Conclusions:
The water solubility determination of test item 1'-acetonaphthone (CAS No. 941-98-0) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of (1'-acetonaphthone of 941-98-0 )in water was determine to be 87.677 mg/L at 25°C.
Thus the 1'-acetonaphthone is considered to be slightly soluble in water.
Executive summary:

The water solubility determination of test item 1'-acetonaphthone (CAS No. 941-98-0) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of (1'-acetonaphthone of 941-98-0 )in water was determine to be 87.677 mg/L at 25°C.

Thus the 1'-acetonaphthone is considered to be slightly soluble in water.
