    Colonial CNDF is also known as Meroxapol 311 and is, technically an ethylene oxide/propylene oxide block polymer termed peg/ppg-21/7 copolymer.

    Surfadone LP-100 is N-Octyl-2-Pyrrolidone. I doubt there is an altenative

    I don’t think you will find that Plurafac SLF18 is a Surfadone LP100 equivalent.

    Plurafac is a name give to BASF alcohol ethoxylates - which doesn’t fit with the identity of Surfadone LP100 which is N-Octyl-2-Pyrrolidone, as I stated previously.

    Colonial CNDF is equivalent to Meroxapol 311 which identifies as peg/ppg-21/7 copolymer - a POE/PPG block polymer detergent for which the commercial term by BASF is Pluronic (not Plurafac).

    You may be able to find an equivalent Pluronic material in the BASF listings.

    I’m fairly sure that this EXACT grade is not essential to your needs and a substitute PEG/PPG block polymer or even a completely different nonionic surfactant could be made.

    What is the product under consideration?

    the product will be  rince aid liquid for auto dishwash.

    I am sure that exact replacements for the two surfactants are not necessary.

    The requirement for auto dish wash rinse aids is that they contain a suitable acid material to neutralise and residues of the strongly alkaline cleaning  detergent and a compatible, very low foaming surfactant to prevent streaking.

    Some ingredient disclosures for modern rinse aids are given here in this article:
