Investigating the endocrine disrupting potential and cytotoxic effects of packaging leachates and plasticisers
Endocrine disrupting chemicals are compounds which can alter the function(s) of the endocrine system by disrupting natural signalling, production and secretion of hormones, contributing to a wide range of adverse health effects. Plastic packaging and films have been identified to leach …

Biodegradable food packaging using agricultural wastes (Banana Pseudostem)
… improve the quality of the film by incorporating plasticisers (glycerol and polyethylene glycol (PEG)) and nanofillers (nanoclay and graphene oxide) into the nanocellulose matrix. The addition of plasticisers did improve the film elasticity. Relative to the glycerol, PEG only slightly influenced …

Generation of sustainable active food packaging materials from agricultural wastes
… active food packing materials using various plasticisers as well as the effects of supplementation of cassava peel starch-based films with plant extract and essential oil on film’s physical, optical, chemical, and functional characteristics. Results: Significant amount of starch was extracted …

Foaming Novatein thermoplastic protein
… Water and triethylene glycol (TEG) are added as plasticisers to produce a powder which can be extruded, and subsequently injection moulded. As Novatein is both bio-derived and biodegradable there is the opportunity for using it as an alternative loose fill packing material. This work aimed to …

Studies of physical properties of novel lithium polymer electrolytes.
… ratio of lithium triflate and ECIPC plasticisers introduced into the polymer aided by volatile solvent. Without any plasticiser, the TPUlLiCF3S03, modified natural rubber and modified natural rubberIPEO blend based polymer electrolyte systems have ionic conductivity in the range 10-6 …

The Biodegradation of Certain Components of Town Waste by Thermophilic Fungi
… produce esterase enzymes when grown upon ester plasticisers, Finally, all thermophilic fungi under test were able to produce humus substances which were similar in composition to substances isolated from composted town waste.

Characterisation and plastic-degrading potential of plastisphere-associated microorganisms
… spp., reported to degrade LDPE and common plasticisers. Despite these findings, the greatest impact on microbial functional diversity was related to seasonal variation and depth of the plastic; plastic type did not significantly impact microbial community functional traits. This thesis …

Studies on the hydro-thermal and viscoelastic properties of leather
… It is also shown that tanning agents act as plasticisers and depress the glass transition temperature to a lower temperature. Thus the tanning process itself may be viewed as a plasticisation of the collagen molecule. In this event, tanning molecules interpose themselves between the collagen …

A methodology for developing high damping materials with application to noise reduction of railway track
… rubbers with various amount<br/>of fillers and plasticisers are investigated. The properties of both rubbers have been<br/>measured over the range of temperatures for frequencies 300-3000 Hz. For this a test<br/>rig had to be modified. For butyl, the best combination of filler and plasticiser …

New extraction protocols for the determination of endocrine disrupting compounds in samples of environmental and agri-food interest
… have endocrine disrupting activity, their use as plasticisers in industrial applications stands out from any other. While it is true that plastics are polymers of high molecular weight which do not normally constitute a risk for humans, these additives are not chemically bonded to them and show a …

Evaluation of the critical parameters and polymeric coat performance in compressed multiparticulate systems
… to study the influence of the level and type of plasticisers incorporated in coating film formulation on the performance of the coating film. In this study, both DSC and DMA were used to investigate the Tg for each film coating formulation in order to evaluate the effect of the additives. In …

Solvent Free Technologies for Polymer based Crystal Engineering and Drug Delivery
… properties HME process needed addition of plasticisers during preparation of solid dispersions whereas S3M was plasticiser free process which gave good insight on how this will affect the product performance during evaluation studies. The solid dispersions in case of HME were had smooth …
