Definitions
- the present invention relates to the use of bactericidal zeolites containing metal ions to give hydrophilic superabsorbent polymers anti-odor properties.
- Superabsorbent polymers are used in the manufacture of diapers to improve their absorption capacity for liquids and urine in particular.
- SAP Superabsorbent polymers
- the absorbent article When the absorbent article is impregnated with urine, it develops various strong and unpleasant odors, including the smell of ammonia coming from the hydrolysis of urea by the ureases of bacteria (Proteus, Acinetobacter, etc.) on the skin and in the digestive tract.
- the invention thus consists of a superabsorbent composition intended for the production of hygiene articles of the linen, diaper and diaper type which do not develop unpleasant odors, comprising a superabsorbent polymer for water, saline solutions and body fluids. and zeolites exchanged with metal cations endowed with bactericidal properties in the proportion of 0.05% to 10%, preferably 0.1 to 5% relative to the superabsorbent composition.
- Superabsorbent polymers are products that meet the definition of superabsorbents, as found in the book "Absorbent Polymer Technology, Studies in Polymer Sciences 8, Elsevier 1990", namely, dry materials capable of soaking up spontaneously from an aqueous fluid at least twenty times its own weight.
- Superabsorbent polymers within the meaning of the present invention are polymers which result from the polymerization with partial crosslinking of monomers water-soluble ethylenically unsaturated, in particular acrylic acid and methacrylic acid, as well as their alkaline salts, whether obtained by a polymerization process in solution or in reverse suspension.
- Zeolites are microporous crystalline aluminosilicates whose structure is that of assemblies tetrahedra Si0 Al0 -and 4 "and ⁇ 3 ue 1 'on P was represented by a formula expressed as oxides
- M is an alkaline or alkaline earth cation of valence n, where x is a number less than or equal to 1, where y is between 2 and 30, and where z is a number which translates the hydration state of the zeolite.
- zeolites exchanged with certain metal cations themselves bactericidal, are known, and they have been used to prepare bactericidal fibers making it possible to manufacture articles of current consumption: socks, underwear, etc. in Japan (US 4,525,410 and 5,064,599, Kanebo).
- the Procter & Gamble Cy claimed an absorbent system controlling body odors by incorporating silver-exchanged zeolites in the perforated plastic film which envelops the absorbent (WO 95/24173).
- Others have housed a layer of such zeolites sandwiched between two sheets of superabsorbent polymer films (JP 63 156540, Dainippon Printing Co).
- Other patents describe the aqueous dispersion of silver-exchanged zeolites in textile layers (JP 63 097.159, Matsui), or have used them in impregnation of confetti dispersed in the absorbent components of hygiene articles (EP 0389015, Procter & Gamble).
- the superabsorbent compositions of the invention are very easily prepared, compositions resistant to the emission of ammonia and of unpleasant odors when they are soaked in body fluids by simple mixing of superabsorbent polymer powder with a particle size between 100 and 800 ⁇ m , with a zeolite powder exchanged with metal cations, preferably with a particle size between 0.5 and 20 ⁇ m, at a rate of 0.05 to 10% and preferably from 0.1 to 5% by weight of zeolite exchanged with compared to the composition.
- These exchanged zeolites prepare themselves in a known manner from natural or synthetic zeolites.
- zeolites A are used for this purpose.
- the zeolite powder is suspended in water with stirring, and an aqueous solution of the metal ion with bactericidal property, in particular the Ag + , Cu 2+ , Zn2 + ions, is added thereto. It is recommended to disperse the exchangeable zeolite powder, preferably at pH 7-8 to avoid precipitation of the metal oxide or hydroxide.
- the useful quantity of Ag + ions fixed in the zeolite is between 0.01 and 10% by weight, relative to the zeolite, preferably between 0.05% and 5%.
- the amount of Cu 2+ , Zn 2+ ions is between 0.1 and 25%, preferably between 0.2 and 15% by weight.
- the superabsorbent compositions of the invention gel on contact with water, aqueous saline solutions or body fluids such as the superabsorbents of the prior art, and the gels thus formed behave so substantially identical. They can therefore be used in place of ordinary superabsorbents in the manufacture of hygiene articles such as complete diapers or diapers for babies, children, adults or old men and women.
- the superabsorbent polymer used is a partially neutralized polyacrylic acid sold under the name AQUA-KEEP®D (Elf Atochem SA).
- Example 1 Preparation of zeolites exchanged with silver.
- zeolite X 100 g of zeolite X (SILIPORITE® G5 from CECA SA), counted in anhydrous equivalent, are placed in suspension in 300 cm 3 of water.
- the pH of the suspension is lowered from 10.5 to 7 by adding 18 cm 3 of 2N nitric acid.
- 50 cm 3 of a 0.188 molar silver nitrate solution are added to the suspension.
- the suspension is then stirred at room temperature for 3 hours.
- the zeolite thus exchanged with silver is dried at 100 ° C. for 2 hours, then ground using a RETSCH turbine mill equipped with a 0.08 mm grid.
- the sizes of the zeolite particles are between 0.5 and 20 ⁇ m. Under these exchange conditions, almost all of the money involved is exchanged in the zeolitic structure.
- Example 2 Effect inhibiting odor and proliferation of bacteria.
- the test can be carried out either on a real pooled urine sample, or on synthetic urine prepared when the time comes, according to the following composition:
- the inoculum is prepared with 20 ml of real or synthetic urine, 0.5 g of urea and either 2 g of contaminated fluff (already having an ammoniacal odor), or a selected bacterial strain. The mixture is incubated for
- the inoculum has a marked odor, a sign of satisfactory growth.
- the bacteria concentration expressed in cfu / ml, is measured in order to carry out a reproducible sowing.
- hermetic polyethylene boxes are prepared as many times as there are products to be tested. In each box, place a 6 cm x 7.5 cm square of cellulose buffer (fluff) weighing approximately 3 g and containing approximately 0.75 g of superabsorbent dispersed in the mass, with or without the addition of anti-odor products to test. 30 ml of real or synthetic urine, inoculated at the rate of 10 4 cfu / ml, are poured onto each square. The dishes are closed and incubated overnight at 37 ° C in an oven.
- cellulose buffer weighing approximately 3 g and containing approximately 0.75 g of superabsorbent dispersed in the mass, with or without the addition of anti-odor products to test.
- Counting of bacteria After evaluation of the odor, a count of microorganisms is carried out for each type of sample. To do this, the samples are diluted with 70 ml of sterile water and counted using Millipore plates. The result is expressed in cfu / ml.
- the control is made with the ordinary superabsorbent, Aqua-Keep®D (SAP).
- the superabsorbents of the invention are Aqua-Keep D / Zeolite X-Ag (SAP / X-Ag) compositions in variable quantities and at a rate of Ag.
- the following table relates panel notes (note 0 to 5) and bacteria count (cfu / ml).
