SANITARY TOWEL AND SIMILAR OBJECTS WITH ANTISEPTIC PROPERTIES

Abstract: Sanitary towels in particular nappies, pants for infants, women, incontinent adults, treated with paraoxybenzoate of ethylene glycol phenyl undecyl ether, with chemical products in general having a bactericidal, fungicidal, antiseptic and antifermentative action.

Description: Sanitary towel and similar objects with antiseptic properties. The invention relates to sanitary towels in the form nappies, pants and the like to be applied to t procto-uro-genital areas, for infants, women and incontine adults. Sanitary towels by their very nature collect and conser organic liquids. These liquids, being excretions from the body, tend decompose, generate unpleasant smells, infect and irrita the delicate and sensitive parts to which sanitary towe are applied. The object of the invention are sanitary towels in the various forms of nappies, pants and the like to render th suitable for infants, women and incontinent adults, treat with chemical preparations having a bactericidal, fungicid and generally antiseptic action. The treatment is performed according to the various cas both on the raw materials which make up the fluff, such cotton-wool and the like, and on the filtering lining and the fluff or the linings themselves, or on both, duri manufacture of the sanitary towels. In another process the sanitary towels are treated aft they have been manufactured. The treatment is performed advantageously by means of spraying technique which allows either the fluff or t lining material or both to be impregnated thoroughly a easily, as required, either before manufacture of t sanitary towels or during manufacture itself, or on t finished product. A particularly suitable chemical preparation for t purposes of this invention is the following: paraoxybenzoate of ethylene glycol phenyl undecyl eth solubilized in distilled water with the aid cetyltrimethylammonium chloride. The effects of the above preparation have been checked b numerous experiments. The following are the results obtained at the "Institute o Health and Preventive Medicine" of the University of Catani on 1 September 1989. 12 commercially available sanitary towels and 12 sanitar towels treated with the aforementioned chemical preparatio were used. The- sanitary towels were impregnated by means of a sprayin technique. A quantity equivalent to circa 1 ml of the product wa distributed evenly on each sanitary towel. In order to test antibacterial activity at the outer surfac 2 of the sanitary towel, about 4 cm of the surface layer o each sample were soaked with bacterial suspensions of tw micro-organisms: ,- Gram-positive (Staphylococcus aureus ATCC 9144) - Gram-negative (Escherichia coli ATCC 25922). The concentration of these suspensions was circa 10 bacteria per ml. After an hour of contact in an incubator set at 37°C, th samples were pressed onto the surface of a suitable cultur medium (Mueller-Hinton's agar) contained in petri dishes. The dishes were then incubated at 37°C for 24 hours. The number of colonies which had developed was then counted The four columns of the table below give the result obtained: - column A gives the number of colony forming units (CFU) o S. aureus in 12 untreated sanitary towels; - column B gives the number of colony forming units (CFU) o S. aureus in 12 treated sanitary towels; - column C gives the number of colony forming units (CFU) o E. coli in 12 untreated sanitary towels; - column D gives the number of colony forming units (CFU) o E. coli in 12 treated sanitary towels. TABLE Number of colony forming units (CFU) of S. aureus and of E coli A B C D 230 82 250 27 202 80 230 5 199 80 195 6 366 150 190 7 380 43 340 23 215 90 180 0 255 65 205 15 389 71 132 9 108 68 198 11 263 102 150 7 157 88 165 40 336 114 218 21 Average 258 86 204 14 Reduction in percentage 77% 93% As can be seen from this table, the averages of the unit (CFU) of S. aureus were 258 for the untreated sanitar towels and 86 for those treated, while the averages of th units (CFU) of E. coli were 204 for the untreated sanita towels and 14 for those treated. Therefore the reduction in percentage obtained with t chemical preparation tested on the samples compar-ed was 77 for the units (CFU) of S. aureus and 93% for the units (CF of E. coli. The advantages of the invention are clear. Using simple means which do not require complicated a costly systems, virtually all the negative consequence which depend on the accumulation of harmful and decompos substances and their contact, due to the actual nature sanitary towels, with delicate parts of the human body, a prevented and fought, above all avoiding irritations, infections and unpleasant smells.

Claims: CLAIMS 1) Sanitary towels in general, more particularly nappies pants and the like for infants, women, incontinent adults characterised in that they are treated with chemic preparations having a bactericidal, fungicidal, generall antiseptic and antifermentative action. 2) Sanitary towels in general, as in claim 1) , characterise in that the treatment by means of chemical preparations i performed on the raw materials which make up the fluff. 3) Sanitary towels in general, as in claim 1), characterise in that the treatment by means of chemical preparations i performed on the filtering linings of the fluff. 4) Sanitary towels in general as in claim 1), characterise in that the treatment by means of chemical preparations performed on the fluff during manufacture of the sanitar towels themselves. 5) Sanitary towels in general as in claim 1) , characterise in that the treatment by means of chemical preparations performed on the linings of the fluff during manufacture o the sanitary towels themselves. 6) Sanitary towels in general, as in claim 1), characterise in that the treatment by means of chemical preparations peformed on the sanitary towels themselves after the manufacture. 7) Sanitary towels in general, as in claim 1), characteris in that the treatment by means of chemical preparations performed with a spraying technique. 8) Sanitary towels in general, as in claim 1), characteris in that they are treated with a chemical preparati composed of paroxybenzoate of ethylene glycol phenyl undec ether solubilized in distilled water with the aid cetyltrimethylammonium chloride.
