1. A liquid composition comprising a microcapsule, said microcapsule comprising an aldehyde-containing resin, wherein said microcapsule is a core in shell microcapsule comprising perfume raw materials; from about 0.0001% to about 1% by weight of said composition, of a non-sulfur-based formaldehyde scavenger, wherein said non-sulfur-based formaldehyde scavenger is urea; from about 0.001% to about 2.0% by weight of said composition, of a sulfur-based formaldehyde scavenger, wherein said sulfur-based formaldehyde scavenger is an alkali metal bisulfite; wherein said non-sulfur-based formaldehyde scavenger and said sulfur-based formaldehyde scavenger has a weight ratio of from 1:1 to 5:1; wherein said formaldehyde scavengers react with formaldehyde to achieve more than about 60% reaction completeness in about 15 minutes time at pH 8 and at about 21° C.; wherein said composition comprises anionic surfactant, and wherein said composition further comprises from 10% to 95%, by weight of the composition, of a solvent system, where the solvent system comprises water and C1-C4 alkanolamine. 2. The liquid composition according to claim 1, wherein said composition comprises a pre-made slurry which comprises said microcapsule and non-sulfur based formaldehyde scavenger. 3. The composition according to claim 1, wherein said microcapsule comprises microcapsule wall material having a ratio, by weight, of said sulfur-based formaldehyde scavenger to said microcapsule wall material of from about 0.05:1 to about 10:1. 4. The composition according to claim 1, wherein said microcapsule comprises microcapsule wall material having a ratio, by weight, of said sulfur-based formaldehyde scavenger to said microcapsule wall material of from about 0.1:1 to about 6:1. 5. The composition according to claim 1, wherein said microcapsule further comprises a substance selected from the group consisting of silicone oils, waxes, hydrocarbons, higher fatty acids, essential oils, lipids, skin coolants, vitamins, sunscreens, antioxidants, glycerine, catalysts, bleach particles, silicon dioxide particles, malodor reducing agents, dyes, brighteners, antibacterial actives, antiperspirant actives, cationic polymers and mixtures thereof. 6. The composition according to claim 1, wherein the composition further comprises blue dye. 7. A process of preparing a composition according to claim 1 comprising the steps of: i) preparing a slurry of microcapsules comprising the aldehyde-containing resin and the non-sulfur-based formaldehyde scavenger wherein said microcapsules are core in shell microcapsules comprising perfume raw materials;and thenii) adding said slurry to the sulfur-based formaldehyde scavenger and the solvent system.
