Abstract
An addition polymer of a water insoluble soft monomer, a water soluble anionic monomer and, optionally, a water soluble nonionic monomer and water insoluble hard monomer is neutralized to at least about 75%, and formed into a sheet. A laundry care additive, as a bleach, may be stored between a pair of opposed heat sealed sheets to provide a laundry care product adapted to be introduced into a laundry wash.
Claims7
A laundry care product which comprises a particulate laundry care additive carried in a water soluble sheet which comprises a self-supporting film of an addition polymer formed of:
- (a) From about 40 to 95% by weight of a water insoluble soft monomer;
- (b) From about 3 to 15% by weight of a water soluble anionic monomer;
- (c) From about 0 to 25% by weight of a water soluble non-anionic monomer;
- (d) From about 0 to 40% by weight of a water insoluble hard monomer
- wherein said addition polymer is at least about 75% neutralized with a group 1A metal base or a group 1A metal basic salt.
