Effective axillary malodor reduction by polyquaternium ‐16‐containing deodorants

ConclusionWe identified polyquaternium‐16 (PQ‐16, copolymers of 1‐vinyl‐2‐pyrrolidone and 1‐vinyl‐3‐methylimidazolium chloride) as a highly effective deodorant active. Results showed that a newly developed PQ‐16‐containing deodorant roll‐on formulation 1) significantly reduced axillary malodor 24 h and 48 h after treatment, 2) significantly decreased the amount of axillary bacteria, 3) compared to a commercially available deodorant claiming a 24 h odor protection significantly lowered axillary malodor 24 h and 48 h after application, and 4) was well tolerated by the study population. PQ‐16 represents an innovative and skin‐friendly deodorant active.This article is protected by copyright. All rights reserved.
