  • Silicones as skin conditioners

    Just for fun I decided to make a luxury body shampoo using mainly Ecocert surfactants. (Plantapon LGC Sorb, Dehyton G, CAPB). For the luxury aspect I added 1% of Silsense DW-18 (dimethicone copolyol ester, a water-dispersible silicone). The results surprised me in that I seem to be getting skin conditioning effects (wrinkle reduction, smoothness improved). It is specified for skin use, but what I want to know is, for daily use in the shower is there any concern with buildup in the skin, anything like that?

    I don’t think you could get build-up as it appears you have hydrophobic exhaustion to skin due to isostearyl moiety on the silicone backbone.Usually build up does not come from an exhaustive process but rather is due to charge effects: it (build-up) results from coacervation.You can test this via making a 10% solution (shower conc) and let sit o/n and centrifuge or look closely for a separate layer on the bottom —-if there is nothing then not likely coacervation and build-up potential.
