| abstract |
Hypoallergenic products are made from Parthenum argentatum (Gray), Ficus elastica and other non-hevea rubber-containing plants by homogenizing the plants in an aqueous medium, filtering the homogenate and separating the rubber-containing phase from the aqueous phase by centrifugation. Optionally, the filtrate may be clarified before separation. The hypoallergenic rubber products do not contain the rubber-associated proteins which are responsible for sensitization in allergic individuals. |
