Bodies get taller, muscles get stronger \u2014 and often, body odor becomes more pungent. Now, scientists have identified some of the compounds that give teenagers their natural aroma.<\/p>\n\n\n\n<p>Unlike that of infants and toddlers, <a href=\"https:\/\/www.nature.com\/articles\/s42004-024-01131-4\" target=\"_blank\" rel=\"noopener\">teenage body odor has two smelly steroids<\/a> and higher levels of carboxylic acids, researchers report March 21 in <em>Communications Chemistry<\/em>. Those chemicals form when bacteria break down armpit sweat and sebum, the oily secretions that keep our skin moist, and may contribute to the noticeable changes in BO throughout puberty.<\/p>\n\n\n<aside class=\"sn-conversion rich-text rich-text--with-sidebar\">\n<style><![CDATA[\n.email-conversion {\n  border: 1px solid #ffcccb;\n  color: white;\n  margin-top: 50px;\n

through development,\u201d says chemist Helene Loos of Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg in Germany. \u201cThere is a really great diversity of different odor compounds that are present in body odors.\u201d<\/p>\n\n\n\n<p>Loos and colleagues collected body odor samples from 18 teens age 14 to 18 and 18 young children age 0 to 3 who had slept with cotton pads under their arms for a night. Separating the body odor into individual components revealed that young children and teens have over 40 compounds in common.<\/p>\n\n\n\n<p>While some classes of chemicals showed no difference between age groups, the scents of carboxylic acids were more prevalent in teens. These compounds were a mix of pleasant scents, described by a panel trained to evaluate olfactory cues as fruity, soapy or grassy, and less-appealing ones that smelled cheesy, musty or goatlike.<\/p>\n\n\n\n<p>Researchers also identified two steroids present only in the teens\u2019 body odor. One, called 5\u03b1-androst-16-en-3-one, smells of sweat, urine and musk. The other, called 5\u03b1-androst-16-en-3\u03b1-ol, smells of musk and sandalwood.<\/p>\n\n\n\n<p>A few components of scented products also turned up, despite participants avoiding deodorant and using unscented body wash and detergent for two days prior to the study.<\/p>\n\n\n\n<p>Notably, some compounds known to contribute to strong body odor weren\u2019t detected, says biochemist Andreas Natsch of Givaudan, a fragrance and flavor manufacturer headquartered in Vernier, Switzerland. Those chemicals might require different detection techniques, or they may show up more after exercising or <a href=\"https:\/\/www.sciencenews.org\/article\/joy-of-sweat-book-perspiration-science-history\">working up a sweat<\/a> (<em>SN: 7\/13\/21<\/em>).<\/p>\n\n\n\n<p>In future work, Loos hopes to look for those compounds and to study <a href=\"https:\/\/www.sciencenews.org\/article\/youngsters-can-sniff-out-old-peoples-scent\">how BO changes at other stages of development<\/a> (<em>SN: 5\/30\/12<\/em>).<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>","protected":false},"excerpt":{"rendered":"<p>Puberty changes just about everything.
