Popular questions
What is sodium hydroxide used for?
In foods, E524 (sodium hydroxide/lye) is used as a pH regulator and processing aid—for peeling fruits and vegetables, curing olives, Dutch-processing cocoa, and creating the characteristic crust on pretzels and some noodles. Outside food, it’s widely used in soapmaking, cleaning, and pulp and paper production.
Is sodium hydroxide a base?
Yes—it's a very strong base (alkali) with a high pH and is highly caustic; in foods it's used only in small, controlled amounts.
What is the chemical formula for sodium hydroxide?
NaOH.
What is the formula for sodium hydroxide?
NaOH (composed of sodium cations, Na+, and hydroxide anions, OH−).
How to make sodium hydroxide?
Industrial sodium hydroxide is produced by the chlor-alkali process (electrolysis of brine), yielding NaOH, chlorine, and hydrogen. Do not attempt to make it yourself; for any food use, only purchase certified food‑grade lye.
Is sodium lactate dairy?
No—sodium lactate is not a dairy ingredient; it’s made by fermenting sugars (e.g., corn or beets) and contains no lactose or milk proteins.
How much sodium lactate in soap?
Typical use in cold-process soap is 0.5–3% of the oil weight (about 1 teaspoon per pound of oils), added to cooled lye water; using too much can make bars brittle.
What does sodium lactate do in soap?
It makes bars harder and easier to unmold, helping them last longer and feel smoother; in liquid soap it also acts as a humectant.
Is sodium lactate natural?
It’s generally considered naturally derived—made by fermenting sugars to lactic acid then neutralizing with sodium—though “natural” labeling depends on local regulations.
Does sodium lactate contain dairy?
No; despite the name, it doesn’t contain milk proteins or lactose and is typically made from fermented plant sugars (if highly sensitive to dairy, you can confirm the source with the manufacturer).
