Abstract
A method for preparing a lotion for reliable high speed processing onto a substrate. The method comprises the steps of providing a carrier system; mixing a premix solution of concentrated premix solution of a solid skin treatment agent in a solvent at a temperature of at least about 35 degrees C., and milling the premix solution into the carrier system at a temperature of at least about 35 degrees C. to disperse the premix solution until an average droplet diameter of the dispersed premix solution is less than about 100 microns. Also disclosed are disposable absorbent articles comprising a lotion of the present invention.
