  • Patent number: 6500218
    Abstract: Novel transparent stiff gel candles comprising a hydrocarbon oil, one or more hydrogenated triblock copolymer of a thermoplastic rubber. This invention is related to candles in the form of firm gels, and more particularly to stiff heterophase, thermally reversible mineral oil gels, preferably white oil gels. The candles of the invention contain block copolymers and blends thereof, the copolymers being preferably derived from styrene-rubber block units. The candles are naturally transparent and uncolored. The gelatinous elastomer composite exhibits a novel combination of properties including unexpectedly low processing temperature, high elongation and tensile strength and excellent shape retention after extreme deformation under high velocity impact and stress conditions.
