abstract
Modern skincare products are formulated using plant extracts as active ingredients. Leaf and stem of Talinum triangulare and leaf and bark of Dacryodes edulis extracts were used for the development of cosmetic formulations for in vivo evaluation of their moisturizing effects. Absence of redness, itching, or blemishes on the forearms of volunteers, with the cream without the extracts (control) and with creams containing the extracts (actives), confirmed the safety of these formulations. The pH of the active creams and control (4.9-5.4) were within the pH of the skin. There were no coalescence of dispersed phase, phase separation and change in colours of the active creams and the control from their respective initial colours stored at 7 °C, 30 °C and 40 °C for 90 days. Creams prepared with ethanol extracts of T. triangulare leaf hydrated the skin more than the other plant materials, indicating its potentials as moisturising ingredient to treat dry skin.
