MCP mixing surfactant: Sodium Deoxycholic acid

Sodium Deoxycholate acid is a surfactant (detergent) that can be used as a component for both cleaning and removal of old varnish and is part of my MCP set (The Modular Cleaning Program). I love mixing this surfactant that consist of the components Deoxycholate acid and Sodium hydroxide 10%. During the process it goes through various stages that look wonderful. You need patience for it. But you will be rewarded. It starts with adding the white powdery deoxycholic acid in demineralised water, slowly wetting the powder on the stirring plate. A creamy white substance is formed. Sodium Hydroxide 10% is added and the following hours a slimy substance is formed. But finally the acid is solved and the solution is cleared! MCP mixing surfactant: Sodium Deoxycholic acid for restoration and conservation is a real miracle!
