Abstract (en)
[origin: EP0355626A1] A washing powder in tablet-form, containing phosphate-free or low-phosphate builder salts, anionic tensides and non-ionic tensides, is produced by first preparing two powdery to granular components (A) and (B) separately and by then mixing and compressing them. Component (A) contains the total mass of the anionic tensides while component (B) contains 75 to 100 weight percent of the total mass of the non-ionic tensides.
Abstract (fr)
On prépare un produit à lessive en tablettes, contenant des sels adjuvants de lavage exempts de phosphates ou pauvres en phosphates, des tensio-actifs anioniques et des tensio-actifs non ioniques, en préparant tout d'abord séparément deux constituants (A) et (B) pulvérulents à granuleux, que l'on mélange et que l'on comprime ensuite. Le constituant (A) contient la masse totale des tensio-actifs anioniques et le constituant (B) contient entre 75 et 100 % en poids de la masse totale des tensio-actifs non ioniques.
