The present invention relates to an agent for the preventive and/or curative cleaning of materials in contact with water, characterized in that it includes sodium chloride and at least one dispersant detergent and/or a non-ionic surfactant having at least one detergent action and at least one oxidizing agent, characterized in that the oxidizing agent is selected from solid-form precursors of hydrogen peroxide and in that the cleaning agent is in solid form, such as pellets, granules, bars tablets, large pellets or powder, the salt(s) being used as binders between the various components. Another objective of the present invention is to provide a method for agglomerating the various ingredients according to the present invention, even when they are present in a liquid form. The present invention also relates to the use of the cleaning agent for the preventive and/or curative cleaning of materials in contact with water.

Preventive and/or curative agent for cleaning materials that are brought into contact with water

A water-in-oil (w/o) or oil-in-water (o/w) emulsion consists of an oily phase that includes one or more oils of vegetable and/or mineral origin, and/or synthesis oils, at least one non-ionic and/or anionic emulsifying surfactant, and an aqueous phase that includes water, characterized in that the aqueous phase includes at least one phyllosilicate, so as to obtain a fluid and stable emulsion over time. The use, the process for preparation, a concentrate of the above-mentioned emulsion as well as its process for production are also described.

Liquid and stable oil-in-water or water-in-oil emulsion with a vegetable oil or mineral oil base

The subject of the invention is a process for treating a 'permeable' architectural material by impregnation, comprising the spraying onto the architectural material to be treated of one or more liquid-phase dispersions of at least one type of photocatalytic compounds based on metal oxide or sulphide and of at least one type of compound for promoting the adhesion of the said photocatalytic compounds to the said architectural material. The invention also relates to the liquid dispersions used and the architectural materials thus treated.
