  • Hydrochloric acid instead of citric acid to adjust SLS powder pH

    Posted by Abdullah on February 5, 2025 at 3:57 am

    The SLS powder that we use has a lot of base. When we neutralize it with citric acid, it creates a lot of foam. <div>

    I saw a YouTube video citric acid+sodium hydroxide reaction and it created bubbles.

    I saw another video hydrochloric acid+sodium hydroxide reaction and it didn’t create any bubble.

    So if i use hydrochloric acid instead of citric acid to reduce SLS powder pH, would it create foam or not?

    0.8% citric acid is needed to reduce pH of 1% SLS powder to 7.

    I am asking this because here hydrochloric acid not available locally to test. I have to import it.
