A new approach for the explanation of the anomalous increase of the concentration fluctuations in dilute water-alcohol solutions is developed. This phenomenon is assumed to be connected with the peculiarities of clusrerization effects in a system approaching the pseudospinodal – the instability line for a system containing only the elementary clusters. It was proposed that the pseudospinodal separates the states of solution with different cluster structure. The pseudospinodal position is estimated. The behaviour of integral intensity of the molecular light scattering is described. To specify the fine details, experimental investigation of the molecular light scattering in water-glycerol solution was performed. The peculiarities of equilibrium and metastable crystallizations in this solution are considered.
