in which
A is —O— or —NH;
R is a C1-C22 alkyl group, a C2-C22 alkenyl group, a C2-C22 alkynyl group, a C3-C22 cycloalkyl group or a C3-C22 cycloalkenyl group, said groups possibly being interrupted with one or more O; and
b) at least one oily phase comprising at least one amide selected from the group of amides of formula (4)

OG Complex Work Unit Drawing
in which:
the R1 radical represents a linear or branched C1-C4 alkyl radical; a linear or branched C2-C4 alkenyl radical, or an aryl radical”, limits included;
the R2, R3 and R4 radicals, which may be identical or different, represent saturated or unsaturated, aliphatic, cycloaliphatic or cyclic, optionally functionalized, monovalent hydrocarbon-based radicals containing from 1 to 30 carbon atoms, limits included;
k is 0 or 1;
i is an integer from 0 to 2;
j is 0 or 1;
with the proviso that:
when j=1 then k is 0 and
R1 represents a linear or branched C1-C4 alkyl radical; a linear or branched C2-C4 alkenyl radical, or an aryl radical;
R2 represent a hydrogen atom or a linear or branched C1-C6 alkyl group;
R3 represents a hydrogen atom or a linear or branched C1-C6 alkyl group;
R4 represents a linear or branched C1-C10 alkyl radical, a linear or branched C2-C10 alkenyl radical or a sterol residue;
or with the proviso that:
when j=0, then i=0 and k=1 and R1 represents an unsaturated cyclic hydrocarbon-based radical, which is optionally substituted.
