Abstract

The present invention is an improved liquid toilet bowl cleanser comprising a fluorosurfactant coating agent, an anionic or non-ionic cleaner and a rheology control agent together with other minor excipients The flurosurfactant continually adheres to and coats the porcelain surface of the toilet bowl during the active life of the cleanser composition preventing the formationof toilet bowl stains and mineral deposits for a substantial period of time after manual cleaning.

MANUAL TOILET BOWL CLEANER

Field of the In.:~nlion The present invention relates generally to cle~ s and disin-fe~ ~ for toilets and urinals. More sl-c- ;r~ y~ the pr~ul invention relates to an i.l~l,ro~ed liquid toilet b~ le~ning co...po~ilion that pr~ es conLillual and long lasting cle~n~er action and pr~tJ~ ;on through the depo~-10 tion of a co~ting agent about the e~osed ba vl surface.

Background of the Invention Many efforts have been made over the yea~ to make thedrudgesy of cleaning bathrooms, and toilets in particular, less of an ~,npleas-15 antchore. Whereastoilet~le~ninggenerallyre.l..i~d the ligo-ousscrubbing of the bowl with a brush and an abrdsi.e powdered bleach or det~,gent, autom~t-c toilet bowl cleaners have been around now for a number of years -and re~luih~ little more effort than the ., ~ ~.z~ flush that one cQndn~s after each use. These cleaners generallyconsist of a liquid, a solid tablet or 20 a granular material that is ~llv~ed in the cistern or tank which sits atop the bowl. Liquid and granular formlJIqti~-nc are generally pro~ided in plastic dispensing con~aine,a or bottle_ wherea the solid fo~ tionc may just con~ct of the solid tablet itcelf. The cle~ r slowly dissol~es in the water of the tank and with each flush is lcle~ced to the bowl where it sw~rls 25 about, cle~ncin~ and dicinfecting the anionic l~o.~lain surfac~

Solid ldvatol~ or urinal ~ --c are commonly ut~ized today to clean, deodonze and disinfect toilet water and to~let fix-tures These co ~P~ C are ~rpjcally shaped in the form of "bloc~ or "cakes" and are placed by the u_er in the toilet tank or bowi, or in ~ qlc 5 The blocl~s are then designed to slawly diss~h_ .,nt lhe.~ l~lu~ part of their act~e c~ over time. It ;c this time-~ It~clcA al~,ll,.,tc which many have fount to be invaluable in ~ p~ g ~r.r.~ l agenS to the water. In many ~i~ces, the action of ll..cl.;..g also serves to fur~er e..sc ~e active ingredien~
Liquid toilet bowl cleaners on the other hand must be applied manually and are generally co.l,~.~d of gel or viscous liquid that is squirt-ed from a squeezable container or bottle about the uppcr rim of the toilet bowl. Some formulations are left to slowly coat the bowl surface through gravitational pull and clean over several hours or, in most cases, a brush is used to manually scrub the surface and the dirt, grime and soap scum is then flushcd away.
There are many dirrer~nt formulations known in the art with r~.e~ I to both types but all generally c~ plise a water soluble surfactant, a halogen Icle~,l.g agent, binders, dyes, fillers and pcrfumes.
Sul~ac~ b, more g~ ne.ically known as soaps or delcrgent$
are surface active agents that clean soiled or stained surfaces by lu. ~ g the ~ ~ t~ or surface energy that binds two ~ate.ial$ in this case two solids, together. Suf~c~ntc concentrate at the solid-solid or solid-liquid interface bel~ eell two materials and reduce the surface tens;on at this point thereby s~a.alillg the two which cleans the surface.
Many toilet bowl ck~ilc~ls employ a variely of halogen-con-taining lua~lials that are known to sen~e as ~ ;,.r~ and/or s,~. ;I;~;.~g agents. These ".ate,ials are believed to function as disinfecting agents by virbue of the ~o~ alioQ of a hypohalite ion, e.g., hypochlorite ion, or hypoha-lous acid, e.g., hypochlorous acid, when the material is dissolved in an ~ 3-13 US

The dye or coloring agent iUlpal b a colored hue to the other-wise clear toilet bowl water and this serves two purposes. On thc one hand, the dye adds a certain aesthetic value in that the blues and greens of the dyes lcnown in the art are ple~~ing to the eye.

The surf~ces of mosttoilet bowls on the other hand, is generally ~ll~yl~ed of pol~clain wDich is susce~ le to attack by the ions formed by these cc, .l~unds when disso~ed in ~ater. The toilet bowl sur~aces are generally anionic by nature while many of the halogens, sur~actants and dyes form cations when rele~ in 25 solution. These cations, as well as naturally oc~;u,.~g minerals found in the ~e..ls water w~l often bond to and stain the anionic ~,ol~lain surface.
Orange iron spots are commonly seen as a result of high iron levels in the water supply. If left untreated, these can become quite llnce~mly and are difficult to remove at best.

It is an object of the p~e~nt invention to provide a sustained release, continual dispersion of a toilet bowl ~le~ r which not only cleans but plOt~ toilet bowl surfaces as well.

Two Arnerican Staru~ard toilets were thoroughly cleaned and flushed several times with water. One toilet was then cl~ed with the above r~fere..c~d formulation (the productwas dispensed through an angle-30 neclc botsle under the rim and allowed to sit on the surface for 10 minutes, and then brushed and flushed). The other toilet received no treatment. An equal amount of a fish oil stain, colored browo and thicl~ned, was ~ o~
applied all around the inner surface of the bowls of both toilets. After vraiting 5 ~"inutes~ both toilets were flushed five times.
