Characterisation of cosmetic creams prepared by hot mixing technique and cold mixing technique / Nur Amirah M. Bakri

Mixing process is one of the most important steps in formulating creams or emulsions. Creams were formulated using hot mixing technique and cold mixing technique. Hot mixing technique involves incorporation of heat while cold mixing not. These two mixing techniques were subjected to two formulations...
