Solubility Profile
Water: Slightly soluble (approximately 0.05% or considered practically insoluble in pure water). Solubility varies by pH and is higher in neutral to weakly alkaline solutions (pH 5–8) than in acidic solutions. [1, 2, 3]
Ethanol: Freely soluble in 10% ethanol-water solutions (~59 mg/mL in pure or standard ethanol). [1, 2]
Surfactant Solutions: Soluble in aqueous solutions containing cosmetic surfactants, making it ideal for shampoos and body washes. [1]
Alternative Solvents: Exhibits high solubility in organic and glycol solvents such as methanol (278.4 mg/mL), propylene glycol (248.8 mg/mL), and DMSO (38 mg/mL). [1, 2]
