Influence of alkyl chain length on the action of acetylated
Acetylated monoglyceride (AMG) is one of the most innoxious and effective external plasticizers for poly (vinyl chloride) (PVC) food packaging film because it is approved as a food additive and its carbonyl group of a carboxylic ester and aliphatic side chain of an ester allow unique interactions with PVC.
Influence of alkyl chain length on the action of acetylated
As alternatives to phthalate-derived plasticizers, acetylated monoglycerides (AMGs) containing both hydrophilic and hydrophobic groups have been applied to PVC film, as these are approved as food additives (Lee et al., 2017 ).
Polyvinylchloride plasticized with acetylated monoglycerides
To replace phthalate plasticizer for PVC, acetylated monoglyceride (AMG) plasticizers were prepared from plant oil and their plasticization effects were also investigated....
Pharmaceutical Applications of Plasticized Polymers - IntechOpen
dissolves at a pH of 5.5. The plasticizers as triacetin, acetylated monoglyceride, diethyl phthalate are recommended, and to obtain the best enteric coating results from aqueous processing, ammoniated solutions of CAT in water are the best choice. Hydroxypropyl methylcellulose phthalate (HPMCP) characteristics, particularly at the pH
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
- Can acetylated monoglycerides be used for plasticization of poly(vinyl chloride)?
- Acetylated monoglycerides (AMGs), food additives, are used for external plasticizers. Effective alkyl chain length of AMG for poly (vinyl chloride) plasticization was investigated. The optimum alkyl chain length for an AMG was C14:0. The performance of C14:0-AMG was slightly better than dioctyl terephthalate.
- What is acetylated monoglyceride (AMG)?
- Acetylated monoglyceride (AMG) is one of the most innoxious and effective external plasticizers for poly (vinyl chloride) (PVC) food packaging film because it is approved as a food additive and its carbonyl group of a carboxylic ester and aliphatic side chain of an ester allow unique interactions with PVC.
- Why do AMG plasticizers have unique rheology in PVC films?
- AMG plasticizers have unique rheology in PVC films because they can be synthesized with various fatty acids hydrolyzed from vegetable oils. The physical and chemical properties of AMG plasticized PVC are significantly affected by alkyl chains acting as spacers.
- Can acetylated monoglycerides be used as food additives?
- As alternatives to phthalate-derived plasticizers, acetylated monoglycerides (AMGs) containing both hydrophilic and hydrophobic groups have been applied to PVC film, as these are approved as food additives ( Lee et al., 2017 ).
- Why do AMG plasticizers have a shorter alkyl chain length?
- AMG plasticizers with a shorter alkyl chain length exhibited higher migration stability and compatibility with PVC in this system because plasticizers composed of long straight chains cause plasticizer-plasticizer interaction resulting in anti-plasticization.
- How do alkyl chains affect the physical and chemical properties of AMG Plasticized PVC?
- The physical and chemical properties of AMG plasticized PVC are significantly affected by alkyl chains acting as spacers. Shorter alkyl chains can be formulated more easily and exhibit lower migration rates and T g, whereas longer alkyl chains provide higher thermal stability and hardness.
