Notes

“A disposable (also called disposable product) is a product designed for a single use after which it is recycled or is disposed as solid waste. The term often implies cheapness and short-term convenience rather than medium to long-term durability. The term is also sometimes used for products that may last several months (ex. disposable air filters) to distinguish from similar products that last indefinitely (ex. washable air filters).” (Disposables, Wikipedia, 8/23/2013

Patent Abstracts

1. Water Dispersible Products

U.S. Patent 8,569,402 (October 29, 2013), “Mouldable Biodegradable Polymer,” Rulande Henderson, Ian John Partridge, Elizabeth Emily Rose, and Nicholas Roy Oakley (Plantic Technologies Ltd., Altona, Victoria, Australia).

Disposable materials such as  tampon applicators should be water flushable, water dispersible and biodegradable.  Starches are desirable but difficult to process by common processes such as injection molding.  Henderson et al developed a biodegradable injection moldable material consisting of a) 50 to 85 wt% starch,  b) 4 to 13 wt% water soluble polyvinylacetate, polyvinyl alcohol or ethylene /vinylalcohol copolymers, c) 10 to 35 wt% polyol plasticizer, d) 0.5 to 10 wt% polyethylene oxide or polyethylene glycol,  e) 0 to 1.5 wt%  C12-22 fatty acid or salt, and f) 0.25 to 3 wt% of a food grade emulsifier.
