Acidic liquid fabric care compositions

A liquid fabric care composition comprising:

• from about 10% to about 50%, by weight of the liquid fabric care composition, of citric acid and/or a salt thereof;
• from about 0.01% to about 20% of fragrance material, wherein the liquid fabric care composition is substantially free of vinegar and acetic acid;
• wherein the fragrance material comprises first aldehydic perfume raw materials, wherein the first aldehydic perfume raw materials are characterized by at least one of the following structures:
• R1—C(R2)(R3)—C(R4)(R5)—CHO, a)
• wherein R2, R3, R4, and R5 are independently selected from hydrogen or a hydrocarbon moiety, wherein the hydrocarbon moiety may be substituted or unsubstituted, with the proviso that at least one of R2, R3, R4, or R5 is a hydrocarbon moiety;
• R1-C(R2)=C(R4)-CHO, b)
• wherein R2 and R4 are independently selected from hydrogen or a hydrocarbon moiety, wherein the hydrocarbon moiety may be substituted or unsubstituted;
• R1—Ar—CHO, c)
• wherein Ar is a substituted or unsubstituted aryl ring;
• wherein for each of the structures according to a), b), and c), each R1 is independently selected from H, a substituted hydrocarbon moiety, or an unsubstituted hydrocarbon moiety;
• from about 30% to about 90%, by weight of the liquid fabric care composition, of water;
• wherein the composition comprises less than 5%, by weight of the liquid fabric care composition, of a material selected from the group consisting of detersive surfactant, bleaching systems, fabric softening materials, and mixtures thereof;
• wherein the liquid fabric care composition is characterized by a neat pH of from about 2 to about 6.
