A polymer/kieselguhr based pale green, odourless powder which is capable of binding and absorbing liquid spillage from a wide range of common chemicals including oils. It will bind/absorb up to 75 times its own weight of water. No dangerous reactions occur during the process. The subsequent gels produced can be disposed of safely. Non aqueous liquids are absorbed by capillary action but with aqueous solutions a binding reaction takes place. Polyethylene glycol is included in the powder to assist the absorption of higher viscosity liquids. The powder does not neutralise the liquids but indicators in the powder colour yellow with acid solutions and red with alkalis. It is recommended that a dust mask be worn when applying the powder. If the powder comes into contact with the eyes flush thoroughly with clean water.
