Long term stable, oil-in-water emulsions that have a high concentration of plasticized MQ-type resin and/or its derivatives in an internal phase. Also, novel compositions for topical use that comprise our MQ resin emulsions. These compositions include, hair care products, especially for treating split ends, skin care products, such as sunscreens, and systems for delivering actives to skin and hair. In some preferred embodiments, the MQ emulsion is stabilized in such a way that the surface tension of the emulsion is sufficiently close to the surface tension of a target surface, such as damaged hair or skin.
