Where To Buy Naoh LINK
Because people now use caustic soda to make illegal drugs, it's harder to buy large quantities than in the past. However, different sizes are available in stores and online. Thus, it is not uncommon to find customers asking where to buy sodium hydroxide UK.

It is crucial chemical in the food industry where it is commonly known as lye. Sodium Hydroxide solutions are used in the peeling of fruits and vegetables, and bagels and pretzels acquire that distinctive, shiny, brown appearance as a result of being baked after their introduction to a solution of Sodium Hydroxide.

This sodium hydroxide is packed by us in-house. There is therefore NO mechanised bottling where any traces of hydrated silica powder might be introduced. If you are concerned for the purity of your lye then this product should be your preferred choice.
Hawkins is where to buy Sodium Hydroxide wholesale. Hawkins carries high purity sodium hydroxide commonly referred to as caustic soda. We also carry sodium hydroxide in bulk and in multiple packaging options as well as in multiple grades. Hawkins distributes both liquid and dry caustic soda.
The chemical is synthesized through electrolysis where chemical decomposition is achieved by passing an electric current through a solution of sodium chloride (commonly referred to as table salt) to yield sodium hydroxide and chlorine gas.
There are however some issues when electrolyzing NaOH.As the sodium floats on the lye bath, precautions should taken place to prevent drifting of the sodium to the anode where it oxidizes again.
Water vapor is formed at the anode which can react with the sodium and evolve hydrogen gas. Combined with the oxygen this may cause explosions which mght splatter the hot lye around and when this touches the skin this is NOT FUN.
The temperature should be within a narrow range of 320 and 330C as above 330C the sodium metal dissolves in the lye and electrolysis will cease. This requires a good temperature control and thermocouple sheathing which is resistant to the lye.
After doing some not quite successful tests with the 'carbon method'(see more below) I was trying to electrolyze NaOH by using hardware shop grade NaOH pellets. However I watched this video which discouraged me from doing the electrolysis due to the aforementioned issues.First electrolysis test: could not collect the sodiumBut Later on I made a setup for a simple test. I bought a stainless steel Senseo coffeepad container for a few $$ (8cm diameter, 20cm tall) which Icut off till 7cm tall. This would be the container in which the lye is to be electrolyzed. I surrounded this by two pieces of cell concrete (Ytong) breeze blocks with a cutout for the S/S container. I put two electrodes into it a nickel anode (which is also used in commercial Castner cells) and a copper cathode.
Over 1000C this reaction is favorable also because the vapor pressure of sodium is well over 1 bar (boiling point 889C). For making my own sodium metal I preferred this process. Electrolyzing NaOH or NaCl is a rather tedious job for an amateur chemist because of the Na metal floats on the liquid salts and is not easy to protect the hot molten metal from burning in air. But collecting sodium metal is easier than with the carbon method. This method however requires capturing of the Na vapor under an oil bath, but that is easier to handle than it seems. The biggest challenge is to keep the retort airtight. At those temperatures, plain steel is easily attacked by oxygen from the air. Stainless steel is the best option. Actually, inert gas like Argon should be used to prevent oxidizing the metal vapor. The setup with the retort in a sandboxThe challengesAs the process requires temperatures of over 1000C you need a furnace which reaches that temperature. That is rather easy if you have a propane burner. See this furnace page for more info. As the sodium metal is released in gaseous state, the vapor should be condensed and collected where it cannot react with air or water. Mineral oil is a good option however it is flammable.
What does it mean if a product isn't displaying stock quantities and instead lists "Stock Delay"? As products are sold and restocked there may be times where a particular product/size isn't physically in our warehouse, yet. This doesn't always mean that the manufacturer is out of stock though.
Our ancestors made their own wood-ash 'lye', which is usually a tad stronger (higher pH) than baking soda, but nowhere near NaOH in strength. Similarly, Chinese 'lye water' is also 'wood-ash' (soda-ash) or commonly, a mixture of sodium carbonate and potassium carbonate. OK for noodle-making and a little bit stronger than baking soda. I doubt it would be as effective as NaOH for pretzels. If you use a weaker alkali, you may need to soak (or simmer) your pretzels in your alkaline solution for a longer time, which may not make the best pretzels. I've never tried it
Can't speak for Europe, but food-grade lye is readily available everywhere in the U.S. Just go down to the nearest hardware store. I get mine at the local ACE, for instance. Cost's less than four bucks for a pound---which lasts two days longer than forever.
Dark beer is high in melanoidins that it gets from the dark malt that it is made from. Bread crust has some melanoidins, which is why bread and dark, malty beers can have a similar aroma. If you really want to max out the melanoidins in your bread crust, though, you need to raise the pH. That's where the NaOH bath comes in.
The bagel boards are carefully tipped/flipped about 3-5 minutes into the baking process so that the bagel falls off the board and now rests on the stone where it finishes baking for the next 12-15 minutes.
LANCE HALL: There are several sites out there. One of the most informative on what biodiesel is, where it's being used, is biodiesel.org. That's the National Biodiesel Board website, lots of good information there. It won't really tell you as much how to make it, but hopefully, this will be one of the more informative sites that you'll actually be able to see somebody make one, make a batch.
Dear All,Thank you very much. I dont think its technically OT, because I need to reassure what I am going to do is a "GRAS" thing, well yea includes the "commercial" thing too :)This is really testing my guts. Again, does the FG NaOH really exist? Moreover, does it really safe for food purpose? I am lookin' for some new hints, and I found this: -19707625Based on that link, I have to revise my own statement, the NaOH actually (could be) granted as GRAS one. The keypoint is, the "Sodium hydroxide is prepared commercially by the electrolysis of sodium chloride solution and also by reacting calcium hydroxide with sodium carbonate." Perhaps, if the NaOH is made from Sodium carbonate, it will gives a "food grade" charateristic? Again, its only my speculation.Another interesting parts from the document is: "The affirmation of this ingredient as generally recognized as safe (GRAS) as a direct human food ingredient is based upon the following current good manufacturing practice conditions of use: (1) The ingredient is used as a pH control agent as defined in 170.3(o)(23) of this chapter and as a processing aid as defined in 170.3(o)(24) of this chapter."And..."The ingredient is used in foods at levels not to exceed current good manufacturing practice."The question is, which GMP level that the document is sayin'? So I search again on the related documents and I found: -gras-19707112 -19706720Still, not declaring the exact "numbers" that I want to. So I do some research again and I get this magic "1%" number (on the 10th section, page 5): _Hydroxide.pdfWhich eventually leads me on the further searching of the previous document: -19706090So, even it only a case for modified food-starch, does it makes any sense that applying maximum of 1% FG NaOH is considered as a safe thing to do?Regards,AryaPS: I am really grateful if someone could tell me where the heck I can buy this FG NaOH... 041b061a72
