Boosting degreasing performance of NI the choice of cosurfactants is critical
5 Surface Chemistry EMEIA - Cleaning
Cosurfactants used in combination with non-ionics and other classes of surfactants boost
the cleaning performance.
Normal hydrotropes, as SCS and SXS, do not improve cleaning performance of non-ionics,
they only increase the cloud point and can have an impact on viscosity.
The choice of cosurfactant is critical and is driven by the right combination between product
and application.
A cosurfactant provides
6 Surface Chemistry EMEIA - Cleaning
High synergy among components of the formulation
• Active contribution to cleaning
• Perfomance at high dilution
• Less chemicals
Boosting of the cleaning performance
• Fast dirt penetraton
• Residue-free cleaning
• Dispersion capacity
• Better wetting
• Fast drying
• Low/high foam
Hydrotrope effect
• More effective than classical hydrotropes

Effective cosurfactants are products which have intrinsic properties, designed to
boost the cleaning performance of primary surfactant systems.
Many of classical hydrotropes do not have intrinsic cleaning properties.
