Ranking Plasticizers for Polymers with Atomistic Simulations: PVT, Mechanical Properties, and the Role of Hydrogen Bonding in Thermoplastic Starch: Virgin biopolymers are often brittle and therefore need the addition of plasticizers to obtain the required mechanical properties for practical applications, for example, in bags and disposable kitchen items. In this article, based on a combined experimental and modeling approach, it is shown that it is possible to rank molecules with respect to their plasticization efficiency (depression in glass transition temperature with PVT data and reduced stiffness and strength) by using molecular dynamics simulations. Starch was used as the polymeric matrix material due to its promising potential as a sustainable, eco-friendly, biobased replacement for fossil-based plastics. Three polyols (glycerol, sorbitol, and xylitol), two ethanolamines (tri- and diethanolamine), and glucose were investigated. The results indicate that molecular simulations can be used to find the optimal plasticizer among a set of candidates or to design/identify better plasticizers in a complex polymer system. Glycerol was the most efficient of the six plasticizers, explained by it forming the least amount of hydrogen bonds, having the shortest hydrogen bond lifetimes and low molecular rigidity. Hence, not only was it possible to rank plasticizers, the ranking results could also be explained by the simulations.

Glycerol | Meaning of Glycerol by Lexico: What does glycerol mean? glycerol is defined by the lexicographers at Oxford Dictionaries as A colourless, sweet, viscous liquid formed as a by-product in soap manufacture…

My botty best at summarizing from Wikipedia: glycerol is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic . due to having antimicrobial and antiviral properties it is widely used in wound glycerol is miscible with water and is hygroscopic in nature . it is widely used as a sweetener in the food industry . substituted derivatives labeled with “s 350,000 tons of glycerol were produced per year in the united states alone from 2000 to 2004 . 5.75% of petroleum fuels to be replaced with biofuel sources by 2010 . high purity glycerol (> 99.5%) obtained by multi-step distillation . process involves chlorination of propylene to give allyl chloride . this epichlorohydrin is then glycerol is used as filler in commercially prepared low-fat foods . it is also used as a thickening agent in liqueurs . efforts are being made to convert it to synthetic precursors glycerol and water are used to preserve certain types of plant leaves . as a sugar substitute, it has approximately 27 kilocalories per teaspoon (sugar has 20) it is 60% as sweet as glycerol is categorized by the U.S. Academy of Nutrition and Dietetics as a carbohydrate . it has a caloric density similar to table sugar, but a lower g glycerol is approved for all types of wound care except third degree burns . it is used to package donor skin used in skin grafts and as humectant . glycerol is used in solid dosage forms like tablets as a tablet holding agent . it is also used in blood banking to preserve red blood cells prior to freezing . essential oils are added for fragrance . soap is used by people with sensitive, easily irritated skin . it draws moisture up through skin layers and slows excessive drying and evaporation. glycerol content acts to add viscosity to bio-ink without adding large protein molecules . it is also used as an “alcohol-free” alternative to ethanol as a solvent in herbal extractions fluid extract manufacturers often extract herbs in hot water before adding glycerol . when used as a primary “true” alcohol-free botanical extraction solvent in non-tincture based methodologies . glycerol is bacteriostatic in its action, and ethanol is bactericidal in it action . the minimum freezing point temperature is about 36 °F (38 °C) glycerol was historically used as an anti-freeze for automotive applications . it was replaced by ethylene glycol, which has a lower freezing point . synthetic gycerol processes were national defense priorities in glyceryl trinitrate (GTN) is commonly used to relieve angina pectoris . external vibrations can cause the needle to move excessively, giving inaccurate readings . excessive swinging of the needle solution is vaporized and pushed into the room with a ventilator . it creates longer-lasting bubbles by reducing water evaporation . Glycerol metabolization is reduced in both cirrhosis and fatty liver disease . blood levels are highly elevated during Diabetes . direct treatment of testes has been found to cause significant long term reduction in further testing on this subject was abandoned due to the unexpected results . glycerol has very low toxicity when ingested; its LD50 oral dose for rats is 12600 mg/kg and 8700 mg/ hundreds of fatal poisonings in Panama resulting from falsified import customs declaration . cheaper diethylene glycol relabeled as the more expensive glycerol .
