Alkyl-phosphates as new substances for disinfection and decontamination "bio-chem"

Abstract

A series of substances recommended as biological or chemical decontamination agents and new synthesized substances (e.g. Alkyl-phosphates) were tested. Among these we selected the microbiocide Alkyl-phosphate 2005, a complex mixture of aminosalts: mono- and bi- Alkyl-phosphates, which have in their molecular structures a variable percent of free acid functions were selected. It is a universal micro biocide with bactericide, fungicide, algaecide effects, with multiple uses, reduced toxicity and a minimum ecological impact. The products are liquids or solids, depending on their ester groups structures (R1, R2, R3 = ALKYL or/ and ARIL) and amino components. The solubility of these products in water or in different common solvents is also a condition of their molecular structures. The substances are characterized by a high chemical stability to storing, solar radiation, and atmospheric oxygen etc. Also, the products are chemically stable in conditioning compositions and in direct contact to protected materials. The product is insoluble in water but is soluble in different organic solvents. After washing the objects or wetting the surfaces by spraying, the product makes a residual layer with disinfectant properties for a long period of time. The mixtures of compounds (I) and (II) are characterized by a strong microbiological activity developed, even at low levels of concentration (0.07% - 0.2 %), on a wide spectrum with bactericide, fungicide, algaecide effects etc., having at the same time a repellent and insecticide action. Laboratory tests proved the effectiveness of these products for positive-gram bacteria and also for negative-gram bacteria. These substances are characterized through a low toxicity for mammals and human subjects, feature that doesn't impose specific measures in labor protection during preparation, conditioning, handling or use. Even more, when contacted with STL or toxins, these substances usually decompose into non-toxic compounds. By proper conditioning, products with multiple decontaminant effects can be obtained. The Alkyl-phosphate 2005 product can be used with very good results also as a decontaminant against bio-terrorism attacks.
