As I know we can thicken with the salt curve our normal shampoos and other surfactant products I'm just curious how we may go about adding a lot of salt to liquid shampoo or to a shampoo bar & if anyone's tried this"
The Barclay Nicholses are a very oily family, so we're always eager to try new things to get another few hours of out of a washing, but I'm afraid I'm not familiar with the idea of using sodium chloride or normal table salt for oily hair. I have, however, heard of using magnesium!
The salt curve is a way to thicken surfactant mixes - like shampoos - with salt. It does this in two ways. The first - the electrolyte increases the size of the micelles in the surfactants, so the viscosity increases. The second - the electrolytes compete with the surfactants for water, so as we add more salt, we fool the product into thinking we've increased the concentration of the surfactants, which will increase viscosity.
When we add salt to the mixture, there is a dist...
