Composition and method for preparing novel cationic thickners

A self reversible inverted latex comprising;

• an oily phase;
• an aqueous phase;
• at least one water-in-oil emulsifying agent;
• and
• at least one oil-in-water emulsifying agent comprising 25% to 70% by weight of a crosslinked cationic copolymer, wherein
• the crosslinked cationic compolymer comprises:
• from about 55% to about 95% of the monomeric units being acrylamide;
• from about 5% to about 35% of the monomeric units being at least one cationic monomer;
• and
• from about 0.1% to about 5% of the monomeric units being at least one nonionic surfactant monomer of the formula (I):
• A-C(═O)—O—[(CH2—CH(R1)—O]n—R (I),
• wherein:
• (i) n is from 1 to 10,
• (ii) A is a vinyl radical,
• (iii) R1 comprises at least one component selected from the group consisting of a hydrogen atom, a methyl radical, and an ethyl radical, and
• (iv) R is a lauryl radical.
• wherein said percentages are expressed in terms of monomeric units.
