    摘要: A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a “dry liquid concentrate”, i.e., pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.

    摘要: An antimicrobial composition that involves a synergistic mixture in terms of active agents, of a primary antimicrobial agent, such as polyhexamethylene biguanide (PHMB), a secondary antimicrobial agent, and optionally an organic acid against various kinds of microbes is described. Various additional processing aids, such as alcohols and surfactants, may also be incorporated within the mixture. The composition allows one to use a significantly less concentration of individual constituent antimicrobial agents to achieve the same or a better degree of antimicrobial efficacy. The antimicrobial composition can be applied to the surface of almost any kind of substrate material, and can achieve a killing-efficacy of about 3 Log10 reduction in microbes within 30 minutes under ambient conditions.

    摘要: The present invention relates to a combination for surface treatment of a substrate, e.g. a nonwoven web, used in personal care product applications. The surface treatment combination not only provides adequate fluid handling properties, but also provides a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a skin health benefit agent on skin by an aqueous emulsion mediated dissolution of the agent from a substrate with subsequent transfer and deposition onto the skin. Coatings of the skin health benefit agent on the skin resist removal, thereby preventing damage to the natural skin barrier and providing a protective barrier against chemically- and biochemically-induced skin damage.
