This invention presents a detergent pastille comprising at least 50 percent by weight of a non phosphate shaper and from 0 up to 20 percent by weight of a phosphate shaper, having incorporated therein a binding substance from 0.3 up to 5 percent by weight of a neutralized polymer of hydrophilic or hydrophobic monomers having a glass transition temperature (Tg) from 40 up to 120 degree C, the monomers of which comprise (meth)acrylic acid, maleic anhydride, hydroxyalkyl(meth)acrylic acids, alkyl (meth)acrylates, alkylhydroxy (meth)acrylates, alkyl or styrene(meth)acrylic acids, polymer has a molecular weight from 10,000 up to 120,000. Pastille has improved physical properties compared to those of background art. Se presenta una pastilla de detergente que comprende al menos un 50% por peso de un formador no fosfato y desde 0 hasta 20% por peso de un formador fosfato, que tiene incorporada en la misma una sustancia aglutinante desde 0.3 hasta 5% por peso de un polímero neutralizado de monomeros hidrofílicos o hidrofobicos que tienen una temperatura de transicion de vidrio (Tg) desde 40 hasta 120 degree C, cuyos monomeros comprenden ácido (meta)acrílico, anhídrido maleico, ácidos (meta)acrílico hidroxialquilo, (meta)acrilatos alquilo, (meta)acrilatos alquilhidroxi, ácidos (meta)acrílico alquilo o estireno, el polímero tiene un peso molecular desde 10,000 hasta 120,000. La pastilla tiene propiedades físicas mejoradas en comparacion con aquellas de la técnica anterior.
