Another alternative in the manufacturers efforts to increase the capacity per unit area is stacking up thickeners in vertical arrangements. Such units are known as multiple compartment or tray thickeners and consist of two or more conventional compartments up to 35 m in diameter. Each compartment has a set of raking arms operating from a rotating central shaft common to the whole... 

As discussed before (2), multiple emulsions (w/o/w or o/w/o) are ideal systems for application in personal care products for the following reasons. First, one can dissolve ingredients in three different compartments. For example with w/o/w multiple emulsions, one can incorporate two different water-soluble additives (proteins, enzymes, and vitamins) and an insoluble ingredient (e.g., perfume). Second, they can be applied for sustained release by control of the breakdown process that occurs on application. Third, they allow one to produce the same cream consistency required for many cosmetics, e.g., by incorporation of a thickener or gelling agent in the outer continuous phase.
