Abstract

The purpose of this work was to evaluate the formulation possibilities and film characteristics of an in-situ curing 2 parts silicone elastic film. This technology had been previously described in IP 000243125 in September 2015, but recent developments have enabled to expend its breadth of applications. As previously described, DOWSILTM XL-4210 Part A & B is a 2-part solvent-less silicone film-forming technology. It is a thermoset silicone rubber system, with a fast cure at room temperature. After mixing both parts A and B at room temperature at a 1 to 1 ratio, the system cures in a couple of minutes. The cure phenomenon also takes place when the two parts are mixed and applied directly on a surface of many materials including skin and hair, whether they are wet or dry. The resulting films from the above systems are networks of cross-linked and reinforced silicone polymers that are soft, flexible, elastic and long lasting. Co-formulating ingredients, including functional ingredients such as active compounds, vitamins, emollients, humectants, pigments, sparkly and light-scattering materials could be added to either Part A or B or both (or during mixing process) in a Water-in-Oil (W/O), Oil-in-Water (O/W) or anhydrous system to obtain a functional film that cures at the surface of various substrates including skin and other keratinous substrates and that might be peeled-off easily or removed with the appropriate solvent.
