Endpoint:
water solubility
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
August 2017
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: accepted calculation method
Qualifier:
no guideline followed
Principles of method if other than guideline:
Water solubility is calculated using the program WATERNT v1.01 (part of US EPA EPI Suite v4.00). The estimation methodology is based upon a "fragment constant" method very similar to the method of the program KOWWIN (see Sect. 4.7)

Executive summary:

Water solubility of diisotridecyl adipate was calculated using the Fragment Contribution method developed at Syracuse Research Corporation for US EPA. With the program WATERNT v1.01 (part of US EPA EPI Suite v4.00), water solubility of Butanedioic acid, 2,3-dihydroxy- [R-(R*,R*)]-, C12-13-branched alkyl esters was estimated to 0.0016787 mg/L (C12 -branched component); 0.00014972 mg/L (C13 -branched component).

Description of key information

The two type of fragments that constitute the substance Butanedioic acid, 2,3-dihydroxy-[R-(R*,R*)]-, C12-13-branched alkyl esters have a solubility of 0.0016787mg/L (C12) and 0,00014972 mg/L(C13).

Key value for chemical safety assessment

Water solubility:
0.002 mg/L
at the temperature of:
25 °C
