Patent

CA 2479087

Powdered compositions comprising in admixture inorganic salts and silica gel, and optionally a fragrance additive, are disclosed. The novel compositions are useful in absorbing and deodorizing liquid waste and for removing such waste from irregular surfaces, such as textiles and carpeting, as well as from smooth hard surfaces. The compositions are effective in absorbing liquid biohazards, such as blood, vomit, urine, and other body fluids. For this application, a halogen-containing compound, such as sodium hypochlorite or calcium hypochlorite is preferably included in the composition. The mixtures can also be utilized for the absorption of oil-based spills and hydrocarbons and are also effective in removing moisture and malodors associated with pet urine and other moisture-related stains encountered in the home. When applied to liquid wastes, the absorbent properties of the compositions contain the spill, creating a solid cohesive matrix that allows for easy disposal. Methods for removing liquid wastes are also disclosed.

L'invention concerne des compositions en poudre comprenant un mélange de sels organiques et de gel de silice, et éventuellement un additif de parfum. Ces nouvelles compositions servent à absorber et à désodoriser des déchets liquides et à retirer de tels déchets de surfaces irrégulières, de type textiles et moquettes, ainsi que de surfaces dures lisses. Lesdites compositions permettent d'absorber de manière efficace des dangers biologiques liquides de type sang, vomissure, urine et autres liquides biologiques. A ces fins, un composé halogéné, de type hypochlorite de sodium ou hypochlorite de calcium est de préférence utilisé dans la composition. Les mélanges peuvent également servir à absorber des produits renversés à base d'huile, et des hydrocarbures servent également à éliminer l'humidité et les mauvaises odeurs associées à l'urine d'animaux domestiques et d'autres taches humides que l'on peut trouver chez soi. Une fois appliquées aux déchets liquides, les propriétés absorbantes des compositions retiennent le produit renversé, par création d'une matière cohésive solide pouvant être facilement retirée. L'invention concerne également des procédés d'élimination de déchets liquides.
