Definitions
- the present invention relates to an aqueous system based on a biocide and a polyorganosiloxane having polyether functions, as well as its use for the disinfection with a lasting effect of hard surfaces by slow, gradual release of said biocide after application, by contact with water from the treated surface.
- Aqueous biocidal compositions for the treatment of hard surfaces generally have the disadvantage of rapidly losing their effectiveness after their application, in particular when the treated surfaces are then washed.
- film-forming organic polymers in these compositions, in order to form, after application, a physical barrier making it possible to combat the too rapid release of the biocide. It has thus been suggested (WO 97/06675 of Rhône-Poulenc Chemicals Ltd.) to combine with a biocide a terephthalic copolyester having in its polymer chain polyoxyethylene or polyoxyethyleneterephthalate units.
- the Applicant has found an aqueous biocidal system of superior performance.

- the polyorganosiloxane structure of the polymer of formula (I) not only allows adhesion and wetting of the biocidal system to the support to be treated, but also creates a preferential interaction between the biocidal and polyether functions, thanks to the high mobility of the polyorganosiloxane backbone due to the low glass transition temperature of the polymer (Tg lower than ambient temperature).

- the effective biocidal activity however extends over 4 washes. There is a slow release of the biocide.
- Example 4 show that a weaker interaction between the biocide and the polyether silicone, by reducing the amount of polyether silicone present in the system, makes it possible to release more biocide for the initial attack of the bacteria.
- the effective biocidal activity spans at least 16 washes.
- Example 5 The results of Example 5 show that if this interaction is further reduced, the amount of biocide released for the attack of the bacteria is even greater. A higher initial biocidal activity and a more effective biocidal activity are then observed on at least 8 washes.
