Abstract: Provided are methods and compositions for reducing the protein content and/or undesirable odor of latex articles. The methods reduce the odor and/or protein content of latex articles by introducing compositions comprising a surfactant component and a potentiator into one or more stages of the manufacture of an article made of latex, or alternatively during the post laundering or washing treatment of the article. The potentiator comprises a chlorinating agent, a non-chlorinating salt, or a combination thereof. The methods and compositions are particularly applicable to natural rubber latex articles, especially those made through a dipping process.

Abstract: The present invention provides a ring-containing component polyol and process for making the same for use as a load-bearing capacity improvement agent in flexible polyurethane foam manufacture. The ring-containing component polyol eliminates and/or reduces the need for a copolymer polyol containing suspended solids in the manufacture of flexible foam products. This may reduce production costs, reactivity variations, filter plugging, color variations, foam shrinkage/tightness, foam irregularity, and foam malodor while maintaining an adequate load-bearing capacity. The present polyol blends can be non-opaque or transparent.

Abstract translation: 本发明提供含环元素多元醇及其制造方法，用于软质聚氨酯泡沫塑料制造中的承载能力改进剂。 含环组分多元醇消除和/或降低在制备柔性泡沫产品中含有悬浮固体的共聚物多元醇的需要。 这可以降低生产成本，反应性变化，过滤器堵塞，颜色变化，泡沫收缩/紧密度，泡沫不规则性和泡沫恶臭，同时保持足够的承载能力。 本发明的多元醇共混物可以是不透明或透明的。
