Patent ID: 8324312

Claim:
A treated liquid natural rubber latex composition comprising: field latex that has been treated, prior to vulcanization, with an aluminum hydroxide slurry and 0.1 parts per hundred rubber of surfactant, wherein the aluminum hydroxide slurry is a combination of 1 parts per hundred rubber of 10% ammonium hydroxide and 0.5 parts per hundred rubber aluminum hydroxide; less than 3 μg of antigenic protein per gram of composition; and depleted amounts of proteins, lipids, and lutoids as compared to the field latex prior to being treated, wherein the depleted amounts of proteins, lipids and lutoids in the treated liquid natural rubber latex composition results in improved optical properties of the treated liquid natural rubber latex as compared to the field latex prior to being treated, and wherein the improved optical properties are measured by noticing at least one of a cleaner appearance, reduced color, or increased translucency as compared to field latex prior to being treated.
