Abstract
The present invention is directed to bimodal polymer compositions and personal care fixatives containing bimodal polymer compositions. The present invention includes a bimodal polymer composition having a first polymer with anionic character and a second polymer with cationic character and wherein the polymers form an interpenetrating polymer network. In one embodiment, the present invention also includes personal care fixatives (e.g., health care, hygiene or cosmetic compositions) containing the bimodal polymer composition. The present invention also includes methods for forming bimodal polymer compositions.
Claims14
A method for forming a bimodal polymer composition, comprising the step of polymerizing monomers to form a first polymer, having a first ionic character, in the presence of a second polymer, having a second ionic character, and further in the presence of aqueous ammonia,
- wherein said first polymer has a molecular weight ranging from about 1,000 daltons to about 1,000,000 daltons,
- wherein said second polymer has a molecular weight ranging from about 1,000 daltons to about 1,000,000 daltons, and
- wherein the first and the second polymers form an interpenetrating polymer network.
