Definitions

  • the subject of the present invention is a detergent composition containing a polyimide biopolymer capable of generating by hydrolysis in a washing medium a polypeptide "builder" at least partially biodegradable and the applications in the field of detergency of said composition.
  • builder is intended to denote according to the invention, any constituent which improves the performance of surfactants of a detergent composition.
  • tripolyphosphates have been the most frequently used "builders" in detergent compositions and detergents.
  • builders for ecological imperatives, we are now looking for substitutes for them.
  • This detergent composition is characterized by the use as a constituent of a polyimide biopolymer having a charge density COO ⁇ which can range from 0 to 5 ⁇ 10 ⁇ 4 mole / g of polymer and capable of acquiring in the washing bath a COO ⁇ charge density at least equal to 10 ⁇ 3 mole / g of polymer.
  • the present invention relates more particularly to detergent compositions, one of the constituents of which is at least one polyimide biopolymer or one of its derivatives, characterized in that this constituent has a charge density COO ⁇ greater than 5. 10 ⁇ 4 mole / g and in that it is capable of increasing this charge density COO ⁇ in the detergent bath.
  • the detergent composition which is the subject of the present invention advantageously leads, by hydrolysis within the washing bath of the polyimide biopolymer, to a builder at least partially biodegradable.
  • the initial charge density COO ⁇ of the polyimide biopolymer or derivative thereof is less than or equal to 2. 10 ⁇ 3 mole / g of polymer.
  • detergent composition denotes, according to the invention, washing machine detergents, dishwasher detergents or any other washing product for household use.
  • detergent bath or “detergent medium” means the aqueous detergent solution (detergent composition) present in the washing machine during the washing cycles; the quantity of detergent present is that recommended by the manufacturer; this is generally less than 20g / liter; the pH of such a solution is greater than or equal to 9.
  • polyimide biopolymers having a charge density COO ⁇ in accordance with the present invention and which can be used, mention may be made of polyimides derived from the polycondensation of aminodiacides, in particular aspartic or glutamic acid or precursors of said aminodiacides; these polymers dissolve in water at basic pH with the formation of free COO ⁇ functions.
  • polymers can be homopolymers derived from aspartic or glutamic acid, as copolymers derived from aspartic acid and glutamic acid in any proportion, or copolymers derived from aspartic acid and / or glutamic and other amino acids (for example up to 15% by weight, preferably less than 5% by weight, other amino acids).
  • copolymerizable amino acids there may be mentioned glycine, alanine, valine, leucine, isoleucine, phenylalanine, methionine, tryptophan, histidine, proline, lysine, arginine, serine , threonine, cysteine ...
  • Said polyimide biopolymers or their derivatives can have a weight-average molecular mass of the order of 300 to 107 and generally of the order of 500 to 60,000.
  • polyimides derived from aspartic or glutamic acid can be prepared in particular 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.
  • the charge density COO ⁇ required according to the invention, can also be satisfied by using partially hydrolyzed polyimide biopolymers.
  • These compounds also designated by the term polyimide derivatives, are in particular accessible by controlled opening of at least one of the imide rings of a primary polyimide chain with formation of carboxylates.
  • the amount of polyimide biopolymer entering the detergent composition forming the subject of the invention can range from 0.2 to 80% by weight and preferably from 2 to 5% by weight of said detergent composition.
  • a surfactant in an amount which can range from 2 to 50%, preferably from 6 to 30%, by weight of said detergent composition.
  • Various constituents can also be present in the detergent composition of the invention to lead to detergents or powdered cleaning products.
  • the present invention also relates to the uses of a polyimide biopolymer as defined above, in powdered detergent compositions.
  • the detergent composition which is the subject of the invention has good efficacy, whether in primary detergency or in secondary detergency.
  • the incorporation of a polyimide which is only hydrolyzable in a detergent medium guarantees the detergent composition stability, during storage, superior to that of a composition directly containing the biodegradable polypeptide.
  • the single figure represents the variation in the level of a calcium carbonate sedimentate as a function of the polymer concentration.
  • anhydrous ammonium maleate 450g are spread on a rectangular stainless steel tray without edge on an area of approximately 95 cm2.
  • the tray is placed in a THERMOSI SR 2000 ® ventilated oven without air and preheated to 230 ° C. After two hours of reaction, the extractable rate is evaluated at 1.64% w / w.
  • a powder is recovered which is a polysuccinimide (IR spectrometry), whose number average molecular mass Mn is equal to 900 (measurement of viscosity in 0.5 N NaOH).
  • control detergent a detergent of composition above but not containing polysuccinimide.
  • This example highlights the sequestration capacity of the calcium ions of the polysuccinimide of Example 1 after in situ hydrolysis to polyaspartic acid in basic medium.
  • the sequestration capacity of calcium ions is measured using an electrode having a selective membrane permeable to calcium ions.
  • the solution obtained is called "hydrolyzate”.
  • This example demonstrates the capacity of the polysuccinimide of Example 1 to disperse calcium carbonate, after hydrolysis in situ to aspartic acid in basic medium.
  • the level of the sedimentate in cm3 is measured after 10 minutes and the curve of the sedimentate level is plotted as a function of the concentration in ppm of the polymer (expressed in sec).
  • the curve of the single figure first shows a flocculation phenomenon (too low coverage rate of the particles by the polymer) then restabilization.
  • This capacity for stabilizing mineral particles is particularly advantageous since it is known that the latter are the cause of incrustation phenomena due to deposits which accumulate on cotton.
  • This example demonstrates the capacity of the polysuccinimide of Example 1 to inhibit the crystallization of calcium carbonate, after hydrolysis in situ to polyaspartic acid in basic medium.
  • the results are as follows:
  • the mineral incrustation is calculated from the ash rate (in% relative to the total weight of the cotton) of the fabrics washed, dried and burnt at 950 ° C for 3 hours.
