Abstract
The present invention relates to a composition, in particular cosmetic, in the form of an oil-in-water emulsion, comprising a continuous aqueous phase and a dispersed oil phase in the form of drops (G1) and drops (G2), wherein the size of the drops (G1) is less than 500 μm and the size of the drops (G2) is greater than 500 μm.
Claims20
A composition in the form of an oil-in-water emulsion, comprising a continuous aqueous phase and a dispersed oil phase in the form of drops (G1) and (G2),
- wherein the drops (G1) comprise an oil phase and a shell formed of at least one anionic polymer (PA1) and at least one cationic polymer (PC1), wherein the size of the drops (G1) is less than 500 μm,
- wherein the drops (G2) comprise an oil phase and a shell, said shell being formed of at least one anionic polymer (PA2), identical to or different from (PA1), and at least one cationic polymer (PC2), identical or different from (PC1), wherein the size of the drops (G2) is greater than 500 μm,
- wherein the drops (G1) and (G2) are different in nature, in regard to the nature of the anionic and cationic polymers, or oils and/or additional compounds and/or active agents
- wherein the anionic polymers (PA1) and (PA2) are hydrophilic, and the cationic polymers (PC1) and (PC2) are liposoluble, and
- wherein the composition does not include a surfactant.
