Definitions
- the invention relates to a liquid hard surface cleaning and disinfection composition.
- the invention more particularly relates to a hard surface disinfection composition that
- Liquid compositions for disinfecting and cleaning hard surfaces like floors, walls, windows, doors, furniture, and table tops in various indoor and outdoor locations are known. Toilets and bathrooms are other places where germs proliferate and
- disinfection and cleaning compositions in liquid form are widely used.
- Other types of hard surfaces that are cleaned by such compositions include utensils and other articles found in households, offices and other public places.
- halogen and active oxygen are two most effective bleaches.
- Bleaches are compounds that liberate oxidising agents like chlorine, bromine, fluorine, nascent oxygen or other oxidizing agents that break the cell walls of microbes like bacteria and virus thereby disinfecting the surfaces thus treated.
- Phenolics are another class of anti ⁇ microbials often derived from essential oils extracted from natural sources which are formulated in an emulsified form and sold as floor and toilet cleaners.
- these compounds are sometimes considered either harsh or take a long time for the antimicrobial action to take place.
- these compositions include surfactants to both emulsify the oily components present therein or to enable cleaning via detergency action. To remove the residual surfactants the surfaces being treated or cleaned are soon thereafter rinsed or wiped to be substantially free of the disinfection/ cleaning composition. This allows very little time for the disinfection action to take place.
- compositions comprising selected ingredients viz. select salts of dicarboxylic or tricarboxylic acids and sodium tripoly phosphate (STPP) in a benzalkonium chloride (BAC) containing composition provides for synergistic antimicrobial efficacy not provided by each one alone or by any of the binary combinations of these agents, in very short time scales of less than 15 seconds.

- Antibacterial Compositions for hard surface cleaning as shown in Table - 1 were prepared. The compositions were tested for antibacterial efficacy using the European Suspension Test BS EN1276 which is briefly described below: A test suspension of bacteria (1 ml) was added to a sample of the product under a certain dilution condition (8 ml) along with a specific soil (1 ml) . The mixture was maintained at 20°C for 5 minutes. After this period of contact time, an aliquot is taken and is immediately neutralized by a validated method. The number of bacteria in each sample are determined by plating in TSA agar and the reduction in viable count is calculated after incubating for 48 hours.
