Abstract
A rubber latex composition is disclosed having reduced allergenicity. Methods for producing a rubber latex composition having reduced allergenicity are also disclosed.
Claims20
A treated liquid natural rubber latex composition comprising:
- field latex that has been treated with aluminum hydroxide and a surfactant;
- less than 10 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.
A treated natural rubber latex article comprising less than 10 μg/dm2 of antigenic protein and formed from a natural rubber latex composition treated with aluminum hydroxide at a concentration of at least about 0.01 parts per hundred parts of rubber and a surfactant, the treated natural rubber latex article having improved optical properties as compared with an untreated natural rubber latex article, wherein the improved optical properties results from the removal of antigenic proteins complexed with aluminum hydroxide, and the removal of proteins, lipids and lutoids that were present in the natural rubber latex composition prior to being treated.
A treated liquid natural rubber latex composition comprising:
- less than 10 μg of antigenic protein per gram of composition;
- and
- depleted amounts of proteins, lipids, and lutoids as compared to untreated field latex,
- wherein the treated liquid natural rubber latex has improved optical properties as compared to the untreated field latex.
