| Enhancer | PEG ointment base vehicle was used | |
| Properties of enhancer | Not mentioned | |
| Concentration | PEG ointment base(26% PEG 400 and 74% PEG 3350 ) was liquified on heating.The melanotropins were dissolved in this vehicle and 0.5 ml aliquots, the amount to be applied daily to each animal, were divided before the vehicle resolidified. | |
