Organosilicon compounds of formula (I) and/or (II) are new. R = methyl or ethyl; R' = 9-30C alkyl or alkenyl, aryl, aralkyl, 2-30C alkylether, 2-30C alkyl-polyether (all optionally branched) or R'''3Si; R'' = optionally unsaturated 1-30C aliphatic, aromatic or aliphatic/aromatic hydrocarbylene; R''' = 1-30C alkyl or alkenyl, aralkyl or aryl; X = NH3-n with n = 1, 2 or 3 and m = 1, or OCOR' with n = m = 1, or SH with n = m = 1, or S with n = 2 and m = 1-10, or SCOR' with n = m = 1, or H with n = m = 1.
