Abstract: Disclosed is a sustainable shower apparatus (1) comprising: (i) a pressurizable container (2) to hold water (3) and a gas; (ii) a pressurizer (4) for pressurizing said container; (iii) a shower head (7); (iv) a first tubing for carrying pressurized water from the container to the shower head; (v) a second tubing (8) for carrying pressurized gas from the container to the shower head; where flow of said gas or water is individually controllable by use of respective valves (6, 9) and where each tubing terminates into a respective nozzle (10, 11) in said shower head which comprises a nozzle for spraying said gas and adjacent thereto, at least one nozzle for spraying the water, wherein tip of each nozzle for spraying water is oriented at an acute angle with the tip of nozzle for spraying gas.

Abstract: Disclosed is a shower apparatus comprising: •a housing (1, 2, 3) for an object (4); and •a plurality of set of coplanar nozzles inside said housing, the nozzles allowing for a simultaneous spray of a pressurized gas and a liquid on said object. Each set of nozzles comprises a first nozzle (7a, 7b, 7c) for spraying for spraying said gas and adjacent thereto at least one further nozzle (6a, 6b, 6c, 8a, 8b, 8c) for spraying said liquid. The axis of the nozzle for spraying said gas is arranged at an acute angle with respect to the axis of the nozzle for spraying said liquid. The nozzles are configured to provide improved cleansing in a single shower while consuming less water.

Abstract: Disclosed is a sustainable shower apparatus (1) having: (i) a housing (2) for an object (3); and (ii) plurality of shower heads (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b) positioned at different heights for spraying a mist comprising a pressurised gas and a liquid on said object; wherein each shower head comprises at least one set of nozzles, where each set comprises: (a) a nozzle (22) for spraying said gas; and (b) adjacent thereto, at least one nozzle (20, 22) for spraying said liquid, and wherein in each said set, the tip of each nozzle for spraying said liquid is at an acute angle to the tip of each adjacent nozzle for spraying gas.

Abstract: The invention provides method for the evaluation of washing or cleaning techniques on a substrate comprising: i. applying a selective indicator system on the substrate to be evaluated; ii. washing the substrate with water and/or detergent containing composition; and ii. contacting the washed surface with an indicator complimentary developer, whereby inadequate washing is indicated when upon contacting of the developer it acts on the unwashed indicator to develop a colour indicative of the insufficient washing or cleaning.
