Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Principles of method if other than guideline:

Experimental Design:
Solubility of the test material in propylene glycol at 250 mg/mL, at ambient conditions, was assessed by visual inspection.

GLP compliance:

yes

Specific details on test material used for the study:

Test Material Name: Octenylsuccinic acid
Chemical Name: 2-(Octen-1-yl) butanedioic acid
Synonyms: DF-20 Acid, OSAC
Lot/Reference/Batch Number: 8515025
Purity/Characterization (Method of Analysis and Reference): The purity of the test material was determined to be 99.2% area by high performance liquid chromatography with identification by liquid chromatography mass spectrometry and nuclear magnetic resonance (Megregian, 2016).
Test Material Stability Under Storage Conditions: Octenylsuccinic acid, lot 8515025, was determined to be stable for 2 weeks at 54°C which is equivalent to 24 months under ambient storage conditions as tested under U.S. EPA OPPTS Guideline 830.6313. (Megregian and Crispin, 2016).

Medium:

other: propylene glycol

Solubility:

250 other: mg/ml

Temp.:

20 °C

Remarks on result:

other: Solubility was determined at ambient temperature.

Test substance stable:

yes

Details on results:

A solubility assessment was performed by dissolving 2.5 g of octenylsuccinic acid test material (Lot 8515025) in 10 mL of propylene glycol. Solubility was confirmed by visual inspection at a concentration of 250 mg/mL propylene glycol.

Conclusions:

Solubility of octenylsuccinic acid (Lot 8515025) has been demonstrated at a concentration up to 250 mg/mL.

Executive summary:

This study was conducted to determine the solubility of octenylsuccinic acid in propylene glycol at ambient temperature, exposed to normal lighting conditions. Octenylsuccinic acid, when mixed in propylene glycol, was demonstrated to be soluble in propylene glycol at a concentration of 250 mg/mL.
