OkeiF.C. 4200614Cosmetic emulsions were prepared using four different neutralizers; borax, sodium hydroxide, sodium carbonate and alkali extract from coconut husk (Cocos nucifera). The effectiveness of each of these materials as neutralizers/co-emulsifiers and as replacement for conventional neutralizer (borax) in cosmetic emulsions was evaluated by preparing samples of creams and lotions with these materials using a standard formulation. The samples were stored under ambient conditions and both microbial and physicochemical parameters were determined. The results obtained show that the materials are stable as alternative neutralizers/co-emulsifiers to borax in cosmetic emulsion preparations.]]>Beans, H.S.,197224120128Bloodfied, D.,1988pp: 210pp: 210Jay, J.M.,19965th Edn.,Jellinek, J.S.,1995pp: 45pp: 45Kirt-Othmer, O.,19851985Lloyd, I.O.,1962Malhotra G.G. and J.I., Zatz,200291312323Motwani, M.R., L.D.
