Cosmetic 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.
