  • Dryer-activated fabric conditioning and antistatic compositions with improved perfume longevity
    Patent number: 5559088
    Abstract: The present invention relates to dryer-activated fabric softening compositions comprising: (A) fabric softening compounds; (B) a non-allylic perfume alcohol ester; and (C) optionally, (1) a carboxylic acid salt of a tertiary amine and/or a tertiary amine ester; and (2) a nonionic softener; wherein, preferably, the Iodine Value of the total number of fatty acyl groups present in (A), (C)(1), and (C)(2) is from about 3 to about 60. These compositions exhibit good antistatic properties as well as improved delivery from a substrate.
