Abstract

L'invention se rapporte à des compositions d'un pH compris entre 1 et 4, permettant d'enlever des dépôts calcaires et comprenant de l'acide maléique, un agent tensioactif non ionique, un agent tensioactif anionique, un parfum et un acide alpha-hydroxy carboxylique (de préférence l'acide citrique). On pense que la combinaison acide alpha-hydroxy carboxylique et acide maléique est moins toxique et moins apte à se décomposer qu'une quantité équivalente d'acide maléique, en d'autres termes, une quantité présentant une aptitude comparable à enlever les dépôts calcaires. Cependant, l'on pense également que l'acide alpha-hydroxy carboxylique interagit avec l'agent tensioactif non ionique pour déstabiliser le produit en l'absence de l'agent tensioactif anionique. L'on suppose en conséquence qu'il se produit une interaction synergique entre les constituants, qui permet d'obtenir une composition stable et efficace contenant l'acide alpha-hydroxy carboxylique comme constituant remplaçant partiellement l'acide maléique.
