Sodium Hydroxide 10% Solution is a mixture containing: 10% Sodium Hydroxide (NaOH) by weight 90% Water by weight
It is a strong alkaline (caustic) solution commonly used in industrial, cosmetic, cleaning, and laboratory applications.
Important: Always add sodium hydroxide to water, never water to sodium hydroxide, because the dissolution generates significant heat.

Common Industries Using 10% NaOH Solution
Soap and detergent manufacturing
Cosmetics manufacturing
Food processing (equipment cleaning)
Water treatment plants
Chemical manufacturing
Industrial cleaning
For cosmetics, a 10% sodium hydroxide solution is often used as a convenient stock solution for pH adjustment because it allows more accurate dosing than using solid NaOH pellets.
