Abstract: A process for decreasing the build-up of inorganic incrustations on textiles deriving from water hardness and due to repeated washing cycles with detergent compositions comprises the addition to the washing bath of a non-reducing carbohydrate and/or non-reducing carbohydrate derivative as co-builder.

Abstract: A process for the disposal of chlorinated organic products, wherein said products are first treated with a sulphonating or nitrating agent, and then are oxidized with an aqueous solution of H.sub.2 O.sub.2, in the presence of Fe(II) ions as catalysts, optionally in association with ions of other transition metals selected from Cu(II), Ti(IV), Mn(II), Co(II), Ni(II), W(IV), Mo(IV), or mixtures thereof. The process leads to a substantially complete elimination of the chlorinated organic products with consequent, considerable reduction of the Chemical Oxygen Demand (COD), and to a high mineralization degree of the organic chlorine atoms.

Abstract: A process for increasing the bleaching efficiency of an inorganic persalt or hydrogen peroxide by adding to said persalt or H.sub.2 O.sub.2 an activating agent. The activating agent is an acetylated gluconic acid derivative, such as N-methyl-N-acetyl pentaacetyl gluconamide, N-methyl-N-acetyl pentaacetyl gluconamide or tetraacetyl gluconolactone. The invention also relates to the acetylated gluconic acid derivatives themselves.

Abstract: The invention relates to a process for increasing the bleaching efficiency of an inorganic persalt and to bleaching and/or detergent compositions suitable for removing stains from textiles or from other products such as paper, cellulose, cork, hair etc. These bleaching and/or detergent and/or anti-incrusting compositions comprise an inorganic persalt and an activating agent comprising an acetylated mixture of sorbitol and mannitol wherein the molar ratio between the bleaching activator and the persalt is usually from 10:90 to 50:50. The bleaching activator having an acetylation degree ranging from 1 to 6 and the weight ratio of sorbitol to mannitol in the mixture is within the range of from 2.5:1 to 4:1.

Abstract: Described is a process for increasing the bleaching efficiency of an inorganic persalt (peroxide) by adding to said persalt (peroxide) an activating agent comprising acetylated sucrose, the average acetylation degree of said acetylated sucrose being from 4.5 to 7.0.

Abstract: Process for oxidizing aromatic and aliphatic compounds, by using, in aqueous solution, an enzymatic system constituted by hydrogen, peroxide as the oxidizer compound, peroxidase and activated oxygen, or an enzyme which releases activated oxygen from H.sub.2 O.sub.2.In the preferred process, the enzymatic system is a double-enzyme one, in which peroxidase and catalase are used as enzymes.
