This application is a continuation-in-part of U.S. esophagus, anus and Vagina. Ser. No. 10/662,560 filed 18 Jul. 2003. This application also 0009. It has been suspected that creams containing peanut claims benefit to U.S. Ser. No. 60/507,117 filed 1 Oct. 2003. oil may be a cause of nut allergy (Lever, British Medical Journal 313:299-300, 1996). A recent study revealed that FIELD OF THE INVENTION infants sensitized to peanuts might have been exposed to peanut oil (Lack et al., New England Journal of Medicine 0002 The invention relates generally to medicated skin 348:977-985, 2003). Yet, peanut oil can be found in certain treatment compositions and more particularly to a vehicle, compositions. Such as in injectables, where the oil serves as Such as a cream, lotion, balm, ointment, gel and the like a reservoir of a drug. Thus, there remains no appreciation of containing a medicament for the treatment of a skin condi employing peanut oil that is non-allergenic, and there is no tion. appreciation of the skin hydrating properties of non-aller BACKGROUND OF THE INVENTION genic, refined peanut oil in a topical formulation. 0010. The refined peanut oil of interest is commercially 0003 Medicinal topical preparations can serve as drug available (Welch, Holme & Clark, Newark, N.J.). A refined delivery means. The vehicles thereof carry the pharmaco peanut oil of interest is one that is suitable for pharmaceu logically active agents to the skin, but also can serve as a tical use and is substantially free of proteins, and particularly depot for delivery of the drugs intradermally or transder those proteins known to be allergenic in humans, such as the mally. area h glycoproteins. Thus, a peanut oil of interest is treated 0004) Other topical preparations do not serve to deliver a to deactivate, to remove the biological activity, and at the therapeutic agent but may serve to treat various skin con least, the immunogenicity of Such proteins and thus essen ditions, by, for example, softening of the skin, tightening of tially is hypoallergenic and preferably non-allergenic. the skin or moisturizing the skin. 0011 For example, a refined peanut oil of interest is 0005 There remains a need in the art for a therapeutic treated with alkali (or other refining solution) and/or heat. product and approach that can contain one or more active Many peanut oil impurities, including the proteinaceous agents or medicines using a vehicle with beneficial proper allergens can be hydrated, and then separated. A water ties. Such a vehicle, for example, a cream, would be one that washing can be used to remove such impurities, the bulk of has hydrating effects on human skin. Such a therapeutic which often are removed in the form of soaps, with the carrier would ameliorate any drying, irritating or debilitating proteins attached or associated with the Soaps.

DETAILED DESCRIPTION OF THE 0015. A refined peanut oil of interest can be treated by INVENTION other methods, the goal being to inactivate or remove the 0007. The instant invention relates to a novel and useful peanut oil allergens. vehicle for topical non-pharmaceutical and pharmaceutical 0016 Inactivation of the peanut oil allergens can be applications. The topical vehicle is a mixture, Suspension or monitored using any of a variety of methods, for example, emulsion of a variety of hydrophobic and hydrophilic the tests available from Neogen (Lansing, Mich.). Antibody reagents. The instant formulation can be in the form of a to the various areah glycoproteins is commercially available cream, paste, unguent, lotion, ointment, gel, serum, balm, or can be made practicing known immunology methods. salve, mousse, and other known compositions. Both polyclonal or monoclonal antibodies can be made and 0008. The instant topical vehicle is one that carries supe used. Current commonly used antibodies are polyclonal, rior and unexpected properties, such as excellent skin being raised to a collection of peanut protein, and thus to a hydrating properties, and Such properties are obtained by the variety of allergens. The use of such antibodies for the inclusion of a non-allergenic, refined peanut oil in the detection of peanut allergens can rely on any of the known vehicle. To obtain the enhanced skin hydrating properties of assay formats, such as an ELISA. Commercially available a formulation of interest, the topical vehicle preferably is for tests can detect as little as 2.5 parts per million (ppm) of US 2007/O 140999 A1 Jun. 21, 2007
