Abstract
A self-reversible reverse microlatex composition comprising an oil phase, an aqueous phase, a water-in-oil surfactant(s), a oil-in-water surfactant(s) and 15% to 40% by weight by weight of a branched or crosslinked polyelectrolyte. The polyelectrolyte is based on a monomer containing a strong or weak acid function, which is partially or totally salified, a copolymer of at least one monomer containing a strong acid function and at least one monomer containing a weak acid function or at least one neutral monomer, a copolymer of at least one monomer containing a weak acid function and at least one neutral monomer, or a copolymer of at least one monomer containing a strong acid function, a monomer containing at least one weak acid function and at least one neutral monomer. The surfactants have a total HLB number of 8.5 to 11. Uses in cosmetics and as an industrial emulsifier and/or thickener.
