Based on the precautionary principle, current legislation limits the use of non-classified high phthalates di-isononyl phthalate (DINP), di-isodecyl phthalate (DIDP) and di-n-octyl phthalate (DNOP) which cannot be used as substances or as constituents of preparations, at concentrations of greater than 0,1 % by mass of the plasticised material, in toys and childcare articles which can be placed

In particular, tributyl citrate (TBC) is an vital thermally stable and non-toxic plasticizer having numerous applications in polymer industries such as solvent for synthesis of polyvinyl chloride (PVC) and its copolymers, which are subsequently applied to food wrapping film (Kolah et al., 2007, Kolah et al., 2008, Lemmouchi et al., 2009, Nandiwale et al., 2014, Xu et al., 2010, Xu et al., 2011

The estd. daily intakes of total phthalates (n = 7) by children and toddlers through indoor dust in childcare facilities were 1.6 times higher than the non-phthalate plasticizers (n = 3), whereas estd. daily intake of total non-phthalates for all age groups at homes were 1.9 times higher than the phthalate plasticizers.

Designing bio-based plasticizers: Effect of alkyl chain length on

A novel multifunctional plasticizer, cyclohexyl triethylene glycol oligo-lactate (CTLE) was designed by a two-step esterification reaction using green non-toxic biomass lactic acid as raw material. Its structure was characterized by 1 H NMR, FT-IR and TOF-MS. Thermogravimetric analysis (TGA), tensile test and leaching test were used to evaluate the plasticizer effect of PVC or PLA blends.
