Benzyldimethyloctadecylammonium

Creme rinses are appHed to the hair after washing. Frequently used quaternaries in creme rinses are dodecyltrimethylammonium chloride [112-00-5] dimethyloctadecy1(pentaethoxy)ammonium chloride, benzyldimethyloctadecylammonium chloride [122-19-0] and dimethyldioctadecylammonium chloride...

Most of the early research work has mainly been focused on the nanocomposites of sihcone rubber filled with different clay modified by different intercalating agents [41, 125, 139, 141, 143, 171-173]. Based on the XRD studies in Figure 7.4, Burnside and Giannelis [141] concluded that the delaminated morphology is developed in silanol-terminated PDMS nanocomposites filled with 5 wt% of dimethyl ditallow ammonium bromide-modified Na -montmorillonite. On the contrary, no intercalation or delamination takes place in the benzyldimethyloctadecylammonium salt-modified bentonite and silanol-terminated PDMS nanocomposite. Hexadecyltrimethylammoium ions-modified lithium fluorohectorite (Cj FH) has also been used to prepare PDMS (average M. Wt 400,1750,4200 Da) nanocomposites [139]. 

Figure 7.4 X-ray diffraction patterns of PDMS nanocomposites containing various amounts of organosUicate. The top pattern corresponds to a hybrid prepared using 5 wt% of benzyldimethyloctadecylammonium (BDMO)-modified bentonite instead of the dimethyl ditallow ammonium bromide (SO 4682)-modified Na -montmorilloniteused in the other hybrids [141], Reprinted with permission from ACS.
