The silicone composition comprises a product of a reaction of (a) an alkenyl-containing organopolysiloxane having an average per molecule of at least 2 al - kenyl groups and (b) an Si H containing siloxane having an average per molecule of at least 2 Si H moieties. The dispersion also comprises a hydrosilylation catalyst, a polymeric film former and a surfactant of molecular weight below The composition is stabilised in dispersion form by the surfactant dissolved in the aqueous phase and the polymeric film former, and is capable of fo m ing a tacky layer on drying.
