Nowadays, more and more people are concerned about the safety and carcinogenicity of some components used as antiperspirants inside deodorant formulas, for instance aluminum salts . The consumers are searching for a smooth alternative to this kind of ingredients that would not impede perspiration.
SEQENS Mineral Specialties carried out a sensory analysis to compare the anti-odor efficacy of three different formulas of roll-on deodorants: one with sodium bicarbonate, one with anti-odor active and one with placebo. 24 subjects have participated in the study and a trained jury of five people has assessed the perspiration smell intensity, and the hedonic value of the smell 8 and 12 hours after the standardized application. Furthermore, the formulas were hidden (masked review). This study allows to prove scientifically that sodium bicarbonate has efficient anti-odor properties and can be an alternative to antiperspirants for the formulation of deodorants.
