ACKNOWLEDGEMENT First of all, I acknowledge the grace, favors and blessings of the most high, Almighty Allah upon my life. All that has come of this training, including this report, is by His grace. I would like to show my gratitude to my de facto advisor, Engr. U. Musa. Not only has he motivated me to study on African natural plants but also he really provided me opportunity to work on Shea butter. Since I was a long-time fan of Shea butter products as a consumer, I very much enjoyed working on my research work. With his help and patient guidance, I gained the needed experience and skills to conduct this research, May Allah bless you with all your heart desires and make the hereafter a better one for you. To my parent, Alhaji Albdulrahman,Hajia Fatima and Hajia Halima S. whose support towards.. my education cannot be estimated. Their parental care and moral training given to me is highly appreciated. I am also very indebted to all Staffs (Academics and Non Academics) of the Chemical Engineering Department, Federal University of Technology Minna for the knowledge impacted and to all my coursemate it was a wonderful experience to be part of this great Class, as for those whom I had to share ideas with in the course of this research I say thank you for sparing' your precious moment. My gratitude also goes to my friends Led. Ibrahim Nura, Nneji N. Lynda, Sogbesan A. Adetola, Cyrus Olanrewaju. Oluwarotinii, Dr. A. Jimoh, Dr. F Abdulrahman, Usamatu Salihu, Engr.O.Adedipe, Sheik Uthmaan Suleiman and so many others. I appreciate you all for your total support, I say Jazaakallaahu khairan. v
ABSTRACT Today's average beauty product consumer is most interested in products that can prevent or even reverse the effects of aging rather than those that merely camouflage sagging and wrinkles. Natural products are perceived as being gentler to the skin, especially skin that is highly reactive to synthetic perfumes, oils, and preservatives traditionally u~ed in cosmetic products. This research provides an explicit account on the production and characterization of Shea butter lotion fortified with Aloe Vera gel. The Shea butter oil was sourced locally based on its availability in our environment. Characterization of the Shea oil was done in order to determine its physical and chemical properties such as Acid value of 3.36, saponification value of 162.61, ph of 4.58, free fatty acid of 1.68, moisture content of 0.12, peroxide value of 9.40 and specific gravity of 0.89. The characterized Shea oil was further used to produce a lotion with the addition of stearic acid, Borax, glycerine, methyl paraben, cetyl alcohol, EDTA, distilled water, croda wax, paraffin oil then finally fortified with Aloe Vera gel. The produced lotion was then characterized to determine its thermal stability, non volatile matter, specific gravity, viscosity, water content, oil content, dermatology test, microbial count and free fatty acid. and the results obtained were compared favourably with the NIS ISO 22179 2007 SON standard for cream and lotions. vi
