~ 2~ C-4772 SUMMARY OF T~IE INVE~TIO~
Now it has been found in accordance with this invention that a hard surface cleaner containing sodium dichloroisocyanurate dihydrate, an inorganic alkali :':
metal condensed polyphosphate, an alkal1 metal silicate, and both a nonionic and an anionic surface active agent obviatas the dl~ficu].ties inherent in the prior art~;
compositlons. Since anionic surfactants generally result in an unstable formulation when combined with a chlor- .~
inating agent, it is a surprising feature of this ~;
invention that the above composition can be formulated into a stable hard surface cleaner.
:
DETAILED DESCRIPTION OF THE INVE~l~ION
; - ~ More partlcular~ly, the hard surface cleaner of this invention consists essentially of from about 0.lO
to about 5.00/O by weight sodium dichloroisocyanurate di-hydrate1 from about lO to about 60% by weight of an :inorganic alkali metal condensed phosphate; from about 5 to about 500/O by weight of an alkali metal sili.cate;
from about O.l to about 6% by weight of a low-foaming nonionic surface active agent, from about O.l0 to about 15% by weight~of an anionic surface active agent; and from~about O to about 70~/O by weight of a filler.
_ 4 _ , ~ C-4772 As previously indicated, sodium dichloroisocyan-urate dihydrate is a known compound, being described in the aforementioned U.S. 3,816,320.
The inorganic alkali metal condensed phospha~e employed in this invention includes any appropriate soluble alkali metal phosphate suitable for use in cleaning compositions.
By the term " condensed phosphate" in the claims and specification herein is meant a polymeric material formed by the combination of molecules of orthophosphate.
Sodium tripolyphosphate, trisodium phosphate, tetrasodium pyrophosphate, sodium hexametaphosphate sodium pyrophos-phate, and the corresponding potassium phospha-tes are ex-emplary. Sodium tripolyphosphate and sodium hexameta-phosphate are preferred.
Suitable alkali metal silicates which can be employed in the practice of this invention include both anhydrous forms and those containing up to about 25% water. Typical are sodium metasilicate anhydrous, sodium me-tasilicate . i 5-hydrate, potassium metasilicate, sodium orthosilicate anhydrous, etc.
The low-foaming nonionic surface active agents useful in the formulation of this invention are synthetic detergents containing a polyoxyethylene group reacted with an organic hydrophobic compound such as polyoxy-propylene~ aliphatic and aromatic alcohols, the reaction product o propylene oxide and ethylene diamine, etc.
Generally these materials are condensation products of 6-30 moles of ethylene oxide with 1 mole of the hydro-phobic compound and may be either capped or uncapped.
Typical are the condensation products of ethylene oxide with alkyl phenols, commercially known as "Triton"
suxfactants; condensation products of ethylene oxide with~ ;~
aliphatic alcohols having 12-18 carbon atoms such as those surfactants sold commercially as "Tergitol 15-S-9", "Surfonic J-4", etc.
The anionic surface active agents are water-soIuble salts of organic sulfuric acid reaction products con-taining from about 8-18 carbon atoms. Typical are the soaium and potassium alkyl benzene sulfonates suoh as sodium dodecyl benzene sulfonate, sodium tridecyl benzene sulfonate, sodium alkyl sulfonates and sulfates obtained ~
b~ sulfonation of tallow or coconut fatty alcohols and r mixtures of alkyl phosphates, sodium or potassium salts of sulfosuccinic acid, etc.
As a filler, it is preferred to employ alkali metal carbonates such as sodium carbonate and potassium carbonate. These materials may be used alone or in com-bination with such inert fillers as sodium chloride, sodium sulfate, etc~
Minor amounts of compounds such as perfumes, powder~
ing matter, etc. can also be employed in the compositions of this invention.
,~
~ 8 C-4772 In formulating the compositions of this invention, it is preferred to charge the powders, that is the inorganic alkali metal condensed phosphate and any filler, to a mixing container such as a blender. The nonionic surface active agent is added and the components mixed until the nonionic is absorbed into the dry ingredients.
The anionic surfact active agent is then mixed in, followed by the sodium dlchloroisocyanurate dihydrate, and the final composition blended to a uniform m~xture.
As previously indicated, the composition of this invention is an excellent hard surface cleaner. By hard surface cleaner is meant a cleaner suitable for use on non-porous surfaces such as stainless steel walls, holding tanks, pipes, etc. The cleaner is qenerally dissolved in water to the desired concentration which is 1/3 ounce to 1 ounce per gallon of water, depend-ing upon soil and water conditions. The formulation is an alkaline, chlorinated general cleaner. It is suitable for use in dairies, beverage plants, breweries and all food processing plants for cleaning of equipment, floors and walls. It can be used both as a manual cleaner and in high pressure equipment when more wetting ~ is desirable.
,:
~ Z ~ C-4772 While all compositions within the scope of this invention have highly desirable properties, it is preferred to to employ compositions consisting essentially of from about .5 to about 3.5% by Weight sodium dichloroisocyanurate dihydrate, from about 15 to about 35% by weight of an inorganic alkali metal condensed phosphate from about 5 to about 25% by weight of an alkali metal silicate;
from about .5 to about 40O/o by weight of a low foaming nonionic surface active agent, from about 0.5 to about 5% by weight of an anionic surface active agent; and from about 35 to about 65% by weight of a filler.
