  • Deodorants neutralize odor-causing bacteria with ethanol or triclosan.
  • Often contain fragrances to mask body odor without stopping sweat.
  • Preferred by those seeking natural sweat regulation without blockage.

Chemical Differences

  • Antiperspirants: Aluminum-based, pH 3-4, targets sweat glands directly.
  • Deodorants: Alcohol-based, pH 5-6, focuses on bacterial growth prevention.
  • Combination products exist but may irritate sensitive skin.
