Claims13
A composition comprising:
- (a) from about 0.1% to about 30%, by weight of the total composition, of a polyurethane material having a Tg of from about −50° C. to about 150° C., said polyurethane material comprising a material having Formula I below:
- wherein:
- y is 1-200
- R1 is selected from 4,4′-diphenylmethane, benzene, carbodiimide-modified 4,4′-diphenylmethane, and hexamethylene;
- R2 is selected from the moiety resulting from removing the hydroxyl groups from polypropylene glycol, the moiety resulting from removing the hydroxyl groups from polyethylene glycol, the moiety resulting from removing the hydroxyl groups from 1,4-butane glycol adipate, 1,4-butane, 1,3-propane, ethane, the moiety resulting from removing the hydroxyl groups from 4,4′-dihydroxy biphenyl, and the moiety resulting from removing the hydroxyl groups from 2,2′-dimethylolpropanic acid;
- R3, R4, R5 and R6 are independently selected from silicones, polyethylene, polypropylene, fatty esters, polyamines, polyacrylates, carboxylic acids, and polycarboxylic acids;
- and
- R7 and R8 are independently selected from aryl, heteroaryl, or alkyl groups;
- (b) a cross-linking agent, said crosslinking agent being present in a ratio of polyurethane to crosslinking agent of from about 100:1 to about 1:2, said ratio of polyurethane to crosslinking agent calculated by weight;
- and
- (c) a catalyst, said catalyst being present in a ratio of crosslinking agent to catalyst of from about 100:1 to about 1:5, said ratio of crosslinking agent to catalyst calculated by weight;
- the balance of said composition being a carrier, and
- said composition being a finished consumer product.
