Abstract

1,202,796. Compacted polyester powder. IMPERIAL CHEMICAL INDUSTRIES Ltd. 18 March, 1969 [1 April, 1966], No. 15541/68. Heading C3R. [Also in Division A5] The invention comprises a compacted aggregate of finely divided linear polyester particles. Specified polyesters are polyethylene iso-, ortho- and tere-phthalate and copolyesters or mixtures thereof. Specified particle size is 1-10 microns. The particles may be prepared by precipitation of the polyester from a solution in, for example, propylene carbonate and may be compacted using a plate press or a rotating platform type press. The particles may be perfume-laden for use as a cosmetic and may be mixed with, for example, talc, zinc stearate, starch, chalk, magnesium carbonate, kaolin, iron oxides, zinc and magnesium salts of fatty acids, titanium dioxide, zinc oxide or magnesium oxide.
