Abstract: An emulsion comprises a non-aqueous phase including a solid silicone polyamide copolymer and a silicone fluid, an aqueous phase including water, a chaotrope soluble in the aqueous phase and capable of liquefying the solid silicone polyamide copolymer in the absence of the aqueous phase at a temperature less than 45 C, and an emulsifier. A method of preparing the emulsion is also provided. The method includes combining the solid silicone polyamide copolymer, the silicone fluid, and the chaotrope at a temperature less than 45 C to give a liquid silicone composition. The method also includes combining and shearing the liquid silicone composition, the emulsifier, and water, thereby preparing the emulsion. Personal care products and similar compositions including the emulsion are also provided, along with methods of making and using the same.
