What are you looking for in an alcohol ethoxylate?

• Highly targeted performance

• Effective at very low concentrations

• Low residual free alcohol

• Better low temperature handling

• Low foam profile

• Wide range of applications


What is a narrow range ethoxylate?

A narrow range ethoxylate has an EO distribution curve that is narrower than theequivalent standard alcohol ethoxylate with a considerably lower content ofunreacted alcohol and lower foam than standard ethoxylates


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 alsogive 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.
