摘要： The present invention relates to a process for the manufacturing of 3-phenylpropan-1-ol, from nature derived starting material, wherein said nature derived starting material comprises not less than 80 wt.% of cinnamaldehyde. In another aspect, the present invention relates to the process, which further comprises the steps: a) conversion of cinnamaldehyde as starting material to 3-phenylpropan-1-ol by a catalytic hydrogenation; b) optional purification of the 3-phenylpropan-1-ol by alkaline water extraction; c) distillation of 3-phenylpropan-1-ol. In a third aspect the present invention relates to use of 3-phenylpropan-1-ol obtained by the process of the invention in perfumes and/or personal care and/or cleaning products.
