Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
Arrangement for removal of unwanted hair, comprising a plastic sheet material of predetermined shape and size having a pressure sensitive adhesive composition comprising a high molecular weight polymer selected from the group consisting of polymers of natural rubber, butyl rubber, butadiene styrene, block styrene, ethylene vinyl acetate, vinyl acetate, ethyl cellulose and natural waxes in an amount of about 9-10% by weight, a tackifier selected from the group consisting of terpenes, rosin derivatives, coumarone indene, hydrocarbon resins and terpene phenolics in an amount of about 65-68.5% by weight, a softener selected from the group consisting of mineral oil, liquid rosin derivatives, lanolin dibutyl phthalate, dioctyl phthalate and tricresyl phosphate in an amount of about 21.5-25% by weight, and an antioxidant selected from the group consisting of 2,2-methylene-bis(4-methyl-6-tertiary butyl)-phenol, 1,3,5-triethyl-2,4,6-tris-(3,5-ditertiary butyl-4-hydroxy benzyl)-benzene, butylated hydroxy anisole and butylated hydroxy toluol in an amount of about 0.5% by weight applied to a face thereof, said composition adhering firmly to hair but not to skin so that when the same is applied to an area of the body from which it is desired to remove unwanted hair, and subsequently peeled away therefrom, only the unwanted hair is removed.
