Topical Compositions In The Form Of A Gel Containing A Particular Solubilised Retinoid

Patent No. EP2854803 (titled "Topical Compositions In The Form Of A Gel Containing A Particular Solubilised Retinoid") was filed by Galderma Research on May 30, 2013. The application was issued on Aug 24, 2022.

Patent Summary

Stable, well-tolerated gel compositions containing the retinoid compound 3"-tert-butyl-4'-(2-hydroxy-ethoxy)-4"-pyrrolidin-1-yl-[1,1';3',1"]-terphenyl-4-carboxylic acid for topical application. The compositions are aqueous hydroglycolic gels containing the retinoid dissolved in hydrophilic solvents like phenoxyethanol and ethanol, as well as co-solvents like propylene glycol and dipropylene glycol. The gels are stable and tolerated because they avoid emulsifiers and use hydrophilic solvents and co-solvents to solubilize the retinoid.
