Formulation of Lotion and Cream Containing Water Extract of Commiphora abyssinica Gum Resin

The goal of the project was to formulate oil in water emulsion containing glycerin, petroleum jelly, Castor oil, mineral oil and other additives including water extract of Cammiphora Abyssinia from Kajiado County. Oil and water phases were heated to 90°c then mixed. The mixture was brought to 50°c with constant stirring. During phase ratio optimization, oil phase was progressively reduced from 50%, 40%, 30%, 20% and 16% while emulsifiers, polysorbate 80   (tween 80) and glycerol monostearate (GMS) remaining at 2.5%. 23% oil phase was found to be optimum for lotion and 30% for cream. 40.091g of the raw sample, myrrh gum resin, was extracted with 200ml distilled water. The filtrate was evaporated at 105°c to a thick paste of yield 72% (28.920). The paste was used in formulation though solid particles were in the emulsion because the extract did not re-melt. To avoid these particles, 5g and 2g of raw sample was each extracted with 100ml water and the filtrate used to obtain 76.2% and 72.4% water phase respectively. Here, emulsifiers, GMS and tween 80 was reduced from 2.8% to  1.8%. Finally cream and lotion were successfully formulated.

The main objective of the study was to formulate a simple cream and lotion from oil in water emulsion of Castor oil, mineral oil, petroleum jelly, glycerine and water extract of Commiphora abyssinica gum resin. Specific objectives: i) Optimize oil/water phase ratio for lotions and creams containing glycerin, petroleum jelly, Castor oil, mineral oil as main ingredients; ii) Incorporation of water extract of Commiphora abyssinica gum resin in lotions and creams
