sensidin® DO combines the well-known deodorant and skin care properties of ethylhexylgycerin with the antimicrobial properties of octenidine HCI. The synergistic combination of these active ingredients provides good efficacy in deodorants at very low use concentrations. In order to achieve practicable use concentrations for deodorants this combination has been diluted with the widely-used solvent and humectant, propylene glycol. sensidin® DO reliably inhibits the growth and multiplication of odour-causing bacteria on the skin. sensidin® DO is a clear, colourless to light yellow liquid concentrate, with a slight characteristic odour.
