I was stunned when I noticed sodium hydroxide in a body lotion that I use, but was relieved to an find that the product is safe.
According to Milton B at Yahoo answers : "You will also notice that it contains hydrochloric acid. The sodium hydroxide/hydrochloric acid are used to adjust the pH of the the final product to a slightly acid level that is compatible with normal skin pH."
yes
If you get sodium hydroxide on your body you should rinse it off as fast as possible and not wait for an answer on the internet! That stuff is bad for you. You should stand under the shower. If you need to ask such a question, you have no business working with sodium hydroxide or anything else with a pH of 14.
I don't know what is sodium hydroxide but what I do know is that anything or any food that is past its expiration date is not safe to use.

Sodium Hydroxide will do the trick.
Because its different and you need to be less worried.
Soap is made by reacting an acid (for example sunflower and olive oils) with an alkali (for example sodium hydroxide). Sodium hydroxide being a much stronger alkali than sunflower oil is an acid, this reaction is done to weaken the alkali so it is not harmful to the skin. This reaction can be seen by dipping (for no more than a second) your fingers into a beaker of sodium hydroxide, the oil on your skin will react with the sodium hydroxide and a thin layer of soap will be formed on your fingers. This is safe to do, and does not hurt in anyway if you have only briefly dipped your fingers in. Some people add fragrances after this reaction has happened.
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
In the same sense that you "can" touch molten iron ... sure. It's not necessarily safe, and a wise person wouldn't do it, but it's technically possible.
You add either sodium hydroxide, sodium carbonate or sodium bicarbonate to acetic acid, and receive a solution of sodium acetate in water. Driving off the water will give you sodium acetate crystals. Hundreds of tons a year are made of this because it has hundreds of uses, so most people who need some just buy it. In a school science lab the safe way to make it is to mix baking soda with vinegar then boil off the water with a hot plate. If you have a factory you make this out of sodium hydroxide and glacial acetic acid, then pour the sodium acetate solution into a pond to evaporate, like they do to get the salt out of seawater.

Calcium Hydroxide is gluten free. Calcium Hydroxide should be safe for patients with celiac and other gluten-related disorders.
