Abstract (en)

[origin: EP0863200A2] Production of a detergent bodies (e.g. tablets) containing surfactants, builders, etc. is by pressing a particulate composition comprising (by wt., based on total body) : (A) 5-20% super-dried amorphous silicate; (B) 0.5-10% polyethylene glycol; and (C) 1-15% water or an aqueous solution. Preferably (A) is amorphous silicate with delayed disintegration and (B) has mol wt. 4,000 (i.e. is PEG 4000) and is used especially at 1-4%, while (C) is especially used at 3-8%. Optionally also present as additional builders are oligo- and/or polymeric polycarboxylates (especially citrates) and/or acrylic acid/maleic acid copolymers. The total surfactant content is 5-60 (especially above 15) wt.%, with a greater amount of anionic than nonionic surfactant being used and the nonionic surfactants being alkyl polyglycosides.
