Patent ID: 7943155

Claim:
A self-reversible reverse microlatex composition comprising: an oil phase; an aqueous phase; at least one water-in-oil (W/O) surfactant; at least one oil-in-water (O/W) surfactant; and a branched or a crosslinked polyelectrolyte being from about 15% to about 40% of the total weight of the composition, wherein said polyelectrolyte is a crosslinked homopolymer which consists of 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulphonic acid that is partially or totally salified, and the water-in-oil (W/ 0 ) surfactant and the oil-in-water (O/W) surfactant together as a mixture have a total Hydrophile Lipophile Balance (HLB) from 8.5 to about 11 to enable formation of a water in oil self-reversible reverse microlatex.
