The present invention relates to a fragrance composition to be incorporated into the core of a core shell capsule comprising: I) 60-100% by weight of at least 5 fragrance compounds, 20-100% by weight of said fragrance compounds comprising at least 3 bulky molecules having a molecular weight of less than 325 atomic mass units, conforming to the following structures: a) molecules containing more than one ring, each ring having between 3 and 8 atoms of any of carbon, oxygen, nitrogen or sulfur in any ring and atoms being shared by any of the rings; b) molecules having at least two rings, each ring having between 3 and 8 atoms of any of carbon, oxygen, nitrogen or sulfur in which any rings share a common atom; c) molecules having at least two rings, each ring having between 3 and 8 atoms of any carbon, oxygen, nitrogen or sulfur in which any two rings share at least two adjacent common atoms; d) molecules containing a single alicyclic ring which contains at least 5 atoms, but no more than 8 atoms, of any of carbon, oxygen, nitrogen and sulfur in which at least one of the carbon atoms of the ring has two substituents, or a carbon atom alpha to the ring is tertiary carbon atom, or the ring has substituents on at least three of the atoms which make up the ring; e) molecules containing at least one macrocyclic ring, which is a ring having more greater than eight atoms of any of carbon, nitrogen oxygen or sulfur in the ring; f) molecules containing at least one substituted aromatic ring containing at least 5 atoms of any of carbon, oxygen, nitrogen or sulfur, but in which at least one substituents has a tertiary carbon in a position alpha or beta to the ring; g) molecules containing a substituted aromatic ring comprising at least 5 atoms with at least 3 substituents groups on the ring all of which must contain at least 2 atoms from among carbon, oxygen, nitrogen or sulfur; and II) 0-40% by weight of pro-fragrances, solvents, and other benefit agents which possess any of the structural features a) to g) but are not constrained by the molecular weight restrictions.
