Abstract: 1) A fabric softening composition comprising: i) a liquid or soft solid derivative of a cyclic polyol (CPE) or of a reduced saccharide (RSE) resulting from 35 to 100% of the hydroxyl groups in the cyclic polyol or reduced saccharide being esterified or etherified, the derivate (CPE or RSE) having at least 2 or more of ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain or mixtures thereof, and containing at least 35% tri or higher esters; ii) a deposition aid. 2) A fabric softening composition according to claim 1 wherein the CPE or RSE results from a cyclic polyol or a reduced saccharide having 40-70% of the hydroxyl groups esterified and/or etherified. 3) A fabric softening composition according to either of claims 1 or 2 wherein the CPE or RSE results from a cyclic polyol or reduced saccharide having 4 or more hydroxyl groups etherified or esterified. 4) A fabric softening composition according to any preceeding claim in which CPE or RSE is derived from a monosaccharide or disaccharide. 5) A fabric softening composition according to any one of the preceeding claims in which the CPE is a saccharide polyester, a saccharide polyether or a saccharide polyester/polyether. 6) A fabric softening composition according to any preceeding claim wherein the CPE is a selected from sucrose pentalaurate, sucrose tetraoleate, sucrose pentaerucate and sucrose tetraerucate. 7) A fabric softening composition according to any preceding claim in which the ester or ether groups of the CPE or RSE are independently of one another attached to a C8 to C22 alkyl or alkenyl chain or a C2 to C8 chain and in which the ratio of C8 to C22 groups to C2-C8 is from 5:3 to 3:5. 8) A fabric softening composition according to any preceding claim in which the deposition aid is selected from a cationic surfactant, a nonionic surfactant, an anionic surfactant, a polymeric deposition aid, a fabric softening compound or mixtures thereof. 9) A fabric softening composition according to any preceding claim in which the fabric softening compound has a solubility of less than 1 x 10-3 wt% in demineralised water at 20 degree C. 10) A fabric softening composition according to claim 9 in which the fabric softening compound is a quaternary ammonium compound. 11) A fabric softening composition according to any preceding claim in which the ratio of CPE or RSE to deposition aid is within the range from 1:10 to 15:1. 12) A fabric softening composition according to any preceding claim which is in liquid form or emulsion form. 13) A fabric softening composition according to claim which further comprises a viscosity control agent. 14) Use of a CPE or RSE as defined in any of the preceeding claims within a fabric softening composition as a fabric softening aid that does not decrease the fabrics absorbency. 15) A liquid or soft solid fatty acid ester of glucose having a solid:liquid ratio of between 50:50 and 0:100 as measured by T2 relaxation time NMR at 20 degree C, the ester groups comprising a mixture of C2-C22 alkyl or alkenyl chains and resulting from a cyclic polyol having 35-100% of the hydroxyl groups esterified. 16) A fatty acid ester of glucose according to claim 15, the ester groups consisting essentially of a C2 C8 alkyl chain and a C8 to C12 straight alkyl chain, the molar ratio of C2 alkyl chain to C8 to C12 straight alkyl chain being from 2:1 to 1:2. 17) A fabric softening composition which comprises: i) a liquid or soft solid derivative of a cyclic polyol (CPE) or of a reduced saccharide (RSE) resulting from 35 to 100% of the hydroxyl groups in the cyclic polyol or reduced saccharide being esterified or etherified, the derivate (CPE or RSE) having at least 2 or more of ester or ether groups independently attached to a C8-C22alkyl or alkenyl chain or mixtures thereof, and containing at least 35% tri or higher esters, and resulting from disaccharide; ii) a deposition aid.
