Beschreibung
Zusammenfassung:	Solid detergent compositions designed to maintain solid integrity throughout production of the pressed solid, during mechanical conveying and during ejection from molds, are disclosed. Solid detergent compositions having unexpected immediate block hardness without a curing step are provided by inclusion of a hardness additive composition comprising a synergistic ratio of polycarboxylic acid polymer chelants to aminocarboxylate chelants. Methods of making solid detergent compositions and solid detergent compositions having at least substantially similar cleaning performance to solid detergent compositions without the hardness additive composition are also provided. L'invention concerne des compositions détergentes solides conçues pour maintenir l'intégrité solide pendant la production du solide pressé, pendant le transport mécanique et pendant l'éjection à partir de moules. Des compositions détergentes solides présentant une dureté de bloc immédiate inattendue sans étape de durcissement sont obtenues par l'inclusion d'une composition d'additif de dureté comprenant un rapport synergique de chélatants de type polymère de poly(acide carboxylique) à des chélatants de type aminocarboxylate. L'invention concerne également des procédés de fabrication de compositions détergentes solides et des compositions détergentes solides présentant au moins des performances de nettoyage sensiblement similaires à celles des compositions détergentes solides sans la composition additive de dureté.
