Hair gel and oven cleaner have sodium hydroxide?

Answer 1

Not the same amount, though. They use it in hair gel to adjust the pH of the product--if they made 200 gallons of gel that's supposed to be pH 7, and it's pH 6.5 because the ingredients are more acid than usual, they can add just a little lye to the mix and get the pH up without adding a lot of volume to the mix.

Oven cleaner uses lye to melt the food off the oven walls, so they put a lot of it in oven cleaner.

Answer 2

Sodium hydroxide is a common ingredient in both hair gel and oven cleaner because it has powerful degreasing properties and can help break down oils and fats. In hair gel, it helps to style the hair by providing hold, while in oven cleaner, it helps to dissolve and remove baked-on grease and grime. However, it is important to handle products containing sodium hydroxide with caution as it is a strong alkali that can be corrosive and irritating.
