Alkali-resistant Penetrant AEP

Alkali-resistant Penetrant AEP is an anionic isooctanol polyoxyethylene phosphate acid ester (solid content >=98%, pH <3), supplied as a colorless-to-yellowish liquid. It delivers rapid, stable penetration in strongly alkaline baths and scouring liquors where ordinary penetrants break down, and conforms to Q/320621HA070. It is primarily used in textile pretreatment, alkali-bath penetration and scouring.

Frequently asked questions

Will AEP hold up in a strongly alkaline scouring or mercerising bath?

That is exactly what AEP is built for. It is an anionic isooctanol polyoxyethylene phosphate acid ester with published solid content ≥98% and pH <3, supplied as a colourless-to-yellowish liquid. Ordinary penetrants break down in strong alkali; AEP is specified to keep penetrating in high-alkali scouring and mercerising liquors where the bath would destroy a neutral penetrant. We publish pH <3 as the product pH; we do not state a specific caustic-tolerance figure, so confirm your NaOH concentration with the TDS.

What standard and identity back AEP?

AEP conforms to the enterprise standard Q/320621HA070. Identity is double-verified: CAS 68439-39-4 appears in the client manual and the CAS reference document, and the spec block (anionic type, appearance, solid content ≥98%, pH <3) is transcribed from the manual. For incoming QC we recommend a lot-specific COA.

Where in the textile process would I use AEP?

Primary use is textile pre-treatment: cotton and blended-fabric alkali scouring, penetration in high-alkali mercerising baths, desizing and boil-off liquor wetting, and continuous or pad-batch pre-treatment. It also fits industrial alkaline cleaning systems that need a penetrant which survives the caustic. If your line is mercerising or heavy scouring, AEP is the more relevant choice than a neutral penetrant.

How do I trial AEP in my alkaline bath?

Free 500–1000 g sample (freight to buyer, deductible from bulk). Because AEP is acidic (pH <3) and goes into alkaline liquor, we suggest a small compatibility check: add it to your scouring bath at working concentration and watch for any haze or separation before scaling. Full handling and the standard are on the TDS/MSDS. MOQ, price and lead time on request.
