                            A self-reversible reverse latex, and its use as a thickener. The self-reversible reverse latex includes: 50%-70% of a cross-linked polyelectrolyte obtained by the polymerization of a monomer of formula (I), with R1 being 8 to 20 carbon atoms and 1≦n≦30 for a neutral monomer, and a monomer having an acid function; 4%-10% of a water-in-oil emulsifier; 1%-10% of an oil-in-water emulsifier including a surface-active composition (C); 15%-45% oil; and 0%-5% water. Composition (C) is 10%-50% composition (C
II
) and 50%-90% composition (C
III
). Composition (C
II
) is 60%-100% of a composition of formula (II), with R2 being a 12 carbon alkyl, T

, T
2
, and T
3
being H or a (—CH

-0-)
mi
—H radical with 0≦mi≦10 and 0<Σmi≦10. Composition (C
III
) is 60%-100% of a compound of formula (III) or mixtures of (III) and (IV), with R2 being as defined previously.
