Unit 2, No. 1 Endeavour Road CARINGBAH NSW 2229 Gary Lawrence Spradbrow ANDERSON-TAYLOR ASSOCIATES, Registered Patent Attorneys of 10 Harrison Avenue BONNET BAY N.S.W. 2226 Complete Specification for the invention entitled: AN IMPROVED DISINFECTANT OR CLEANSER The following statement is a full description of this invention, including the best method of performing it known to me: This invention relates to disinfectants or cleaners and more particularly, although not ekclusively to a type of product for use in urinals and toilets etc.

Existing disinfectants for this purpose typically comprise Paradichlorabenzene crystals. These however contain Chlorobenzenes which can cause both environmental damage when the residue is flushed down drains and also liver, kidney and spleen malfunction if not handled correctly. Further, these chemicals dissolve in air even during periods of non-use which reduces their effective life.

It is therefore an object of this invention to ameliorate the aforementioned disadvantages. Accordingly a disinfectant or cleaner for controlling and neutralising malodours by molecular S: encapsulation is disclosed, said disinfectant or cleaner comprising by weight 30% to 60% sodium sulphate, 30% to 35% ethoxylated fatty alcohol detergent, 5% to 7% calcium stearate and 1% to 7% sodium percarbonate.

Said disinfectant or cleaner has the advantage of being activated 0. only contact with water, being degradable into nonpolluting water and carbon dioxide and being nontoxic.

An example of such disinfectant or cleaner is described as follows:

INGREDIENTS

BIODEGRADABLE ETHOXYLATED FATTY ALCOHOL DETERGENT......60.00% SODIUM SODIUM PERCARBONATE 10.00% s 04- s MANUFACTURING PROCESS EXAMPLE The materials are amalgamated in a heated vessel.

As the temperature is increased to approximately degrees C bonding of the materials occurs resulting in a homogeneous mass wh-ch is then plodded to produce a semi-solid substance for cutting or stamping into an end product.

EQUIPMENT USED: Stainless steel ribbon blender of 150 kg capacity Double vacuum soap plodder with heated extrusion head Variable length continuous feed cutter All materials are weighed before addition and are added to the operating blender in the S"following order and proportions by weight.

o Sodium Sulfate' 30% to Detergent Powder 30% to Calcium Stearate 5% to 7% Sodium Percarbonate 1% to 7% Perfume 1% to Colour pigment 0% to .01% The product is mixed for 10 minutes before sampling for homogeneity. The blender is then restarted and -3the product is fed into the primary hopper of the plodder. The plodding is done for 15 minttes under a vacuum of 50 cm of Hg and at a temperature between 48 and 60 degrees C.

The plodder extrusion head is heated to 55 degrees C and the product is then extruded in a homogenous continuous stream.

The product is fed to an inline cutter and then packed after a stabilizing and curing time of minutes.

When sodium percarbonate dissolves it disassociates into two products, sodium carbonate Na 2

CO

3 and hydrogen peroxide (H 2 02). A typical reaction is 2 NaCO 3 3H2O 2NaCO 3 3H202 .2 23 2 The hydrogen peroxide provides the bleaching and disinfecting action while the sodium carbonate acts as a base in an acid base reaction with uric acid.

The slow solublising and releasing action is provided by the calcium stearate and the ethoxylated fatty alcohol detergent in combination.

Goo: While the invention has been disclosed with reference 0 o. to the currently preferred example it is to be understood that the foregoing is offered primarily for the purposes of illustration. It will be readily apparent to those skilled in the art that further 6 variations in the formulations and uses of the 0 "compounds disclosed herein may be made without departing from the spirit or scope of the invention.

Claims

1. A disinfectant or cleaner for controlling and neutralising malodourg by molecular encapsulation said disinfectant or cleaner comprising by weight to 60% sodium sulphate, 30% to 35% ethoxylated fatty alcohol detergent, 5% to 7% calcium stearate and 1% to 7% sodium percarbonate.

2. A disinfectant or cleaner as claimed in claim 1 further including by weight 1% to 5% perfume and up to .01% colour pigment.

3. A process when used for the production of a disinfectant S: or cleaner as claimed in claim 1 comprising: S. amalgamating said ingredients in a ribbon blender, Ssubsequently plodding said amalgamation under a vacuum and extruding said amalgamation for cutting into blocks and packaging. *o Dated this 30th day of July, 1993 0 e *Ga ao 0* S.
