Patent number: 8569402Abstract: A biodegradable injection moldable polymer having the composition a) from 50 to 85% by weight of a starch and or a modified high amylose starch b) from 4 to 13% by weight of a water soluble polymer selected from polyvinylacetate, polyvinyl alcohol and copolymers of ethylene and vinylalcohol which have a melting point compatible with the molten state of the starch components c) from 10 to 35% by weight of a polyol plasticizer d) from 0.5 to 10% of a polyethylene oxide or polyethylene glycol e) from 0 to 1.5% by weight of a C12-22 fatty acid or salt and f) from 0.25% to 3% of a food grade emulsifier. The polymers are suitable for biodegradable, flushable tampon applicators and other medical or industrial products where flushability and bio degradability are desirable.Type: GrantFiled: October 5, 2005Date of Patent: October 29, 2013Assignee: Plantic Technologies Ltd.Inventors: Rulande Henderson, Ian John Partridge, Elizabeth Emily Rose, Nicholas Roy Oakley
