    摘要: A compound being a substituted benzyl derivative of polyalkylene polyamine and corresponding to the following formula: ##STR1## in which: n and m=2, 3 or 4, p=2 or 3, x=0, 1 or 2, R.sub.1 and R.sub.4, which may be identical or different, represent(i) a linear or branched C.sub.1 -C.sub.4 alkyl radical or(ii) a radical of the following formula: ##STR2## in which: Z.sub.1 represents OH or OR, Z.sub.2 and Z.sub.3 represent H, OH or OR, R being a linear or branched C.sub.1 -C.sub.8 alkyl radical,R.sub.2 and R.sub.3, which may be identical or different, represent H, a linear or branched C.sub.1 -C.sub.4 alkyl radical, a radical of formula (A) or a radical of the following formula (B): ##STR3## R'.sub.1, R'.sub.4 and R'.sub.5 represent H or a linear or branched C.sub.1 -C.sub.4 alkyl radical, and R.sub.5 represents a linear or branched C.sub.1 -C.sub.4 alkyl radical or a radical of formula (A),with the proviso that at least one of the radicals R.sub.1, R.sub.2, R.sub.3, R.sub.4 or R.sub.5 represents a radical of formula (A), and that when R.sub.1 and R.sub.4, being identical, represent a radical of formula (A), x being 0 or 1, then Z.sub.1 or Z.sub.1 and Z.sub.2, being identical, cannot represent OR, R being a C.sub.1 -C.sub.6 alkyl radical,and their salts and metal complexes.Use in cosmetic and pharmaceutical compositions in order to protect the body against oxidative stress.
