With silicone additives, the differences of the finished products can be felt obviously by the skin. For example, the cream is more lubricious and very soft with the addition of the silicone gum (Formula 4). With the addition of the ethyl methicone (Formula 2) the cream is rendered with a silky feel and the skin looks bright when dry. 

When a multi-domain silicone is used to replace petrolatum, the cream is rendered with a very soft silky glossy feel on the skin and can be played with more time and cushion. 

Addition of a Q resin (Formula 3) results in a powdery feel and dry after-feel. 
Very significantly, partially replacing solid emulsifiers with the correct PEG 8 dimethicone results in a formulation with a significantly more lubricious, softer and smoother feel. 

The control formulation is interesting since it incorporates dimethicone 100 cst into the product. This results in an improvement of the normally sticky oils in he formulation and increases spread.  This approach results in a much better product than if the dimethicone were not present, and the selection of 100 cst results in a combination of increased spreadability and compatibility with the various oils present in the product. Replacing the 100 cst dimethicone (3%) with the multidomain silicone at 1% we believe would provide improved aesthetics over the silicone fluid.
