Dendritic Salt is a finely ground grain salt that has been crystallized to provide increased surface area. Although not visible to the human eye, Dendritic Salts have a star-shaped surface area that helps to retain fragrance, requires less pigments and reduces the caking and clumping that can occur in salt formulations. Add approximately 5% Dendritic Salt to your bath salts to increase the longevity of the aromatics included in your salts. Combine Dendritic salt with medium and/or coarse grain salts if you prefer chunkier salts. To use, mix your essential or fragrance oil with your Dendritic Salts and then blend the Dendritic Salts into your other salts.
