Cosmetic composition comprises a non silicone polymer with at least two functional groups selected from a long list and dries to form a film with a defined Young's modulus. Cosmetic composition comprises a non silicone polymer with at least two functional groups selected from epoxy, anhydride, acid chloride, ethyleneimino, aldehyde, (hemi)acetal, (hemi)aminal, ketone, alpha -halo ketone, alpha -hydroxy ketone, lactone, thio lactone, isocyanate, thiocyanate, N-hydroxy succinimide ester, imide, imine, imidate, oxazoline, oxazolinium, oxazine, oxazinium, pyridyl thio, thiosulfate and groups of formula (I)-(III). A film formed by drying the composition at 20-24 deg C and 45-55% relative humidity has a Young's modulus of 1-100 MPa (exclusive), measured at 0.5 mm thickness under 20 mm/min traction. -OCO-A'-COCH3 (I) AX (II) ASO2X (III) A' = a bond or 1-5C alkylene X = halo, sulfato, mesyl, ethyl sulfonyl, tosyl, tri methylamino, OPO3R2 or CN R = H or 1-5C alkyl A = 1-22C alkylene, arylene or aralkylene, optionally interrupted by unsaturated rings and/or heteroatoms Independent claims are also included for: (1) an aerosol device comprising the above composition and a propellant; (2) a cosmetic treatment method comprising applying the above composition.
