A barrier composition which is injection mouldable and able to be made into a transparent film or incorporated (by co-extrusion and / or lamination) into multi-layer film products, the composition on dry basis: a) from 45 to 90% by weight of a starch and / or a modified starch selected from starches modified by reaction with a hydroxyl alkyl group, an acetate or a dicarboxylic acid anhydride or a grafting polymer; b) from 4 to 12% by weight of a water soluble polymer selected from polyvinyl alcohol, polyvinylacetate, and copolymers of ethylene and vinylalcohol which have a melting point compatible with the molten state of the starch components c) from 5 to 45% by weight of a non-crystallising mixture of sorbitol and at least one other plasticizer selected from glycerol, maltitol, xylitol, mannitol, glycerol trioleate, epoxidised linseed or soybean oil, tributyl citrate, acetyl tri-ethyl citrate, glyceryl triacetate, 2,2,4-trimethyl-1,3-pentanediol diisobutyrate; polyethylene oxide or polyethylene glycol; d) from 0.3 to 2.5% by weight of a C12-22 fatty acid or salt; e) from 0.25% to 3% of an emulsifier system having a hydrophilic lipophilic balance value between 2 and 10. The barrier film may be co-injection moulded with polyethylene terephthalate (PET) or polylactic acid (PLA) for blow moulding into beverage bottles, with polyethylene (PE) or polypropylene (PP) or biodegradable polymers for high gas-barrier containers or closures, or may be co-extruded with polyethylene, polypropylene or polylactic acid for thin film packaging applications or for blow-moulded containers.

The invention relates to chewable gum base compositions, to chewing gums containing them, and to processes for preparing them. The gum base compositions comprise (a) a polyvinyl acetate matrix, in which the polyvinyl acetate is in the form of a continuous phase, and (b) casein, a modified casein, or both casein and a modified casein, wherein particles of casein and / or modified casein are dispersed throughout the polyvinyl acetate matrix.In preferred embodiments the gum base compositions also contain polyglycerol polyricinoleate, mono- and di-glycerides esterified with mono-acetyl and di-acetyl tartaric acid, acetylated monoglycerides, lecithin and sodium or calcium stearoyl-2-lactylate. Chewing gums of the present invention contain a chewable gum base as described above, in combination with one or more sweeteners and / or flavouring agents, and preferably also glycerol triacetate and stearic acid.

Described are trimethylcyclohexenylcyclopropyl ketones having the structure: wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond, uses thereof in augmenting, enhancing or imparting aromas in or to perfume compositions, colognes and perfumed articles, and mixtures of same with 3-methyl-1-phenylpentanol-5 and / or butanoylcyclohexane derivatives and / or acetic or propionic acid esters of o-methylphenyl isopropanol.

This invention provides for biocompatible, biodegradable eye drop pharmaceutical formulations useful for the treatment of ocular indications. In particular, tocopherols and their esters of low water solubility, notably α-tocopheryl acetate, are exceptional vehicles for biocompatible, nonirritating topical eye drop formulations that provide sustained release of active agents.
