Liquid chalk is a special form of magnesium carbonate (MgCO₃), offered in liquid form – typically a mix of magnesium carbonate, alcohol, water, and sometimes skin-friendly additives like aloe vera or essential oils.

What exactly is Liquid Chalk?

Magnesium carbonate – the same active ingredient as traditional dry chalk – absorbs moisture on your skin.

Mixed with alcohol (usually ethanol or isopropanol) so it dries quickly. As you apply it, the alcohol evaporates and leaves behind a thin, dry layer of chalk.

Simply rub it onto your palms, let it dry – done.

✅ Advantages over regular chalk:

• No chalk dust in the air – ideal for gyms, living rooms & home equipment.

• No crumbs, no spills.

• Often lasts longer on your skin than powder chalk.

• The alcohol also provides a light disinfecting effect.

💡 Use cases:

• In climbing and bouldering gyms
