Asphalt packets and methods of making and using asphalt packets are provided. For example, an asphalt packet can be provided that include asphalt that comprises an inner volume and a polymer film outer coating that encapsulates the inner volume of the asphalt. The polymer film outer coating can be non-tacky at ambient temperatures to permit stacking of a plurality of asphalt packets under weight without causing the packets to agglomerate.

An improved composition for a thermoplastic elastomer that is used in a product that touches the skin. The thermoplastic elastomer contains a styrene block copolymer, a plasticizing oil, and CBD oil. The plasticizing oil and the CBD oil, in combination, comprise at least eighty percent of the thermoplastic elastomer by weight. The plasticizing oil and the CBD oil have the same, or similar, molecular weights. In that manner, the plasticizing oil and the CBD oil can form a homogenous mixture. The CBD oil saturates the thermoplastic elastomer and will slowly bloom out of the thermoplastic elastomer over time. The migration of the CBD oil brings the CBD oil to the exposed surfaces of the thermoplastic elastomer, therein enabling the CBD oil to be absorbed by the skin.
