A biphasic composition comprising: I. an aqueous phase comprising: a. anionic surfactant having; j) a first anionic surfactant comprising an anionic saccharide-based surfactant or an anionic saccharide-based surfactant, and a C10-C20 lactylate, a C10-C20 glycolate or both and with the proviso that when the lactylate, glycolate or both and saccharide-based surfactants are present, the first anionic surfactant is at least 40% by weight anionic saccharride-based surfactant based on total weight of the first anionic surfactant; ii) a second anionic surfactant comprising a furan-based anionic sulphate free surfactant; which comprises: A) a head group comprising Ai) a furan ring Aii) a sulphonate group directly attached to the furan ring; wherein the furan-based anionic sulphate free surfactant has the structure of Formula (I): Formula (I) where R is a hydrophobic alkyl tail group having a carbon chain length of 8 to 18, 18:1 and 18:2 where R groups of different chain lengths can be used in combination as a blend, preferably a blend of chain lengths of C12 and C14 and X is a counterion, selected from organic and inorganic counterions; B) an amide containing linker group; and C) a hydrophobic alkyl tail group having a carbon chain length of 8 to 18; viii) amphoteric surfactant, zwitterionic surfactant or both; ix) 5 to 17%, and preferably, 7 to 16%, and most preferably, 7.5 to 15% (or from 8 to 15% or from 9 to 14.5% or from 9.5 to 13.5%) by weight of solvent comprising from 83 to 100% by weight C3 to C10 diol based on total weight of the solvent; x) optionally a thickener; and xi) 8 to 40%, and preferably, from 10 to 35%, and most preferably, from 11 to 32% (or 12 to 31% or 12 to 30% or 12 to 29%) by weight water; and xii) from 0.0 to 8% by weight of a C8 to C18, and preferably, C10 to C16, and most preferably, C12 to C14 fatty acid, fatty alcohol, fatty amide or mixture thereof; and II. an oil phase comprising: at least 92.5%, and preferably, 93 to 100% and most preferably, from 94 to 100% by weight oil or from 94 to 99% or from 95 to 98% by weight oil or 100% by weight oil that is clear at a temperature from -21°C to 35°C, and preferably, from -20°C to 35°C, and most preferably, from -18°C to 35°C or from -17°C to 35°C or from -17 to 30°C or from -16 to 28°C wherein the aqueous phase has a pH greater than 5.7 to 8, and the biphasic composition comprises at least 3.3 to 9.5% by weight of the first anionic surfactant, and from 7.5 to 18.5%, and preferably, from 7.7 to 18%, and most preferably, from 8 to 18% or from 8.2 to 18% or from 11 to 18% or from 12 to 18% or from 13 to 18% total surfactant based on total weight of the biphasic composition and further wherein the aqueous phase and the oil phase each, independently, make up from 30 to 70% by weight of the biphasic composition. The biphasic wash composition with agitation yields a transient emulsion which is a wash composition that delivers lather and moisturization benefits even when comprising at least 30% by weight oil.
