  • Patent number: 6846846
    Abstract: Antimicrobial compositions having synergistic combinations of octoxyglycerin and at least one other antimicrobial agent in formulations which are more effective than prior art compositions without causing increased irritation to the skin of the average user. In certain embodiments, skin irritation may be minimized by low concentrations of antimicrobials and/or the presence of soothing compounds such as zinc. Preferred embodiments include combinations of octoxyglycerin, a quaternary compound, and at least one other antimicrobial agent. Without being bound to any particular theory, it is hypothesized that the unexpected antimicrobial effectiveness of combinations of octoxyglycerin may result from an enhancement of the permeability of microbes to antimicrobials caused by octoxyglycerin.

  • Publication number: 20040208908
    Abstract: Medical articles impregnated with antimicrobial compositions containing synergistic combinations of octoxyglycerin and other anti-infective compounds are disclosed. Such medical articles may include urinary catheters, central venous catheters, tracheal catheters, arterial grafts, wound dressings, sutures, or any other medical articles derived from polymeric substrates such as biomedical polyurethane, biomedical polyvinylchloride (PVC), biomedical silicon, biodegradable polymers, polytetrafluoroethylene (PTFE), etc. or from natural products including natural rubber, silk or cotton fiber.

  • Publication number: 20040102429
    Abstract: The addition of low concentrations of combinations of water-soluble organic salts of zinc to gels, creams, lotions or ointments can increase the ability of these products to reduce or prevent exogenous irritants from causing irritation of the underlying substrate. The addition of low concentrations of combinations of water-soluble organic zinc salts to these gels, creams, lotions or ointments also can reduce the irritation of skin or mucous membranes caused by the addition of potentially-irritating substances such as spermicides, microbicides, fungicides or other therapeutic agents to the gel, cream, lotion or ointment. The advantages of this anti-irritant approach over others, which generally employ high concentrations of single zinc salts, are the reduced potential for zinc toxicity, the reduced potential for toxicity related to zinc itself, and the preservation of the desirable biological properties of potentially-irritating therapeutic substances added to the gel, cream, lotion or ointment.
