The present invention relates to a foaming composition comprising: (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or salt thereof; (c) at least one oil; and (d) at least one physiologically acceptable volatile medium, wherein the amount of the (c) oil(s) in the composition is 10% by weight or more, preferably 15% by weight or more, and more preferably 20% by weight or more, relative to the total weight of the composition. The composition according to the present invention can form a foam which is stable over time.

Foaming composition comprising oil

The present invention relates to a composition, preferably a cosmetic composition, and more preferably a skin cosmetic composition, comprising: (a) at least one complex, comprising at least one cationic polymer and at least one anionic polymer, at least one cationic polymer and at least one amphoteric polymer, at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, and at least one non-polymeric acid having two or more pKa values or salt(s) thereof or at least one non-polymeric base having two or more pKb values or salt(s) thereof; (b) at least one oil; and (c) water, wherein the cationic polymer comprises at least one cationic cellulose polymer with at least one fatty chain comprising at least 10 carbon atoms, and if the (a) complex comprises at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, the (a) complex further comprises at least one cationic cellulose polymer with at least one fatty chain comprising at least 10 carbon atoms. The composition according to the present invention is stable even at an elevated temperature, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as moisturizing due to the oil(s).

Composition comprising oil and polyion complex including cellulose-based cationic polymer with at least one fatty chain

The present invention relates to a composition in the form of an O/W emulsion, comprising: (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or salt thereof; (c) at least one oil; and (d) water, wherein the amount of the (c) oil(s) in the composition is 50% by weight or more, preferably 60% by weight or more, and more preferably 70% by weight or more, relative to the total weight of the composition. The composition in the form of an O/W emulsion according to the present invention is stable. Also, a composition in the form of an O/W/O emulsion can be prepared by the composition in the form of an O/W emulsion according to the present invention.

Emulsions with a high internal oil phase

The present invention relates to a composition comprising (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or salt thereof; and (c) at least one physiologically acceptable volatile medium, wherein the composition optionally comprises surfactant(s) in an amount of 1% by weight or less, preferably 0.5% by weight or less, and more preferably 0.3% by weight or less, relative to the total weight of the composition. The composition according to the present invention can provide a self-healing or self-repairing film.
