Transforming cosmetic composition into film, for use as face mask, involves mixing composition with at least one alginate salt, and mixing resulting mixture with calcium salt

摘要

The process of transforming cosmetic composition, containing at least one active agent, into film, comprises: (a) mixing a composition with at least one alginate salt (preferably in amount 0.5-4 wt.% per total wt. of initial composition); and (b) treating obtained mixture A with at least one calcium salt (preferably by spraying with aqueous solution of calcium salt). The process of transforming cosmetic composition, containing at least one active agent into film. The mixture A may additionally contain calcium ions inhibiting agent (CI), and/or xanthane and/or caroube (sic) gum (the latter in amount 0.05-1 wt.% per total wt. of composition). Initial composition (before transformation into film) is preferably free from calcium ions, has form of gel or emulsion, and has pH 5-9. Independent claims are also included for: (1) Cosmetic film containing at least one active substance and obtained as claimed; (2) face mask consisting of film as claimed; and (3) cosmetic kit, comprising at least one cosmetic composition, at least one alginate and at least one calcium salt, or at least one mixture A (of cosmetic composition and alginate) and at least one calcium salt, to be used in combination, simultaneously, separately or in layers in order to transform cosmetic composition into film, with optional calcium ions inhibiting agent CI present in cosmetic kit or incorporated into initial composition.
