4. What is a narrow range ethoxylate?
A narrow range ethoxylate has an EO distribution curve that is narrower than the
equivalent standard alcohol ethoxylate with a considerably lower content of
unreacted alcohol and lower foam than standard ethoxylates

5. Narrow range alcohol ethoxylates
For a standard alcohol ethoxylate with 4-5 EO:
Ø Only about half of the product contributes to the cleaning.
Ø Unreacted alcohol acts like a “greasy” soil.
Ø Higher ethoxylates are less active as degreasers. The higher cloud point
means that cleaning at a low temperature is a challenge and they can also
give foaming problems.
For a narrow range alcohol ethoxylate with 4-5 EO:
Ø Most of the product is centered at the exact EO level required for effective
cleaning.
Ø Very little unreacted alcohol thus almost no “greasy” soil in the product.
Ø Low levels of higher ethoxylates mean lower foaming and less need for
defoamers.
