Non-endocrine disruptor effect for cardanol based plasticizer
Our results revealed that the fatty cardanol plasticizer causes a global decrease in toxicity compared to DINP and no harm for environment and human health were detected without endocrine perturbation effect. These positive results of toxicology allow to consider these cardanol plasticizers in industrial applications as alternative to DINP.

Non-endocrine disruptor effect for cardanol based plasticizer
The main effect of plasticizer is to reduce hardness, softening temperature, elastic modulus and embrittlement temperature, and improve exibility and elongation. ... ... The DMA was performed...
Non-endocrine disruptor effect for cardanol based plasticizer - Europe PMC
Moreover, the eco-toxicity using daphnies, algae, and plants as model organisms and endocrinal disruptor tests (YES/YAS) were realized. Our results revealed that the fatty cardanol plasticizer causes a global decrease in toxicity compared to DINP and no harm for environment and human health were detected without endocrine perturbation effect.
Solvent-free synthesis, plasticization and compatibilization
CA-g-LIR shows obvious plasticizing effect, as is certified by its far high elongation at break (increase of 800%), decreased viscosity (reduction of 62%) and glass transition temperature (Tg, decline of 5.0 °C) compared with LIR. Moreover, CA- g-LIR shows good interfacial performance.
- Are cardanol plasticizers toxic?
- These plasticizers were also compared to DINP, one of the most widespread phthalate plasticizers. Face to the toxicity of phthalates, some teams including Zhou et Zhang evaluated the acute toxicity of cardanol plasticizers in rats and demonstrated the non-toxic character of them with toxic doses over than 3 000 mg/Kg (Zhou et Zhang, 2019).
- Is epoxidized cardanol better than DINP for Plasticized PVC?
- Hence, plasticized PVC with epoxidized cardanol CExEp, exhibits a better thermal stability than with DINP, with respective 5% weight loss at 255, 277 and 283 °C for CE2Ep, CE14Ep and CE181Ep, which demonstrates the importance of epoxy rings for thermal stability of soft PVC.

- Is cardanol a good substitute for phthalates?
- In the last ten years, many studies have been focused on the synthesis of cardanol-based PVC plasticizers. Indeed, due to its aromatic groups bringing thermal stability and its C15 alkyl chain that could confer a plasticizing effect, cardanol can be considered as a promising substituent to phthalates.
- Is cardanol a good thermal stabilizer?
- The differences observed in the first step of degradation could be explained by the fact that cardanol is well-known as good thermal stabilizer ( Menon and Pillai, 1998; Greco and Brunetti, 2010 ).
- What are the constituents of cardanol?
- Cardanol is constituted of a mixture of at least four constituents differing in the unsaturated side chain, namely saturated (5–8%), monoene (48–49%), diene (l6–17%) and triene (29–30%) as illustrated in Fig. 1. Its phenolic group can be functionalized by etherification, esterification…
- What is cardanol extracted from?
- Cardanol, obtained by vacuum distillation of cashew nut shell liquid (CNSL), is a promising non-edible and non-toxic renewable resource. CNSL is directly extracted from the shell of the cashew nut, fruit from cashew tree, Anacardium occidentale.
