摘要:
Certain non-silicone vulcanized rubber articles made from at least a majority by weight of ethylene-propylene-diene modified (terpolymer) rubber (such as, without limitation, EPDM and/or NBR) that include silver-based compounds to provide highly desirable long-term antimicrobial characteristics within the cured rubber articles, at least a portion of which exhibits a color other than black, are provided. Such articles are in either solid or blown (foam or sponge) state (or combinations of both in multilayered forms, either all colored or individual layers colored) that can be utilized in a variety of different applications. As silver-based compounds are deleteriously affected by utilization of standard curing agents and curing accelerators, such as sulfur-based compounds and/or systems, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult. However, this invention encompasses the presence of different non-sulfur-based curing systems and agents, such as peroxides, as one example, that permit vulcanization and do not irreversibly bind silver ions thereto, thereby resulting in long-term antimicrobial performance of the ultimate rubber article itself. The rubber articles must also comprise fillers and may also include plasticizers to provide desired characteristics of dimensional stability, stiffness, flexural modulus, tensile strength, abrasion resistance, elongation, and the like, for the ultimate rubber article, while simultaneously and surprisingly both enhancing the control of antimicrobial efficacy of the rubber article and not deleteriously binding to the available silver to permit coloring of the target rubber as well.
摘要:
A stable, aqueous composition containing a substantially crosslinked alkali-swellable acrylate copolymer rheology modifier, a surfactant, an alkaline material, and various compounds therein, as for example substantially insoluble materials requiring suspension or stabilization, such as a silicone, an oily material, or a pearlescent material. Additionally, this invention also relates to the formation of a rheologically and phase stable cationic hair dye composition. The invention further relates to the incorporation of an acidic material after the addition of an alkaline material to reduce the pH of the composition without negatively impacting the viscosity of the composition.
