Activated ALOXICOLL® LR is an enhanced efficacy antiperspirant active, providing improved sweat reduction over standard Aluminum Chlorohydrate powder, ALOXICOLL® PF40. The increase in efficacy is attributed to an activation step, which causes a change in the polymer distribution. This can be measured by HPLC. A shift of polymers from bands 1 and 2 to band 3 indicates an enhanced sweat reduction. Activated ALOXICOLL® LR powder is a special, “low residue” active, which considerably reduces the level of visible deposits on the skin when used in formulations.
