The invention relates to a granular cleaning agent for sanitary facilities, comprising tensides, alkane carboxylic acid salts, and solvents, wherein the proportion of alkane carboxylic acid salts equals between 1 wt % and 5 wt % and the proportion of solvents (including perfume oils) equals less than 40 wt % and the agent contains at least 18% non-ionic tensides from the group of block copolymers containing oligo and polyethylene oxides and/or oligo and/or polypropylene oxides and/or oligo and/or polybutylene oxide.

A composition for use on a hard surface. The composition has: (i) at least 7.5 wt. % of at least one surfactant selected; (ii) a blend of linear primary alcohols, or a blend of ethoxylated linear primary alcohols, wherein each alcohol of the non-ethoxylated blend or ethoxylated blend includes a carbon chain containing 9-17 carbons; (iii) a transport rate factor of less than about 55 seconds; and (iv) an adhesion time of greater than about 8 hours.

A lavatory cleansing block including: an alkane sulfonate; a carboxymethylcellulose; a dye; and a hydrophobe; wherein the weight ratio of carboxymethylcellulose to dye in the block is 1.5:1 to 0.8:2 and wherein the block is substantially free of guar gum.

A chemical composition includes citric acid, sodium bicarbonate, starch, at least one oil, and a liquid composition such as water combined to form a solid tablet. The composition may react with water to produce a film over a body of water, such that the film is used to cover the surface of the contents of a latrine and prevent gasses and odors from escaping the latrine.

An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. Preferred devices dispense a first agent for air freshening, and may optionally dispense a second agent, such as a drain cleaner. A workable drain cleaner is structured to permit a slow release of drain cleaning agent. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a polymer or rubber-like carrier material that is infused with the volatile fluid; gravity-induced drip from a bulk supply of volatile fluid through a small orifice onto an emanator; osmotic transfer of volatile fluid from a bulk supply; gas-pump drive of volatile fluid at controlled pressure; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof.

A dispenser system for treating a toilet, the dispenser system comprising: a tray (402) having a rim at least partially surrounding a plurality of compartments (404) housing a treatment composition, each compartment (404) having a first side configured to be closed to flushing water and a second side configured to be open to flushing water, the second side defining an aperture for receiving the treatment composition; and a hanger (406) configured to suspend the tray (402) from a toilet bowl rim; and a cover coupled to the rim for sealing the aperture of each compartment and configured to be removed by a user prior to use.

A solid cleaning agent containment device for toilet cleaning agents includes a tube, which in turn comprise a first segment and a second segment. The first segment has a closed end and an open end, while the second segment has a closed terminus and an open terminus. The second segment is circumferentially smaller than, and adjustably positionable within, the first segment so that the tube is selectively length adjustable to fit substantially between a front wall and a rear wall of a tank of a toilet. The tube can contain a solid cleaning agent and can be positioned in a tank of a toilet. A plurality of holes that is positioned in the tube allows entry of water into the tube and exiting of a solution resulting from dissolving of the solid cleaning agent in the water.

A composition for use on a hard surface. The composition has: (i) at least 7.5 wt. % of at least one surfactant selected; (ii) a transport rate factor of less than about 55 seconds; and (iii) an adhesion time of greater than about 8 hours.

Cleaning compositions in the form of a self-adhesive aqueous gel are provided. The aqueous gel may be a rigid, hard aqueous gel that resists deformation of its shape. The gel composition may desirably have a hardness of at least about 150 g and/or a gel melt temperature of about 50-90 C. The cleaning compositions may include a polyalkoxy nonionic surfactant, such as an alkoxylated alcohol and/or polymeric alkylene oxide block copolymer, a co-hardening agent, and water. Methods for treating a hard surface, such as a toilet bowl, using the cleaning compositions are also provided.

Detergent compositions designed to prevent aluminum discoloration while providing high cleaning performance on soils and stains are disclosed. Detergent compositions substantially free of nitrilotriacetic acid (NTA) are disclosed. Methods of using the detergent compositions are also disclosed.
