High softening temperature synthetic alkylsilicone wax
View Patent ↗A method for making high softening point linear and cyclic alkylsilicone waxes includes reacting a C30+ alpha olefin wax with a silicone hydride polymer in the presence of a catalyst. The high softening point linear and cyclic alkylsilicone waxes have softening points approximating those of natural waxes and, in consequence, can be used in applications which traditionally employ natural waxes.
