Improved product for transformation of a toxic corrosive or environmentally-noxious liquid product into a non-corrosive or non-noxious residue

Abstract

The invention relates to a product for transformation of a toxic corrosive or environmentally-noxious product into a non-corrosive or non-noxious residue, comprising at least one amphoteric agent, at least one lipophilic absorbent, at least one hydrophilic absorbent and at least one binary colored indicator, selected from the group of the following mixtures: Nile blue / alizarin red, alizarin yellow / alizarin red, thymolphthalein / methyl red, phenolphthalein / methyl red and tropaeolin OO / thymol blue and optionally an additive selected from the group comprising charge agents, granulation agents, anti-static agents and mixtures thereof.

Description

technical field

[0001] The present invention relates to an improved product for converting a corrosive or environmentally harmful toxic liquid product into a non-corrosive or non-harmful residue. Background technique

[0002] Such a product, which is also considered a neutralizing product, has been disclosed in French patent FR 2 784 589 and European patent EP 995 492 . Although very effective, it is impossible to know whether the dispersed toxic products have been completely neutralized. The user is therefore inclined to increase the dosage of the neutralizing product to ensure that the residue can be disposed of without risk, or as an alternative he must measure the pH of the residue.

[0003] Acid-neutralized products and basic-neutralized products are commercially available that contain a color indicator that directly identifies the pH range of the residue.

[0004] These products are for example manufactured by Haleco under the brand name and products for sale. ...
