In this study, three cosmetic creams containing/with different lemon extracts were formulated and studied from a rheological point of view. Rheological tests such as: the flow test, amplitude sweep and frequency sweep were determined by specific measurements and showed that the products formulated based on lemon extracts are stable at different temperatures and can easily be applied to the skin. Additional microbiological tests and clinical studies are required for cosmetic creams to be marketed.
Cobzaru et al. (Wed,) studied this question.
