  • Builder or “cobuilder” means any constituent which improves the performance of surfactants of a detergent composition.
  • tripolyphosphates have been the most frequently used in detergent compositions and detergents. However, they are partly responsible for the eutrophication of the lakes and waters slow flow when not sufficiently eliminated by treatment plants waters ; so we are looking to replace them partially or completely.
  • Copolymers of acrylic acid and maleic anhydride have been proposed (EP 25,551) as incrustation inhibitors. They have the disadvantage of not being biodegradable in a natural environment.
  • agent title "builder” or “cobuilder” for detergent composition a new range of compounds, peptide polymers and more specifically polymers or amino acid copolymers.
  • sodium polyaspartates and polyglutamates which are useful for their high biodegradability, testify to a good builder or co-builder activity (US 4,428,749). It has been shown to be the negatively charged form of these compounds which is the active form in the detergent formulation.
  • polyimides have the advantage of being stable in detergent formulations for extended durations.
  • the object of the present invention is precisely to optimize the character biodegradable from this type of compound.
  • a particular formulation has been developed according to the invention of it, such that it simultaneously satisfies the following two imperatives: it remains stable in the detergent formulation and in a humid environment it brought into contact with an aqueous medium of non-alkaline pH in at least one species water-soluble biodegradable and naturally endowed with an activity within the detergent formulation. Optimization of the biodegradable character is not acquired for costs of stability in detergent formulation nor of the subsequent generation of the active species.
  • non-alkaline pH is meant in the context of the present invention, a pH unfavorable to the hydrolysis of the polyimide to its water-soluble salts.
  • a pH unfavorable to the hydrolysis of the polyimide to its water-soluble salts are notably covered by this definition the pH of natural aqueous media, such as river water which have values close to neutrality.
  • the subject of the present invention is a "builder” or “cobuilder” preformulation for a detergent composition
  • a detergent composition comprising at least one polyimide polymer mixed with at least one silicate, characterized in that it is capable of generating at least one polypeptide species water-soluble biodegradable when it comes into contact with an aqueous medium of non-alkaline pH and in that the polyimide and the silicate are present therein in a weight ratio polyimide / silicate varying between approximately 40/60 and 55/45.
  • polyimide polymer is meant according to the invention a polyimide biopolymer whose charge density COO - is likely to increase in the detergent bath.
  • polymers can be homopolymers derived from racide as well aspartic or glutamic, as copolymers derived from aspartic racide and glutamic acid in any proportions, or copolymers derived from the acid aspartic and / or glutamic and other amino acids (for example up to 15% in weight, preferably less than 5% by weight, of other amino acids).

  • polyimides derived from aspartic or glutamic acid can be prepared by thermocondensation of said amino acid (s) in a substantially anhydrous medium, as described in JACS, 80 , 3361 (1958), J. Med. Chem. 16 , 893 (1973), Polymer 23 , 1237 (1982) or in U.S. Patent No. 3,052,655.
  • Said polyimides preferably have a COO charge density - zero; however, they can be partially hydrolyzed (by opening a few imide rings with the formation of alkali or ammonium carboxylates).
  • alkali metal silicates can be used general those already used as adjuvants in detergency formulation.
  • the most advantageous silicates in this application are those having a SiO 2 / M 2 O molar ratio of between 1.6 and 3.5. They are sold either in the form of concentrated solutions at around 30-60% by weight of dry extract, or in the form of silicate powder, atomized and optionally compacted.
  • said silicate has a SiO 2 / M 2 O molar ratio of the order of 1.6 to 3.5 and more particularly of the order of 1.8 to 2.6.
  • Said silicate can be mixed with the polyimide polymer in a form any, structured (powder, granules ...) or not.

  • the contacting operation can be carried out by simple addition, or else by spraying said concentrated solution of silicate onto the polyimide throughout known mixer with high shear, in particular of the LODIGE® type, or in the tools for granulation (drum, plate ...), at a temperature of around 20 ° C.
  • the particles of the mixture obtained can be ground, if desired, so as to obtain an average diameter of the order of 200 to 800 micrometers.
