PROBLEM TO BE SOLVED: To provide an opacifying bath preparation enabling the white inorganic pigment therein to readily and homogeneously be dispersed in the hot water in a bathtub by shaking the bath preparation by hand when to be used and also enabling the resultant homogeneously dispersed condition to stably be kept for a long time. SOLUTION: This opacifying bath preparation is obtained by including 0.5-70 wt.% of the while inorganic pigment surface-treated with 0.1-50 wt.% of a silane coupling agent of the general formula (1): [R1 O(CH2 CHO)n (CH2 )k ]x Si(OCm H2m+1 )y (where, n and k are each an integer of >=1; m is an integer of 1-3; x and y are each an integer of 1-3, and x+y=4; and R1 and R2 are each H or a 1-10C hydrocarbon group).
