Claims14
A dispersion containing a dispersed phase comprising droplets and a continuous aqueous phase, wherein the droplets comprise at least one fatty phase,
- wherein the fatty phase comprises at least one pigment in a content higher than 23.5 weight % relative to the weight of the fatty phase, and wherein the fatty phase also comprises at least one lipophilic gelling agent,
- wherein said lipophilic gelling agent is selected from the group consisting of:
- organic or mineral, polymeric or molecular lipophilic gelling agents, and mixtures thereof;
- and wherein the lipophilic gelling agent is not a polyorganosiloxane;
- wherein said mineral lipophilic gelling agent is selected from the group consisting of:
- hectorites modified by C10 to C22 ammonium chloride, hectorite modified by distearyl dimethyl ammonium chloride, hectorite modified by distearyl dimethyl ammonium chloride, benzalkonium and quaternium-18 bentonites, and clays modified by stearyldimethylbenzoylammonium chloride, and
- wherein the droplets have a diameter larger than 500 μm and represent a volume equal to or greater than 60% of the total volume of the dispersed phase, and/or at least 60% of the droplets have a mean diameter larger than 500 μm,
- wherein the droplets also comprise a shell, said shell comprising at least one anionic polymer and at least one cationic polymer, and
- wherein the dispersion does not comprises a surfactant.
