Abstract: The present invention relates to a method for preparing capsules comprising a liquid core, a stiffened intermediate envelope and a gelled external envelope, comprising a step of forming a multi-component liquid drop, a gelification step and a stiffening step. The present invention also relates to a method for preparing capsules comprising a liquid core and a stiffened envelope, comprising a step of forming a multi-component liquid drop, a gelification step, a stiffening step and a depolymerizing step.

Abstract: A kit comprising two separate compositions (A) and (B). Composition (A) is an aqueous gel with a viscosity of less than 11 Pa·s and contains at least one capsule including: a liquid core with at least one active ingredient and a gelled envelope totally encapsulating the liquid core. The gelled envelope includes at least one polyelectrolyte in the gelled state. Composition (B) includes a depolymerizing agent.

Abstract: This method includes the provision of a first fluid (36) including the first phase and a first precursor polymer of the coacervate contained in the first phase, and the formation of drops of the first fluid (36) in a second fluid (40) intended to form the second phase (16). It includes the steps of introducing a second precursor polymer of the coacervate into the second fluid (40) and, during the formation of each drop (12), or once each drop (12) has been formed, for generating the coacervate layer by interaction between the first precursor polymer and the second precursor polymer at the interface between the first phase (14) and the second phase (16).
