AI Technical Summary
Technical Problem
Chalk-based compositions for cosmetic and pharmaceutical use are unstable in aqueous solutions, leading to rapid precipitation and loss of calcium ions, which reduces their effectiveness and causes limestone deposits in pipes.
Method used
A stable composition is achieved by combining chalk with clay in a specific ratio, where the clay swells and stabilizes the suspension, preventing rapid precipitation and maintaining the calcium ions' conductivity properties.
Benefits of technology
The combination of chalk and clay results in a stable, easily applicable composition that retains the therapeutic benefits of chalk, including hydration, skin renewal, and soothing properties, while preventing pipe clogging and maintaining conductivity.
