Polykem AEO-7 for Cleaning and Textile Formulations: Key Indicators Buyers Should Check

AEO-7, also known as Lauryl Alcohol 7 Mole Ethoxylate or Lauryl Alcohol Ethoxylate AEO-7, is a nonionic surfactant used in cleaning, textile processing, emulsification and industrial auxiliary formulations. As a mid-EO alcohol ethoxylate, AEO-7 offers a practical balance between water dispersibility and emulsification performance, making it suitable for systems that require wetting, detergency and oil removal.

Why AEO-7 Is Used in Cleaning and Textile Systems

The reason AEO-7 shows up in both cleaning and textile formulations comes down to one thing: it helps liquids do what they're supposed to do on surfaces and fibers.

In cleaning systems — degreasers, equipment cleaners, metal part washing — the practical need is for the liquid to spread and contact the surface quickly rather than beading up. AEO-7 supports this wetting and soil removal performance, which is why it appears in formulations targeting oily residues or processing contamination on hard surfaces.

Textile processing has a slightly different ask. Here the concern is even penetration into fiber during scouring or washing, especially when the fabric still carries oils, waxes or sizing agents from earlier production steps. The same wetting mechanism that works on hard surfaces translates reasonably well to fiber penetration, which is part of why AEO-7 works across both.

For industrial auxiliary formulations where oils or solvents need to be dispersed into a system, AEO-7 also comes up — though in these cases buyers tend to check both wetting performance and emulsification stability together rather than treating them as separate requirements.

Key Indicators Buyers Should Check

For AEO-7, appearance is usually checked first. The product is generally supplied as a colorless, white or pale yellow liquid at 25°C. A uniform appearance helps buyers evaluate storage condition, product consistency and whether there are visible impurities before testing.

Color is commonly measured by Pt-Co value. AEO-7 can be controlled at a low color level, such as Pt-Co ≤20 or ≤50 depending on the specification. Lower color is preferred for detergent, textile and light-colored industrial formulations where the final product appearance matters.

Hydroxyl value is an important indicator for confirming the EO grade range. AEO-7 is typically controlled around 108–116 mg KOH/g, and some specifications may use a narrower range such as 108–114 mg KOH/g. This helps buyers confirm whether the material matches the expected AEO-7 grade and performance range.

Moisture is usually controlled at ≤0.5%. Low moisture helps support storage stability and formulation consistency, especially for concentrated cleaning agents, textile auxiliaries and industrial blends.

pH value is commonly checked in 1% aqueous solution. AEO-7 is usually near neutral, with ranges such as 5.0–7.0 or 6.0–7.0 depending on the specification. This makes it easier to combine with other surfactants, solvents, alkali builders or textile auxiliaries in many formulation systems.

Cloud point is another useful reference for nonionic surfactants. For AEO-7, the cloud point can be around 50–60°C in 1% aqueous solution. This helps buyers evaluate whether the product can maintain suitable solubility and performance under the processing temperature of cleaning, textile or industrial applications.

Why choose Polykem AEO-7

Polykem supplies AEO-7 Lauryl Alcohol Ethoxylate for customers in cleaning, textile, emulsification and industrial formulation applications. In addition to AEO-7, Polykem can also provide other AEO grades including AEO-1, AEO-2, AEO-3, AEO-4, AEO-5 and AEO-9, helping customers compare different EO ranges according to solubility, emulsification performance, wetting effect and final application requirements.

For customers testing a new formula or replacing an existing supplier, Polykem can help confirm appearance, color, hydroxyl value, moisture, pH value, cloud point and packaging requirements according to the final application.

Polykem can also supply Alkyl Polyglucoside (APG), Sodium Lauryl Ether Sulfate (SLES), Polyethylene Glycol (PEG), Polypropylene Glycol (PPG), Polyoxyethylene Sorbitan Fatty Acid Ester (TWEEN) and other surfactants and industrial chemicals. COA, TDS and SDS can be provided according to order requirements, and free samples are available for testing before bulk purchase.
