Cream of Tartar

Cream of tartar is  often used in cooking to strengthen the matrix of  bubbles in products like egg white when being whipped so it does not collapse too readily.  The same can occur when adding it to bath products such as bath bombs and bubble bars to create large, luscious, stable bubbles.  When used in combination with bicarbonate of soda it helps create a light, aerated product to create the right texture you need for success.
