Abstract: The present invention relates to a composition comprising, in at least one physiologically acceptable volatile medium: (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or a salt thereof; (c) at least one powder; and (d) at least one polyol, wherein the (c) powder is insoluble in the physiologically acceptable volatile medium. The composition can form a film including a DIC-gel and a powder wherein the distribution of the powder in the film can be more even or more uniform.

Abstract: The present invention relates to a composition comprising: (a) at least one particle. comprising at least one cationic polymer, at least one anionic polymer, and at least one non-polymeric acid having two or more pKa values or a salt thereof; (b) at least one oil; (c) at least one fatty acid; and (d) water. The composition according to the present invention is stable even when it comprises a relatively large amount of oil, such as up to 30% by weight relative to the total weight of the composition.
