Method for performing aerobic plate counts of anhydrous cosmetics utilizing Tween 60 and Arlacel 80 as dispersing agents.
An aqueous diluent containing Tween 60 and Arlacel 80 gave greater recovery of microorganisms when compared with two common diluents as determined by aerobic plate count of inoculated anhydrous cosmetics. The greater recovery was caused by better dispersion of the anhydrous cosmetics in the diluents.
