Abstract: A germicidal absorptive material for use in surgical packings, wound bandages, sanitary tampons and bed sore prevention and/or treatment uses is provided by a foam-like matrix of hydrophilic polyurethane polymer to which application-specific loads of a germicidal disinfectant dye have been made. Polyurethane polymer of various densities and thicknesses exhibits an exceptional ability to absorb different levels of a number of disinfectant dyes, both basic and acidic, such as gentian violet and methylene blue, respectively. The relationship between dye-load and application-specific uses permits a totally-bound gentian violet pad to be used as a conventional bandage or pad on a surface wound with the capability of preventing the incursion of external pathogens from entering the wound through the pad, where the pathogens are killed by the bound-dye. The wound exudate is absorbed safely by the pad, where wound-originating pathogens are also killed. When the loaded dye's concentration is saturated by exceeding the bound-dye limit, the limited free-dye is available to be delivered to the wound, particularly deep wounds, to rapidly kill pathogens in the wound. The free dye delivery pad can then be replaced by the bound-dye pad to absorb the wound exudate.

Abstract translation: 用于手术包装，伤口绷带，卫生棉塞和床防止和/或治疗用途的杀菌吸收材料由亲水性聚氨酯聚合物的泡沫状基质提供，其中已经制备了杀菌消毒剂染料的施用特异性负载 。 各种密度和厚度的聚氨酯聚合物具有分别吸收碱性和酸性的许多消毒剂染料的不同水平的特殊能力，例如龙胆紫和亚甲基蓝。 染料负载和应用专用用途之间的关系允许使用完全结合的龙胆紫色垫作为在具有防止外部病原体侵入外部病原体通过垫进入伤口的表面上的常规绷带或垫， 其中病原体被结合染料杀死。 伤口渗出物被垫子安全吸收，伤口源性病原体也被杀死。 当加载的染料浓度超过界限染料极限时饱和，有限的自由染料可以传递到伤口，特别是深层伤口，以迅速杀死伤口中的病原体。 然后可以通过结合染色垫来替代游离的染料输送垫以吸收伤口渗出物。

Abstract: The color and color stability of tall oil fractions are improved and the odor and sulfur content are reduced by treating the heated black liquor soap skimmings prior to acidulation with 1.0 to 1.5 wt. % hydrogen peroxide for at least one minute.
