State the alkali level and whether foam is wanted. A shampoo CMEA story does not specify a workshop degreaser.
Foam is a feature or a defect
A workshop foam cleaner and a spray degreaser want opposite foam. Alkanolamides push foam up. They belong in the first and usually not in the second. Esteem’s low-foam surfactant range is the spray alternative.
Hard-surface pages cover the wetting system. Add the amide only after the soil-removal surfactants and builders are named.
Alkali and shelf life
Amides are made by condensation and can move backward in strong, hot alkali. A sample that is fine at neutral pH can lose body after a month in caustic. Put the storage test in the brief.
Color and odor limits are looser than in shampoo and still matter if the cleaner is unscented and sold in a clear pack.
Where it fits
Acid thickeners for toilet cleaners are not alkanolamides. Keep that article separate.
If the industrial buyer still requires a residual-DEA limit, use the CDEA specification note rather than assuming industrial means unspecced.
| Cleaner | Amide? | Better tool if not |
|---|---|---|
| Foam gun / mop | Often yes | — |
| Spray washer | No | Low-foam nonionic |
| Acid toilet | Rare | Acid thickener |
| Cosmetic shampoo | Different spec | CMEA / DEA rule |
Foam is either the product or the defect
A foam gun or a mop cleaner uses foam as cling and as a signal that the floor is wet. CMEA or CDEA will support that foam next to an anionic. A spray cabinet, a CIP spray, or a pressure washer treats the same foam as a defect: it cushions the jet, overflows the sump, and rinses poorly. The amide belongs in the first group and usually not in the second.
Soil removal is still the anionic, the nonionic, the solvent, or the builder. An amide does not degrease on its own. Add it after those are named, and only if the user wants foam and body. Esteem’s low-foam and end-capped ranges are the spray alternative, not a higher amide dose.
Alkali walks the reaction backward
Amidification is a condensation. In strong caustic, especially when the cleaner is warm in storage, water and hydroxide can split the amide back toward soap and free alkanolamine. A sample that built viscosity at neutral pH can look thin after a month in a high-caustic tote. The shelf-life test has to be at the pH and temperature the warehouse actually uses.
Color and odor limits are looser than in a shampoo and still matter in an unscented cleaner sold in a clear pack. Acid cleaners are a different case again. Toilet and descaler thickeners are not alkanolamides. Keep that chemistry in its own brief.
Do not import the cosmetic file by accident
Industrial buyers usually do not need a shampoo residual-DEA limit or a mildness claim. They do need pH, foam yes-or-no, and the application method. If a particular industrial customer still writes a residual-DEA cap, use the CDEA specification note and send the number. “Industrial” does not mean unspecced, and it does not mean the cosmetic grade is required in every drum.
A workshop degreaser sampled from a shampoo CMEA story will be the wrong foam, the wrong alkali stability test, and the wrong paperwork. State alkaline, neutral, or acid, and state mop, foam gun, or spray, before the amide is chosen.
How to Specify with Esteem
- State alkaline, neutral, or acid.
- Say mop, foam gun, or spray.
- If it is a spray, question whether any amide belongs.
- Pair the amide with the anionic or nonionic that does the soil removal.
- Skip cosmetic residual-DEA language unless the product is actually cosmetic.
Hard-surface surfactant design is on hard-surface cleaners. Amides are the foam and body additive, not the builder.
