Mascara containing fiber components
View Patent ↗The invention relates to a mascara containing fibre components and a method for producing the same. Said mascara contains (in % by weight) 0.1-10 of at least one oil-soluble or oil-dispersible polymer or copolymer, 0.3-10 of a natural or synthetic fibre with an average length of between 3 and 6 mm, 10-30 of a natural or synthetic wax which hardens at 25° C., 1-10 of a synthetic wax which is liquid at 18° C. and above, 0.5-10 of inorganic pigments, organic colourants and mixtures thereof, 40-80 water and cosmetic auxiliaries, active agents and mixtures thereof making up the remainder up to 100% by weight, wherein said mascara does not contain any water-soluble or water-dispersible hydrophilic polymers, film-forming agents, thickeners or clays. The fibres are separated very well and the mascara shows a very good balance between its adhesive properties and the brittleness of the mascara film.
1. A method for producing a mascara containing a fiber component comprising
(a) mixing an oil phase comprising waxes, oil, pigment and at least one oil-soluble or oil-dispersible polymer or copolymer with an aqueous phase at 65-78° C. until complete emulsification is achieved, and
(b) mixing the emulsion of step (a) at 50-70° C. by stirring with a homogeneous, alcohol-free mixture of fiber and liquid synthetic wax, liquid polyethylene or mixtures thereof, which has been prepared at between 18 and 25° C.
2. The method according to claim 1 , wherein said at least one oil-soluble or oil-dispersible polymer or copolymer is a copolymer of maleic anhydride, an isopropylmaleate and olefin monomer having between 30 and 45 carbon atoms; a copolymer of vinylpyrrolidone and long-chain alpha-olefins; a copolymer of adipic acid with fumaric acid, phthalic acid and tricyclodecane dimethiconol; a copolymer of adipic acid, cyclohexanedimethanol, maleic anhydride, neopentyl glycol and trimellitic anhydride monomer; a copolymer of adipic acid and a PPG-10 monomer; polyethylene; butadiene/isoprene copolymers; copolymers of ethyl esters or butyl esters of PVM/MA copolymers; Tricontanyl PVP; C20-40 Acid (and) Polyethylene; PVP/Eicosene; Bis-Diglyceryl Polyacyladipate-1; Polyvinyl Octadecyl Ether; or a mixture thereof.
3. The method according to claim 2 , wherein said at least one oil-soluble or oil-dispersible polymer or copolymer is Tricontanyl PVP, C20-40 Acid (and) Polyethylene, PVP/Eicosene or a mixture thereof.
4. The method according to claim 1 , wherein said fiber is poly-ester, rayon, nylon, cotton, Teflon or spandex.
5. The method according to claim 1 , wherein the fiber has an average length of between 4 and 4.5 mm.
6. The method according to claim 1 , wherein said oil phase wax is a natural or synthetic wax which is solid at 25° C. and below.
7. The method according to claim 4 , wherein said fiber is spandex.
8. The method according to claim 6 , wherein said oil phase wax is beeswax, ozokerite, carnauba wax, candelilla wax, wool wax, hard paraffin, ceresin, silicone wax, a polyethylene glycol wax or a polyethylene glycol glycol ester wax.
9. A method according to claim 1 wherein said oil phase comprises 0.5 to 7% by weight of at least one oil-soluble or oil-dispersible polymer or copolymer and 0.5 to 10% by weight of an inorganic pigment.
10. A method according to claim 1 , wherein said emulsion of step (a) is mixed with 0.3 to 10% by weight of a natural or synthetic fiber and 1 to 10% by weight of a liquid synthetic wax.
11. The method of claim 1 , wherein no water-soluble or water-dispersible hydrophilic polymers, film-forming agents, thickeners or clays are added to the mascara.
12. A method according to claim 1 , wherein the homogeneous, alcohol-free mixture of fiber and liquid synthetic wax, liquid polyethylene or a mixture thereof, has been prepared at between 18 and 25° C. and stirring at 12-20 rpm before incorporation into the emulsion of step (a).
