- 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.

- the preformulation claimed may contain in addition to polyimide and silicate, an alkali metal carbonate.
- an alkali metal carbonate may contain in addition to polyimide and silicate.
- the presence of a carbonate within the preformulation is particularly advantageous in terms of humidity stability.
- the carbonate content of said preformulation varies according to the content of silicate.
- the carbonate percentages presented below will always be expressed relative to the total weight of carbonates and silicates.
- the carbonate content varies between 20% and 75%, expressed by relative to the total weight of silicates and carbonates.
- Said polyimide / silicate mixture with, if appropriate, carbonate can be prepared by bringing into contact (by adsorption and / or absorption) of a concentrated aqueous solution of an alkali metal silicate with a molar ratio SiO 2 / M 2 O of 1 '' from 1.6 to 3.5, preferably of the order of 1.8 to 2.6, and having a dry extract of the order of 30 to 60%, preferably of the order of 35 to 60%, with said polyimide polymer and, where appropriate, said carbonate, and drying.
- 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.
- the densified cogranules are then dried by any known means.
- a method particularly effective is drying in a fluidized bed using an air stream at a temperature of the order of 40 to 150 ° C, preferably 40 to 100 ° C. This operation is carried out for a period depending on the air temperature, the water content of the cogranules at the outlet of the granulation device and that desired dried cogranules, as well as fluidization conditions; the skilled person knows adapt these different conditions to the desired product.

Son comportement peut s'expliciter comme suit : lorsque cette préformulation spécifique de polymère polyimide entre en contact avec un taux d'humidité important, voire rencontre un milieu aqueux non alcalin, on assiste localement au niveau des grains à un abaissement de leur alcalinité qui induit la formation, à la surface du mélange et plus particulièrement à la surface des cogranulés, d'une couche de silice ; avantageusement, cette couche de silice en se constituant vient préserver le coeur des cogranulés contenant du polyimide et du silicate n'ayant pas réagi ; de cette manière, grâce à cette "coquille" de silice, on se réserve au niveau des polyimides une alcalinité suffisante, générée par les silicates, pour rendre possible l'hydrolyse partielle ou totale dudit polyimide en son ou ses sels hydrosolubles de polyaminoacides non contaminants pour l'environnement.
