a container is provided for substances that contain an antibacterial compound . the container is comprised of a tube body and a tube shoulder that includes a tube nozzle . the tube body may have a laminate structure . the tube shoulder may be comprised of an alkene based polymer such as a polyethylene or a polypropylene . such alkene based polymers have a high absorptivity for antibacterial compounds such as triclosan . it has been found that the absorptivity for triclosan can be reduced through the use of at least one of polytrimethylene naphthalate , polyethylene naphthalate and acrolonitrile / methacrylate as the surface contacting the composition containing the antibacterial . this surface can be a film on the tube shoulder / nozzle , the full structure of the tube nozzle , an insert in the tube nozzle or a co - injection molded surface on a shoulder / nozzle . the absorption is less than 1 . 0 mg / dm 2 .
