capacity and EA, besides stabilizing emulsions. TM contributes to obtaining stable cosmetic emulsions, similar to emulsions obtained using xanthan gum. All samples presented pseu- doplasticity, with fl ow indexes lower than 1, a desirable characteristic in cosmetic formula- tions, as it improves their applicability. These results appear as important responses to the potential use of TM as an emulsifying agent for cosmetic emulsions, since the scenario has a good market forecast for plant-derived cosmetics. With high acceptance rates due to their nontoxicity and nonirritating characteristics, natural mucilages are gaining attention from the cosmetics sector, being an alternative to conventional biopolymers.
