Derivatives of terpene origin, surfactant and/or fragrant composition containing them and detergent formulation based on this composition

A compound of the following formula (I):

• ##STR14## in which:
• Z is a bicyclo›a.b.c!heptenyl or bicyclo›a.b.c!heptyl radical, wherein:
• a+b+c=5,
• a=2, 3 or
• b=2 or 1,
• c=0 or 1,
• said radical optionally being substituted by at least one C.sub.1 -C.sub.6 -alkyl, and comprising a skeleton of a formula selected from the group consisting of Z.sub.1, Z.sub.2, Z.sub.3, Z.sub.4, Z.sub.5, Z.sub.6, Z.sub.7, and a respective heptyl analog thereof without the double bond:
• ##STR15## wherein R.sup.2 and R.sup.3 are identical or different and are hydrogen or a linear or branched (cyclo)alkyl or (cyclo) alkenyl group;
• R.sup.4 and R.sup.5 are identical or different and are hydrogen or a linear or branched (cyclo) alkyl or (cyclo) alkenyl radical;
• R.sup.6 is hydrogen, SO.sub.3 M, OPO.sub.3 (M).sub.2, or --(CH.sub.2).sub.y --COOM, wherein y is from 1 to 6, or --(CH.sub.2).sub.z --SO.sub.3 M, wherein z is from 1 to 6;
• and M is H, Na, K, Li or N(R.sup.7).sub.4.sup.+, wherein R.sup.7 is H or a C.sub.1 -C.sub.22 -(cyclo)alkyl, which is optionally hydroxylated;
• m is 0 or 1;
• <
• p<20;
• and
• 1<q<200;
• with the proviso that when m is 0, at least one of R.sup.4 and R.sup.5 is other than hydrogen.
