However, it has to be noted that DINP is highly bioaccumulative. Johnson et al. Weak toxic effects were found in one test at a concentration far above the solubility limit. The effect concentrations measured are, however, far above the water solubility of the substance. From the above results, DINP seems to have no acute or chronic toxicity to algae. Hydrolysis and photodegradation are not significant degradation routes of DINP in the aquatic environment. No experimental data on photodegradation of DINP are available. The NOEC values given are all far above the water solubility of the substance. From Wikipedia, the free encyclopedia.
Diisononyl phthalate (DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of Diisononyl phthalate Formula Vsvg.

< g/mL at 20 °C. Repeated dosing does not result in accumulation of DINP and/or its metabolites in . (14)C-diisononyl phthalate (DINP CAS% pure) were . If DiNP is released to the environment it will bind to particles in soil and water. Diisononyl phthalate. 1 Product Result. | Match Criteria: CAS Number, Related Cas Number.
Diisononyl phthalate ester content ≥99 % (mixture of C9 isomers),.
However, mass balances show that most of the amount in the inlet water is found in sludge, which indicates that the degradation of DINP is limited and that DINP is adsorbed to and follows the sludge.
Views Read Edit View history. No experimental data on the hydrolysis of DINP are available. However, the toxicity observed is expected to be ascribed mainly to an indirect effect such as floating entrapment or microdroplets which may adhere to the surface of the animals. No acute toxicity has been measured at concentrations at or below the solubility limit.
The reason for the variability should most probably be sought in experimental difficulties arising from the low water solubility of DINP.

|An overview of the results is given in Table 8.
The NOEC values given are all far above the water solubility of the substance. Estimated photodegradation half-lives in the atmosphere are in the range from 0. However, taking the relatively high biotransformation of phthalatic esters into account, steady state conditions will probably never be reached for which reason maximum toxicity of DINP will never be seen. A total BCF of was reported by Solbakken et al.
No acute toxicity has been measured at concentrations at or below the solubility limit.

|In a sediment-water system, very low rates of primary biodegradation were found under both aerobic and anaerobic conditions.
Autoignition temperature. Studies find that exposure to environmentally relevant concentrations of DINP in zebrafish disrupt the endocannabinoid system ECS and affect reproduction in a gender specific manner,  and have other adverse effects on aquatic organismsas DINP upregulates orexigenic signals and causes hepatosteatosis together with deregulation of the peripheral ECS and lipid metabolism. Hydrolysis and photodegradation are not significant degradation routes of DINP in the aquatic environment.
As no chronic toxicity tests with fish are available, it cannot be excluded that DINP may cause long-term adverse effects at or below the water solubility of the substance in aquatic organisms caused by direct or indirect effects.
The short-term toxicity data on DINP to freshwater and marine invertebrates are presented in Table 8.
