Water based cleaning products are continuouslyevolving driven by several factors

increased performance and safety demands fromconsumerschallenging regulatory requirementscost

Multifunctional surfactants bring additional value tocleaning products

Multifunctional surfactants


Basic formulation structure andfunctions

To formulate an effective water based degreaser containing nonionicsurfactants, chelating agents and other electrolytes, a hydrotrope isoften required.

What are you looking for in analcohol 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 rangeethoxylate?

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


Narrow range alcoholethoxylatesFor a narrow range alcohol ethoxylate with 4-5 EO:

Most of the product is centered at the exact EOlevel required for effective cleaning.

Very little unreacted alcohol thus almost no“greasy” soil in the product.

Low levels of higher ethoxylates mean lowerfoaming and less need for defoamers.


Key features of NRE

Berol 260Excellent fatty soil removal in water based cleaning productsespecially when it is combined with performance boosting co-surfactants

Berol 266

Two cloud points in water, effective cleaning at high and lowtemperatureCleaning products often contain two Narrow range ethoxylateswith different cloud points, Berol 266 can often replace bothcost effectively

Berol 840Low foaming nonionic surfactant with defoaming properties onprotein foam

Ethylan 1003Excellent emulsifying and wetting propertiesHydrophobic surfactant for cold degreasingLow foaming surfactant with defoaming propertiesVery good aquatic toxicity

Ethylan 1005Excellent wetting and fatty soil removal in water basedcleaning productsLow foaming nonionicVery good aquatic toxicity


Where to use NRE

Household cleaning – floor, kitchen,bathroom

Institutional cleaning – hospitality,health care, restaurants

Industrial cleaning – metaldegreasing, engine oil, car wash

Water-based multi-purpose hardsurface cleaning


Hydrotropes

Compounds that increase the solubility of a surfactant in a formulation

Referred to as “multifunctional hydrotropes” or “cosurfactants” when theyprovide additional value to formulations in synergy with the primary surfactant

ThickeningThickening is the increase of viscosity of aliquid solution

Used for Cleaning products:

to increase contact time on inclined andvertical surfacefor easier dosagefor easier application to the surfacefor increased safety


Cationic surfactantsIn concentrated solutions, have a tendency to form rod micelles resulting in a veryhigh viscosity.

Viscosity increase is due to chaotic worm like arrangement of molecules insolution. The longer the chain length of the hydrophobe, the higher the viscosity.

The use of desolubilizer reduces the amount of cationic required.


Cationic surfactants

In addition to being very stable across the whole pH range, cationicsurfactant thickeners can also contribute to cleaning, foaming,solubilisation and stability of the formula.
