Description
~0~3~
There are nu~erous cleaning agents. Most of the commerclally available cleanlng agents are soaps and detergents. A soap may be a salt of a long chain fatty acid such as a sodium galt of stearic acid or a sotlum salt of oleic acid. A detergent may have a strongly polar group and a large non-polar member such as a strong polar group like sulfonic acid or a sulfate and a large non-polar member such as an alkylaryl unit. Also, the detergent may have a metal member such as sodium to form a godium alkylaryl sulfonate.
The soaps and the detergents may be classified as having a large non-polar member that is oil soluble and polar member that is water soluble.
It is possible to clean certain dirty materials with other cleaning agents such as water alone. The use of water alone is, generally, unsatisfactory and is not used to any extent. Further, there are numerous solvents for dirty materials and such solvents being alcohols, chlorinated hydrocarbon and the like. One cleaning agent which has been used in the past ; and is also used at the present time is a phosphate such as trisodium phosphate.
One of the ob~ections to the use of trisodium phosphate is the pollution intro-duced by the phosphate and also the difficulty of controlllng the cleaning action of the trisodium phosphate. ~uite often the control of the cleaning actlon of the trisodium phosphate is, practically, impossible and fabrics may ~-be damaged and even destroyed.
In preparing this patent application, there were selected, at ; random, from a local supermarket three popular, commercially, available clean-ing agents and which were advertised as detergents.
On the first one of these cleaning agents was written on the box of the cleaninga8ent:

Also, in certain instances there may be built-in blueing agents to glve a more white and cleaner appearance to the material being cleaned and also there may be built-in a bleaching agent.
GENERAL DESCRIPTION OF THE INVENTION
This invention comprises a saccharide, a compound of an alkaline earth metal and a compound of an alkali metal. The saccharide may be one of many different forms such as low polymer starch like dextrin or maybe sucrose or glucose or maltose or other water soluble saccharides.
The alkaline earth metal compound may be of readily available materials such as calcium hydroxide or hydroxides of other members of the second series of the periodic table such as magnesium, barium and strontium.
The compound of the alkali metal may be a salt such as sulfate, carbonate, chloride, citrate, acetate, to name a few. The alkali metal may be sodium or, another member of the first series of the periodic table such as lithium or potassium.
I have performed tests on various cleaning agents made with the saccharides, alkaline earth metal compounds and alkali metal compounds and have found that these formulation produce a cleaning agent which cleans well and does not contain compounds of phosphorus which pollute water.
It i~ to be realized that in the cleaning agent using these basic components of the saccharide, an alkali metal compound and an alkaline ' earth metal compound there may be also used a wetting agent, an anti-deposition agent, an optical brightener, and, if desirable, a blueing agent and a bleaching agent.

DETAILED DESCRIPTION OF THE INVENTION
The cleaning agent of this invention comprises a saccharide, 20an alkaline earth metal compound and an alkali metal compound.
The saccharide may be a monosaccharide, an oligosaccharide having two to ten more saccharide units, or polysaccharide having more than ten monosaccharide units. Essentially, a saccharide is either a simple or compound sugar. The saccharide may be a soluble starch such as a lower molecular unit of starch like dextrin.
Readily available saccharide is sucrose also known as saccharose, normal table sugar, used in the household for cooking purposes.
~ .
' - 4 -: . : ~ :, . ':, '' :,. ~ ':'; ' : ' :, 10~;5730 A readily available alkaline earth metal compount is calcium hydroxide or calcium oxide.
A readily available alkali metal compound is a sodium salt such as sotium chloride or sodium sulfate or sodium carbonate or sodium bicarbonate or sodium acetate or sodium citrate.
These components were blended together to form the basic clean-ing agent. A number of cleaning agent mixes were prepared from these components, see following examples of I through VIII.

In this mixture there is also incorporated mineral oil, lemon extract and liquid blueing. These components were mixed together to form the cleaning agent. The components in the form indicated were stable with respect to each other and could be storet for a long period of time. Also, the components, in an aqueous solution, would react to form sodium hydroxide and calcium chloride. The excess of the saccharose over the calcium hydroxide insured the solubilization of the calcium. The lemon extract functioned as a fragrance for the cleaning agent. In many cleaning agents there i8 incorporated a blueing compound.

The foregoing examples and test~ 6how that these cleaning agents in aqueous mixtures do clean a 60iled or dirty cotton cloth.
In the aqueous mixtures the cleaning agent may unction in such a manner that the calcium hydroxide reacts with the soluble sugar to form a reaction product or a complex of calcium and sugar. Then, the sodium salt may react with the product of the clacium and the sugar of the calcium and the saccharide to form sodium hydroxide and a calcium salt. Or, the sodium salt may react with the complex of the calcium and the saccharide to form a complex or a reaction product of sodium and the saccharide. The complex or the product of the sotlum ant the saccharide may react with water to form sodium hydroxide.
The ~otlum hydroxlde ln the aqueous mixture can act upon the dirt`in the article '` to be cleanet. The concentration of the sodium hydroxide is conerolled in the '~ aqueous mlxture by the soluble sugar present and, also, by the calclum hytroxide present. In thls manner the cleansing properties of sotium hydroxite can be '~ utillzed. The calcium compounds can react with the soluble ~accharides or `~ soluble sugars to form new products of reaction of the calcium and the ;i~ saccharldes. Then, the sodium salts can react with the products or the complexes of the calclum and saccharides. It ls seen that the soluble sugar function~ a~

A review of the foregoing examples shows that there is present a large excess of sodlum salt, on a mole basis, over the calclum compound and saccharide.
This means that there is a reserve of the sodium compound present for reaction with the product or complex of the calcium and the saccharide to form sodium hydroxide in the aqueous mixture.
There may be used a number oS commercially available anti-deposition or suspensoid agents, surfactants or wetting agents, optical brighteners, blueing and bleaching agents in the various combinations of components for making cleaning agents. Also, it is seen that there can be used a wide variety of components for making the cleaning agents. A ssccharide can be used, cslcium hydroxide can be used and many sodium salts can be used.
Further, it is seen that my cleaning agent does not need the use oS a phos- - ;
phorous compound as the three, selected at random, cleaning agents need, see the first part of this written specification. The cleaning agent is bio-degradable. The saccharide will be utilized in nature. The clesning agent can be cohsidered to be biotegradable and, also, free from introducing a lJ compound of phosphorous into the waste treatment facility or into a body of water.
Further, this cleaning agent, or clesning agents depending upon the formulations, cleans the dirt from a soiled or dirty ob~ect in a good fsshion, see the ~xsmples for the clesning of a dirty swstch of cloth, cotton white i~ , .
