<p>1,214,693. Aqueous emulsion floor polishes. FMC CORP. 24 April, 1968 [27 April, 1967], No. 19268/68. Heading C3P. An aqueous emulsion floor polish composition comprise., in its solids content, a major proportion by weight of a water-insoluble thermoplastic polymer, other than a waxy material, and a waxy material which is a wax or emulsifiable polyethylene, a minor proportion by weight of an ammonia-soluble thermoplastic levelling resin, and from “ to 2% by weight of a levelling agent, which is at least one carbamate having the general formula in which R 1 is an unsubstituted C 6-10 alkyl radical or mixtures thereof and R 2 and R 3 are hydrogen, unsubstituted C 1-4 alkyl radicals or monohydroxy substituted C 1-2 alkyl radicals. The levelling agent may be 2-ethylhexyl carbamate, 2 - ethylhexyl N - methylcarbamate, 2 - ethylhexyl N,N - dimethylcarbamate, nhexyl carbamate, or mixed hexyl-decyl carbamates, iso-octyl carbamates, iso-octyl N- methylcarbamates, octyl - decyl carbamates, octyl-decyl N-methylcarbamates or decyl carbamates. The water-insoluble polymer may be polystyrene blended with shellac, a polyacrylate, or copolymers of an acrylate or acrylic acid with acrylonitrile or styrene respectively. The ammonic-soluble resin may be partially esterified modified rosin and styrene/maleic anhydride copolymers. The polishes may also contain diethylene glycol (mono-ethyl or -methyl) ether, ester and microcrystalline waxes, oleic acid, potassium hydroxide and morpholine.</p> |
