Abstract

Of all the natural functions of the skin, perspiration and its odorous consequences is one of the most lucrative challenges of the cosmetic industry, especially due to its social impact . Body odor and perspiration is deemed offensive in most cultures and cosmetic products to control this phenomenon are in high demand. The reduction of sweat and its resulting odor is normally addressed by antiperspirant formulations containing aluminium salts and standard antimicrobial actives. However concerns over environmental safety, cancer, health and wellbeing are driving innovation in new directions. A wider understanding of the potential positive and negative effects of antiperspirants and deodorants on the skins natural microbiome is becoming more appreciated, alongside a marketing desire for more elaborate claims. This has led to new formulations and different approaches within the confines of legislative requirements for study designs. Here we discuss sweat odor and perspiration, and examine both standard and new developed approaches in clinical testing for claims substantiation within the context of product efficacy, their effect on the skin‘s microbiome and legislative product claims requirements.
