Nonionic Surfactants

DE-4 Nonionic Wetting & Penetrating Agent

DE-4 is a high-purity nonionic surfactant used as a wetting and penetrating agent. Per the client's store it is a high-purity DE-4 nonionic wetting/penetrating agent for textile pre-treatment and industrial cleaning, with 99% purity under the JIENUO brand. As a nonionic penetrant it reduces surface tension to drive rapid wetting and capillary penetration of fibres and substrates, supporting even uptake of auxiliaries in textile pre-treatment (desizing, scouring, bleaching) and fast wetting in industrial cleaners. Nonionic character gives good compatibility with anionic and cationic systems across a wide temperature and hardness range.

Frequently asked questions

What is DE-4 best at compared with a general penetrant?

DE-4 is specified as a high-purity nonionic wetting and penetrating agent, listed at 99% under JIENUO. Its primary fit is textile pre-treatment — desizing, scouring and bleaching penetration — where the job is to drive rapid wetting and capillary penetration of the fibre so auxiliaries take up evenly. The same nonionic profile also makes it useful in leather processing and paper wetting, and in industrial cleaners that need fast surface wetting.

Which process numbers should I ask for before specifying DE-4?

Published attributes are: nonionic surfactant, 99% purity, JIENUO brand, for textile and industrial cleaning. The exact active matter, pH and cloud point are confirmed against a client COA and are not yet in the public spec — request the TDS and we will send the confirmed values for your grade. Because DE-4 is nonionic, it is broadly compatible across a wide temperature and water-hardness range, which is usually why formulators pick it over a charged alternative.

How do I validate DE-4 in my pre-treatment bath?

We can send a free 500–1000 g sample (freight to buyer, deductible from bulk). For pre-treatment we recommend a small penetration test at your working concentration and temperature — measure how fast the fabric wets versus your current penetrant, then check evenness after desizing or scouring. MOQ and lead time are quoted on request.
