Mascara compositions containing at least two acrylate film formers

Abstract

Disclosed are mascara compositions containing a first acrylates copolymer having a relatively low glass transition temperature (Tg) which is less than about 0° C., a second acrylates copolymer having a relatively high glass transition temperature which is between about 0° C. and less than about 60° C., wherein a mixture of the first and second acrylates copolymers has a Tg less than about 20° C., and a solvent. Also disclosed are methods for making the mascara and applying them to keratinous tissue such as eyelashes in order to enhance their appearance.

       3 . The mascara composition of  claim 1 , wherein said first acrylates copolymer comprises an acrylates copolymer having a Tg of about −16° C. 
   
   
       4 . The mascara composition of  claim 1 , wherein said first acrylates copolymer comprises an acrylates/ethylhexyl acrylates copolymer. 
   
   
       5 . The mascara composition of  claim 1 , wherein said first acrylates copolymer comprises an acrylates/ammonium methacrylates copolymer. 
   
   
       6 . The mascara composition of  claim 1 , wherein said second acrylates copolymer comprises a styrene/acrylates copolymer having a Tg of about 35° C. 
   
   
       7 . The mascara composition of  claim 1 , wherein said second acrylates copolymer comprises a styrene/acrylates/ammonium methacrylates copolymer. 
   
   
       8 . The mascara composition of  claim 1 , wherein said second acrylates copolymer comprises an acrylates/dimethylaminoethylmethacrylates copolymer. 
   
   
       9 . The mascara composition of  claim 1 , wherein said second acrylates copolymer comprises a styrene/acrylates copolymer having a Tg of about 5° C. 
   
   
       10 . The mascara composition of  claim 1 , wherein said second acrylates copolymer comprises a polyurethane/polyethylene glycol copolymer. 
   
   
       11 . The mascara composition of  claim 1 , wherein said first acrylates copolymer comprises an acrylates copolymer having a Tg of about −16° C., and wherein said second acrylates copolymer comprises a styrene/acrylates copolymer having a Tg of about 5° C. 
   
   
       12 . The mascara composition of  claim 1 , wherein said first and second acrylates copolymers are present in a total amount of about 10% to about 30% on a non-dry weight basis, based on total weight of said mascara composition. 
   
   
       13 . The mascara composition of  claim 1 , wherein said solvent comprises water, and wherein said composition further comprises an emulsifier. 
   
   
       14 . The mascara composition of  claim 1 , wherein said solvent comprises a non-aqueous solvent. 
   
   
       15 . The mascara composition of  claim 14 , wherein said non-aqueous solvent comprises isododecane or petroleum distillate. 
   
   
       16 . The mascara composition of  claim 1 , further comprising a colorant. 
   
   
       17 . The mascara composition of  claim 1 , further comprising fibers. 
   
   
       18 . The mascara composition of  claim 1 , further comprising a wax. 
   
   
       19 . A package, comprising a container having disposed therein the mascara of  claim 1 , and optionally an applicator for applying the mascara composition to eye lashes. 
   
   
       20 . A method of preparing a mascara composition, comprising mixing together a first acrylates copolymer having a glass transition temperature (Tg) less than about 0° C., a second acrylates copolymer having a glass transition temperature between about 0° C. and about 60° C., wherein a mixture of said first and second acrylates copolymers has a Tg less than about 20° C., and a solvent. 
   
   
       21 . A method of making up or enhancing the appearance of eye lashes, comprising applying to eye lashes a mascara composition comprising a first acrylates copolymer having a glass transition temperature (Tg) less than about 0° C., a second acrylates copolymer having a glass transition temperature between about 0° C. and about 60° C., wherein a mixture of said first and second acrylates copolymers has a Tg less than about 20° C., and a solvent.
