  • Patent number: 9844216
    Abstract: The present invention provides a chemical composition comprised of hydrogen peroxide and a nanoemulsion of long-chained alcohols which in combination these constituents act synergistically boost the kill-time rate of hydrogen peroxide. The peroxide based nanoemulsion formulation for application to skin includes a cosmetically approved peroxide containing compound present in a range to give from about 0.1 to about 4 wt./wt. % released hydrogen peroxide, an organic acid present in a concentration from about 0.01 to about 5 wt./wt. % for adjusting a pH of the formulation in a range from about pH 1 to about pH 4, a long-chained (C9 to C22) aryl and/or alky! alcohol, present in a concentration from about 0.1 to about 20 wt./wt. %, and an emollient present in a concentration from about 0.1 to about 40 wt./wt. %, and an emulsifier present in a concentration from about 0.1 to about 20 wt./wt. % to render the formulation a nanoemulsion.

  • Publication number: 20050233914
    Abstract: This invention provides heavy-duty cleansers (HDHC), with a high level of biodegradability and little or no ecotoxicity, with a high level of efficiency and a maximum skin tolerance and no systemic toxicity. In the broadest aspect of the invention there is provided a cleansing formulation comprising 5 to 10% of one or more methylesters of vegetable saturated and/or unsaturated fatty acids which may be from several natural sources including sunflower seed oil, soybean oil, rape seed oil, or coconut oil. The formulation includes between about 10% to 30% of one or more surfactants and a preferred combination of surfactants includes at least one ethoxylated fatty alcohol, one alkyl polyoxyethylene glycol, one alkanolamide and one polymeric quaternary ammonium salt.
