The present invention generally relates to premix compositions having low to zero VOCs (volatile organic compounds) according to EPA test methods which are thermally stable, free from hazardous air pollutants, alkylphenol free, dispersible in cold water and can be formulated into acid or alkaline systems. The premix of the present invention formulates into a rapid degreasing formulation when combined with typical additives used in detergent formulations. The premix composition of the invention comprises at least one nonionic surfactant, at least one cationic surfactant, an effective amount a polyhydric alcohol, and optionally water. The formulations of the present invention can be used in the preparation of aqueous or semi-aqueous detergents formulations for household, institutional and industrial applications with low or zero VOCs.

L'invention concerne en général des compositions de prémélange à teneur en composés organiques volatils (VOC) faible à nulle, selon des méthodes d'essais réalisées par l'agence pour la protection de l'environnement (EPA), qui sont thermiquement stables, dénuées de matières polluantes atmosphériques dangereuses et d'alkylphénol, dispersibles dans de l'eau froide et qui peuvent être élaborées sous forme de systèmes acides ou alcalins. Le prémélange de l'invention est élaboré sous forme de formulation de dégraissage rapide lorsqu'il est combiné à des additifs classiques utilisés dans des formulations de détergents. La composition de prémélange de l'invention comprend au moins un tensioactif non ionique, au moins un tensioactif cationique, une quantité efficace d'un polyol, et éventuellement de l'eau. Les formulations de l'invention peuvent s'avérer utiles dans la préparation de formulations de détergents aqueuses ou semi-aqueuses à teneur en VOC faible à nulle, pour des applications domestiques, collectives et industrielles,
