A decrease in the area of the oxirane ring at 915 [cm.
The silanes bis(triethoxysilylpropyl) tetrasulfide (TESPT) and 3-aminopropyltriethoxy silane (APTES) were used in combination with ENR containing 25 mol% oxirane rings (i.
New classes of silicone gels suitable for hair products have recently been disclosed; these are produced by hydrosilylation of oxirane ring compounds such as epoxides, (1) by forming branched molecules with a silicone core and hydrocarbon branches, or networks formed from these branched units.
Prior to joining Sartomer, Horgan work at DuPont and Oxirane.
