Household cleaning products containing sodium metasilicate pentahydrate

　Sodium metasilicate pentahydrate is widely used with gradually expanded scope of application. In daily chemical industry, it is mainly used for high concentration phosphate-free washing powder, liquid detergent, cleanser essence, tableware detergent. These daily products are widely used in household cleaning. Here are a few specific examples of products and formulations for user reference:

　　P78u—safe non-toxic washing powder with no phosphorus, nitrogen or aluminum: it uses long-chain fatty alcohol made from natural animal or vegetable oil, fatty acid derivatives or saponin as a surfactant. At the same time, it uses sodium carbonate, sodium bicarbonate, sodium metasilicate pentahydrate, modified starch and sodium sulfate as additives. This product is examined by relevant departments to be a non-toxic, safe detergent with negative mutation.

　　P27a—speed ink removal lotion: made by certain substances mixing with water and emulsifying including carboxymethyl cellulose, leveling agent, sodium metasilicate pentahydrate, sodium dodecylbenzene sulfonate, AEO-3, SP-80, ethyl acetate, propylene glycol methyl ether, alcohol and kerosene. It has a lot of advantages: non-toxic; non-corrosive; non-polluting; non-burning; powerful detergency; good fluidity and stability; no metamorphism; good security; quick cleaning speed, etc. It can be widely used in the removal of oil on various items, especially for scrubbing printing machines, rollers and ink on the tape.

　　Magnesium rod is often seen in electric water heater. Due to lack of the knowledge about magnesium rods, it is extremely difficult to clean, let alone the maintenance. Here is a formula which makes use of sodium metasilicate pentahydrate for users.

　　Take 20% sodium alkyl aryl sulfonate, tetrasodium EDTA (dihydrate) 12%, 25% sodium carbonate, sodium dihydrogen phosphate (monohydrate) 10%, and sodium metasilicate (pentahydrate) 33% to mix, modulate into mixture, and then clean magnesium rod with the mixture.

　　In terms of the thermal storage type electric water heater, it generally uses the magnesium rod as anode, which is replaced about once every two years. Be careful when install and replace magnesium rod not to let its anode surface be damaged. Those with no damage have no need to change. Magnesium rods with scale deposit accumulated on its surface, but don’t need to change, can be cleaned by the above mixture.

　　Many places of house are covered with tiles like bathroom, kitchen, toilet, etc. These tiles are easily to get dirty and need to be cleaned. There are many ways to clean tiles. Here introduces a preparation and cleaning method with simple process and easy source of raw materials using sodium metasilicate pentahydrate: dissolve the following materials into 77% water, mix and stir evenly — 6% of sodium xylene sulfonate (concentration is 40%), 4 % of ethylene glycol monobutyl ether, 2% of alkyl benzene sulfonate ether( concentration is 60%) , 2% of straight chain fatty alcohol alkoxy compounds, 3% of sodium metasilicate pentahydrate, 6% of sodium pyrophosphate. without dilution, can be used directly for tile cleaning. It is no need to dilute and can be used in tiles cleaning.
