Choice of hydrotrope for liquid cleanersHydrotropes are organic compounds that increase the solubility of a surfactant in a formulation. Traditional hydrotropes, such as sodium cumene sulfonate, bring no additional value to the cleaning process.

Multifunctional hydrotropes are cosurfactants that bring additional value to formulations in synergy with the primary surfactant. High performance at low concentration, foam control, tolerance to alkali and electrolytes, minimal impact on the environment and low human and aquatic toxicity are examples of such additional benefits.

Hydrotropic effectThe requisite amount of hydrotrope depends on the amount and cloud point of the nonionic, but also on the amount and type of builders.

Ampholak YJH-40 and AG 6202 give low foam when combined with a low foaming nonionic surfactant. If extremely low foam is required, Berol 840 can be used in the formulation instead of Berol 260.
