CHLOROHYDROL 50 is a 50% aqueous solution of standard Aluminum Chlorohydrate.  The formulation will provide a level of performance that meets the minimum FDA criterion for sweat reduction.

Formula ID:


  1. Mix first three ingredients into a suitable container and measure the refractive index.
  2. In a separate container mix the last four ingredients and measure the refractive index.
  3. Adjust the refractive index of the second mixture to match the first by adding Propylene Glycol to increase refractive index or by adding water to lower it.
  4. When matched, slowly add the second mixture to the first using moderate shear until the emulsion reaches the desired viscosity.
  5. Emulsion particles may begin to settle after two weeks on the shelf, but simple shaking will return uniformity of the product.
