Abstract:
N‐reacetylated oligochitosan (RA‐oligoCHI) with molecular weight ≤ 12 kDa and a random‐type distribution of acetyl groups can form soluble RA‐CHI/SDS (SDS; sodium dodecyl sulfate) complexes and transparent solutions both in acidic, where RA‐oligoCHI is soluble, and alkaline aqueous media, where RA‐oligoCHI is soluble too, at SDS concentration above its critical micellar concentration. AN antibacterial activity test shows that RA‐CHIs preserve a high bacteriostatic activity toward S. aureus and E. coli in the presence of SDS both in acidic and alkaline aqueous solutions. The discovered compatibility and preservation of antibacterial activity can make promising the application of RA‐CHIs as artificial biocides for the preparation of microbiologically stable pharmaceutical hydrocolloids and cosmetic compositions containing strong anionic surfactants designed for topical applications.
