dirt to prevent re-deposition.
- Pesticide Emulsifiers: Enables oily pesticide active ingredients to automatically disperse into stable emulsions with uniform particle size in water, not prone to layering or precipitation.
- Defoamer Formulations: It is low-foam by nature and can produce synergistic foam control with silicone or mineral oil, commonly used as a base carrier or synergistic component in industrial defoamers.
Precautions
- Storage temperature should be controlled between 5–35°C, avoid freezing or drastic temperature fluctuations.
- During operation, wear chemical safety goggles and butyl/nitrile rubber protective gloves, ensure good ventilation in the work environment.
- Avoid contact with incompatible substances such as strong oxidizers, strong acids, strong bases.
- In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention.
- Empty containers may retain hazardous residues, do not reuse for other purposes, dispose of through qualified agencies in accordance with local regulations.
